Treating the continent as a single destination is the most expensive assumption a first-time exporter makes, because the four things that decide a shipment all vary by country and none of them is negotiable at the discharge port.
There are a few genuinely regional features, and they are worth stating before the differences swamp them. Outside South Africa, almost every road authority on the continent still specifies binder by penetration grade rather than by viscosity grade or performance grade, so 60/70 and 80/100 are the two names that appear on most tender documents from Dakar to Dar es Salaam. Heated shore tankage for imported binder is thin outside a handful of coastal terminals, which makes packed cargo the working default rather than the fallback. And a large share of demand comes from donor-funded or sovereign trunk-road programmes, where the specification written into the tender is the specification the resident engineer will actually test against, with very little room to substitute after award.
Beyond that, the differences dominate, and in this region they bite earlier than anywhere else, because the first of them has to be settled before the cargo is even produced. Kenya operates a pre-export verification programme whose output document is a Certificate of Conformity issued at origin by a body appointed by KEBS. Nigeria operates SONCAP, whose origin-side application is described as running off a Form M registered by the buyer’s bank. Egypt is generally described as operating no conformity certificate of that kind, but as requiring an ACID number on the shipping documents before loading. South Africa is generally described as operating none of the above and as relying on the laboratory data instead, in its own grade vocabulary. Whether any of those programmes catches your tariff line on your shipment date is a question for a licensed customs broker in the destination and never for a page like this one. Those are four incompatible pre-shipment workflows for four cargoes that might leave the same load port in the same week — and that is before the discharge port turns out to be in a different country from the buyer, or the paving window turns out to be November to March in northern Nigeria and October to March in the South African interior for reasons that have nothing to do with each other.
The distinguishing feature of African bitumen trade is pre-export conformity assessment. In an ordinary import, goods arrive and are then inspected, sampled or documented at the border; whatever goes wrong can usually be corrected at destination, expensively but possible. Under a pre-export conformity programme the sequence is inverted: the cargo is verified against the destination country’s own requirements while it is still in the country of export, and the certificate must exist before the vessel sails. Nothing at the discharge port can repair its absence. That inversion is the spine of this page, and it is the reason conformity belongs in the production schedule rather than in the documentation pack.
Africa has sixteen landlocked states — Botswana, Burkina Faso, Burundi, the Central African Republic, Chad, Eswatini, Ethiopia, Lesotho, Malawi, Mali, Niger, Rwanda, South Sudan, Uganda, Zambia and Zimbabwe — and several of the coastal states have their own demand concentrated hundreds of kilometres inland of their own ports. Kano is roughly a thousand kilometres from Lagos; Tamale is most of the length of Ghana from Tema; Johannesburg is inland of Durban by the whole width of KwaZulu-Natal and the Free State. The consequence is a rule that holds almost everywhere on this continent and almost nowhere else on this site: the port of discharge tells you where the cargo enters, not where it is going, and the leg after the port is usually the larger part of both the distance and the landed cost.
That single fact reorganises four separate decisions. It decides the packing, because a format that has to be kept hot cannot survive a multi-week road leg with border posts on it. It decides the customs procedure, because a cargo crossing a coastal state to reach an inland one is in transit there rather than imported, with a different declaration, a different bond and a different importer of record. It decides whose conformity programme governs, which is the destination’s and not the coastal state’s. And it decides which Incoterms rule is even coherent, because the sea rules stop at the ship’s rail and most of this journey happens on a truck. The corridor section below is the longest on this page for that reason.
Several African destinations operate mandatory pre-shipment verification programmes. The principle is stable and worth learning properly. The scheme names, the product scopes and the appointed inspection bodies are not stable, and must be confirmed shipment by shipment.
A pre-export conformity programme requires goods destined for the country to be verified against that country’s own standards before they leave the exporting country. An inspection body appointed by the destination’s standards authority carries out the verification and issues a certificate, and that certificate is what supports clearance at destination. A cargo that turns up without it is not merely delayed. Depending on the destination the consequences run to a penalty calculated on the customs value of the goods, compulsory destination inspection and testing at the importer’s cost, re-export at the shipper’s cost, or refusal of clearance outright.
There are perhaps a dozen of these programmes across the continent and no two carry the same name, but they are variations on one design. Learn the design and the individual scheme becomes a matter of filling in the blanks:
Two consequences follow that are worth stating plainly. First, a certificate issued under one country’s programme is not evidence under another’s, even where the two programmes look identical and are operated by the same inspection company. The certificate names a country, a standard and a consignment. Second, the programme that governs is the destination’s, not the coastal state the cargo transits, which is the single most common error on corridor business and is dealt with again in the corridor section below.
Most PVoC-style programmes offer the same three application routes, and choosing the wrong one, or choosing it late, is a common cause of schedule slippage:
Route A is the route that hurts a schedule, because every element of it — application, inspection booking, attendance, sampling, laboratory turnaround, certificate issue — happens serially and in full for every consignment. Route B and Route C are worth the set-up effort only for a specification that will ship repeatedly to the same destination, which on a project supply contract is often exactly what is happening. Decide which route you are on at the contract stage, because moving from A to B in the middle of a delivery programme does not retrospectively speed up the cargo already booked.
If your enquiry is for a destination this site does not cover, assume a programme of this family exists until a broker tells you otherwise, and ask early. Beyond the destinations set out above, programmes with the same architecture are operated under their own national names in a number of other African states: consignment-based conformity assessment arrangements appear in southern Africa, and pre-shipment conformity verification programmes administered by the national standards agency appear in several francophone West and Central African states, where the documentation and the correspondence will be in French and the standard verified against may be an EN standard adopted nationally rather than an ASTM one. The names, the scopes and the appointed bodies differ and are revised. This page names none of them for that reason, and neither should any offer document. Confirm with the destination standards authority or a licensed customs broker in the destination, for your product, your tariff line and your intended shipment date.
Whichever route applies, the file the appointed body opens is built from documents the seller has to have ready before the vessel is fixed. The set is recognisably the same set a dispute would need, which is the argument for building it properly whether a certificate is required or not:
Two reasons, both avoidable. The first is scope. Product scopes under these programmes are revised, and whether petroleum bitumen under HS 2713.20 is currently in scope for a given destination is a question with a current answer, not a permanent one. Assuming it is out of scope because a cargo cleared without a certificate last year is how a container ends up sitting at Apapa or Mombasa accruing storage. The second is timing. The certificate must be issued before shipment, which means the application, the inspection booking, the sampling, the laboratory turnaround and the certificate issue all have to fit between production and the vessel. Buyers who treat conformity as paperwork to be assembled alongside the bill of lading discover that it is a production-scheduling constraint instead.
Name the destination programme, name the certificate required, state which party applies and which party pays, and make the certificate a condition precedent to shipment rather than a document to be produced later. Where a letter of credit is used, list the certificate in the documentary requirements so it cannot quietly be omitted. Then confirm the current scheme, the current product scope and the currently appointed inspection body for your country of export before booking anything — with the destination standards authority or your broker, not from a page like this one. The export document set a conformity programme wants to see is largely the same set a dispute would need, which is a good reason to build it properly whether a certificate is required or not.
The order matters more than any individual step. Every one of these happens before the vessel sails, and each one has a lead time that belongs in the shipment schedule.
Establish that the destination operates a programme, that petroleum bitumen under HS 2713.20 is currently within its scope, which standard the cargo will be assessed against, and whether the application runs under Route A, B or C. This step determines everything downstream and is the one most often skipped.
Several programmes cannot start at origin until the importer has done something at destination. The references typically described are a Form M registered through an authorised dealer bank for Nigeria, an Import Declaration Form lodged on the single window for Kenya and an ACID number issued through Nafeza for Egypt, but the required reference for your destination is a broker’s answer. Ask the buyer for it before you apply, not after.
The application goes to a body appointed by the destination standards authority, not to an inspector of the exporter’s choosing. It is normally supported by the proforma invoice, the technical data sheet, the test report or Certificate of Analysis, the packing details and the buyer-side reference from the previous step.
The inspector attends before the containers are stuffed and sealed, verifies packing, marking, drum condition and quantity, and draws samples. For drummed cargo, sampling should be spread across the load rather than drawn from the drums nearest the container door, and retained samples should be sealed and held by both parties.
Samples are tested against the destination’s requirement, not against the exporter’s house specification. Where the destination limits a property your normal export specification does not report, the gap surfaces here — which is precisely why it is better to surface it at the load port than at the discharge port.
The Certificate of Conformity or equivalent is issued and its number is carried through the commercial documents. Only then does the cargo sail. At destination, clearance is presented against that certificate. If it does not exist, there is no retrospective cure and the destination’s penalty regime applies.
These are the eight African destinations compared side by side on this page; the site carries full country pages for these and for five more, all named in the routing section at the foot of the page. Take one row at a time. Column two decides what the resident engineer will test the binder against. Column three decides whether the cargo can lawfully sail at all. Columns four and five decide where it lands and how much further it still has to travel after that. No two rows here agree on all four, and two of the eight have no sea port of their own at all.
| Destination | Specification system procured against | Pre-export conformity requirement | Main sea port | Inland corridor from that port |
|---|---|---|---|---|
| Kenya | Kenya Standards (KS) issued by KEBS, a number of them adopted from East African Standards; road works to the Ministry Standard Specification for Road and Bridge Construction | PVoC administered by KEBS; Certificate of Conformity issued in the country of export by a KEBS-appointed body. The importer side normally also involves an Import Declaration Form lodged on the national single window | Mombasa | Northern Corridor: Nairobi, Nakuru, Eldoret, with onward transit to Uganda, Rwanda, Burundi, South Sudan and eastern DRC. Containers can also move by standard gauge rail to the inland container depots at Nairobi and Naivasha |
| Nigeria | Nigerian Industrial Standards (NIS) issued by SON; road works to the Federal Ministry of Works General Specification for Roads and Bridges | SONCAP administered by SON, in two stages: Product Certificate at origin, then the SONCAP Certificate that supports clearance. Tied to the importer Form M; a Pre-Arrival Assessment Report has featured on the Nigeria Customs side, so confirm the current document set before booking | Lagos — Apapa and Tin Can Island; also Lekki, Onne, Port Harcourt, Warri and Calabar | Lagos to Ibadan, Abuja and Kano on the western trunk route; eastern and southern cargo frequently routed via Onne to avoid the Lagos port access constraint |
| Ghana | Ghana Standards (GS) issued by the Ghana Standards Authority; road works to the Ministry of Roads and Highways and Ghana Highway Authority Standard Specification for Road and Bridge Works | Conformity assessment administered by the Ghana Standards Authority, with verification and certification at origin for regulated goods. Programme name and scope have been restructured in phases — confirm the version in force | Tema; Takoradi for the western region | Tema to Accra, Kumasi and Tamale; substantial transit traffic onward to Burkina Faso and Mali |
| Tanzania | Tanzania Standards (TZS) issued by TBS; road works to the TANROADS and Ministry of Works Standard Specification for Road Works | PVoC administered by TBS; Certificate of Conformity issued at origin before shipment | Dar es Salaam; Tanga for northern cargo | Central Corridor to Dodoma, Mwanza and the Isaka dry port for Rwanda and Burundi; TANZAM highway south to Zambia and Malawi |
| Uganda | Uganda Standards (US) issued by UNBS, a number of them adopted from East African Standards; road works to the general specification for road and bridge works issued by the ministry responsible for works, with the national roads function restructured in recent years | PVoC administered by UNBS; Certificate of Conformity issued at origin. This is Uganda’s programme, and it governs Uganda-bound cargo even though the goods transit Kenya or Tanzania on the way | None — landlocked. Mombasa or Dar es Salaam is the gateway | Northern Corridor from Mombasa via Nairobi, Eldoret and the Malaba or Busia crossing to Kampala, of the order of 1,150 km; or the Central Corridor from Dar es Salaam via the Mutukula crossing. Uganda is the one market on this table with a genuine choice of two oceans |
| South Africa | SANS 4001-BT1 for penetration grade binders, with COLTO standard specifications, SANRAL and provincial project specifications, and Sabita technical guidelines | Not generally described as operating a pre-export programme of the PVoC or SONCAP type. Compulsory specifications sit with the NRCS; a paving binder is usually evidenced by testing to the SANS method suite at accredited laboratories. Confirm scope with a South African clearing agent rather than assuming it either way | Durban, including the Island View liquid bulk precinct; also Cape Town, Gqeberha, Richards Bay and East London | N3 corridor Durban to Johannesburg and the Highveld; onward road transit to Botswana, Zimbabwe, Mozambique, Eswatini and Lesotho |
| Egypt | Egyptian Standards (ES) issued by EOS; road works to the Egyptian code for road works and the specifications of the national roads authority | Not generally described as PVoC. The mechanism described is an ACID registered through the Nafeza single window before loading, with the number carried on the shipping documents; GOEIC registration and inspection requirements are described as applying to specified goods | Alexandria and El Dekheila; also Damietta, Port Said and Ain Sokhna | Delta road network and the Cairo–Alexandria desert road; Red Sea coast and Upper Egypt routes from Ain Sokhna |
| Ethiopia | Ethiopian standards issued by the national standards body; road works to the Ethiopian Roads Authority standard technical specification and manual series | Landlocked, so the cargo transits Djibouti before it is imported. Conformity assessment is handled through the national conformity assessment body; confirm the current requirement with a corridor clearing agent | No sea port — Djibouti, principally Doraleh, is the gateway | Djibouti–Dire Dawa–Adama–Addis Ababa corridor, roughly 900 km by road, with the Addis Ababa–Djibouti railway as an alternative leg |
Fourteen gateways on four coasts — the Indian Ocean, the Red Sea and Gulf of Aden, the Gulf of Guinea and the Atlantic, and the Mediterranean. They are named as market geography, not as an arrangement at any facility, and nothing here states that any of them is open, equipped for this commodity or available on your date. Every gateway below handles containers as ordinary business, which is why drummed bitumen reaches every destination on this page without special provision at the quay. Heated shore tankage for imported binder is a different question entirely: where it exists it belongs to a refiner, an importer or a terminal operator with their own throughput to move. So the question is never whether the port has tanks somewhere — it is whether this particular buyer holds a tank allocation, a discharge window and heated road tankers behind it, in writing, before the vessel is fixed. If not, the cargo should be packed.
The Northern Corridor gateway, and the container entry point for a great deal more than Kenya. It serves Kenya and, under customs transit, Uganda, Rwanda, Burundi, South Sudan and eastern DRC, so a large share of what lands there never clears in Kenya at all. Containers can move inland by road or by standard gauge rail to the Nairobi and Naivasha inland container depots. Packed cargo is the practical option for anything continuing up-country.
The Central Corridor gateway, serving Tanzania plus transit traffic to Rwanda, Burundi, Zambia, Malawi and eastern DRC, with the Isaka dry port used as an inland break-bulk point for the Great Lakes destinations. The TANZAM highway runs south from here. Tanga takes smaller northern cargo. Drums dominate anything moving beyond the coastal strip.
The main Nigerian container gateways, sitting inside the Lagos road network, where access has been a structural constraint rather than an occasional one and truck movements have been placed under an electronic call-up arrangement whose current form your forwarder should confirm. Container free time is consumed by port access as much as by the road leg. Build the terminal-side dwell into the free time you negotiate, not just the haul.
Lekki is the newer deep-water facility east of Lagos; Onne, Port Harcourt, Warri and Calabar serve the south and east. Cargo for eastern and southern Nigeria is frequently routed away from Lagos for access reasons alone. Where the project is in the north, the decisive number is the road leg to Abuja or Kano and whether the cargo lands in time for the northern dry season.
Tema is the principal container gateway for Accra, Kumasi and the north, and carries transit traffic onward to Burkina Faso and Mali through the Paga crossing. Takoradi serves the western region. Customs processing runs through Ghana’s national integrated customs platform, which has been changed and re-tendered more than once; the clearing agent will handle it, but the exporter’s document set has to match whichever version is in force exactly.
Durban is the main gateway, and its Island View liquid bulk precinct is why South Africa is the one market on this page where a buyer asking about a bulk parcel is asking a routine question rather than an ambitious one. That says nothing about whether any particular buyer holds an allocation there, which still has to be in writing before a vessel is fixed. Cape Town, Gqeberha, Richards Bay and East London serve their own hinterlands. The N3 to Johannesburg is the corridor that matters for the Highveld.
Alexandria and the adjacent El Dekheila handle the bulk of Mediterranean import traffic, with Damietta, Port Said and Ain Sokhna serving the Delta, Suez and Red Sea flows. Egypt has a long-established domestic refining and asphalt industry, which means an imported cargo arrives into a market that already has its own binder supply rather than into a gap — the commercial case for importing usually has to be specific, and any bulk discharge arrangement has to be confirmed by the buyer in writing rather than inferred from the presence of the industry. Everything also hangs on the ACID number being registered before loading.
Ethiopia has no coastline, so Ethiopian cargo discharges in Djibouti and then crosses an international border under transit before it is imported. That is two customs jurisdictions on one shipment before the consignee sees the goods. The corridor to Addis Ababa runs roughly 900 km by road, with the Addis Ababa–Djibouti railway as an alternative. Plan from the gateway, not from the destination.
The principal francophone gateway on the Gulf of Guinea and the ocean end of the Abidjan–Ouagadougou corridor, which exists as both a trunk road and a metre-gauge railway running north through Bouaké and Ferkéssédougou into Burkina Faso. From Ferkéssédougou a western branch runs toward Mali. San Pédro serves the south-west. Two practical consequences for an exporter: the tender, the correspondence and the conformity file will be in French, and the grade named will be an EN band such as 35/50 or 50/70 rather than 60/70.
The westernmost gateway on the continent and the ocean end of the Dakar–Bamako road corridor, of the order of 1,250 km by way of the Kayes axis and the Diboli crossing. The historic Dakar–Niger railway on metre gauge has been out of through service for long periods, so the corridor should be planned as a road corridor unless a forwarder says otherwise in writing. Dakar matters mainly because of Mali: a Bamako buyer has four or five plausible gateways and is comparing corridors rather than suppliers.
Two Gulf of Guinea gateways whose commercial logic is almost entirely about what lies behind them. Lomé is the ocean end of a corridor running north to Ouagadougou through the Cinkassé crossing; Cotonou is the ocean end of the corridor to Niamey through Malanville. For a Burkina Faso or Niger project the live comparison is between Tema, Lomé, Abidjan and Cotonou, and it is settled on the inland leg, the border count and the transit regime rather than on the ocean freight.
The gateway for Cameroon and for two landlocked interiors at once. North-east through Ngaoundéré and Garoua the corridor continues to N’Djamena in Chad, of the order of 1,900 km and the longest of the West and Central African corridors on this page; east through Garoua-Boulaï and the Beloko crossing it reaches Bangui in the Central African Republic. A metre-gauge railway runs inland from Douala to Ngaoundéré and the remainder is road. On a leg of that length the packing decision is not a preference.
Three gateways on one coast, each serving a different foreign hinterland rather than each other. Beira faces Zimbabwe through the Machipanda crossing to Mutare and Harare and continues to Zambia through Chirundu; Nacala faces Malawi through the Cuamba and Entre Lagos axis; Maputo faces Gauteng and Eswatini through the Ressano Garcia and Lebombo crossing on the N4. For Malawi and for much of Zambia these are materially shorter than either Dar es Salaam or Durban, which is why a Blantyre or Lusaka enquiry should always be priced against more than one gateway.
The Atlantic option for the southern African interior, and the one gateway on this page that is chosen for what it avoids rather than for what it is near. The Trans-Kalahari Corridor runs inland through Windhoek and the Buitepos and Mamuno crossing to Gaborone and on to Gauteng; a second routing runs north-east through Katima Mulilo toward Livingstone, Lusaka and the Copperbelt. Distances are long — Gaborone and Lusaka are both well over 1,500 km — so it competes on border count and predictability rather than on kilometres.
Africa spans roughly 37 degrees of latitude north and 35 south, crosses the equator, and contains the largest hot desert on earth alongside two extensive highland plateaux where nights are genuinely cold. That is why a single continental grade recommendation is not merely imprecise, it is wrong in at least three of the bands below. Temperature on this continent is set by altitude and humidity far more than by latitude, and the two properties that matter to a binder are not the same property: the daytime maximum drives rutting, and the night-time minimum together with the size of the daily swing drives thermal cycling and fatigue. The band that catches exporters is the fourth one, because the cargo usually arrives through a hot lowland port and is then hauled a thousand kilometres to a site where the binder question has inverted. Locate the project by town and altitude before agreeing a grade, and read the note below before assuming the export certificate covers what the site needs.
| Climate band | Where it runs | Temperature and rainfall character | What it does to a binder | Grade direction, and what the certificate must carry |
|---|---|---|---|---|
| The Saharan interior | The Sahara and its margins: the Algerian, Libyan and Egyptian deserts, Mauritania, northern Mali, northern Niger, northern Chad and northern Sudan | The most extreme diurnal range on the continent. Very high summer daytime maxima with very low humidity and intense solar radiation, and winter nights in the deep interior that fall to or below freezing | Two opposite demands on the same material. By day the pavement is at the severe end of the rutting case; over twenty-four hours the binder cycles further than anywhere else in Africa, which is a thermal fatigue problem rather than a rutting one; and in winter the low-temperature end of the specification stops being a formality | Harder grade for the summer case, but this is one of only three bands on this page where a low-temperature line has to be added to the certificate by written agreement — Fraass breaking point to EN 12593, or a bending beam rheometer requirement under AASHTO M320. No standard penetration-grade export sheet carries one |
| The Sahel | The belt running from Senegal and southern Mauritania across Mali, Burkina Faso, Niger and northern Nigeria to Chad and Sudan | One short rainy season, broadly June to September, and a long dry season either side of it. The Harmattan, a dry dust-laden north-easterly, blows roughly November to February. The hottest months are the pre-rain months of March to May rather than midsummer | Sustained high pavement temperature with a wide daily swing but without the humidity of the coast. The dominant practical effect is not on the binder at all but on the calendar: the entire year’s paving is compressed into the dry window, so material has to be pre-positioned rather than called off | Harder grade, and measured penetration and softening point on a batch certificate rather than a reprint of the band, because the position inside the band is a real performance variable at these temperatures. Harmattan dust is an aggregate-coating and mix-quality problem, not a binder problem, and no binder certificate addresses it |
| The humid tropical belt | The Gulf of Guinea coast from Guinea through Nigeria to Cameroon, the Congo basin, and the East African coastal strip from Somalia to Mozambique | High daytime maxima and, decisively, high night-time minima, with humidity high all year. Rainfall in much of the West African south is bimodal, with a major season broadly April to July and a minor one broadly September to November | The most severe version of the rutting case, because the pavement does not cool down between days and the binder sits at high temperature for long unbroken periods. Alongside it sits the durability problem that defines this band: moisture damage, water working into the mix and stripping the binder film off the stone | Harder grade or a modified binder where the pavement is also heavily loaded. The moisture question is answered in the mix and never on a binder certificate — commission affinity testing to EN 12697-11, or moisture-induced damage to AASHTO T283 on the compacted mix, using the actual project aggregate. This is also the most aggressive storage environment on the continent for packed goods: heat, humidity and salt-laden air attack drum seams and closures, so covered storage and short dwell are not refinements |
| The East African highlands | The Ethiopian plateau, broadly 1,600 to 2,500 m with Addis Ababa at around 2,355 m; the Kenyan highlands with Nairobi at around 1,800 m and Eldoret at around 2,100 m and the trunk road crossing the Mau uplands above 2,500 m; the Rwandan and Burundian hills with Kigali at around 1,500 m; the Ugandan plateau with Kampala at around 1,200 m; and the Tanzanian southern highlands | Cool days and genuinely cold nights the year round, with a large diurnal range and ground frost recorded at the highest cultivated altitudes. Rainfall is bimodal in the equatorial part of the band and single-season further north | The band that inverts the usual African assumption. Pavement temperatures here are far below coastal values, the rutting argument weakens, and thermal cycling with cool nights becomes the governing case. A binder chosen for the port the cargo landed at is the wrong material for a site 1,500 m above it | Softer grade — this is where 80/100 legitimately appears in Kenyan, Tanzanian and Ethiopian tenders — and a low-temperature line agreed in writing for sites above roughly 2,000 m. The trap is structural: the cargo arrives through Mombasa, Dar es Salaam or Djibouti, all of them hot lowland gateways, so the corridor climate and the project climate are two different questions and only the second one decides the grade |
| The southern African Highveld | The interior plateau of Gauteng, the Free State, the Mpumalanga highveld and the Northern Cape interior, generally 1,200 to 1,800 m with Johannesburg at around 1,750 m; and the whole of Lesotho, whose lowest point is at around 1,400 m | Hot summers with summer rainfall broadly October to March, and a real winter from around May to August with frost, sub-zero nights and snow on the Drakensberg and in the Lesotho highlands | The widest span of service temperature of any band on this page, which is the direct reason the South African specified range is wider than anywhere else in Africa. Summer demands rut resistance on heavily loaded freight corridors; winter demands that the binder not become brittle | The full SANS range is in play: 35/50 for hot and heavily loaded interior work, 50/70 as the mainstream, 70/100 for cooler work. The binding construction constraint in winter is ambient and surface temperature limiting compaction, not rainfall, which is a different scheduling logic from every other band on this page |
| Mediterranean North Africa and the Egyptian Delta | The Mediterranean littoral and the Nile Delta, with the Egyptian interior shading into the Saharan band described above | Hot dry summers and mild wet winters. No monsoon and no rainy season in the tropical sense. Spring brings the khamsin, a hot dust-laden wind off the desert | Very high summer pavement temperature with negligible low-temperature cracking risk, so effectively the entire design pressure sits on rutting resistance and none of it on thermal cracking. This is the simplest binder case on the continent | Harder grade, with 40/50 appearing where the design calls for it. Effectively a year-round working season, with the practical caution being not to commit surfacing work to the spring dust season. No low-temperature line is needed here, which is what distinguishes this band from the Saharan interior a few hundred kilometres south of it |
| The winter-rainfall corner: the Western Cape | The south-western tip of South Africa around Cape Town and the coastal belt east of it | A Mediterranean pattern running opposite to the rest of the country: rainfall concentrated May to August, with a dry summer working season. Cooler than the interior in summer and milder than it in winter | Milder service temperatures than the Highveld at both ends, which is why the softer end of the South African range appears here while the interior specifies harder | 70/100 appears in Western Cape work where the interior would specify 50/70 or 35/50. The scheduling consequence is national rather than regional: a South African supply programme runs against two opposed seasonal calendars in one country, and a delivery window agreed against one of them is wrong for the other |
| The cool Atlantic coastal strip | The Namibian and southern Angolan coast, including Walvis Bay, under the influence of the cold Benguela current | Cool, foggy and very dry, and materially cooler than the desert a short distance inland. An unusual band for its latitude | Named because it is a storage and staging environment rather than a paving market of its own. Cargo entering the interior through this coast is landed in a cool damp environment and hauled into a hot dry one within a day | Not a grade-selection band. The grade is set by the destination inland, which is Botswana, Gauteng or the Zambian Copperbelt — not by the port. It is a useful reminder that on this continent the climate at the gateway almost never decides the specification |
Grade choice across the region tracks pavement temperature and axle loading, not preference. Timing tracks rainfall — except in interior South Africa, where it tracks temperature. Both belong in the shipment plan rather than in the schedule argument afterwards.
| Destination | Grade normally specified | Why that grade | Construction season | Practical shipment window |
|---|---|---|---|---|
| Kenya | 60/70, with 80/100 on lighter work and at altitude | Hot lowland corridors and heavy commercial axle loading on the Northern Corridor favour the harder grade; the highlands around Nairobi and Eldoret sit well above 1,500 m and run materially cooler, which is where the softer grade appears | Long rains March to May; short rains October to December | Aim to clear Mombasa ahead of the long rains. June to September is the broadest paving window |
| Nigeria | 60/70 for asphaltic concrete; MC-30 and MC-70 cutback for prime coat | Sustained high pavement temperatures with heavy commercial loading on the trunk routes, against a specification written in penetration grades rather than viscosity or performance grades | South: wet April to October with a short August break. North: rains June to September, then Harmattan November to February | Northern dry-season paving runs November to March, so arrival and inland haulage have to be ahead of it |
| Ghana | 60/70; 80/100 on lighter work and surface dressing | The coastal south is hot and humid year round and the northern savannah hotter and drier; both sit comfortably in mid-range penetration territory | South is bimodal — major rains April to July, minor rains September to November. North: May to October | December to March is the reliable dry window, particularly in the north |
| Tanzania | 60/70, with 80/100 where the specification allows | Dar es Salaam and the coastal strip are hot and humid, while much of the interior is high plateau and materially cooler, so grade choice tracks project altitude as much as latitude | North bimodal, March to May and October to December; centre and south November to April | June to October is the broadest dry window across the Central and TANZAM corridors |
| Uganda | 60/70 on trunk work, with 80/100 where the plateau altitude and lighter loading allow | The whole country sits on a plateau, with Kampala at around 1,200 m, so pavement temperatures are moderate by African standards and the governing case is heavy commercial axle loading on the corridor trunk routes rather than extreme heat | Bimodal near the equator: rains broadly March to May and September to November, with the north running a single season roughly April to October | December to February and June to August are the working windows, but the binding constraint is corridor arrival — the haul from Mombasa or Dar es Salaam has to be finished before the window opens, not started when it does |
| South Africa | 50/70 as the mainstream grade, 35/50 for heavily loaded and hot interior work, 70/100 for cooler and Western Cape work | SANS 4001-BT1 uses EN-style bands, so 60/70 is not a South African grade name at all. The Highveld is hot in summer and frost-prone in winter, which is why the specified range is wider than anywhere else in the region | Summer rainfall interior October to March; Western Cape winter rainfall May to August | Interior asphalt laying is limited by winter ambient and surface temperature, not only by rain. The two halves of the country run opposite seasons |
| Egypt | 60/70; harder grades such as 40/50 where the design calls for them in the hottest areas | Very high summer pavement temperatures with negligible low-temperature cracking risk, so effectively the whole design pressure sits on rutting resistance | No monsoon. The constraints are winter night temperatures and the spring khamsin dust winds | Effectively year round; avoid committing surfacing work to the spring dust season |
| Ethiopia | 60/70 and 80/100 depending on altitude | Most of the populated plateau sits between roughly 1,600 and 2,500 m and runs far cooler than the Djibouti lowlands the cargo passes through, so a high-altitude project can legitimately call for a softer binder than the corridor climate would suggest | Main kiremt rains June to September; belg rains February to May | October to May is the working season, and corridor haulage from Djibouti also eases once the kiremt ends |
This is the single most useful thing a continental page can explain, because it is the part of African trade that a supplier page normally skips and a buyer cannot. Most of Africa’s binder demand is inland. A coastal port is therefore a gateway rather than a destination, and the corridor behind it — not the port — decides the cost, the packing, the customs procedure and which country’s conformity programme applies. What follows is the map, corridor by corridor, with the landlocked countries each one actually serves. Nothing here states that any road, crossing, railway or service is open, running or willing to carry this commodity on your date; that is a freight forwarder’s answer in writing.
The word corridor is used loosely in trade literature, but the main African corridors are institutional arrangements rather than descriptions of tarmac. Each has a treaty or protocol behind it, a secretariat, a harmonised transit declaration, a guarantee mechanism standing in for the duties that would fall due if the goods never left, seals and in several cases electronic cargo tracking, one-stop border posts where two administrations work in a single stop, and harmonised axle-load rules enforced at weighbridges along the route. That matters commercially for a reason most first-time exporters miss: the transit regime, not the haulage rate, is what determines who is liable while the cargo is between countries, what document releases it, and where the movement has to be discharged.
Three of these institutions come up constantly. The Northern Corridor Transit and Transport Coordination Authority has its secretariat in Mombasa and its member states are commonly listed as Burundi, the Democratic Republic of the Congo, Kenya, Rwanda, South Sudan and Uganda. The Central Corridor Transit Transport Facilitation Agency has its secretariat in Dar es Salaam and covers Burundi, the DRC, Rwanda, Tanzania and Uganda. In West Africa, road transit between the coastal states and the Sahel runs under the ECOWAS inter-state road transit arrangements, known in the francophone documentation as the TRIE convention, with a single transit document and a guarantee chain between national bodies, alongside harmonised axle-load rules adopted at UEMOA level. In East Africa the East African Community single customs territory arrangements mean the duty on transit goods belongs to the destination partner state rather than to the coastal state the cargo passes through. In southern Africa the equivalent framework is the SADC transit arrangement and the North–South Corridor programme. No figures for bond values, guarantee costs, axle limits or transit times appear on this page; they are questions for a licensed clearing agent and a carrier.
The road and rail axis running inland from Mombasa through Nairobi, Nakuru and Eldoret to the Ugandan frontier at Malaba or Busia, and onward through Kampala. Beyond Kampala it branches: south-west into Rwanda at Gatuna and Katuna or at Kagitumba and Mirama Hills, and on to Kigali, then into Burundi at Nemba or Akanyaru for Bujumbura; north through Gulu to Elegu and Nimule for Juba; and west into the eastern Democratic Republic of the Congo at Rubavu, the Rwandan town formerly called Gisenyi, for Goma, and at Rusizi, formerly Cyangugu, for Bukavu.
Landlocked countries it serves: Uganda, Rwanda, Burundi, South Sudan, plus the eastern provinces of the DRC, whose own Atlantic coastline is on the far side of the Congo basin and is not a realistic alternative for them. Commonly cited road distances from Mombasa put Nairobi at roughly 480 km, Kampala at roughly 1,150 km, Kigali at roughly 1,700 km, Juba at roughly 1,800 km by the Ugandan routing and Bukavu at roughly 2,000 km.
Two structural facts belong to this corridor. The first is the break of gauge inside Kenya: the standard gauge railway built to 1,435 mm runs from Mombasa to Nairobi and on to a terminus near Naivasha, with inland container depots at both; the legacy network that historically continued from Nakuru through Eldoret to Malaba and into Uganda is metre gauge at 1,000 mm. A through rail movement to the Ugandan frontier therefore has a transhipment hidden inside it, and every transhipment is a handling event where drums are dented and counts are disputed. The second is that the destination’s conformity programme governs: a Uganda-bound cargo is subject to Uganda’s programme through UNBS, not Kenya’s through KEBS, even though it lands at Mombasa and spends a week on Kenyan roads.
The axis running west from Dar es Salaam through Morogoro, Dodoma, Singida and Nzega to the Isaka dry port, and from there to Rusumo for Rwanda, to Kabanga and Kobero for Burundi, and to Mutukula for Uganda. It also has two lake legs that have no equivalent anywhere else in African bitumen logistics: from Mwanza across Lake Victoria toward Port Bell and Jinja in Uganda and Kisumu in Kenya, and from Kigoma across Lake Tanganyika toward Bujumbura, Kalemie in the DRC and Mpulungu in northern Zambia.
Landlocked countries it serves: Rwanda, Burundi, Uganda in its western half, and the eastern DRC; the Lake Tanganyika leg also reaches the northern tip of Zambia. Commonly cited road distances from Dar es Salaam put Kigali at roughly 1,400 km and Bujumbura at roughly 1,500 km.
The commercial significance of the Central Corridor is that it makes Rwanda and Burundi genuinely contestable. For Uganda, Mombasa is the natural axis. For Kigali and Bujumbura the two corridors compete on comparable distances, and a buyer there will be comparing gateways rather than suppliers. If your offer is built on Mombasa, expect to be measured against a Dar es Salaam alternative, and expect the comparison to be decided on the inland leg and the frontier count rather than on the ocean freight.
The same port, a different direction. The trunk road runs south-west through Morogoro, Iringa and Mbeya to the frontier at Tunduma and Nakonde, and on to Lusaka and the Zambian Copperbelt, continuing to Kasumbalesa for the Katanga province of the DRC. Alongside it runs the TAZARA railway from Dar es Salaam to Kapiri Mposhi in Zambia, built to 1,067 mm Cape gauge — a third gauge in the same region, and the reason there is no single rail system spanning East and Southern Africa. A branch from Mbeya reaches the Malawian frontier at Songwe for Karonga and the northern lakeshore.
Landlocked countries it serves: Zambia and Malawi, plus the Congolese Copperbelt. Commonly cited road distance from Dar es Salaam to Lusaka is roughly 1,900 km, which is the longest of the East African corridor legs and the strongest single argument on this page for packed cargo.
West Africa has a structure found nowhere else on the continent: a set of roughly parallel north–south corridors running from the Gulf of Guinea into the Sahel, competing for the same three landlocked destinations. Burkina Faso, Mali and Niger each have several plausible gateways, and the choice between them is a live commercial decision rather than a geographical given.
Two features distinguish West Africa from the eastern corridors and both change the paperwork. The first is the anglophone and francophone split. Ghana and Nigeria issue tenders in English in the penetration idiom inherited from British practice; Côte d’Ivoire, Togo, Benin, Senegal, Mali, Burkina Faso and Niger issue them in French, and the binder will be named on an EN band such as 35/50 or 50/70 rather than as 60/70. A single corridor can therefore start in one vocabulary and finish in another. The second is that the conformity programme of the coastal state is not the one that governs, exactly as in East Africa, so a cargo entering through Tema for a Ouagadougou project is a Ghanaian transit and a Burkinabé import, and the pre-shipment certification question has to be put to a broker in Ouagadougou rather than in Accra.
The southern African system is the one where the drums-versus-bulk balance shifts most, because haulage capability near the coast is genuinely different from the rest of Africa. It is built around one dominant axis and four alternatives that exist to avoid it.
Two southern destinations are special cases worth naming. Lesotho is entirely surrounded by South Africa, so every import is a South African transit before it is a Lesotho import, entering at crossings such as Maseru Bridge or Ficksburg; and because the country’s lowest point is at around 1,400 m, it is also the coldest destination on this page, which pulls the grade the opposite way from the rest of the continent. Eswatini is surrounded by South Africa and Mozambique and is reached from Durban or Maputo. In both cases the practical supply route is usually a road movement out of South Africa rather than a separate ocean cargo, which is a different transaction with a different document set.
Two corridors serve a single landlocked country each, and both are worth stating separately because the country behind them has no alternative at all. Djibouti, principally at Doraleh, is the gateway for Ethiopia: the road corridor through Dire Dawa and Adama to Addis Ababa is commonly cited at roughly 900 km, with the standard-gauge Addis Ababa–Djibouti railway as an alternative leg. Douala is the gateway for two: north-east through Ngaoundéré and Garoua to N’Djamena in Chad, commonly cited at roughly 1,900 km and the longest of the West and Central African corridors on this page, and east through Garoua-Boulaï and Beloko to Bangui in the Central African Republic. A metre-gauge railway runs from Douala to Ngaoundéré and the remainder is road.
Rail appears in almost every corridor description and almost never as a single-mode movement, for a reason that is easy to check and easy to miss. Three different track gauges are in commercial use on the corridors described above: 1,435 mm standard gauge on the Kenyan standard gauge railway, on the newer Tanzanian standard gauge line, on the Addis Ababa–Djibouti line and in Egypt; 1,067 mm Cape gauge across southern Africa, on the TAZARA line and on the Angolan Benguela alignment inland from Lobito; and 1,000 mm metre gauge on the legacy Tanzanian central line, the legacy Kenya–Uganda line, the Abidjan–Ouagadougou line, the Douala–Ngaoundéré line and the historic Dakar–Niger alignment. Note that Tanzania and Kenya each run a standard gauge line alongside a legacy metre gauge one, so a single country can contain the break. Where a plan crosses systems it crosses gauges, and a gauge change is a physical lift. For drummed cargo that is not fatal, but it is one more handling event to record a count at.
For a cargo as heavy and as low in value density as binder, the ocean freight is the smaller half of the transport question and the road haul is the larger half for every inland destination on this page. A price quoted to a gateway port is a proper offer and it is not a delivered price, and two offers can only be compared if they are expressed to the same named place. Say which it is in the offer, and agree an Incoterms 2020 rule that reflects where risk and cost actually change hands rather than a sea rule applied to a truck.
Sixteen African states have no coastline, and two of the eight markets compared above are among them. Their cargo discharges at somebody else’s port and then travels 600 to 1,900 km by road under a foreign customs regime. That leg, not the sea freight, decides the packing, and the decision is made on physics rather than on price.
Botswana, Burkina Faso, Burundi, the Central African Republic, Chad, Eswatini, Ethiopia, Lesotho, Malawi, Mali, Niger, Rwanda, South Sudan, Uganda, Zambia and Zimbabwe all import bitumen through a coastal gateway in a neighbouring country. The ocean voyage is the short, cheap, predictable part of the journey. The inland leg is longer, slower, dearer per tonne and far less forgiving of anything that has to be maintained in transit.
A bitutainer or heated tank container is an excellent answer on a short, well-equipped route. Over a long inland corridor it accumulates problems:
Drummed bitumen travels cold, tolerates weeks in transit and repeated handovers, needs no heating equipment or receiving tank at destination, splits into small lots for project sites scattered along a corridor, and is handled with a forklift or by hand where no forklift exists. The empty steel drum also carries a local resale value at destination, which is a genuine part of the economics on these routes even though it never appears in a quotation. That is why drummed supply dominates inland African destinations while bulk is confined to the coast.
The published loading figures used across this site are: 150 kg new steel drums — 80 drums and 12 MT per 20’ FCL; 180 kg drums — 80 drums and 14.4 MT; 185 kg drums — 80 drums and 14.8 MT; jumbo or poly bags of 1 MT — 20 bags and 20 MT; and a bitutainer at 20 to 25 MT. On a corridor route the heavier drum sizes are usually right where the destination road weight limits allow them, because packing cost per tonne falls while the inland handling profile is unchanged. Specify new steel drums explicitly. Reconditioned drums are the most common single source of contamination disputes, and on a corridor route a leaking drum is discovered a very long way from anyone who can do anything about it. The mechanics of stuffing, securing and sealing are covered on the containerised shipment page.
This is where planning goes wrong most often. For a Uganda-bound cargo through Mombasa, it is Uganda’s conformity programme that governs the goods, because Uganda is the destination; Kenya’s role is transit. The cargo moves under a regional transit regime with its own declaration, bond, seals and electronic cargo tracking, and in East Africa the duty belongs to the destination partner state under the customs union arrangements rather than to the coastal state the cargo passes through. Two documentary streams therefore run in parallel, and getting the destination certificate right while getting the transit documentation wrong strands the cargo just as effectively as the reverse.
Container free time and detention are being consumed by a road journey measured in weeks rather than the days a coastal delivery assumes. Negotiate free time against the corridor, not against the port. And agree an Incoterms 2020 rule that reflects where risk and cost genuinely change hands: a CIF price to a gateway port tells a buyer in Kigali or N’Djamena almost nothing about landed cost, and it is the point at which the inland leg either becomes somebody’s stated obligation or becomes nobody’s.
Sixteen African states have no coastline, and every one of them buys binder through somebody else’s port. This table is the routing reference for the whole page: it names the gateway or gateways that actually serve each one, the corridor between them, an indicative road distance and the packing that survives the leg. Distances are commonly cited road approximations for planning discussion only; actual routing, crossings and conditions are a freight forwarder’s answer in writing, and no transit times appear anywhere. Read the second column carefully — where it names more than one gateway, the enquiry should be priced against at least two, because on these distances the corridor decides the landed cost and the ocean leg does not.
| Landlocked destination | Usual gateway port or ports | Corridor | Indicative road distance | Practical packing and the point that decides it |
|---|---|---|---|---|
| Botswana | Walvis Bay, Namibia; or Durban, South Africa; in practice a great deal of supply moves by road out of Gauteng | Trans-Kalahari Corridor from Walvis Bay via Windhoek and the Buitepos and Mamuno crossing to Gaborone; or the North–South Corridor from Durban through Gauteng and the Groblersbrug and Martin’s Drift crossing | around 1,000 km from Durban; around 1,700 km from Walvis Bay | Drums. Botswana sits close enough to the South African road network that the real comparison is often against a road movement out of Gauteng rather than against another ocean gateway |
| Burkina Faso | Tema or Takoradi, Ghana; Abidjan, Côte d’Ivoire; Lomé, Togo; Cotonou, Benin | Tema via Kumasi, Tamale and the Paga crossing; Abidjan via Bouaké and Ferkéssédougou by road or metre-gauge rail; Lomé via Cinkassé | around 1,000 km from Tema; around 1,150 km from Abidjan | Drums. Four plausible gateways make this the most contested routing in West Africa. Note the vocabulary split: the gateway may be anglophone but the tender will be in French and will name an EN band |
| Burundi | Dar es Salaam, Tanzania; Mombasa via the Northern Corridor as the alternative | Central Corridor via Dodoma and Nzega to the Kabanga and Kobero crossing for Bujumbura, with the Kigoma axis and Lake Tanganyika as a second leg | around 1,500 km from Dar es Salaam; around 2,000 km from Mombasa | Drums, in lot sizes the receiving site can actually handle. Three or four frontiers on the Mombasa routing and one on the Dar es Salaam routing is a bigger difference than the 500 km |
| Central African Republic | Douala, Cameroon | Douala to Garoua-Boulaï and the Beloko crossing, then Bangui | around 1,500 km | Drums, in small deliverable lots. One gateway and no realistic alternative, so the corridor is the whole plan rather than one variable in it |
| Chad | Douala, Cameroon | Douala–Ngaoundéré–Garoua–N’Djamena, with a metre-gauge rail leg as far as Ngaoundéré and road beyond it | around 1,900 km | Drums. The longest mainstream corridor named on this page, into a Sahelian destination with a compressed dry-season paving window |
| Eswatini | Durban, South Africa; or Maputo, Mozambique | Road inland from Durban through the South African network, or the short leg west from Maputo | around 600 km from Durban | Drums, though the practical route is frequently a road movement out of South Africa rather than a separate ocean cargo, which is a different transaction with a different document set |
| Ethiopia | Djibouti, principally Doraleh | Djibouti–Dire Dawa–Adama–Addis Ababa, with the standard-gauge Addis Ababa–Djibouti railway as an alternative leg | around 900 km | Drums. Two customs jurisdictions on one shipment, and a plateau destination between roughly 1,600 and 2,500 m that is far cooler than the corridor crossing the Afar lowlands to reach it |
| Lesotho | Durban, South Africa | Inland from Durban through the South African network to crossings such as Maseru Bridge and Ficksburg | around 600 to 700 km to Maseru | Drums. Entirely surrounded by South Africa, so every import is a South African transit before it is a Lesotho import. With the country’s lowest point at around 1,400 m it is also the coldest destination on this page, and the grade argument runs the opposite way from the rest of the continent |
| Malawi | Nacala or Beira, Mozambique; also Dar es Salaam | Nacala corridor via Nampula, Cuamba and the Entre Lagos and Nayuchi crossing to Liwonde, Blantyre and Lilongwe; Beira corridor via Tete and Zóbuè to Blantyre | around 800 to 1,000 km from Beira or Nacala | Drums. The Mozambican gateways are decisively shorter than either Dar es Salaam or Durban, so a Lilongwe enquiry priced only from Dar es Salaam is usually being priced on the wrong corridor |
| Mali | Dakar, Senegal; Abidjan, Côte d’Ivoire; Tema or Lomé through Burkina Faso; Conakry, Guinea | Dakar–Kayes–Diboli–Bamako; Abidjan–Ferkéssédougou–Bamako; or the Ghanaian and Togolese routes through Bobo-Dioulasso | around 1,250 km from Dakar; around 1,200 km from Abidjan | Drums. More gateway options than any other landlocked country on the continent, which is precisely why a Bamako buyer is comparing corridors rather than suppliers |
| Niger | Cotonou, Benin; Lomé, Togo through Burkina Faso; Lagos, Nigeria through Kano | Cotonou–Malanville–Niamey; or Lagos–Ibadan–Abuja–Kano and the Jibiya or Illela crossing toward Maradi and Birni N’Konni | around 1,050 km from Cotonou to Niamey; roughly 1,000 km Lagos to Kano before the frontier is reached | Drums. A Sahelian destination whose entire paving programme sits inside the dry window, so material is pre-positioned rather than called off against a schedule |
| Rwanda | Mombasa, Kenya; or Dar es Salaam, Tanzania | Northern Corridor to Kigali through the Gatuna and Katuna or Kagitumba and Mirama Hills crossings; or Central Corridor via the Isaka dry port and the Rusumo crossing | around 1,700 km via Mombasa; around 1,400 km via Dar es Salaam | Drums. The most genuinely contested routing in East Africa, so compare total landed cost to a named place in Kigali rather than sea freight to a port |
| South Sudan | Mombasa, Kenya; Juba also draws cargo through Ethiopia and from Port Sudan | Northern Corridor via Eldoret and Kampala to the Elegu and Nimule crossing; a direct Kenyan alignment runs through Kitale, Lodwar and the Nakodok crossing | around 1,700 to 1,800 km by the Ugandan routing | Drums, in small deliverable lots. A Juba enquiry is one where the buyer may be comparing gateways in three different directions rather than comparing suppliers |
| Uganda | Mombasa, Kenya; or Dar es Salaam, Tanzania | Northern Corridor via Nairobi, Eldoret and the Malaba or Busia crossing to Kampala; or the Central Corridor through the Mutukula crossing, with a Lake Victoria leg from Mwanza to Port Bell as a further alternative | around 1,150 km from Mombasa | Drums. Uganda operates its own PVoC programme through UNBS, separate from Kenya’s and Tanzania’s — the destination’s programme governs, not the gateway’s |
| Zambia | Dar es Salaam, Tanzania; also Durban, Beira, Nacala, Walvis Bay, or Lobito in Angola as the Atlantic option promoted for the Copperbelt | TANZAM highway to the Tunduma and Nakonde crossing for Lusaka and the Copperbelt, with the TAZARA railway alongside it; or the North–South Corridor from Durban through Beitbridge and Chirundu; or the Walvis Bay corridor through Katima Mulilo and Livingstone; or the Lobito corridor east from the Angolan coast through Benguela and Huambo. Whether the Lobito routing is usable for this commodity on your date is a forwarder’s answer in writing | around 1,900 km from Dar es Salaam | Drums, unless the buyer operates a heated depot at destination and confirms it in writing. More gateways than any other southern African destination, and the longest legs of any of them |
| Zimbabwe | Beira, Mozambique; or Durban, South Africa | Beira corridor via the Machipanda crossing and Mutare to Harare; or the North–South Corridor from Durban through Gauteng and the Beitbridge crossing | around 600 km from Beira to Harare; around 1,700 km from Durban | Drums. Beira is much the shorter leg, so a Harare enquiry priced only from Durban is usually being priced on the wrong corridor |
| Eastern and southern DRC — Goma, Bukavu and the Katanga Copperbelt | Mombasa or Dar es Salaam for Goma and Bukavu; Durban, Dar es Salaam, Walvis Bay or Lobito in Angola for Lubumbashi | Northern Corridor through Rwanda to the Rubavu and Rusizi crossings; Central Corridor with a Lake Tanganyika leg; the North–South Corridor to the Kasumbalesa crossing; or, for the Katanga province, the Lobito corridor inland from the Angolan coast on the Benguela alignment through Luau and Dilolo | around 1,850 km to Goma and around 2,000 km to Bukavu from Mombasa | Drums. Not a landlocked country but a landlocked demand region: the DRC’s own Atlantic coastline is on the far side of the Congo basin and is not a practical alternative for these provinces. Confirm the final frontier procedure with a clearing agent there, because the regional arrangements that make an East African movement orderly cannot be assumed to apply in the same form |
This is the second thing that makes the continent illegible to a first-time exporter. There is no African grading system. There are four, they coexist along the same corridors, and the grade name at the top of a tender tells you which family the engineer is working in before it tells you anything about the binder. Anglophone Africa inherited the penetration idiom of former British practice and the tropical design guidance written for it. Francophone Africa inherited French practice, which has since been absorbed into the European standard and its bands. South Africa developed a national system of its own with its own designations, its own test-method suite and its own modified-binder classification. And the export trade writes its certificates in the ASTM idiom, which is what most offers arrive in whatever the tender says. On top of all four, performance grading appears wherever an international consultant designs the project. A grade in one system cannot be inferred from a grade in another, because the name is only the penetration line and every other acceptance limit — flash point, solubility, ductility, ageing — comes from whichever requirement table the clause intends.
| System | Where it appears in Africa | Grade names it actually contains | Governing and design documents | What an exporter has to do about it |
|---|---|---|---|---|
| Former British practice: the penetration idiom | Kenya, Uganda, Tanzania, Ghana, Nigeria, Zambia, Malawi, Zimbabwe, Botswana, Sudan and most of anglophone Africa | The names in circulation are 60/70, 80/100 and 40/50, quoted as penetration at 25 °C in tenths of a millimetre | The historic British standard for bitumens for road purposes, BS 3690, from which the practice descends, has been withdrawn and superseded by EN 12591. Design reasoning comes from the TRL tropical guidance — Overseas Road Note 31 on the structural design of bitumen-surfaced roads in tropical and sub-tropical countries and Overseas Road Note 3 on surface dressing — sitting under each country’s general specification for road and bridge works | The trap here is 80/100, which belongs to no current standard at all. ASTM D946 names 85-100 and EN 12591 names 70/100, and neither contains a band called 80/100. A batch at 82 dmm satisfies a literal 80/100 and EN 70/100 but fails ASTM 85-100 outright. Establish which requirement table the clause intends before the batch is certified. Note also that ORN 3 is why cutback and emulsion appear so often in these tenders: a large part of these networks is surface dressed rather than surfaced in asphalt concrete |
| Former French practice, now expressed on EN bands | Senegal, Mali, Burkina Faso, Niger, Côte d’Ivoire, Benin, Togo, Guinea, Cameroon, Chad, the Central African Republic and the Maghreb | The EN 12591 bands: 20/30, 30/45, 35/50, 40/60, 50/70, 70/100, 100/150, 160/220 and 250/330. The three in bold carry most ordinary road work | EN 12591, paving grade bitumens, adopted nationally. The older French specification for pure bitumens named grades of the 40/50 and 80/100 family and has been superseded by the European standard, so a legacy clause may cite a document that no longer exists in the form the clause assumes. Design guidance descends from the French tropical pavement design tradition rather than from the British one | Two things. First, do not translate 60/70 into 50/70 by assumption: every genuine 60/70 batch sits inside the 50/70 penetration band, but the containment runs one way only and the other limits are the EN ones. Second, and more often missed, EN 12591 controls ageing by the rolling thin-film oven procedure to EN 12607-1, whereas an ASTM D946 export certificate normally carries a thin-film oven result to ASTM D1754. Those are different exposures and their results are not interchangeable, so add the test before the batch is certified. Expect the tender, the correspondence and the conformity file to be in French |
| The South African system | South Africa, and influential across Namibia, Botswana, Lesotho and Eswatini | SANS 4001-BT1 penetration bands: 35/50, 50/70 and 70/100. There is no 60/70 and no 80/100 in the system | SANS 4001-BT1 for the binder and the SANS 3001 series for test methods, with the predecessor compendium TMH1 still cited in older tender packs. Above them sit the COLTO standard specifications and the newer COTO set, the TRH series — TRH 3 on surfacing seals, TRH 4 on flexible pavement design, TRH 8 on hot-mix asphalt, TRH 14 on materials — SANRAL’s pavement engineering manual, and the manual series published by Sabita, the Southern African Bitumen Association, including TG1 on modified binders and TG2 on bitumen stabilised materials | Offer the designation the tender uses. Writing 60/70 on a document intended to satisfy a SANS clause names a grade the governing document does not contain, which is a compliance problem before it is a technical one. The predecessor specification did name 60/70 and 80/100, which is why those names still surface in legacy drawings and maintenance records — that is a question for the engineer, not something to resolve by assumption. Expect testing to the SANS method suite at an accredited laboratory and expect the data to be checked line by line |
| ASTM and AASHTO export practice | The idiom most export certificates are written in, and the one an African tender is most often measured against. Egyptian practice also leans on ASTM test methods | ASTM D946 penetration grades 40-50, 60-70, 85-100, 120-150 and 200-300; AASHTO M20 names the same bands with a hyphen. Viscosity grading under ASTM D3381 and AASHTO M226 appears on some donor-financed and South Asian-influenced work | ASTM D946 and AASHTO M20 for the grades. Test methods: ASTM D5 penetration, ASTM D36 softening point, ASTM D113 ductility, ASTM D92 flash point, ASTM D2042 solubility, ASTM D70 specific gravity, ASTM D1754 thin-film oven, ASTM D2872 rolling thin-film oven, ASTM D95 water content | Two points of convention that cause more argument than they should. ASTM D946 sets a lower minimum flash point of 232 °C for the mainstream paving grades than the 250 °C typically printed on an export data sheet, and it expresses the ageing requirement as a minimum retained penetration after the thin-film oven test rather than as a maximum drop. The two conventions describe the same measurement but they are not the same number. And a clause naming grade 60-70 is not naming something different from what the trade calls 60/70 — same band, same needle test at 25 °C, different punctuation |
| Performance grading, on internationally designed work | Appears anywhere on the continent that an international consultant designs and supervises the project, and increasingly on heavily loaded urban and industrial pavement | AASHTO M320 performance grades written as a high-temperature and a low-temperature number, and AASHTO M332 grades based on multiple stress creep recovery | AASHTO M320 and AASHTO M332, with the supporting test suite: dynamic shear rheometer, rolling thin-film oven, pressure ageing vessel and bending beam rheometer | A performance grade cannot be inferred from a penetration grade and the reverse is equally false. They are different measuring systems answering different questions. A penetration-grade export certificate carries none of the data an M320 clause requires, so if the tender is performance graded the test schedule has to be agreed and run before the batch is certified. This is also the system in which a high-temperature grade is often reached by polymer modification rather than by a stiffer base binder, which is a question worth asking explicitly |
It is the one African market with a mature national binder standard of its own, a different grade vocabulary, real heated import infrastructure and a procurement culture that looks nothing like the rest of the continent.
South Africa specifies penetration grade binders under SANS 4001-BT1, which uses EN-style bands: 35/50, 50/70 and 70/100. There is no 60/70 in that system. A cargo offered as 60/70 straddles the 50/70 and 70/100 bands and sits cleanly inside neither, which is a materially different problem from the usual equivalence discussion — it is not that the grades are hard to compare, it is that the name on your certificate does not exist in the buyer’s standard. If your material genuinely meets the 50/70 band, offer it as 50/70 and evidence it with test data. Do not offer 60/70 and expect the band to be read generously. This single point is true of South Africa and false of every other country on this page.
South Africa is not generally described as operating a pre-export conformity programme of the PVoC or SONCAP type. Compulsory specifications sit with the National Regulator for Compulsory Specifications (NRCS), and a road paving binder is usually described as handled through specification compliance and testing rather than through an origin-country certificate. If that description holds for your product, the practical consequence is a reversal of emphasis rather than a lighter burden: less pre-shipment certification, considerably more scrutiny of the test data itself and of the laboratory that produced it. It is not a finding that your product sits outside every scheme — confirm the position for your specific product and tariff line with a South African clearing agent before assuming it either way. The governing document stack behind the binder — COLTO and COTO, the SANRAL and provincial project specifications, the TRH series and the Sabita guidelines — is set out in the grading systems table above and in full on the country page.
The buying side is concentrated and technically capable — a national roads agency, provincial authorities, and a set of large contractors and binder suppliers who run their own laboratories and expect supplier data to withstand being checked line by line. Supplier prequalification, traceable batch data and a defensible document set matter more here than anywhere else in the region, and a Certificate of Analysis whose numbers sit suspiciously in the middle of every specification band will be treated as a finding rather than a reassurance.
South Africa is also the one market where bulk is a normal option rather than a stretch, because heated import and storage infrastructure exists at the coastal terminals in a way it does not further north. South African refining capacity has been widely reported to have contracted through refinery closures and conversions in recent years, which is the background to a larger imported share of binder and to the technical seriousness of import discussions there. Treat that direction as reported rather than as a figure this page can support. Discharge is principally at Durban, with Cape Town, Gqeberha, Richards Bay and East London serving their own hinterlands.
The two opposed seasonal calendars this country runs on — a Highveld winter that limits compaction by ambient and surface temperature, and a Western Cape winter rainfall pattern with a summer working season — are set out in the climate band table above, and matter here only as a warning against promising a national delivery window against one of them. The South Africa page covers the standard, the grades, the test suite and the ports in full, and this section deliberately stops short of it.
For several of them, yes. Kenya, Nigeria, Tanzania, Ghana and Uganda all operate programmes under which regulated goods must be verified and certified in the country of export before shipment. Whether petroleum bitumen under HS 2713.20 falls within the current scope for a given destination is a question with a current answer rather than a permanent one, so confirm it with the destination standards authority or a licensed customs broker for every shipment. Do not rely on a previous cargo having cleared without one.
Kenya operates PVoC through KEBS, producing a Certificate of Conformity. Nigeria operates SONCAP through SON, with a Product Certificate obtained at origin followed by the SONCAP Certificate. Tanzania operates PVoC through TBS. Ghana runs a conformity assessment programme through the Ghana Standards Authority, restructured in phases in recent years. Uganda operates PVoC through UNBS, which applies to Uganda-bound cargo even though it transits Kenya. Egypt uses a different mechanism with the same timing logic: an ACID number registered through the Nafeza single window before loading. South Africa is not generally described as operating an equivalent general programme, but confirm that with a South African clearing agent rather than assuming it. Names, scopes and appointed bodies change, so treat all of this as orientation and put the current position for your tariff line to a licensed customs broker in the destination.
It depends on the destination, and none of the outcomes are good. The common consequences are a penalty calculated on the customs value of the goods, compulsory destination inspection and testing at the importer cost, re-export at the shipper cost, or refusal of clearance. The critical point is that there is no retrospective cure. The certificate has to be issued in the country of export before shipment, so it cannot be obtained after arrival.
They are the three application routes most of these programmes offer. Route A is consignment by consignment, with every shipment inspected and tested individually; it is the slowest and where a first-time exporter normally starts. Route B is product registration, where a product with an established test history is registered in advance and subsequent consignments are verified more lightly. Route C is licensing of the manufacturer based on an assessment of the facility and its quality system, with the lightest per-consignment burden. Choosing the route late is one of the main causes of schedule slippage.
Outside South Africa, 60/70 is the mainstream paving grade across the region, with 80/100 appearing on lighter work, on surface treatments and on higher-altitude projects in Kenya, Tanzania and Ethiopia where the pavement runs cooler. Egypt may specify a harder grade such as 40/50 for the hottest conditions. South Africa is the exception: it uses EN-style bands under SANS 4001-BT1, so the grades named there are 35/50, 50/70 and 70/100. In every case, supply the grade the project specification names and get any substitution approved in writing.
Because the inland leg is 800 to 1,900 km of road haulage under a foreign customs regime. Drums travel cold, tolerate weeks in transit and multiple handovers, need no heating equipment or receiving tank at destination, and split into small lots for project sites spread along a corridor. A heated tank unit by contrast must stay pumpable or be reheated, needs heated storage at the receiving end, sits closer to enforced axle-load limits, and must then make the whole inland journey again empty while accruing demurrage. The empty steel drum also has local resale value at destination, which is a real part of the economics.
No, and it is worth being precise about this. SANS 4001-BT1 uses EN-style bands, so the South African grade names are 35/50, 50/70 and 70/100 and there is no 60/70 in the system. A 60/70 cargo straddles the 50/70 and 70/100 bands and sits cleanly inside neither. If your material meets the 50/70 band, offer it as 50/70 and evidence it with test data rather than offering 60/70 and expecting the band to be interpreted generously.
Petroleum bitumen sits under HS heading 2713.20, and the code is one of the very few things on this page that is the same for every destination. What differs is what hangs off it: the national subheading, the duty treatment, and above all whether that code currently falls inside the destination conformity scheme scope, which is the question worth asking your broker first. On a transit shipment the duty belongs to the destination country under the customs union arrangements rather than to the coastal state the cargo passes through, so the classification your transit agent in Mombasa or Dar es Salaam uses and the one your Kampala or Kigali clearing agent uses have to agree. On loading, the figures used across this site are 80 drums of 150 kg for about 12 MT per 20-foot container, 80 drums of 180 kg for about 14.4 MT, 80 drums of 185 kg for about 14.8 MT, 20 jumbo or poly bags of 1 MT for about 20 MT, or a bitutainer at 20 to 25 MT. The difference in Africa is that the binding number is frequently not the container at all but the enforced axle load at a weighbridge several hundred kilometres inland, so settle the destination road weight limit with the buyer before choosing the drum size.
Start by establishing which corridors physically reach the destination, because for most landlocked African states there is more than one. Rwanda and Burundi are reachable from Mombasa or Dar es Salaam; Zambia from Dar es Salaam, Durban, Beira, Nacala or Walvis Bay; Malawi from Nacala, Beira or Dar es Salaam; Zimbabwe from Beira or Durban; Botswana from Walvis Bay or Durban; Burkina Faso from Tema, Abidjan, Lome or Cotonou; Mali from Dakar, Abidjan, Conakry or through Burkina Faso; Niger from Cotonou, Lome or through Kano. Uganda, Ethiopia, Chad and the Central African Republic are the cases where there is essentially one answer, and there the corridor is the whole plan rather than one variable in it. Then compare on four things rather than on ocean freight. First, the inland distance to a named delivery place rather than to a port. Second, the frontier count: a thousand kilometres across three customs territories is a different proposition from a thousand kilometres inside one, because each frontier is a declaration, a guarantee arrangement, a set of agents and a place where a discrepancy stops a vehicle. Third, the transit regime and who provides the guarantee, which has a value and a cost and is discharged only at a nominated exit office. Fourth, where the container is stripped and who pays for the empty leg back, because on a corridor haul the round trip is measured in weeks. Ask a forwarder to price both gateways to the same named place, in writing. Anything else is not a comparison.
Quote in the words the tender uses, and settle in writing which requirement table it intends, because 50/70 and 60/70 belong to different standards and are not translations of each other. 50/70 is an EN 12591 band; 60/70 is an ASTM D946 grade. On penetration alone the ASTM window sits wholly inside the EN band, so every genuine 60/70 batch satisfies the 50/70 penetration line, but that containment runs one way only and it says nothing about the rest of the table. The material difference is the ageing procedure: EN 12591 controls resistance to hardening by the rolling thin-film oven method to EN 12607-1, whereas an ASTM D946 export certificate normally carries a thin-film oven result to ASTM D1754. Those are different exposures and the results are not interchangeable, so where the clause is an EN clause the RTFOT has to be added to the test schedule before the batch is certified rather than argued about afterwards. The flash point convention also differs: D946 sets a minimum of 232 degrees C for these grades while export data sheets commonly print 250. State on the offer which specification the material is certified to, print the measured penetration and softening point from a batch-specific Certificate of Analysis, and obtain the engineer written approval for any cross-reference before dispatch. On a corridor shipment that written approval is worth more than usual, because a rejection happens a very long way from anyone who can do anything about it.
A hub’s job is to make the continent legible and then get out of the way. Each page below carries the national standard, the grades actually named in it, the ports, the corridor and the import procedure in full, at a level of detail this page deliberately does not attempt. Open the one that matches your destination, and if your destination is landlocked, open the page for the country your cargo will be hauled through as well.
The pages above are the African markets this site covers in full, and the corridor table further up this page routes every one of the sixteen landlocked African states to the gateway that serves it. For a destination without a page — a Ouagadougou, Bamako, Lusaka or Harare project, or anything reached through a gateway state we do cover — work from the corridor table for the routing, from the climate band table for the grade direction, and from the conformity section for the mechanism, then put the current scheme scope and tariff classification to a licensed customs broker in the destination before booking. The markets we serve index lists every destination page on the site.
Send the destination country and the final delivery point, the grade and the governing specification, tonnage, packing and Incoterm. If the destination operates a pre-export conformity programme, say so in the enquiry so the certification lead time is built into the shipment plan from the start rather than discovered against a vessel booking.
