Bitumen Supply to Mozambique: Maputo, Beira, Nacala and the Corridors

Mozambique occupies the whole western shore of the Mozambique Channel, from the South African frontier in the extreme south to the Rovuma river and the Tanzanian frontier in the far north. The coastline is commonly given as roughly 2,500 km, which is a long way even by African standards: the distance from Maputo to Pemba by the national trunk road is greater than the distance from Mombasa to Kigali. A country of that shape does not have a hinterland. It has several, and they are reached through three separate port and rail systems that face inland at three different sets of neighbours.

• The southern system, at Maputo and Matola. It sits at the bottom of the country, roughly ninety kilometres from the South African frontier at Ressano Garcia, and its natural inland market is not southern Mozambique alone but the industrial region of Gauteng around Johannesburg and Pretoria, together with Eswatini. Maputo is closer to Johannesburg than it is to Beira.
• The central system, at Beira. It is the sea end of the shortest route from the Indian Ocean to Zimbabwe, through Manica province and the frontier at Machipanda, and the corridor road continues inland through Chimoio, from where the trunk road toward Tete branches north-west through Catandica and Changara to the Zambezi crossing, and from Tete the frontiers with Malawi, Zambia and northern Zimbabwe are reached. Beira is the only one of the three systems that reaches three landlocked countries from a single inland axis, which is why Tete, the town where that axis divides toward Malawi, toward Zambia and toward northern Zimbabwe, carries a disproportionate share of the corridor traffic and appears repeatedly on this page.
• The northern system, at Nacala. It is routinely described as the deepest natural harbour on this coast, and it faces west across Nampula and Niassa at Malawi and, beyond Malawi, northern Zambia. It is also the port furthest from the rest of Mozambique’s own demand.

The four landlocked countries in question are Malawi, Zambia, Zimbabwe and Eswatini. Malawi is landlocked in a way that is unusually complete: every sea route it has runs through Mozambique or through Tanzania. Zimbabwe has Beira as its shortest ocean access and Durban as its established alternative. Zambia has more choices than any of them, with Beira, Nacala, Dar es Salaam and Walvis Bay all competing for the same tonnage. Eswatini is small, wholly enclosed by South Africa and Mozambique, and inside the Southern African Customs Union. Beyond those four sit the Copperbelt and, at the far edge of the Beira corridor’s reach, the mining region of the southern Democratic Republic of the Congo.

The structural fact that surprises first-time shippers: the three systems do not connect

Mozambique’s railways are administered by the state ports and railways company, Portos e Caminhos de Ferro de Moçambique, commonly abbreviated CFM, which is organised in southern, central and northern regions for exactly this reason. Each region is a network that runs inland from its port to a frontier. They are not joined to one another inside Mozambique. There is no rail spine down the coast. A wagon at Nacala cannot be railed to Beira, and a wagon at Beira cannot be railed to Maputo, without leaving the country. The only continuous north to south link is the national trunk road, the EN1, which runs the length of the country and crosses the Zambezi by bridge at Caia.

Two things follow for a buyer. The first is that the port decision is irreversible in practice. On a coastline with a connecting railway a mis-routed cargo is an expensive nuisance; here it is a journey of well over a thousand kilometres by road down a single trunk route. The second is that the three systems compete with different rivals rather than with each other. Maputo competes with Durban and Richards Bay. Beira competes with Durban for Zimbabwe and with Dar es Salaam for Zambia. Nacala competes with Beira and with Dar es Salaam for Malawi. A buyer in Lilongwe is not choosing between Mozambican ports and foreign ones as a single question; they are choosing inside a set of options whose members change with the destination.

One gauge, which is the compensating advantage

Against that disconnection sits a genuine technical advantage that East African corridors do not have. The railways of Mozambique are built to Cape gauge, 1,067 mm, and so are the railways of South Africa, Zimbabwe, Zambia, Malawi, Eswatini and Botswana. Southern Africa is, in gauge terms, a single system. There is no break of gauge on the frontier of the kind that forces a physical transhipment inside Kenya, and a through rail movement from a Mozambican port to an inland destination is technically coherent in a way it is not on the Northern Corridor. Whether such a movement is available for this commodity, in your packing, on your date, is an operating question for a freight forwarder and this page asserts nothing about it. But the underlying compatibility is real, it is stable, and it is worth knowing before a forwarder conversation rather than after.

Why the inland leg dominates the arithmetic

Bitumen is heavy and low in value density. A tonne of paving grade binder is worth a small fraction of a tonne of most cargo that travels in a container and weighs exactly the same, so freight is a large share of landed cost rather than a rounding error. On every one of these corridors the inland portion is not a final delivery charge; for the landlocked destinations it is most of the distance. Commonly cited road distances, given for orientation only, put Johannesburg at roughly 550 km from Maputo, Mutare at roughly 290 km and Harare at roughly 600 km from Beira, Blantyre at roughly 800 km and Lilongwe at roughly 1,000 km from Beira through Tete, and Lilongwe at roughly 1,000 km from Nacala by the northern route. No figure is offered here for Lusaka or the Copperbelt, because the direct routing through Tete and the routing through Zimbabwe differ substantially and both are longer than any of the destinations named above; take those two from the forwarder rather than from a page. Those figures vary with the alignment actually used and an actual routing has to come from a forwarder, but the shape of the problem is unmistakable: for an inland buyer the ocean freight is the smaller half of the transport question and the road or rail haul is the larger half.

The commercial consequence is blunt. A quotation expressed CIF Beira is a proper offer, and for a Sofala project it is close to a delivered price. For a project in Lusaka it prices the part of the journey that is easiest to price and leaves the frontier-crossing, weighbridge-controlled, guarantee-backed part of it entirely open. Any serious comparison of two offers into the interior has to be made on the same basis, at the same named place, or it is not a comparison at all. This is why the first question on a Mozambican enquiry is not grade or tonnage. It is where the material is actually being used, and the second is which of the three systems serves it.

The domestic Mozambican market underneath the corridor traffic

Mozambique is a substantial road market in its own right, and its demand has a particular shape. The classified national network is administered by the national roads administration, the Administração Nacional de Estradas, commonly abbreviated ANE, with maintenance funded through a dedicated road fund; municipal and provincial authorities run their own urban and local programmes; and a significant proportion of trunk work is designed and supervised under donor and development-bank financing, which brings international consultants and their specification traditions with it. The practical result is the same as in every market of this kind: there is no single national specification practice to quote against. A municipal resurfacing package in Maputo, an ANE trunk contract on the EN1, a provincial low-volume sealed road project and a consultant-designed corridor rehabilitation can each carry a different binder clause, a different set of cited test methods and a different view on modified binder.

Three features of the demand are worth a supplier knowing. First, a large part of the network is surface dressed rather than surfaced in asphalt concrete, which pulls cutback and emulsion into enquiries far more often than a pure hot-mix market does, and which means prime coat is a live line item on almost every project with new granular base in it. Second, the country is long and thin and the sites are spread along it, so material is pre-positioned rather than called off on a short cycle, and the packing has to store well. Third, the southern market has a real overland alternative that the centre and the north do not: southern Mozambique sits on the doorstep of the South African industrial region, so a Maputo-area buyer is comparing a seaborne import against a road movement across one frontier, while a Nampula buyer has no such option.

The five things that decide a Mozambican order

• Which system, and is the cargo staying? Maputo, Beira or Nacala, and is the material for use in Mozambique or moving in transit to Malawi, Zambia, Zimbabwe or Eswatini? This decides the customs procedure, the importer of record, the guarantee, the conformity question and the documents.
• The named delivery place, not the country. Maputo, Chimoio, Tete, Nampula, Blantyre, Lilongwe, Harare and Ndola are entirely different propositions. An enquiry naming only a country cannot be priced, only guessed at.
• Which climate zone the site is in, and at what altitude. The Mozambican coast is hot and humid at sea level, the Zambezi valley at Tete is the hottest ground in the country, and the corridor destinations beyond the frontier sit on plateaux above a thousand metres. These push the grade in different directions.
• Which conformity regime applies, and whose. Mozambique has its own arrangements and so do the destinations beyond it. Evidence produced for one is not automatically evidence for another, and the current scope of any of them is a question for a licensed customs broker in the destination.
• The language the documents will actually be read in. Portuguese in Mozambique, English in Malawi, Zambia, Zimbabwe and Eswatini. A corridor consignment crosses that boundary in the middle of its journey, which is a documentation problem with a specific and avoidable failure mode.

What this page does not tell you

It does not state that any port, berth, terminal, road, railway, bridge, border post or corridor service is open today, running to a schedule, equipped for this commodity or available for your cargo. Geography is stated because geography is stable and publicly checkable; operating status is not, it changes, and it belongs to the freight forwarder who is accountable for it. Road distances are commonly cited approximations for orientation and nothing more. No transit times, freight rates, vehicle payloads, vessel or tanker capacities, port throughput, draught or berth figures, container free time periods, detention charges, duty rates, taxes or levies appear anywhere. No refinery, terminal operator, concessionaire, shipping line, haulier, forwarder, inspection body, clearing agent, product brand or client is named as a counterparty, and no presence, office, agency or shipping history in Mozambique or in any corridor country is claimed. Climate is described as climate: the cyclone season of this ocean basin is a meteorological fact about the basin and is not a statement that any port or route is affected, closed or available on any date. It states no position on whether bitumen is or is not currently within the scope of any conformity assessment programme, and it names no currently appointed inspection body, for the reasons set out at length in the conformity section. It quotes no Mozambican national standard designation for paving bitumen, because the requirement that binds a shipment is the clause the tender incorporates. And nothing here is legal, customs, regulatory, insurance or compliance advice; a buyer trading across these frontiers must take independent advice covering the goods, the parties, every customs territory on the route and the payment mechanism.

The ports themselves, described as public geography

Mozambique’s commercial ports are administered within the framework of the state ports and railways company, Portos e Caminhos de Ferro de Moçambique (CFM), with individual facilities operated under various long-standing arrangements. The principal facilities are at Maputo, including the adjacent terminals at Matola; at Beira, at the mouth of the Pungue estuary in Sofala; and at Nacala, on a deep natural bay in Nampula province. Secondary ports include Quelimane in Zambézia, Pemba in Cabo Delgado, Inhambane and Angoche.

The inference an enquiry most often makes wrongly is from the word deep. Nacala is routinely described as the deepest natural harbour on the eastern African coast, and buyers move from that statement straight to an assumption about what can be discharged there. Heated tankage, drum handling equipment, covered storage and the ability to receive a particular packing are contracted commercial arrangements with individual terminal operators. They are never attributes that can be inferred from a bay’s bathymetry, from a port’s name, or from the fact that a port handles other petroleum products. Bathymetry tells you what a vessel can approach; it tells you nothing about whether a bitumen parcel can be discharged, heated, stored and released. Confirm what the receiving facility can actually do for your product and your packing, in writing, before a parcel is fixed. Nothing on this page states that any Mozambican facility handles bitumen, and no facility named here is a counterparty of ours.

Rail: one gauge, three networks, and what that combination means

The southern network runs inland from Maputo on three axes: the Ressano Garcia line to the South African frontier, the Goba line to Eswatini, and the Limpopo line north-west through Chicualacuala to the Zimbabwean frontier. The central network runs inland from the Beira area on two axes: the Machipanda line through Chimoio to the Zimbabwean frontier, and the Sena line north-west to Moatize in Tete, with a branch toward the Malawian frontier. The northern network runs inland from Nacala through Nampula and Cuamba to the Malawian frontier at Entre Lagos, and continues through Malawi toward Moatize.

All of it is Cape gauge, 1,067 mm, and so are the networks it runs into at every one of these frontiers: South Africa, Eswatini, Zimbabwe, Zambia and Malawi, with Botswana on the same gauge beyond them. The one qualification is Tanzania, Mozambique’s remaining neighbour and the alternative gateway for Malawi and Zambia: its own national line is metre gauge and its newer line is standard gauge, and only the Tanzania–Zambia railway, which runs inland from Dar es Salaam to Kapiri Mposhi in Zambia and meets the Zambian network there rather than reaching the Copperbelt itself, shares the southern African gauge. The shared gauge is the compensating advantage set against the disconnection described above, and it is worth stating precisely because it inverts the East African situation. On the Northern Corridor a container railed inland from the coast meets a change of gauge inside Kenya and has to be physically transhipped. In southern Africa a wagon that starts at a Mozambican port is, in gauge terms, compatible with the track all the way to Johannesburg, Harare, Lilongwe, Lusaka or the Copperbelt.

Three consequences follow for a bitumen consignment. First, a through rail movement is technically coherent here in a way it is not on some other African corridors, which makes it worth asking a forwarder about rather than dismissing. Second, technical coherence is not availability: whether a service runs, whether it accepts this commodity in your packing, what the wagon or container arrangement is and what it costs are operating and commercial questions that this page does not answer and that change. Third, every mode change is a handling event, and handling events are where drums are dented, seams are stressed and counts are disputed. A packing specification adequate for a single door-to-door road movement is not automatically adequate for a movement that is lifted three or four times.

The roads, the river crossings and the weighbridges

The EN1 is the national north to south trunk road and the only continuous domestic link between the three systems; it crosses the Zambezi by bridge at Caia. The EN4 runs from Maputo to the South African frontier at Ressano Garcia and continues as a toll route on the South African side. The EN6 runs inland from Beira through Dondo and Chimoio to the Zimbabwean frontier at Machipanda. West of Chimoio the traffic for Tete leaves the EN6 and turns north-west through Catandica and Changara toward the Zambezi crossing at Tete, and that is the axis from which the Malawian and Zambian frontiers are reached. This page gives no route number for the Tete road: numbering and reclassification change, and a road code printed here and relied on in a routing instruction would be worth less than the town names either side of it. Ask the forwarder to state the alignment by name and by number in writing.

Two physical characteristics matter to a heavy consignment. The Beira and Nacala corridors both climb: they begin at sea level and end on plateaux well above a thousand metres, with the sharpest gradients on the escarpment sections near the frontiers. Long climbing and descending grades with heavy vehicles are a braking, gradient and stopping-distance proposition rather than a distance proposition, and the concentrations of slow, heavily laden traffic on those sections are exactly the pavement locations where rutting appears first. And the corridors cross large rivers, principally the Zambezi at Caia on the EN1 and again at Tete on the road to the Malawian and Zambian frontiers, which means a small number of structures carry a large share of the traffic. This page states nothing about the condition or availability of any of them.

Axle loads and gross vehicle weights in the region are controlled under national legislation informed by regional harmonisation work within the Southern African Development Community, and enforced at weighbridges along the corridors. No payload figure appears on this page. The legal limit, the tolerance applied in practice and what a specific vehicle and trailer combination may lawfully carry on a specific alignment are matters for the carrier through the forwarder. The correct sequence is to fix the packing and the drum count with the container arithmetic below, then ask the forwarder how that tonnage converts into vehicles on the actual corridor, and to price the handovers as well as the kilometres.

Container detention: the cost line that catches corridor buyers

On a coastal delivery a container is emptied within a short distance of the port and returned. On a corridor delivery, the box goes inland with the cargo and has to come back, and on a haul of a thousand kilometres or more across one or two frontiers the round trip is not measured in days. Shipping lines allow a contractually agreed period of free time and charge detention thereafter; the free period and the charge are commercial terms between the buyer and the line and no figures are stated here. The exposure is real enough that many corridor buyers strip the container at the port or at an inland depot and move drums onward on flatbed vehicles rather than sending the box up-country. That decision has to be made before the cargo is booked, because it changes the packing plan, the handling count and the insurance arrangement. Ask the question at the enquiry stage rather than discovering it on an invoice.

The delivery term has to match the leg, and it has to name a place

Under Incoterms 2020, FAS, FOB, CFR and CIF are rules for sea and inland waterway transport. They are built around a vessel and a port and they have coherent meaning for a parcel discharging at Maputo, Beira or Nacala. They have no coherent meaning for a truck arriving in Lilongwe. The rules that work for any mode are FCA, CPT, CIP, DAP, DPU and DDP, and every one of them names a place.

Four errors recur on Mozambican and corridor business:

• Quoting CIF Beira against an inland project and calling it a delivered price. It is not a delivered price for a buyer in Lilongwe, Lusaka or Ndola; it is a price for the shorter part of the journey. Say so explicitly in the offer, so that the buyer compares like with like.
• Naming a country instead of a place. DAP Mozambique is not a delivery term. DAP followed by a named town, plant or project site is. On a corridor movement the named place must also settle who arranges the formalities at each frontier and who bears the cost of a vehicle standing and waiting, because on a land leg the truck and driver are idle at somebody’s expense.
• Not naming which of the three systems the price is built on. An offer into Mozambique that says only Mozambique is not a comparable offer, because the inland leg it implies can differ by more than a thousand kilometres depending on whether the writer had Maputo, Beira or Nacala in mind.
• Agreeing DDP into a transit destination casually. DDP puts import clearance and charges on the seller. At the far end of a corridor, in a country where the seller has no presence and cannot be the importer of record, that is a much heavier undertaking than it looks on a term sheet.

Packing arithmetic, and then the vehicle

Site standard loading figures, which apply to the sea leg and to any container movement inland, are as follows. New steel drums of 150 kg net give 80 drums and 12 MT per 20 ft FCL. Drums of 180 kg net give 80 drums and 14.4 MT. Drums of 185 kg net give 80 drums and 14.8 MT. Jumbo or poly bags of 1 MT give 20 bags and 20 MT. The 20 ft box is the unit because a cargo of this density reaches its weight limit long before it fills a larger container. Use these figures to fix the drum count, the packing cost per tonne and the number of packages on the transport document; then convert to vehicles with the forwarder, not with a calculator.

Why drums dominate on these corridors

The choice between drums, bags and heated bulk is decided by the inland leg, and on the Beira and Nacala corridors the honest answer is that drums dominate because the leg is long and the receiving end is usually not equipped. The reasons are cumulative rather than a matter of preference:

• Bulk requires heated storage at the destination. A heated road tanker is only useful if the receiver has tankage of adequate capacity, a compatible discharge connection, a pump and the ability to take the whole load promptly. Where a contractor is running a mobile plant on a rural road project a thousand kilometres inland, none of that is present, and no freight quotation changes it.
• A tanker holds temperature badly across a long leg with a frontier on it. Time standing at a border post is time cooling. Reheating a load that has stiffened is an operational problem with a cost and a risk attached, not a delay.
• Bulk sits awkwardly with transit. A movement running under customs supervision to a nominated exit office, against a guarantee, is not a movement in which product can conveniently be split between two receivers or partly discharged en route.
• A drum fails locally. A damaged drum costs one drum out of eighty. A compromised bulk load costs the consignment, at the far end of a corridor, with no realistic reverse gear.
• Drums allow partial delivery and staged call-off. On a project fed at the end of a long corridor, and in a country whose working season is bounded by a wet season, the ability to take material in the quantity the site can use, store the rest under cover and heat it one unit at a time is worth more than the packaging saving.

Where bulk does deserve a hearing on this coast is at Maputo, on a short leg to a permanently equipped installation, and that is the honest boundary. One regulatory line has to be settled before a tanker is booked rather than after: where bitumen is offered for carriage above 100 °C it falls to be classified as UN 3257, elevated temperature liquid, n.o.s., Class 9 under the UN model regulations, and packed bitumen moving at ambient temperature is treated differently. Whether that applies to your movement, and what marking, documentation, equipment and driver qualification follow from it in each country on the route, is a question for the carrier and the forwarder.

Two physical points about drums here

Specify new steel drums and say so in the contract in words. Reconditioned drums are the most common source of contamination disputes in this trade anywhere, and a cargo that changes hands across a port, a depot, a mode change and a frontier gives that argument more places to start. Second, the coastal storage environment is genuinely hostile along the whole 2,500 km: sustained warmth, high humidity and salt-laden air work on drum seams and closures faster than most buyers expect, and in the wet season a stack standing in the open is exposed to rain of an intensity that a temperate warehouse rule was never written for. A consignment that will sit in a port yard while a transit declaration is arranged wants covered storage and a short dwell, not a corner of an open compound.

Where the language actually bites

Mozambique is a member of the Comunidade dos Países de Língua Portuguesa, the community of Portuguese-speaking countries, and unusually it is also a member of the Commonwealth despite having no British colonial history. That combination describes the market well: the institutions and the paperwork are Lusophone, while a great deal of the commercial and engineering traffic through the country is Anglophone. For a bitumen shipment the language appears in five specific places.

• The tender. A Mozambican tender is issued in Portuguese. The tender document is the caderno de encargos, the technical specification is the especificações técnicas and the priced schedule is the mapa de quantidades. The binder clause you must quote against is in that Portuguese text, and it is the clause rather than any translation of it that binds the contract.
• The customs declaration. Declarations are lodged in Portuguese with the customs administration, through the electronic single window operated for that purpose. The goods description that appears there has to correspond to the description on every commercial document, which is a translation problem as well as a consistency problem.
• The commercial set. A buyer will ask for, and a bank may require, a factura comercial, a packing list, a certificado de origem and a certificado de análise. Whether these have to be in Portuguese, bilingual, or accompanied by a certified translation depends on who is receiving them and on the credit terms, and it should be agreed in the contract rather than discovered at presentation.
• The safety data sheet. This is the one where a translation is not a formality. A safety data sheet exists so that the people who handle, store and respond to an incident with the material can read it. A sheet supplied only in English, travelling on a vehicle with a Portuguese-speaking driver to a site with Portuguese-speaking storemen, is failing at its only job. Supply it in Portuguese, and where the cargo is in transit to an Anglophone destination, supply it in both.
• The drum marking. Marking is read by whoever is standing in front of the stack. Where the consignment is for use in Mozambique, marking that a Mozambican storeman can read is worth more than marking that satisfies a file.

The decimal comma, which is the trap nobody warns about

Portuguese, like most continental European conventions, writes decimals with a comma and thousands with a point. A Mozambican or Portuguese-language specification that requires a specific gravity of 1,01 to 1,06 is requiring 1.01 to 1.06 and not one thousand and one. A solubility limit written 99,0 is 99.0 per cent. A penetration written 6,0 in millimetres is 60 dmm.

That sounds too obvious to matter until it is put into a spreadsheet, a compliance matrix or an automated translation, at which point it stops being obvious and starts being a rejected consignment. Three disciplines cost nothing and remove the risk entirely:

• Restate every numeric limit in words on the offer. Where the clause says 1,01 a 1,06, write it out as one point zero one to one point zero six and give the unit and the test method beside it. A number written twice in two forms cannot be misread once.
• Never let a converted number travel alone. If you convert a limit from a Portuguese clause into an English offer, keep the original clause reference beside the converted figure so that the engineer can check the conversion rather than trust it.
• Watch the units as well as the separators. Penetration is properly quoted in decimillimetres, dmm, which is 0.1 mm. Softening point is in degrees Celsius in both languages. Flash point conventions do not change across the boundary, but the number that changes meaning is the one where a comma has been read as a thousands separator.

The terminology trap: betume, asfalto and CAP

Technical vocabulary does not map one to one across this boundary, and the mismatch happens to sit exactly on the product being sold.

• In European Portuguese usage, betume is the binder and asfalto is generally the mixture of binder and aggregate — broadly the same distinction that careful English makes between bitumen and asphalt.
• In Brazilian Portuguese usage the words are used differently, and the binder itself is commonly called asfalto or, in the specification idiom, CAP, for cimento asfáltico de petróleo. Brazilian penetration grades are designated in that idiom — CAP 30/45, CAP 50/70, CAP 85/100 and CAP 150/200 — and they are not the same set of bands as the ASTM grades.
• Technical documents circulate within the Lusophone world, so a Mozambican specification assembled from a Portuguese-language template may carry either idiom. A clause that says asfalto may mean the mix or may mean the binder, and a clause that names a CAP grade is naming a Brazilian designation rather than an ASTM or EN one.

The instruction is short and it should go into the first reply to the enquiry: establish which product the clause is describing and which requirement table the designation belongs to, in writing, before anything is certified. Do not silently translate asfalto as asphalt and assume the tender wants a mix, and do not silently translate a CAP grade into the nearest ASTM one. The cross-reference is a basis for a conversation with the engineer; it is never a defence at delivery.

Other vocabulary worth having on the packing list

A packing list that a Mozambican storeman can check against the stack is a packing list that closes a count argument before it opens. The terms that recur are tambor for drum, peso líquido for net weight and peso bruto for gross weight, lote for batch or lot, ensaio for test, penetração for penetration and ponto de amolecimento for softening point. State net weight with drum tare excluded and say so in both languages, because the difference between net and gross on eighty drums is a quantity dispute waiting to happen.

The corridor problem: the same cargo, two language regimes

A consignment for Malawi, Zambia, Zimbabwe or Eswatini is declared in Portuguese on the Mozambican leg and in English at the destination. That is not a nuisance; it is the most reliable source of the single most common self-inflicted customs problem in this trade, which is a goods description that drifts between documents. A description that is translated slightly differently on the transit declaration than on the import declaration is a description that does not match, and a description that does not match is a hold.

The defence is procedural and it costs nothing. Fix one goods description at contract stage, in both languages, and use it word for word everywhere — on the contract, the credit, the invoice, the packing list, the transport document, the transit declaration, the import declaration and the certificate of analysis. Agree the pair of descriptions with the clearing agents on both sides before the first document is issued, not after the first query. Include the tariff heading with it. Where a bank is involved, get the description into the credit in the exact form the customs administrations will see, because a credit that requires one wording and a customs system that expects another puts the seller in the position of choosing which one to fail.

Whether a translation has to be certified

Whether any document requires a sworn or certified translation, whether it requires legalisation or consular authentication, and in what form, changes over time and by document type. This page states no position on it. Ask the licensed customs broker in the destination country, in writing and dated, which documents must be in Portuguese, which may be bilingual, which require a certified translation and which require any form of authentication — and ask before the documents are issued, because a document that has to be reissued in another form is a document that arrives after the cargo.

Who writes the clause

Road procurement in Mozambique is not run by one body. The classified national network is administered by the national roads administration, the Administração Nacional de Estradas (ANE), with maintenance funded through a dedicated road fund; municipal and provincial authorities run their own urban and local programmes with their own documents; a substantial proportion of trunk and corridor work is financed by development banks and bilateral donors and is designed and supervised by international consultants who bring their own specification traditions; and private industrial and port pavement is designed to whatever standard the client applies. Behind the frontier the same fragmentation repeats in four more countries, each with its own roads authority and its own documents.

The practical result is that a municipal resurfacing package in Maputo, an ANE trunk contract on the EN1, a low-volume sealed road project in Niassa, a donor-financed corridor rehabilitation and a Malawian or Zambian tender at the far end of the same corridor can each carry a different binder clause, a different set of cited test methods and a different view on modified binder. There is no single Mozambican or corridor specification practice to quote against.

The regional documents you will actually meet

Two families of documents explain more about why a southern African binder clause looks the way it does than any single national standard designation would.

• The SATCC standard specifications. The Standard Specifications for Road and Bridge Works issued under the transport and communications arrangements of the Southern African Development Community — commonly still referred to by the older abbreviation SATCC, for the Southern African Transport and Communications Commission — are widely used as the base specification for road works across the SADC states, Mozambique among them. Where a tender in this region does not write its own bituminous clauses from scratch, this is very often the document it is amending.
• South African technical practice. South Africa publishes an extensive and openly cited body of road engineering guidance that is used well beyond its borders: the Technical Recommendations for Highways series, in which the surfacing seal document is the reference behind a great deal of the chip seal work done in this region, and the standardised specifications and technical guidelines issued by the national standards body and by the southern African bitumen industry association. In the southern Mozambican market, where the hinterland is Gauteng and the contractors and consultants frequently are too, a clause written in that idiom is not unusual; it is the default.

The designation problem, which has three separate parts here

This is the section to read twice, because Mozambique is the market where three naming conventions can appear in the same tender file.

• South African practice designates penetration grades in the European band convention, not the ASTM one. The bands ordinarily encountered in South African documents are written in the EN style with a slash, and the specification for penetration grade bitumens is published nationally as SANS 4001-BT1. The consequence for an exporter is direct: a clause originating in that tradition is likely to name a band such as 70/100 or 35/50 rather than an ASTM grade such as 85-100 or 40-50, and the acceptance limits that go with it are the ones in the cited national or European text, not the ones on a Middle East export data sheet.
• ASTM D946 and EN 12591 do not contain the same grades. ASTM D946, the reference behind most Middle East export documentation, names 40-50, 60-70, 85-100, 120-150 and 200-300. EN 12591, the European standard for paving grade bitumens, names bands including 20/30, 30/45, 35/50, 50/70, 70/100, 100/150 and 160/220. There is no ASTM grade 70/100 and no EN band 60/70 or 85/100. A clause and a certificate written in different systems are not describing the same acceptance table even where the numbers look adjacent.
• A Portuguese-language document may carry a Brazilian CAP designation — CAP 30/45, CAP 50/70, CAP 85/100, CAP 150/200 — which is a third system again, and which describes the binder rather than the mix notwithstanding the word asfalto that usually accompanies it.

Working the arithmetic, because the arithmetic is what decides a rejection

The bands are not synonyms and treating them as such is how a cargo gets rejected at the far end of a corridor. Two worked comparisons make the point:

• 70/100 against 85-100. A batch measuring 78 dmm satisfies EN 12591 band 70/100 comfortably and fails ASTM D946 grade 85-100 outright. A batch measuring 90 dmm satisfies both. So an offer of 85-100 against a clause that says 70/100 is offering a narrower window inside the required one, which is safe on penetration but says nothing about whether the flash point, solubility, ductility and ageing limits of the two tables agree. An offer of a 70/100 against a clause that says 85-100 is not safe at all.
• 60/70 against 50/70. Bitumen 60/70 is an ASTM D946 grade with a 10 dmm window. EN 12591 band 50/70 is twice as wide and reaches lower. Every 60/70 batch sits inside 50/70; the converse is false, because a binder correctly supplied as 50/70 may measure anywhere down to 50 dmm and would fail a 60/70 requirement. Read the direction of that argument carefully before offering one against the other.

One notational point saves correspondence: AASHTO M20 writes penetration grades with a hyphen — 40-50, 60-70, 85-100 — while the export trade writes 40/50 and 60/70 with a slash. Those are the same bands measured by the same needle test at 25 °C, and a clause naming grade 60-70 is not naming something different from what an exporter calls 60/70. The slash and the hyphen are a typographical difference; 70/100 against 85-100 is not.

The 80/100 designation, which belongs to no current standard

After 60/70, the grade heard most often in African conversation is 80/100. It is worth being precise about it. ASTM D946 names 85-100 and contains no grade called 80/100. EN 12591 names 70/100 and contains no band called 80/100. The older British standard for bitumens for roads, from which a good deal of anglophone southern African practice descends, named grades in a different style again and has since been withdrawn and superseded by the European standard, so a specification assembled from an old template may cite a document that no longer exists in the form the clause assumes.

So a clause that says 80/100 is telling you the approximate consistency the engineer wants and is not telling you which requirement table the material will be judged against — and the requirement table is where the flash point limit, the solubility limit, the ductility requirement and the ageing criterion actually live. Ask which standard’s table the clause intends, and quote in the same words the tender uses. If the tender says 80/100, do not silently substitute 85-100 or 70/100; state on the offer which specification the material is certified to, print the measured penetration, and get any cross-reference approved by the engineer in writing before dispatch.

Why no Mozambican standard designation appears on this page

Mozambique’s national standards body is the Instituto Nacional de Normalização e Qualidade, commonly abbreviated INNOQ. Its functions are the ordinary functions of a national standards body: developing and publishing Mozambican standards, representing the country in international and regional standardisation work, and carrying the national responsibilities for quality infrastructure that go with that role. At the regional level, standards harmonisation work is carried on within the Southern African Development Community, which is why a tender in this region may cite a designation that is regional rather than purely national.

This page quotes no Mozambican standard designation for paving bitumen, and the reason is the same as on every market page here. Procurement runs through a national roads administration, municipal and provincial authorities, and donor-financed projects designed by international consultants, and their documents are not uniform enough to be reduced to one reference. Designations and editions change. A number quoted from memory into a compliance box on an offer form is a false compliance claim sitting inside a contract, and an invented national standard number is the single worst thing a supplier page can print, because it is precise enough for a buyer to rely on and wrong often enough to ruin a shipment. If an enquiry form asks which Mozambican standard the cargo complies with, the honest answer is that the binding requirement is the one the tender document incorporates, and that you will quote against that clause once you have seen it. Ask for the clause. It is a normal request and a serious buyer will send it.

Five questions to ask about any Mozambican or corridor binder clause

• Which document, which language and which edition? Specifications assembled from older templates carry grades, limits and cited standards that differ from current published texts, and some cite standards that have since been withdrawn. Take the acceptance limits from the text the tender incorporates, in the language it was written in, not from a refinery data sheet and not from memory.
• Penetration, or a performance grade? Penetration is the ordinary case across this region. Where a project is designed and supervised by an international consultant, a performance-graded specification under AASHTO M320 may appear instead, or an MSCR-based grade under AASHTO M332 on heavily loaded pavement, with the traffic adjustment under AASHTO M323 for slow and standing loading. These are different measuring systems and a grade in one cannot be inferred from a grade in another; a penetration certificate cannot evidence a performance grade, and no correlation table changes that.
• Which ageing procedure is controlled? The thin-film oven test (ASTM D1754) and the rolling thin-film oven test (ASTM D2872, AASHTO T240, and in the European system EN 12607-1) are different exposures and their results are not interchangeable. Middle East export certificates carry TFOT by default. If the clause controls RTFOT, add that test to the schedule before the batch is certified, not after the cargo has crossed a frontier.
• Is there a low-temperature requirement, and does the site need one even if the clause omits it? This is the Mozambican corridor question. A Beira, Nacala or Tete project does not need one. A project on the Lichinga or Angónia plateau does, and so does a project on the Zimbabwean, Zambian, Malawian or South African plateau at the far end of the corridor. Fraass breaking point to EN 12593, or a bending beam rheometer requirement under AASHTO M320, has to be agreed in writing because no standard export sheet carries one.
• Are prime and tack coat products in the same package, and is a modified binder required? Cutbacks under ASTM D2027 and emulsions under ASTM D977, ASTM D2397 or in the European framework EN 13808 are separate products with their own acceptance tables, and a paving-grade certificate evidences nothing at all for them. On a network with as much surface dressing in it as this one, they are frequently the larger part of the enquiry.

The band is not a point, and on a corridor that matters twice over

Two cargoes can both be genuine 60/70 and behave differently on a Tete pavement. One measures 61 dmm with a softening point near 56 °C; the other measures 69 dmm with a softening point near 49 °C. Both are in grade and both pass a conformity check against the band. In the Zambezi valley in October they are not the same material. The practical responses, in order of usefulness: require the measured value on a batch-specific Certificate of Analysis rather than a sheet that reprints the specification range; agree a narrower contractual window in writing for the shipment, which leaves the grade name and the tender satisfied while giving you a contractual right to the material you actually need; and read softening point by ring and ball to ASTM D36 as hard as you read penetration, because it is the line that speaks most directly to behaviour at service temperature and it is the line most often skimmed on an export offer.

The corridor adds a second reason to insist on this. A rejected parcel at Beira is a cargo sitting in a port with a shipping document behind it. A rejected parcel that has cleared a frontier, been hauled a thousand kilometres and been discharged at a site on the Zambian plateau is a problem with no realistic reverse gear. The inspection you did not pay for at the loading point is the argument you cannot win afterwards.

Adulteration, solubility and the discipline of the handover

A corridor consignment changes hands more often than almost any other bitumen movement: loading point, vessel, port, depot or mode change, a frontier or two, and a final haul on somebody else’s trucks. Each of those is a place where quantity, condition or composition can be argued about. The technical defence is unglamorous and effective. Solubility in trichloroethylene to ASTM D2042 is the line that shows whether the material is bitumen or bitumen extended with mineral matter; if a certificate omits solubility, treat that as a finding rather than an oversight. Appoint an internationally recognised inspection company to attend loading, sample across the consignment to ASTM D140, and seal retained samples held by both parties. Then carry that discipline into the inland leg: record drum count, drum condition and seal numbers at every handover, because each transhipment is a place where a quantity or condition argument can start, and a recorded count is what closes it before it opens.

What a usable Certificate of Analysis looks like for this market

• Batch or lot identification tying the certificate to the drums actually loaded, not a typical-values sheet reissued for every consignment.
• Penetration at 25 °C and softening point as measured values, each with the ASTM or EN designation printed beside the result, and each read against any narrower contractual window agreed for the shipment.
• Ductility, flash point, solubility, specific gravity and water content, each with its method.
• The ageing result in the form the tender asks for, labelled with the procedure actually run rather than described generically as loss on heating.
• For a plateau site — Lichinga, Angónia, or anywhere beyond the frontier — an agreed low-temperature line, Fraass breaking point to EN 12593 or a bending beam rheometer stiffness and m-value requirement, because no standard export sheet carries one.
• Where a modified binder is supplied, elastic recovery to ASTM D6084, storage stability to ASTM D7173 or EN 13399, and the modification type, not merely the word polymer.
• Nothing about adhesion. Affinity between binder and aggregate cannot be certified from a binder sample alone; it is a mix-level question, tested with the actual project aggregate under EN 12697-11 or as moisture-induced damage on the compacted mix under AASHTO T283. On a wet coast that is the durability question, and any supplier claiming moisture performance on the strength of a binder certificate is overstating what the document can carry.
• Numbers written unambiguously for a Portuguese-language reader: give the value and, where a Portuguese version of the certificate is issued, make sure the decimal separator convention is consistent between the two versions rather than mixed within them.

Who the standards body is

Mozambique’s national standards body is the Instituto Nacional de Normalização e Qualidade, commonly abbreviated INNOQ. Its functions are the ordinary functions of a national standards body: developing and publishing Mozambican standards, representing the country in international and regional standardisation work, and carrying national responsibilities within the quality infrastructure — standardisation, and the metrology, testing and certification arrangements that sit alongside it. Mozambique is a member state of the Southern African Development Community, within which standards harmonisation work is carried on regionally, which is why a tender in this region may cite a designation that is regional rather than purely national. Neither body is a counterparty of ours and nothing in this section describes a relationship with either.

Import conformity assessment, described as a mechanism

Across Africa, national standards bodies commonly administer conformity assessment arrangements for imported goods, and the family most relevant to an exporter is the one generally called pre-export verification of conformity. Programmes of this family exist in several markets under different names, and their common feature is the one that catches exporters out: the verification happens in the country of supply, before the goods are shipped, not on arrival. What follows describes how such a programme is structured. It does not state that any particular arrangement, scope or route is in force in Mozambique, or in any corridor destination, on your shipment date, and it names no appointed inspection body. Those are questions for a licensed customs broker in the destination country to answer in writing and dated.

• The trigger is scope. A programme of this kind applies to a defined list of products, usually expressed by product category and by tariff classification. Whether a given product is inside or outside that list at a given moment is the whole question, and it is the question this page will not answer.
• The applicant is on the supply side. The exporter or the supplier applies to an inspection body appointed to operate the programme for the country or region of supply. The importer usually cannot fix the problem alone from the destination end, which is exactly why it has to be settled at the contract stage rather than after loading.
• There is normally more than one verification route. The common structures are a consignment-by-consignment route based on documentary review of test reports with physical inspection at the loading point and, where required, sampling and laboratory testing; a registration route for a product whose consistency has been established, reducing the work per shipment; and a licensing route for a manufacturer whose quality system has been assessed. Which routes exist, and which is appropriate, is a matter for the appointed body.
• The output is a certificate issued before shipment. A Certificate of Conformity is issued referencing the standard the goods were verified against and the consignment it covers. It travels with the shipping documents and is what customs at the destination expects to see.
• There may also be a marking obligation. Programmes of this kind sometimes sit alongside a mark applied to certain categories of imported goods. Where a mark is required it is a physical marking obligation, which means it has to be established before the goods are packed rather than after.
• The consequence of getting it wrong is not a warning letter. Where a certificate is required and absent, the usual outcomes are detention of the goods, destination inspection and testing at the importer’s cost and time, penalties, or refusal of entry. On this market that penalty lands on a cargo that has already completed an ocean voyage and may be sitting at the sea end of a corridor.

Why this page does not tell you whether bitumen is in scope

Because the scope of these programmes changes. Product lists are amended, tariff lines are added and removed, appointed inspection bodies are re-tendered and replaced, and the available verification routes are revised. An undated page asserting that a product is or is not currently in scope, or naming the body currently appointed for a particular region, is worse than useless: it is a statement precise enough for a buyer to plan a shipment on and wrong often enough to ruin one. So this page names no current scope and no appointed agent.

Put four questions in writing to a licensed customs broker in the destination country before you contract, and put them again if the shipment slips:

• Is this product, under this description and this tariff classification, within the scope of any pre-shipment verification or conformity assessment requirement on my intended shipment date?
• If it is, which verification route applies, which body is appointed for my country of supply, and what does the supplier have to produce and by when?
• Is there a physical marking obligation, and if so, does it have to be applied before the goods are packed?
• What evidence will the customs administration expect at the entry point I am actually using, and does that answer change if the goods are entered for home use rather than moved in transit?

The corridor doubles the question, and this is the point most often missed

If the cargo is destined for Malawi, Zambia, Zimbabwe or Eswatini, then Mozambique’s arrangements are not necessarily the ones that govern, and they may not be the only ones. Each of those countries has its own national standards body, its own customs administration and its own conformity requirements, with their own scopes, their own appointed inspection bodies where they use them, and their own certificate formats. A certificate issued against one country’s programme is not automatically evidence for another’s. The practical rule for a corridor consignment is therefore: ask the clearing agent in the destination country, not only the one in Mozambique, and ask early enough that any pre-shipment verification can actually be arranged in the country of supply. There is no way to fix a missing pre-shipment certificate after the vessel has sailed.

The customs machinery in Mozambique

Customs in Mozambique is administered by the Autoridade Tributária de Moçambique, the national revenue authority, within which the customs administration sits. Declarations are made on the single administrative document, the Documento Único, and trade documentation is channelled through the electronic single window operated for that purpose, the Janela Única Electrónica. Three structural points matter to a seller.

• The file opens before the goods arrive. The importer needs the commercial documents from the seller earlier than a first-time exporter expects, and late or inconsistent seller documentation stops the buyer from opening the file at all.
• The declaration is in Portuguese. The goods description lodged there has to correspond word for word to the description on every other document, which on a corridor movement means it has to correspond to an English description at the far end as well. See the language section above; this is where that discipline is actually tested.
• Classification is a broker question, not a supplier question. Petroleum bitumen falls under HS heading 2713.20. The full national subheading, and any duty, levy, excise or tax treatment, must be confirmed with a licensed customs broker in the destination country. No rates of any kind are stated on this page.

Transit, and the regional arrangement that does not extend the whole way

Where goods landed in Mozambique are destined for Malawi, Zambia, Zimbabwe or Eswatini, the Mozambican leg is a transit movement rather than an import, and a structural point applies that has no equivalent on the East African corridors. Mozambique is a member of the Southern African Development Community. It is not a member of COMESA, the Common Market for Eastern and Southern Africa, whereas Malawi, Zambia and Zimbabwe are members of both. Eswatini and South Africa sit inside the Southern African Customs Union, which Mozambique is also outside.

The consequence is that the regional instruments covering the two halves of a corridor journey are not necessarily from the same family. Regional customs transit guarantee and regional motor insurance instruments developed under one regional grouping apply within that grouping’s membership, and a movement that begins in a SADC-only member state and ends in a state that is in both groupings crosses that boundary. This page states no position on which instrument covers which leg of your movement, because the arrangements evolve and because their application to a specific commodity and route is precisely what a clearing agent is for. What a buyer should take from it is the shape of the question, which is: ask separately about the Mozambican leg and the destination leg, and do not assume that a guarantee, a carnet or an insurance arrangement that covers one covers the other.

The general structure of a transit movement is nonetheless predictable and worth understanding:

• The goods enter Mozambican customs territory without being imported, move under customs supervision to a nominated exit office, and are accounted for there. The importer of record is in the destination country and that country’s revenue authority assesses the goods.
• The movement is covered by a customs guarantee or bond standing in for the charges that would fall due if the goods failed to leave. It has a value, it has a cost, and somebody has to provide it. This is a real cost line that is frequently absent from a first comparison of two offers.
• The movement is controlled, by seals and by whatever monitoring, escort or tracking arrangement applies on the route. A broken or tampered seal is a serious event, not an administrative note.
• The goods cannot be dealt with along the way. A transit consignment is not one that can be split between two receivers, decanted, reblended or partly delivered en route, because the whole procedure rests on the goods that leave being demonstrably the goods that entered. This is one of the strongest practical arguments against a bulk tanker on a transit leg.
• There is a time element and a nominated exit office. The routing is fixed rather than opportunistic, and the guarantee is discharged only when the goods are accounted for at the exit.

One facilitation concept is worth knowing by name because it will come up: the one stop border post, in which the two administrations carry out their controls in a single stop rather than sequentially on each side. Arrangements of this kind have been developed at crossings in the region. Whether any specific crossing on your route operates in that form on your date is a forwarder and clearing agent question and is not stated here.

Insurance: where the cover stops

Two insurance points are specific enough to be worth stating carefully, and both are commonly missed on a first corridor shipment.

First, a marine cargo policy that ends at the port does not cover an inland leg of a thousand kilometres across a frontier. Inland transit cover has to be arranged deliberately and it has to run across the frontier rather than stopping at it. Carrier liability under a road carriage arrangement is limited and is not cargo insurance; it will not make a buyer whole on a full load. Regional motor insurance arrangements that allow a vehicle to cross frontiers are carrier third-party cover and not cargo cover, and they should never be confused with the latter.

Second, the delivery term and the insurance arrangement have to be chosen together rather than in sequence. CIF is the rule under which the seller procures cover; a buyer who intends to place cover at home should be contracting on CFR or FOB instead. Several countries in this region have at various times legislated on where marine cargo cover on imports must be placed. This page states no position on any such requirement, its current form, its exemptions or its application to a particular consignment — confirm all of it with your insurance broker and your clearing agent before the delivery term is agreed, because it is settled in the contract and not afterwards.

Other Mozambican authorities a buyer may encounter

Downstream petroleum activity in Mozambique is regulated by the national energy regulator, and environmental controls on the handling and storage of chemical products sit with the ministry responsible for land and environment. Whether any licensing, permitting or notification obligation attaches to the import, storage or handling of bitumen as a petroleum product, and to whom it attaches, is a question for a Mozambican legal adviser and a licensed customs broker. This page states no position on it, and nothing here is legal, customs, regulatory or compliance advice.

• Bitumen supply to Tanzania — Dar es Salaam is the gateway Beira and Nacala are measured against for Malawi and Zambia, and that page sets out the comparison from the northern side
• Bitumen supply to South Africa — the market behind Maputo, and the source of the penetration band convention a southern Mozambican tender is most likely to be written in
• Bitumen supply to Africa — how the continental picture is organised, and where the southern African corridors sit inside it
• Bitumen supply to Angola — the Atlantic counterpart: another Portuguese-speaking market, another railway corridor into the Copperbelt, and a sharper climate gradient along its own coast
