Bitumen Supply to Senegal: Dakar, Ndayane and the Corridor to Bamako

Senegal occupies the western tip of the African continent, between roughly twelve and seventeen degrees north. Its coast faces the open Atlantic across its whole length, and the Cap-Vert peninsula on which Dakar stands projects further west than any other part of the African mainland; the headland at its end, Pointe des Almadies, is the westernmost point of continental Africa. The country wraps almost entirely around The Gambia, a separate state occupying a narrow strip either side of the Gambia river, so that the southern region of Casamance is nearly detached from the rest of Senegal by a foreign territory. To the north across the Senegal river lies Mauritania; to the east lies Mali; to the south-east and south lie Guinea and Guinea-Bissau.

That geography is not scenery. It produces three commercial facts that a bitumen buyer meets in the first week of an enquiry. The first is that no port on the African mainland lies closer to the Americas, and that Dakar is normally the first West African call on a service arriving from Europe or from across the Atlantic — stated precisely, because the loose version of the claim is wrong: a vessel routing south from northern Europe or from the Mediterranean passes the Moroccan, Saharan and Mauritanian coasts long before it reaches Senegal, so Dakar is not the first African port on that track. It is the first port of this market on it. That is why it has functioned as a relay, bunkering and provisioning point for far longer than modern container shipping has existed, and why a vessel serving a rotation of West African ports frequently starts or ends there rather than in the middle of the coast. The second is that Dakar is the historic ocean head of a corridor running east to Bamako, roughly twelve hundred kilometres inland in a landlocked country whose imports have to arrive through somebody else’s coastline. The third is that Senegal is cut in two by another country, which turns a domestic delivery from Dakar to Ziguinchor into a routing question with a foreign customs territory in the middle of it, or a long detour around it.

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. Freight is therefore a large share of landed cost rather than a rounding error, and on this corridor the inland portion of that freight is not a short final delivery — for every destination beyond the Senegalese frontier it is the majority of the distance. Commonly cited road distances put Thies at roughly 70 km from Dakar, Kaolack at roughly 190 km, Tambacounda at roughly 470 km, the frontier at Kidira at roughly 700 km, Kayes at roughly 800 km and Bamako at roughly 1,200 km. Those figures are given for orientation and an actual routing has to come from a freight forwarder, but the shape of the problem is unmistakable: for a Malian buyer the ocean freight is the smaller half of the transport question and the road haul is the larger half.

The commercial consequence is blunt. A quotation expressed CIF Dakar is a perfectly proper offer, and for a Dakar or Rufisque project it is close to a delivered price. For a project in Bamako or Kayes it prices the part of the journey that is easiest to price and leaves the expensive, frontier-crossing, weighbridge-controlled 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 Senegalese enquiry is not grade or tonnage. It is where the material is actually being used.

The corridor competition, stated at the top because it decides the business

Mali is the only landlocked state behind Dakar, and Dakar does not have it to itself. A Bamako buyer has three ocean gateways that are genuinely in play — Dakar to the west, Abidjan to the south-east and Conakry to the south — with Nouakchott raised periodically as a fourth. What is unusual about this competition, and what a supplier should understand before quoting, is that none of the three wins on sea freight. The ocean leg is a modest and broadly comparable part of the landed cost for all of them. The decision is made on three other things:

• Distance inland. Commonly cited road distances put Bamako at roughly 1,200 km from Dakar and roughly 1,150 km from Abidjan, which is close enough that neither wins outright. Conakry is commonly cited as materially shorter than both, which is why it recurs in Malian freight discussion despite everything else.
• The transit procedure and the guarantee behind it. Senegal, Mali and Cote d’Ivoire are all inside the same West African monetary and economic union, so a Dakar or an Abidjan routing runs from end to end inside one currency and one customs union. A Conakry routing does not. That is a structural difference in paperwork and in exchange exposure, and it is a real one.
• The condition of the road. This is the variable that moves most, it is the one no supplier page can state, and it is the reason a corridor that looked settled last year may not be settled this year. It belongs to a freight forwarder in writing and dated.

A supplier quoting Dakar into Mali should assume from the outset that the offer will be measured against Abidjan and possibly against Conakry, and should build the quotation so that it can be compared at a named inland place rather than at a berth. An offer that cannot be compared that way is not competing; it is only participating.

The standards position, which is what most distinguishes this market from its anglophone neighbours

This deserves stating at the top because it decides how the offer is written, not merely how it is worded. Senegal’s administrative, legal and technical systems descend from the French ones, and its road engineering practice descends from French and European road engineering practice. In concrete terms:

• A paving grade binder is named by an EN 12591 band — 20/30, 30/45, 35/50, 40/60, 50/70, 70/100, 100/150, 160/220, 250/330 — and not by an ASTM D946 grade. The bands and the grades were drawn independently and they are not translations of one another. A buyer offering an ASTM 60/70 against a Senegalese specification is offering something with a different name and a different band.
• Test methods are cited as EN designations, frequently in their French adoptions as NF EN. Penetration is EN 1426, softening point is EN 1427, solubility is EN 12592, resistance to hardening is EN 12607-1.
• The ageing exposure the European system controls is the rolling thin-film oven test, EN 12607-1. Middle East export certificates carry the thin-film oven test, ASTM D1754, by default. They are different exposures and their results are not interchangeable.
• EN 12591 contains no ductility requirement. An export sheet that leads with ductility to ASTM D113 and carries no rolling thin-film oven data is an ASTM document being presented to a European-tradition tender.
• The mix design and durability tradition is French: gyratory compaction, the Duriez test for water sensitivity, wheel tracking at 60 °C, and mix families with names such as BBSG, GB and the high modulus family known as EME. None of those terms appears in an ASTM specification.

None of this makes the material different. It makes the evidence different, and evidence is what a tender accepts or rejects. The single most common technical failure on this market is an offer that is correct on the product and wrong on the paperwork, and the specification section below deals with it at length.

The domestic Senegalese market underneath the corridor traffic

Senegal is a substantial binder consumer in its own right, and its demand is shaped by a road network with an unusual geometry. The dense part of the network sits in the west: the Cap-Vert peninsula and the Dakar conurbation, the corridor to Thies and Touba, the Petite Cote south to Mbour and Saly, and the groundnut basin through Diourbel and Kaolack. From that western concentration, long trunk alignments run out in three directions — north along the Grande Cote and up the Senegal river valley toward Saint-Louis, Podor and Matam; east across the country to Tambacounda and the Malian frontier; and south across or around The Gambia into the Casamance. The result is a network with heavy urban and peri-urban demand at one end and very long, thin, sparsely trafficked legs at the other, and those two halves want different things from a binder and from a packing plan.

Procurement is administered through the roads agency described in the specification section, funded partly through a dedicated road maintenance fund and partly through donor-financed programmes designed and supervised by international consultants, with urban and municipal work adding a further layer. The practical result is the same as in most African markets: there is no single Senegalese specification practice to quote against. An urban resurfacing package, a national trunk road contract and a donor-supervised project can each carry a different binder clause, a different set of cited test methods and a different view on modified binder — though all of them will be written in the European idiom rather than the American one, which is more than can be said for markets a few hundred kilometres to the east.

Two features of Senegalese demand are worth a supplier knowing. The first is the weight of surface dressing and low-volume sealed road work on the rural and regional network, which pulls cutback and emulsion into enquiries far more often than a pure asphalt-concrete market does — and in the European system those products carry their own framework standards and their own designation grammar, which is not the ASTM grammar. The second is the concentration of heavy, slow, channelised traffic on a small number of specific locations: the approaches to the port, the industrial belt around Dakar and Rufisque, the corridor exits toward Thies and Kaolack, and the truck stops and weighbridge approaches on the road east. Those are the places where rutting appears first, and they are a stronger argument for a harder band or for modification than the national climate average is.

The five things that decide a Senegalese or corridor order

• Destination or transit. Is the binder being used in Senegal, or is Senegal the first third of the journey to Kayes or Bamako? This decides the customs procedure, the importer of record, the guarantee, the conformity question and the documents.
• The named delivery place, not the country. Dakar, Saint-Louis, Ziguinchor, Tambacounda, Kayes and Bamako are entirely different propositions, and one of them is on the far side of a third country. An enquiry naming only a country cannot be priced, only guessed at.
• Which specification system the clause is written in, and which band. This is the differentiator on this market, and it is settled in writing before the batch is certified rather than argued about at delivery.
• Which climate zone the site is in. A moderated Atlantic coast, a Sahelian interior and a wet tropical Casamance push the grade in different directions, and the coastal moderation is a real physical effect rather than a rounding error.
• Which conformity regime applies, and whose. Senegal operates a conformity assessment mechanism for imported goods, and so does the destination beyond it. Evidence produced for one is not automatically evidence for another.

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 given as commonly cited approximations for orientation and nothing more. No port draught, channel dimension, berth length, throughput, storage capacity or completion date is stated anywhere on this page, and none should be inferred from any description in it. No transit times, freight rates, vehicle payloads, vessel or tanker capacities, container free time periods, detention charges, duty rates, taxes or levies are stated. No haulier, forwarder, terminal operator, clearing agent, inspection body, railway concessionaire, refinery, product brand or client is named as a counterparty, and no presence, office, agency or shipping history in Senegal, Mali or any other country is claimed. It states no position on whether any product is currently within the scope of any conformity assessment programme, and it names no currently appointed inspection agent, for the reason set out at length in the conformity section. It states no position on the security or accessibility situation on any route in any country: that is a matter for a freight forwarder, a carrier and an insurer, in writing and dated. And it is not legal, customs, regulatory, insurance or compliance advice; a buyer trading across these frontiers must take independent advice covering the goods, the parties, each customs territory on the route and the payment mechanism.

The one fact that explains the port

Dakar stands on the Cap-Vert peninsula, a volcanic promontory projecting west from the Senegalese coast, and the headland at its tip is the westernmost point of the African mainland. The commercial harbour sits on the sheltered eastern side of that peninsula, facing the bay rather than the open Atlantic, with the peninsula itself standing between the harbour and the ocean swell. This is a genuinely unusual configuration on a coast that is otherwise long, straight, surf-beaten and short of natural shelter, and it is the reason a port grew here rather than somewhere more central.

Two commercial consequences follow, and they are the reason this page opens with geography rather than with product.

• No port on the African mainland lies closer to the Americas, and Dakar is normally the first West African call on a service arriving from Europe or from across the Atlantic. That has to be said precisely, because the loose version of it is simply wrong. A vessel routing south from northern Europe or out of the Mediterranean passes the Moroccan, Saharan and Mauritanian coasts long before it reaches Senegal, so Dakar is not the first African port on that track and no page should tell you it is. What it is, is the first port of the West African market on that track, and the nearest point of the African mainland to the Americas across the narrowest part of the Atlantic. That is what has made the port a relay, bunkering and provisioning call throughout the modern history of Atlantic shipping, long before containerisation, and it is the structural reason Dakar has a maritime function out of proportion to the size of its national market.
• It is therefore a natural transhipment point. Where a service does not call directly at a smaller West African port, cargo may be worked through a larger one and relayed onward on a feeder. Dakar’s position at the corner of the continent makes it a candidate for that role in a way that a port in the middle of the Gulf of Guinea is not. For a bitumen buyer this matters in one specific and practical way: a transhipped container is handled more times than a direct one, and every extra lift is a place where a drum is dented, a pallet shifts, a seal is broken and a count is disputed. If your routing involves a relay, say so in the packing specification and price the handling accordingly. This page states nothing about which services call where or which routings transship; that is a forwarder question in writing.

The inference a Senegalese enquiry most often makes wrongly is from the presence of a petroleum sector. Dakar has one, and buyers therefore assume a bitumen parcel can be discharged in bulk, heated and drawn off. 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 port name, from the presence of an oil terminal, or from the fact that a port is important. A facility engineered for crude and refined fuels that flow at ambient temperature tells you nothing about whether a bitumen parcel can be discharged, heated, stored and released there. 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 Senegalese facility handles bitumen, and no facility named here is a counterparty of ours.

Ndayane, described carefully and no further

A deep-water port facility has been developed on the coast south of Dakar in the Ndayane area, at the northern end of the Petite Cote shoreline that runs on south past Popenguine and Somone toward Saly and Mbour. The logic of a development of that kind is the same wherever it appears: a historic port grows inside a city, the city grows around it, land for expansion runs out, road access becomes the constraint rather than the water, and a greenfield site away from the urban core offers room that the old site cannot. Several West African states have pursued the same idea for the same reason.

This page states nothing about its operating status, its capacity, its draught, its berths, its equipment, what cargo it handles, or when any phase of it was or will be completed. That refusal is deliberate and it is the single most useful thing this section can do for a buyer. Facts of that kind change, they are frequently reported inconsistently, and an undated web page asserting one is precise enough for a buyer to plan a shipment on and wrong often enough to ruin one.

What is worth a planner’s attention is structural rather than operational, and it is stable enough to state. A facility located away from the peninsula sits at a different road distance from a Dakar-area project and avoids a different set of urban approaches, so the final delivery leg for a peninsula site and for a Petite Cote site is not the same from both locations. And it changes nothing whatever about the corridor: the twelve hundred kilometres to Bamako begin wherever the cargo lands, and they are the same twelve hundred kilometres. Ask the forwarder, in writing and dated, which facility your cargo would actually be worked at, and build the inland plan from that answer rather than from an assumption.

The railway, and the honest thing to say about it

Senegal is connected to Bamako by a railway alignment as well as by a road. The line was built by the colonial administration under a name that explains the whole logic of the corridor — the Dakar to Niger railway — because the intention from the beginning was to reach the Niger river basin, and the corridor described on this page is that intention in its modern form. It runs east from Dakar through Thies, Diourbel, Guinguineo, Tambacounda and Kidira, crosses into Mali and continues through Kayes and Kita to Bamako. It is metre gauge, 1,000 mm, the same gauge as the Abidjan alignment, so there is no break of gauge to design around on either western corridor.

The honest statement about it is short. The line has been built and it has been interrupted for long periods. This page asserts nothing about whether any section is operating, whether any service runs, whether any part of it is available for this commodity in your packing on your date, or what any rehabilitation programme has or has not achieved. Those are operating matters, they change, and they belong to a freight forwarder in writing. What a planner should take away is that the road is the realistic default planning assumption for a Malian corridor consignment and that any rail element is something to be confirmed rather than assumed. A shipment plan that depends on a rail movement should be checked before the cargo is booked, not after.

The Gambia in the middle, and what it does to a domestic delivery

No other market on this site has this feature and it deserves its own paragraph. The Gambia is a separate sovereign state occupying a narrow strip either side of the Gambia river, and it runs from the Atlantic coast eastward across Senegal for a substantial distance, leaving the Casamance region of Senegal nearly severed from the rest of the country. A road movement from Dakar to Ziguinchor that takes the direct alignment goes south from Kaolack, crosses the Gambia river in the Farafenni and Soma area — where a road bridge replaced the historic ferry crossing — and continues south into the Casamance. In doing so it enters and leaves a third customs territory on what the invoice describes as a domestic Senegalese delivery.

The alternative is the eastern detour: east to Tambacounda and then south and west through Velingara, Kolda and Sedhiou, which stays inside Senegal throughout at the cost of a great deal of distance. Neither routing is obviously right. The point for a supplier is narrower and more useful than a recommendation: a Casamance delivery has two very different cost structures behind it, and an offer that has not established which one applies is not a firm offer. Whether the direct crossing is available to commercial freight of this description on your date, what formalities apply and what they cost is a question for a licensed clearing agent and a forwarder in writing, and nothing on this page asserts any of it.

The road east, the weighbridges and the freight-sharing arrangement

The trunk road east from Dakar through Thies, Kaffrine and Tambacounda to Kidira, and on across the frontier through Kayes and Kita to Bamako, is the spine of the corridor. Three operational facts shape a consignment on it.

• Axle loads are regulated regionally, not just nationally. The West African Economic and Monetary Union adopted a regulation in 2005 harmonising the control of vehicle dimensions, gross weight and axle load on inter-state roads across its member states, and it is enforced at weighbridges along the corridor. 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. Fix the packing and the drum count using the container arithmetic below, then ask the forwarder how that tonnage converts into vehicles.
• Who carries the freight may not be a free choice. Bilateral arrangements between coastal states and their landlocked neighbours in West Africa have long allocated shares of corridor freight between the carriers of the two countries, commonly described as a two-thirds share to the landlocked state’s hauliers and a one-third share to the coastal state’s, with allocation channelled through freight bureaux and loading stations rather than negotiated truck by truck. Whether such an arrangement applies to your movement in its historic form, and what it does to price and to scheduling, is a question for a forwarder who works this axis. It is raised because it is a feature of West African corridors with no analogue on most routes described elsewhere on this site, and a buyer who assumes they can simply appoint a haulier of their choosing may find the process is more structured than that.
• Checkpoints and stopping time are a documented feature of the region’s corridors. The regional bodies established an observatory to monitor checkpoints, stopping time and informal payments on the main West African axes, and it has published periodic reports. No figures from it are reproduced here and none should be inferred. The reason to mention it is practical: the phenomenon is measured and discussed openly, so a forwarder quoting the axis can be asked directly what stopping time they build into a schedule, and a buyer should ask.

Container detention: the cost line that catches corridor buyers

This is the point most often missed on a first inland shipment. On a Dakar-area delivery a container is emptied within a short distance of the port and returned. On a Bamako delivery, the box goes inland with the cargo and has to come back, and on a haul of twelve hundred kilometres across a frontier 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 in the Dakar area or at an inland facility 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, has to name a place, and here it also has a French name

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 in Senegal. They have no coherent meaning for a truck arriving in Bamako or in Kayes. The rules that work for any mode are FCA, CPT, CIP, DAP, DPU and DDP, and every one of them names a place.

Because contracts on this market are frequently drafted in French, it is worth knowing that the rules have official French names and that a French-language contract will use them. FCA is Franco Transporteur; CPT is Port Paye Jusqu’a; CIP is Port Paye, Assurance Comprise, Jusqu’a; DAP is Rendu au Lieu de Destination; DPU is Rendu au Lieu de Dechargement; DDP is Rendu Droits Acquittes; FOB is Franco a Bord; CFR is Cout et Fret; CIF is Cout, Assurance et Fret; FAS is Franco le Long du Navire; and EXW is A l’Usine. These are the same rules, not different ones, but a buyer reading a French contract and a seller reading an English one must be satisfied they have agreed the same rule and the same named place, and the safest drafting names the three-letter code as well as the words.

Four errors recur on Senegalese and corridor business:

• Quoting CIF Dakar against a Malian project and calling it a delivered price. It is not a delivered price for a buyer in Kayes or Bamako; it is a price for the shorter and cheaper part of the journey. Say so explicitly in the offer, so that the buyer compares like with like against an Abidjan or Conakry alternative.
• Naming a country instead of a place. DAP Senegal 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 the 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.
• Agreeing DDP into Mali 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.
• Treating a Casamance delivery as an ordinary domestic leg. If the routing crosses The Gambia, the named place and the risk transfer point sit on the far side of formalities in a third country. Settle in the contract who deals with that and who carries the delay.

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.

Bulk against drums on a twelve hundred kilometre corridor

The choice is decided by the inland leg, and the honest answer is that drums dominate on the Bamako leg, because the corridor 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 road project in western Mali or in the Senegalese interior, 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 seal to a nominated destination office against a guarantee is not one in which product can conveniently be split between two receivers or partly discharged en route. That constraint is structural, not administrative.
• A drum fails locally. A damaged drum costs one drum out of eighty. A compromised bulk load costs the consignment, twelve hundred kilometres inland, 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 working to a season bounded by a short intense rainy period, 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 make sense in this market is on the Cap-Vert peninsula and the Petite Cote, and at large fixed installations with permanent tankage. That is the honest boundary: a short leg to an equipped plant argues for bulk; a corridor haul to a mobile plant argues for drums, and nothing in between changes that logic. 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.

Three physical points about drums on this particular corridor

First, specify new steel drums and say so in the contract, in words rather than by implication. Reconditioned drums are the most common source of contamination disputes in this trade anywhere, and a cargo that may be relayed at sea, handled at a port, stripped at a yard, crossed over a frontier and delivered to a site gives that argument five places to start.

Second, the Senegalese storage environment attacks packaging in two different ways at two different times of year, and a specification written for one is not adequate for the other. On the coast the enemy is salt-laden air and high humidity, which work on drum seams, closures and printed markings faster than most buyers expect. In the interior during the dry season the enemy is dust: the Harmattan carries fine material that works into closures, degrades markings and contaminates anything opened in the open air. Covered storage answers both; an open compound answers neither.

Third, the rainy season here is short and intense rather than long and steady, and that changes the risk. Drums are filled hot and the block shrinks as it cools, leaving a shallow depression in the top head. In a heavy storm that depression collects water, and a drum with water sitting on the block that is charged into a melter produces violent foaming and boil-over when the water flashes to steam under a layer of hot bitumen. That is a safety point, not a quality point, and a market with a short violent wet season is more exposed to it than a market with a long drizzle, because the water arrives faster than a yard reacts.

Two traditions, drawn independently

Road engineering divides, roughly, into two documentary traditions. One descends from American practice and expresses itself in ASTM and AASHTO designations: penetration grades named 40-50, 60-70 and 85-100 under ASTM D946, ageing controlled by the thin-film oven test under ASTM D1754, ductility measured under ASTM D113, solubility measured in trichloroethylene under ASTM D2042. The other descends from European and, in West Africa, specifically French practice, and expresses itself in EN designations: paving grade bands named 35/50, 50/70 and 70/100 under EN 12591, penetration measured under EN 1426, softening point under EN 1427, resistance to hardening controlled by the rolling thin-film oven test under EN 12607-1, solubility measured in toluene under EN 12592.

Senegal is firmly in the second tradition, and so are Mali, Cote d’Ivoire, Burkina Faso, Niger, Togo and Benin. Ghana and Nigeria, further east along the coast, lean to the first. That is why this page treats the standards position as a genuine differentiator rather than a footnote: a supplier who has shipped into Tema or Lagos on ASTM paperwork has not thereby learned how to ship into Dakar, and a buyer comparing a Dakar corridor with a Gulf of Guinea corridor may be comparing two documentary regimes as well as two roads.

Stated at its bluntest, and this is the sentence to carry away from the page: a buyer offering an ASTM 60/70 against a Senegalese specification is offering something with a different name and a different band. Not a different quality, not a worse product — a different name and a different band, judged against a different requirement table.

What the two systems actually are, and where they diverge

The divergences that cost money are these, in order of how often they bite:

• The grade bands are not translations. EN 12591 names nine bands — 20/30, 30/45, 35/50, 40/60, 50/70, 70/100, 100/150, 160/220 and 250/330 — and ASTM D946 names five grades — 40-50, 60-70, 85-100, 120-150 and 200-300. There is no one-to-one mapping. The EN bands are generally wider and reach lower than the ASTM grade nearest them, and two of the EN bands correspond to no ASTM grade at all. The designations table below sets the arithmetic out band by band, because this is where the argument is won or lost.
• The ageing exposure is different. ASTM D946 controls hardening by the thin-film oven test, ASTM D1754, and expresses the result as a minimum retained penetration. EN 12591 controls hardening by the rolling thin-film oven test, EN 12607-1, and expresses the result through three separate lines: change of mass, retained penetration, and the increase in softening point after hardening. The rolling thin-film oven and the thin-film oven are different exposures and their results are not interchangeable. The increase-in-softening-point line has no ASTM D946 analogue at all, so it is not a line an ASTM export certificate can be read to satisfy — it is a line that has simply not been measured.
• EN 12591 has no ductility requirement. Ductility is an ASTM-tradition property. The European system, where it wants a measure of that family, uses force ductility under EN 13589 and cohesion by pendulum under EN 13588, and applies them mainly to modified binders. So a certificate that leads with a ductility figure of 100 cm minimum, carries a thin-film oven loss on heating line and reports solubility in trichloroethylene is an ASTM document. It may describe an entirely sound binder. It does not answer an EN 12591 clause.
• EN 12591 carries properties ASTM does not. Fraass breaking point under EN 12593 and wax content under EN 12606-1 are properties the European standard permits a purchaser or a national annex to require, and neither has an ASTM D946 equivalent. Wax content in particular is a European preoccupation with no American counterpart, and if a clause asks for it the test has to be scheduled before the batch is certified.
• The solvent differs. Solubility under EN 12592 is determined in toluene; under ASTM D2042 it is determined in trichloroethylene. The property being measured is the same in substance — whether the material is bitumen or bitumen extended with mineral matter — but the documents are different and the certificate should print the designation actually run.
• The flash point convention differs. Both systems require a Cleveland open cup flash point, under EN ISO 2592 and ASTM D92 respectively. The minima are not the same figure, they are set band by band or grade by grade in the respective standards, and neither of them is the 250 °C that export data sheets commonly publish. ASTM D946 sets a minimum of 232 °C for its grades; EN 12591 sets its own minima, higher for the harder bands than for the softer ones. Take the acceptance limit from the standard the tender cites, not from a data sheet and not from memory.

The bodies to know, described by what they do

Four Senegalese institutions are worth a buyer being able to name, and they are named here as public bodies rather than as counterparties. None of them is a counterparty of ours and no relationship with any of them is claimed or implied.

• The national standardisation body is the Association Senegalaise de Normalisation, ASN. Its functions are the ordinary functions of a national standards body: developing and publishing national standards, representing the country in regional and international standardisation work, and carrying responsibilities in relation to conformity assessment for goods placed on the market. It is the body a tender means when it refers to a national standard. This page quotes no Senegalese national standard designation for paving bitumen, for the reason set out below.
• The roads agency is AGEROUTE Senegal, which acts as the delegated contracting authority for road works on behalf of the state. In practice that means it is the body whose tender documents most Senegalese binder clauses come out of, and a supplier asking for the binder clause is asking for a document that this agency or its supervising consultant has drafted. It is described here by function; nothing on this page states its current scope, structure, budget or programme.
• A dedicated autonomous road maintenance fund channels resources to the maintenance programme separately from capital works. That structure is the reason maintenance packages and construction packages can carry different technical documents, different cited methods and different views on modified binder, and it is why there is no single national clause to quote against.
• A national public works research and testing laboratory carries out geotechnical and materials testing for public works. It matters to an exporter because it is the sort of body that may be asked to verify a binder at destination, and a destination test run to EN methods against a certificate written to ASTM methods is precisely the mismatch this section exists to prevent.

Why no national standard number appears on this page. Procurement runs through a national roads agency, a maintenance fund, municipal and regional authorities and donor-financed projects designed by international consultants, and their documents are not uniform enough to be reduced to one reference. 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 designation 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 Senegalese 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.

Where the design thinking comes from, and why it explains the clause

The design reasoning behind francophone West African road specifications is traceable to two lineages, and knowing them explains more about why a clause looks the way it does than any standard number would. The first is metropolitan French practice, the guidance developed by the French central public works laboratory and the roads directorate, which is where the mix families, the gyratory compaction approach and the performance-based mix design tradition come from. The second is the tropical adaptation of it: a practical pavement design guide for tropical countries, developed in the French cooperation tradition and widely used across francophone Africa, which stands in the same relation to these markets as the British tropical road notes stand to East Africa. A tender in Dakar, Tambacounda or Bamako is very often a local application of that lineage, and it will look unfamiliar to an engineer trained only on American documents.

The practical expressions to recognise:

• Mix families with French names. A tender may specify a semi-coarse asphalt concrete for a wearing course, a bitumen-bound gravel for a base course, a very thin asphalt concrete for a surfacing, or the high modulus family known as EME. These are not loose descriptions; they are defined mix types with defined performance requirements.
• High modulus asphalt changes the binder question entirely. The high modulus family is built on a very hard binder, and hard paving grade bitumens sit in their own European standard, EN 13924-1, at grades such as 10/20 and 15/25. ASTM D946 names nothing in that range at all. If a Senegalese tender specifies a high modulus base or binder course — and on a heavily loaded urban or port approach it may — check the binder grade before assuming it is a paving grade, because it may not be a grade your certificate has a table for.
• Water sensitivity is measured differently. The American tradition tests moisture-induced damage on the compacted mix under AASHTO T283. The French tradition uses the Duriez test, which compares the compressive strength of immersed specimens against dry ones and expresses the result as a ratio. In the harmonised European system, water sensitivity of bituminous mixtures is covered by EN 12697-12, which includes both an indirect tensile strength ratio route and a compressive route derived from the Duriez tradition. On a market whose governing durability problem in the Casamance is moisture, this is the test that matters most — and it is a mix-level test with the project aggregate, not something a binder certificate can evidence.
• Rutting is measured with a wheel tracker. The French tradition assesses rutting resistance with a laboratory wheel-tracking test at 60 °C, covered in the European system by EN 12697-22, with a rut depth limit expressed as a percentage after a stated number of cycles. Again, a mix-level test.
• Affinity between binder and aggregate is assessed under EN 12697-11. Nothing in a binder certificate evidences it, and any supplier claiming moisture performance on the strength of a binder certificate is overstating what the document can carry.

Modified binders, emulsions and cutbacks: the designation grammar is different too

This trips up exporters more often than the paving grades do, because the European system for these products is not a list of named products but a framework of classes.

• Polymer modified bitumen falls under EN 14023, which is a framework specification: it defines properties and a set of numbered classes for each, and the purchaser or the national annex selects which classes apply. There is therefore no such thing as a complete clause that says only PMB to EN 14023. A clause in that form is incomplete, and the correct response is to ask which classes are required for penetration, softening point, elastic recovery under EN 13398, storage stability under EN 13399, and cohesion or force ductility. The ASTM-tradition equivalents — elastic recovery under ASTM D6084 and storage stability under ASTM D7173 — are different documents measuring related things, and a certificate carrying one does not satisfy a clause citing the other.
• Cationic bituminous emulsions fall under EN 13808, and the designation grammar is genuinely unfamiliar to an ASTM-trained reader. A European emulsion designation looks like C60B4: the leading letter indicates a cationic emulsion, the number is the nominal binder content as a percentage, the following letter indicates the type of base binder, and the next figure is the breaking behaviour class, with further letters for the intended application. That is a different system from the ASTM one, which names products RS, MS, SS and CRS, CMS, CSS under ASTM D977 for anionic and ASTM D2397 for cationic emulsions. A tender asking for a C60B4-type designation is not asking for something an ASTM emulsion certificate describes.
• Cutback and fluxed bituminous binders fall under EN 15322 in the European system, against ASTM D2027 for medium-curing cutbacks in the American one. On a market where a substantial part of the rural network is surface dressed and where every square metre of new granular base wants a prime coat, this is not an exotic corner of the catalogue; it is a routine part of a Senegalese enquiry.

One European mechanism that causes confusion, and how to handle it

EN 12591, EN 14023 and EN 13808 are harmonised European standards, and material placed on the market inside the European Union under a harmonised standard carries a CE marking and a declaration of performance under the European construction products regime. That mechanism is a rule about placing goods on the European market. A clause in a West African tender that has been assembled from a European template may nonetheless ask for it, and an exporter supplying from outside the European Union cannot produce it in the ordinary way. The correct handling is not to ignore the line and it is not to invent a document. It is to raise the question with the engineer in writing before the offer is submitted: state that the material is tested and certified against the requirement table of the cited standard by the stated test methods, produce the batch data, and ask whether that satisfies the clause or whether a different form of evidence is required. This is a normal conversation and engineers have it regularly. What is not survivable is discovering the requirement at the letter of credit stage.

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

Two cargoes can both be genuine 50/70 and behave differently on a Senegalese pavement. One measures 52 dmm with a softening point near the top of the range; the other measures 68 dmm with a softening point near the bottom. Both are in band and both pass a conformity check. On a heavily loaded Dakar port approach, or on a Bamako intersection, 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 band; agree a narrower contractual window in writing for the shipment, which leaves the band name and the tender satisfied while giving you a contractual right to the material you actually need; and read softening point by EN 1427 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. A rejected parcel at Dakar is a cargo sitting in a port with a shipping document behind it. A rejected parcel that has cleared a frontier, been hauled twelve hundred kilometres and been discharged at a site in Mali 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, and a Dakar consignment may add a relay to the list: loading point, vessel, possible transhipment, port, stripping yard or mode change, a frontier, and a final haul on somebody else’s trucks. Each of those is a place where quantity, condition or composition can be argued about, and the Malian case is the one where the argument is hardest to win, because it usually starts a thousand kilometres past the last place either party was standing. The technical defence is unglamorous and effective. Solubility is the line that shows whether the material is bitumen or bitumen extended with mineral matter; on this market ask for it under EN 12592 rather than assuming an ASTM D2042 line satisfies the clause, and if a certificate omits solubility altogether 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 or its European equivalent EN 58, 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 a recorded count is what closes a quantity argument before it opens.

Five questions to ask about any Senegalese or Malian binder clause

• Which standard’s table, and which edition? An EN band and an ASTM grade are not two names for one thing. Establish which document the clause incorporates, because the flash point minimum, the solubility limit, the ageing criterion and the whole property list live in that table rather than in the grade name.
• Which ageing procedure is controlled? If the clause cites EN 12607-1, a thin-film oven result does not answer it, and the increase in softening point after hardening is a line that has to be measured rather than inferred. Add the test to the schedule before the batch is certified, not after the cargo has sailed.
• Are the optional EN properties invoked? Fraass breaking point under EN 12593 and wax content under EN 12606-1 are properties EN 12591 permits and ASTM does not carry. If they are in the clause they have to be tested, whether or not the climate justifies them — and on this geography the Fraass line is a contractual requirement rather than a climatic one.
• Is this a paving grade at all? If the tender specifies a high modulus mix, the binder may be a hard paving grade under EN 13924-1 rather than an EN 12591 band, and that is a different product with a different table.
• Are prime coat, tack coat and surfacing products in the same package? Emulsions under EN 13808 and cutbacks under EN 15322 are separate products with their own designation grammar and their own acceptance tables, and a paving-grade certificate evidences nothing at all for them.

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 EN designation printed beside the result where the tender is written in the European idiom, and each read against any narrower contractual window agreed for the shipment.
• The full EN 12607-1 hardening set where the clause requires it: change of mass, retained penetration and increase in softening point, labelled as rolling thin-film oven results rather than described generically as loss on heating.
• Solubility with the solvent and the designation stated, flash point with the method stated, and density reported in the European convention rather than as a dimensionless specific gravity if the clause is written that way.
• Any optional EN property the clause invokes, tested and reported, rather than omitted with a note that it is not normally measured.
• Where a modified binder is supplied, the EN 14023 class numbers actually met, with elastic recovery and storage stability results — not merely the word polymer.
• Nothing about adhesion or water sensitivity. Those are mix-level questions answered with the project aggregate under EN 12697-11 and EN 12697-12 or by the Duriez test, and no binder certificate can carry them. On a Casamance project that is the governing durability question, so it has to be commissioned rather than assumed.

Who the standards body is

Senegal’s national standardisation body is the Association Senegalaise de Normalisation, ASN. Its functions are the ordinary functions of a national standards body: developing and publishing national standards, representing the country in regional and international standardisation work, and carrying responsibilities in relation to conformity assessment for goods placed on the market. At the regional level Senegal sits inside two overlapping structures — the West African Economic and Monetary Union, which operates a customs union with a common external tariff and a shared currency, and the wider Economic Community of West African States — and both have standardisation and trade-facilitation programmes whose instruments a tender or a customs file may reference. Neither those bodies nor ASN is a counterparty of ours and nothing in this section describes a relationship with any of them.

The conformity mechanism, described as a mechanism

Senegal, like most of its neighbours, has operated a conformity assessment arrangement for imported goods of the family generally called verification of conformity to standards. Programmes of this family exist across West Africa under different national 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 on your shipment date — that is for a licensed customs clearing agent in the destination country to confirm in writing.

• The trigger is scope. The programme applies to a defined list of products, usually expressed by product category and 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 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.
• The referenced standard matters more here than on an anglophone market. This is the francophone refinement of a mechanism that exists everywhere. A verification programme verifies against a named standard, and in a market working in the European tradition that standard is likely to be an EN designation. Test reports produced against ASTM methods may not answer it. Establish which standard the verification will run against at the same moment you establish whether verification applies at all.
• 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 ocean end of a twelve hundred kilometre 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, the 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 clearing agent 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 the verification programme 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 when?
• Against which standard will the verification be carried out, and in which system’s test methods must the supporting test reports be written?
• What evidence will the customs authority 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 Mali, then Senegal’s programme is not necessarily the one that governs, and it may not be the only one. Mali has its own national standards body and its own arrangements for imported goods, with its own scope, its own appointed inspection bodies and its own certificate format. A Certificate of Conformity 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 Senegal, 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 cargo tracking note, which is a West African speciality

One documentary requirement recurs across this region and has no counterpart on most of the other markets on this site, so it is worth describing as a mechanism. Several West African destinations have at various times required an electronic cargo tracking note — in French a bordereau de suivi des cargaisons — for inbound cargo. Whether any such requirement is in force for your commodity on your route on your date is not stated here. The mechanism is consistent wherever it appears: it is a document of the destination, obtained at the origin, before or shortly after the vessel sails, referencing the bill of lading, the invoice and the freight details, and administered by or on behalf of the destination country’s shippers’ council. Senegal has a national shippers’ council, the Conseil Senegalais des Chargeurs, and Mali has its own equivalent body for Malian cargo.

Two features make it dangerous. The first is timing: in the ordinary case it cannot be obtained after the fact, or can only be obtained at a penalty, so a shipment that sails without it has a problem that cannot be corrected at the destination. The second is that on a corridor movement it may be the destination country’s note that is required rather than the coastal country’s, or both. Whether the requirement applies to your commodity, on your route, on your date, and who has to obtain it, is a question for a licensed clearing agent in the destination country. This page states no position on current scope or current administration, and names no issuing body or agent as a counterparty.

Customs, the tariff and the currency

Customs in Senegal is administered by the national customs administration, and the country has long worked with electronic lodgement of declarations and a national single window for external trade formalities. What that machinery requires of your file on your date is a question for a licensed clearing agent and is not stated here. Two structural points matter to a seller. The first is that the import file is opened before the goods arrive, which means 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 second is that Senegal sits inside a customs union operating a common external tariff, so the classification question has a regional as well as a national layer to it.

Petroleum bitumen falls under HS heading 2713.20. The full national subheading, and any duty, levy or tax treatment, must be confirmed with a licensed customs clearing agent in the destination country. No rates of any kind are stated on this page.

One commercial feature of this corridor differentiates it genuinely and almost no supplier page mentions it. Senegal, Mali, Cote d’Ivoire, Burkina Faso, Niger, Togo, Benin and Guinea-Bissau share a single currency, the West African CFA franc, issued by a common central bank. A Dakar corridor to Kayes or Bamako therefore runs from end to end inside one currency and one customs union, and so does an Abidjan corridor to the same destination. A Conakry corridor does not: it crosses a currency boundary and a customs union boundary. That does not by itself make one route better than another — the Conakry route has the shortest road distance to Bamako, which is a real advantage — but it is a structural difference in the inland leg that a Malian buyer weighs, and a seller quoting Dakar should understand why it comes up.

Transit under the regional road transit arrangements

Where goods landed at Dakar are destined for Mali, the movement is a transit rather than an import, and the region has a long-established instrument for it: the inter-state road transit convention adopted by the regional bodies, under which goods move under customs seal from the coastal port to a customs office in the destination country under a single document backed by a guarantee, with a chain of national guarantors, conventionally the chambers of commerce. The structural consequences are worth understanding even though the detail belongs to a clearing agent.

• The goods are assessed by the destination country’s customs administration, not by Senegal, and the importer of record is in the destination country. The Senegalese leg is a movement, not an import.
• The movement is covered by a customs guarantee standing in for the charges that would fall due if the goods failed to leave, and somebody has to provide it. It has a value and it has a cost. Ask explicitly whether the movement is running on one guarantee end to end or on successive national guarantees, because the ideal of a single instrument has not always been fully implemented in practice on every axis, and the difference is a real cost and a real administrative burden.
• The goods cannot be dealt with along the way. A sealed movement running to a nominated destination office is not one that can be conveniently 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, and it is also why an order destined partly for Senegal and partly for Mali has to be planned as two consignments rather than one.
• There is a time element and a destination office. The routing is fixed rather than opportunistic, and the guarantee is discharged only when the goods are accounted for at the nominated office. Some axes at some periods have also used customs escort or convoy arrangements, which affect scheduling; whether any apply to your movement is a forwarder and clearing agent question.

Two further points shape the frontier experience. Regional third-party motor insurance for vehicles crossing frontiers in West Africa has long been provided through the ECOWAS Brown Card scheme, which is a carrier’s arrangement rather than cargo cover and should never be confused with cargo insurance; whether it governs your carrier’s vehicles on your route is a question for the carrier and the forwarder. And one caution has to be stated plainly rather than glossed over: the institutional arrangements governing this region have been changing. Membership of the regional political and economic bodies, and therefore the instruments under which a transit movement runs, is not a fixed background fact that a supplier page can assert once and leave standing. Which convention governs your movement, which guarantee chain applies, and what the tariff treatment is at each frontier are questions for a licensed customs clearing agent in the destination country, answered in writing and dated, and re-asked if the shipment slips. This page states no position on the current membership or status of any body or any state.

The Gambia: a third customs territory inside a domestic delivery

This point has no analogue anywhere else on this site and it is worth its own heading. A movement from Dakar to the Casamance by the direct alignment crosses into and out of The Gambia, a separate sovereign state with its own customs administration, its own currency and its own procedures — and it is not a member of the West African monetary union whose currency and customs union cover the Malian corridor. So a delivery that is domestic in Senegalese commercial terms is, in transport and customs terms, a transit through a foreign territory with its own formalities.

The practical consequences are the ones a first-time seller does not anticipate. There is a formality event in the middle of a national delivery, and somebody has to be responsible for it in the contract. There is a delay exposure on that crossing that is not under the control of either party. And the alternative — the long eastern detour through Tambacounda, Velingara and Kolda — is a completely different cost structure rather than a marginal variation. Establish at the enquiry stage which routing the offer is built on, name it in the offer, and settle in the contract who handles the crossing formalities and who bears the cost of a vehicle standing and waiting. Whether the crossing is available to commercial freight of this description on your date, and what procedure governs it, is a question for a licensed clearing agent and a forwarder in writing. This page asserts nothing about it.

Insurance, and the gap after the port

Two points are specific enough to be worth stating carefully. First, a marine cargo policy that ends at the port does not cover an inland leg of twelve hundred kilometres across a frontier, and it does not cover a Casamance leg that passes through a third country either. Inland transit cover has to be arranged deliberately and it has to run across the frontiers rather than stopping at them. 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. This is the most commonly missed line on a first corridor shipment. 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, and a buyer who intends to place cover at home should be contracting on CFR or FOB instead. Confirm the position, including any local placement requirement in the destination country, with your insurance broker before the delivery term is agreed rather than afterwards.

What working in French actually changes

French is the working language of Senegalese administration, procurement and commerce, and it is the working language of Mali as well, so a Dakar corridor consignment is a French-language transaction from the tender to the transit declaration. That is not a cultural note; it has four concrete operational consequences.

• The tender is in French and so is the binding text. A Senegalese tender comes as a dossier with technical and administrative clause books, and the technical specification is the document a binder clause lives in. Where a translation is supplied, establish in writing which language version governs in the event of a discrepancy, because a translated specification that softens or hardens a limit is a contractual problem waiting to surface. Ask for the original French clause even if you intend to work from a translation, and have the translation checked by somebody who knows what an EN designation is.
• The decimal separator is a comma. This is a small point that causes real errors. In French convention a penetration written as 50,5 means fifty point five, and a figure written as 1.000 may be one thousand rather than one point zero zero zero. A specification transcribed carelessly between a French tender and an English certificate is a genuine source of disputes over limits, and the defence is to write units and, where any ambiguity exists, to write numbers out.
• Documents may need to be in French. Whether the safety data sheet, the certificate of analysis, the technical data sheet and the drum labelling have to be provided in French, and in what form, is a requirement of the destination and must be confirmed with the clearing agent. Do not assume an English pack will be accepted, and do not assume a machine translation of a safety data sheet is adequate — a safety data sheet is a document a driver, a storekeeper and an emergency responder may have to read at speed.
• The description discipline applies across languages. Keep the goods description word for word identical across the contract, the credit, the invoice, the packing list, the transport document, the conformity documentation and every transit declaration — and where two languages are in use, fix the French wording and the English wording once, in the contract, and never let either drift. A description that changes between documents is the most common self-inflicted cause of a hold anywhere in the world, and on a corridor movement it is also the slowest and most expensive to correct, because the correction has to be made in a country where neither party is standing.

Other authorities a buyer may encounter

The petroleum downstream sector is regulated through the ministry responsible for energy and petroleum, and environmental controls on the handling and storage of chemical products sit with the national environment administration. 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 Senegalese legal adviser and a licensed clearing agent. This page states no position on it, and nothing here is legal, customs, regulatory, insurance or compliance advice.
