West Africa Dry Bulk Route

What is the West Africa dry bulk route?

The West Africa dry bulk route is the corridor carrying Guinea bauxite to Chinese alumina refiners on Capesize and VLOC tonnage around the Cape of Good Hope, with a much smaller two-way trade in grain, cement and clinker into the Gulf of Guinea.

The corridor is defined by a single dominant flow rather than a balanced exchange. On most recent Clarksons and UNCTAD trade-flow estimates the Guinea to China bauxite lane has been the fastest-growing major dry bulk trade of the last decade, expanding from a marginal flow in the mid-2010s to roughly 110 to 130 million tonnes a year by 2025 as Guinean export capacity and Chinese refinery demand both scaled up. CRU and the producing-side data published by the Guinean operators (CBG at Kamsar, SMB-Winning across the Boke and Boffa concessions, and the Rio Tinto-linked developments) all point in the same direction: Guinea now sits at roughly two thirds of global sea-borne bauxite supply, and the overwhelming share of that tonnage discharges in China.

The standout feature of the corridor is its imbalance. The headhaul is enormous and the backhaul is essentially empty, because there is no comparable dry bulk cargo flowing from China back to West Africa. That shapes the freight economics, the vessel selection and the way owners position tonnage on the lane. The secondary trade, imports of grain, cement, clinker and steel into Nigeria, Ghana, Ivory Coast and their neighbours, runs on a different fleet and barely touches the bauxite story commercially, but it is what keeps a smaller geared market alive along the same coast.

Corridor at a glance

Lane attribute	Detail	Note / source
Origin region	West Africa, principally Guinea (Kamsar, Boke, Conakry)	Bauxite concessions at CBG, SMB-Winning and adjacent developments
Destination region	North and East China alumina refineries	Yantai, Lanshan, Qingdao and Bohai Rim receivers, per Clarksons trade-flow data
Key load ports	Kamsar, Conakry, Boke (river and transshipment anchorages)	Draught-restricted; transshipment common (CBG and SMB terminal data)
Key discharge ports	Chinese alumina-refinery receiving terminals	Bohai Rim and Shandong cluster, UNCTAD and Clarksons estimates
Headline distance	~12,000 to 13,000 nm one way (Kamsar to Qingdao via Cape of Good Hope)	Approximate; routing-dependent, flag for desk verification
Typical transit time	~40 to 50 days laden at slow-steaming speed	Approximate, speed and weather dependent
Dominant vessel classes	Capesize and VLOC on the bauxite headhaul	Supramax and Handysize on the import trade
Dominant cargo	Bauxite (alumina feedstock)	~110 to 130 Mt/yr Guinea to China, CRU and Clarksons estimates

The single number that matters on this corridor is the distance. At roughly 12,000 to 13,000 nautical miles one way around the Cape of Good Hope, Kamsar to a North China refinery is one of the longest mainstream dry bulk lanes in service, longer than the Brazil to China iron ore run, and the long ballast leg back to West Africa is the defining cost driver in any freight calculation.

What moves each way and on what ships

The corridor is asymmetric to a degree that few other major lanes match. The headhaul from Guinea to China is one of the largest single dry bulk flows in the world, while the return leg is almost pure ballast. Owners fix the round voyage knowing the ship earns on one leg and burns bunkers on the other, which is why the long ballast distance dominates the economics.

Read across the rows, the imbalance is the story. The bauxite headhaul runs on the largest mainstream tonnage because the parcel sizes and the long distance both favour Capesize and, increasingly, VLOC economics. The backhaul carries no comparable cargo, so the ship returns in ballast and the owner prices the round trip accordingly. The import trade into the Gulf of Guinea sits on an entirely separate fleet: geared Supramax and Handysize tonnage that can discharge at the shallower, less-equipped West African import berths, carrying grain, bagged and bulk cement, and clinker for regional cement grinding. Those two markets share a coast but very little else, and the import volumes are a fraction of the bauxite outbound flow.

Ports, chokepoints and distances

The corridor’s geography is concentrated at the Guinean load end and dispersed at the Chinese discharge end, with one decisive chokepoint in between.

• Kamsar, Guinea: the established bauxite export terminal (CBG), conveyor-loaded, with a river-bar draught that constrains how deep a Capesize can sail and feeds the transshipment practice on the coast.
• Boke and Boffa concessions, Guinea: the SMB-Winning export complex that drove much of the post-2015 volume growth. Heavy reliance on river loading and offshore transshipment to top off Capesize and VLOC tonnage that cannot load to full draught inshore.
• Conakry, Guinea: secondary load and general-cargo port, also a regional import gateway.
• Cape of Good Hope: the binding chokepoint on the Guinea to China leg. The corridor routes around the southern tip of Africa because the loaded Capesize and VLOC parcels are too large for the Suez Canal, which is why the lane is one of the longest in the dry bulk catalogue at roughly 12,000 to 13,000 nm.
• Suez Canal (alternative): a theoretical alternative for smaller, part-laden parcels, but not the working route for the dominant large-tonnage bauxite flow, so it functions as a marginal alternative rather than the main artery.
• North and East China refinery receivers: the discharge cluster around the Bohai Rim and Shandong, sized for Capesize draught at the tier-one ore and bauxite berths and feeding the inland Bayer-process refineries.

How the West Africa lane compares to the South America corridor

The West Africa and South America corridors rhyme structurally. Both are long-haul lanes into China that route loaded tonnage around the Cape of Good Hope, both run on Capesize and VLOC economics, and both feature a long ballast return that dominates the freight calculation. A broker who understands one corridor will recognise most of the moving parts in the other.

The difference is the cargo and the maturity of the trade. The South America corridor is built on iron ore from the Brazilian export complex, a mature, decades-old flow on a dedicated Valemax and Capesize fleet. The West Africa corridor is built on bauxite, a much younger flow that barely existed at scale before the mid-2010s and has grown faster than any other major bulk lane since. Both leave their return legs largely empty, so the comparison is less about the backhaul, which is weak on both, and more about the headhaul cargo. The pending Simandou iron-ore ramp-up adds a further twist: it would give West Africa a second long-haul iron-ore flow into China that looks even more like the South America corridor, though the volume and timing remain forward estimates rather than booked trade.

Common confusions about the West Africa lane

A few persistent misconceptions get this corridor wrong at the cargo-order stage.

• Assuming iron ore already dominates West Africa. It does not. Today the volume leader on the corridor is bauxite, by a wide margin, and the large West African iron-ore flow is still pending on the Simandou ramp-up rather than running at scale. Treating the lane as an iron-ore corridor today misreads what is actually on the water.
• Underestimating transshipment. The shallow Guinean river bars mean a large share of bauxite is loaded through offshore transshipment rather than straight off a deep-water berth, which changes loading rates, laytime counting and the load-operation risk profile. A fixture written as though the ship loads conveyor-direct at a deep berth will misprice the laytime.
• Treating the backhaul as a revenue leg. There is no significant dry bulk cargo flowing from China back to West Africa, so the return is essentially ballast. Owners who model the round voyage expecting a paying backhaul will mis-set the freight.
• Confusing the bauxite headhaul fleet with the import fleet. The Capesize and VLOC tonnage that lifts bauxite to China is not the fleet that serves the Gulf of Guinea grain, cement and clinker imports. Those are smaller, often geared Supramax and Handysize ships discharging at shallower berths, a separate market on the same coast.

Where to find live rates for this corridor

This page does not carry live freight numbers. Rates on the West Africa lane move with the wider Capesize market and shift continuously through the trading session, so any figure printed here would be stale within days. For current market levels read the Baltic market page, which tracks the published route assessments the desk reads off the screens, and use the rate calculator to sketch a voyage estimate for a specific parcel and laycan. For a firm number on a real cargo, work the position through a broker against the live Baltic Exchange and Clarksons assessments rather than a static figure on a content page.

Scope and what this page does not cover

This page describes the West Africa dry bulk corridor: what moves on it, the vessel classes that serve it, the ports and the Cape of Good Hope chokepoint, the headhaul and ballast structure, and how it compares to the South America iron-ore lane. It does not forecast bauxite, alumina or freight prices, predict the timing or volume of the Simandou iron-ore ramp-up, opine on which Guinean concession or Chinese refinery pair to fix next, or carry live rate quotes. For those, work with a desk broker and chartering counsel against current Clarksons, CRU, UNCTAD and Baltic Exchange data.
