South Africa has rewired its fuel supply chain away from the Arabian Gulf in response to the Iran war, with at least four US-origin tankers delivering roughly 165,000 tonnes of refined products to Durban in April alone and import schedules for May and June confirmed from West Africa, the Atlantic Basin and Asia.
The country that once bought 57% of its diesel from Gulf suppliers is now sourcing from the other side of the world — at a price.
Before the Hormuz crisis, Oman, the UAE and Bahrain together supplied 57% of South Africa's diesel imports. With the Gulf effectively closed, importers have pulled off one of the fastest supply-chain re-routings in the country's history — but longer voyages and freight premiums are now baked into every litre that lands.
From the Gulf to the Atlantic Basin
Industry body data confirms a decisive shift in the sources of South African fuel imports since the Middle East conflict closed the Strait of Hormuz. Importers forward-secured cargoes for April to June, increasingly sourced outside the Arabian Gulf — from West Africa, the Atlantic Basin and Asia — with US-origin product now arriving in volumes that would have been unthinkable a year ago.
The exposure was severe because diesel makes up around 66% of South Africa's total fuel imports, and the freight, mining, agriculture and construction sectors are almost entirely diesel-dependent. Diesel remains the most acutely supply-constrained product, followed by petrol and jet fuel.

Supply Secured — But at Elevated Cost
The good news is that no widespread supply disruptions are anticipated in the near term: May and June import schedules are confirmed, and the early-2026 fears of rationing and petrol queues have not materialised. The bad news is the cost structure. Landed prices are elevated because non-Gulf supply chains carry longer voyage distances and embedded freight premiums — one reason South Africa recorded among its steepest fuel price increases in roughly two decades earlier this year.

Recognising that the old pricing assumptions no longer hold, the Department of Mineral and Petroleum Resources is reviewing the Basic Fuel Price formula for diesel so that it accurately reflects the cost of importing from the new source markets — a technical change that will directly shape what SADC transporters pay at the pump.
A Regional Single Point of Entry
The shift matters well beyond South Africa's borders. Botswana, Lesotho, Eswatini, and parts of Zimbabwe and Namibia draw refined product through South African ports and inland depots, so the resilience of Durban's import chain is effectively a SADC question. Every additional dollar of freight premium on a Durban cargo eventually surfaces in pump prices from Gaborone to Harare.
The episode is also a live case study in supply-chain resilience: diversified sourcing, forward purchasing and port flexibility kept the fuel flowing where a just-in-time, single-region strategy would have failed. The same logic applies to any operator's critical inputs, from tyres to spare parts.
What This Means for SADC Logistics Operators
Supply is secure but structurally more expensive — budget for diesel landed costs to stay elevated even if Brent softens, and watch the Basic Fuel Price formula review, which will determine how fully those import premiums flow into the pump price. Operators should also revisit their own resilience: keep depot stocks above minimum, diversify suppliers where possible, and treat fuel hedging or price-adjustment clauses as standard contract practice in this environment.
