Dangote Petroleum Refinery is considering restricting Premium Motor Spirit (PMS) sales to major Nigerian marketers that continue to import petrol, as the refinery raises concerns over product quality, market transparency and the protection of its brand.
The proposed measure could take effect as early as this week, subject to further consultations and any last-minute intervention, according to sources familiar with the refinery’s position.
The potential restriction comes as Nigeria’s downstream petroleum market undergoes a major shift from decades of dependence on imported refined products towards increased domestic production.
At the centre of Dangote Refinery’s concerns is the alleged blending of imported petrol with products purchased from the refinery before the mixture is distributed to consumers.

The refinery is concerned that if imported PMS of uncertain quality is mixed with its products, consumers may be unable to distinguish between fuel supplied directly by Dangote and products subsequently blended or handled by marketers.
The Punch reported that a source familiar with the refinery’s position said, “*It is difficult to understand why we would invest heavily in producing high-quality petroleum products for Nigerians, only for those products to be mixed with imported products of uncertain quality and the resulting product to be associated with the refinery.”.*
The refinery has also raised concerns about Nigeria’s ability to independently test and certify imported petroleum products.
*The Punch* further reported that sources familiar with the refinery’s position said the regulator lacks a standard laboratory and sufficient quality-control infrastructure to independently verify the specifications of some imported petroleum products
That concern has become more significant as Dangote’s 700,000-barrel-per-day refinery has expanded domestic production and emerged as a major supplier of refined products in Nigeria and international markets.
The refinery’s position reflects a broader argument that continued petrol imports are becoming increasingly difficult to justify as Nigeria develops substantial domestic refining capacity.
The United States Energy Information Administration recently highlighted the transformation in Nigeria’s refined-product trade, identifying the Dangote refinery as a major contributor to the country's rising seaborne petroleum-product exports.
Nigeria’s seaborne petroleum-product shipments averaged about 561,000 barrels per day in the second quarter of 2026, compared with an annual average of just 79,000 barrels per day in 2023.
The development underscores how rapidly Nigeria’s role in the international refined-products market has changed since the Dangote refinery began ramping up operations.
The refinery has also gained a growing presence in international aviation-fuel markets. Its jet fuel has been supplied to major overseas markets, including Europe and the US, where its exports have become increasingly significant.

For Dangote, the dispute is therefore not simply about controlling who buys its petrol. It is also about protecting the reputation of products carrying the refinery’s name at a time when it is seeking to establish Nigerian refined petroleum products as a competitive alternative to imports.
Any decision to restrict supplies to marketers that continue importing PMS could further reshape Nigeria’s downstream market, putting additional pressure on major fuel distributors to choose between domestic supply and imported petrol.
It could also intensify the debate over whether Nigeria should continue allowing significant petrol imports while one of Africa’s largest refineries is operating at scale and increasingly supplying both domestic and international markets.
