Guinea, the world’s leading bauxite producer, is considering introducing export quotas for mining companies as early as this month, according to sources familiar with the discussions, as declining global prices and rising shipping costs place pressure on revenues.
The move follows a surge in Guinea’s bauxite exports, which rose by 25 per cent in 2025, with more than 70 per cent destined for China. However, global prices for the aluminium feedstock have since fallen by between 20 and 35 per cent from their 2025 peak, partly linked to supply disruptions from the country, released on Monday, March 16.
Industry and government sources indicate that quotas for individual mining operations are under active review, although no final decision has been taken and key implementation details remain unclear. The proposed measures are expected to primarily target large-scale producers.
Guinea accounts for over 40 per cent of global bauxite supply and has in recent years intensified efforts to restructure and regulate its mining sector, which also includes significant deposits of iron ore, gold and lithium. The policy considerations come as freight costs continue to rise, driven in part by geopolitical tensions, including the ongoing conflict involving Iran, further compressing margins for exporters.
Across the continent, resource-rich African nations are increasingly adopting stricter policies—ranging from export controls to higher royalties and local processing requirements—in a strategic bid to maximise value from their natural resources.
