WEEKLY: Guinea bauxite prices under pressure as freight slide revives supply

China's domestic bauxite prices held steady last week. Supply tightness at China's inland mines persisted, prompting some traders to blend and sell ores sourced from Turkey and Pakistan. Meanwhile, the sharp decline in ocean freight rates restored arbitrage margins for bauxite from non-mainstream origins; imports from origins compatible with domestic bauxite blending are likely to rise.

In terms of imported bauxite, freight rates showed no sign of bottoming out. Rates on the Baltic Exchange C3 route fell to around US USD 30 per tonne, with November-loading vessel offers quoted near US USD 29 per tonne. The sustained freight drop revived shipment plans for small and mid-sized Guinean miners, pointing to potential supply ramp-up for Guinean bauxite. Guinean ore offers increased markedly last week; however, weighed down by falling alumina prices and collapsing freight costs, refineries showed tepid buying interest and strong price-cutting intent. Bid prices slipped to roughly US USD 70 per dry metric tonne, while seaborne traders' cost bases were concentrated at US USD 72–73 per dry metric tonne, leaving deals hard to conclude.

According to Mysteel research, several Guinean miners lifted November vessel bookings: Miner A raised planned loadings to 7 cargoes from 4 in October; Miner B to 4-5 from 3; Miner C to 3 from zero. Other miners were canvassing the tanker market for fixtures, meaning the booked increments understate the potential actual November shipment lift, and real dispatch growth could be larger. Separately, aware of freight-market exposure, some junior miners have actively negotiated 2027 annual freight contracts to secure ore delivery commitments for next year.

Overall, post-National-Day sentiment flipped, with participants broadly expecting a phased pullback in bauxite prices. Alumina refineries' integrated inventories stayed relatively elevated, rigid restocking appetite was muted, and thin physical trade further capped imported bauxite values. Mysteel sees near-term downside pressure persisting on Guinean imported bauxite prices.

For 9-15 October 2026, global bauxite shipments from major producing countries totalled 5.28 million tonnes, with 4.59 million tonnes destined for China, up 28.58 per cent week-on-week; seaborne floating inventory stood at 16.92 million tonnes, predominantly from Guinea and Australia. Last week's shipments to China rose visibly, driven jointly by Guinea and Australia.

By origin: Guinean shipments to China reached 3.61 million tonnes, up 30.69 per cent week on week; the freight-rate tailwind will feed into mid-to-late November loadings and was not yet reflected in the current reporting window. Guinea's rainy season eased, exerting only marginal drag on mining and inland haulage. Australian shipments to China came in at 0.98 million tonnes, up 21.34 per cent week on week, lifted by fixture scheduling.

Combined seaborne floating tonnage for Guinea and Australia was 16.92 million tonnes; in-transit bauxite stocks remained high, implying sustained arrivals at Chinese ports ahead. On the freight front, C3-route rates retreated alongside volatile-but-firm international crude prices, pushing ocean freight lower overall.

In summary, last week's shipment strength was chiefly a concentrated dispatch spike from Guinea and Australia; elevated floating inventory continues to buttress domestic raw-material supply, keeping a high-port-stock scenario on the table.

During 9–15 October 2026, 35 bauxite carriers, mainly from Guinea and Australia, discharged at major Chinese ports, delivering 4.85 million tonnes, up 25.15 per cent week on week. As of 16 October 2026, bauxite inventories at China's key ports totalled 32.44 million tonnes, down 1.07 per cent week on week.

Port stocks edged lower overall last week, though regional divergence was pronounced. Several ports drew down inventories: some on normal arrivals paired with stronger refinery off-take; others simply saw lighter receipts with steady withdrawals. On the demand side, alumina-plant operating rates held stable with no large-scale curtailments flagged; trade flowed mainly on term contracts with rigid, needs-based procurement. Aggregate off-take remained insufficient to absorb concentrated arrivals.

With seaborne floating bauxite elevated and more vessels scheduled, latent port-build pressure endures. Near-term port stocks will likely hold at high levels; monitor overseas shipments, port destocking pace, and alumina-refinery drawdown pace closely.
