Overseas Market: As of April 30, 2025, the FOB Western Australia alumina price was $348/mt, with an ocean freight rate of $20.50/mt. The USD/CNY exchange rate selling price was around 7.29. This price translates to approximately RMB 3,114/mt for the external selling price at major domestic ports, which is RMB 218/mt higher than the domestic alumina price. The alumina import window remained closed.
Summary: With the commissioning of new capacities and the resumption of production from maintenance capacities, the operating capacity of alumina has rebounded significantly, with a WoW increase of 3.48 million mt/year in the last week before the holiday. In the short term, some alumina refineries have plans for maintenance and production cuts, but at the same time, new alumina capacities will further ramp up production, and the operating capacity of alumina may show slight fluctuations. On the cost side, caustic soda prices have remained largely stable, while bauxite prices have decreased, leading to a decline in alumina costs and alleviating the loss pressure on alumina refineries. Overall, the tightening of alumina spot supply caused by the concentration of maintenance and production cuts in the early stage is expected to ease, and short-term prices are expected to fluctuate.
