Alumina Price Trend Q3 2025
In Q3 2025, the global alumina market experienced a mixed but modest upward trend of 2–3% in prices compared to the previous quarter, driven by a combination of supply-side developments and regional demand variations. New supply additions from Indonesia and India continued to pressure the market, while localized production curtailments, especially in China and Australia, helped balance some of the oversupply.
At the same time, bauxite supply risks, particularly from Guinea, and logistical disruptions added short-term volatility. Demand growth remained steady but subdued, closely tied to aluminium production trends, which faced regional constraints. Overall, the market reflected a structurally loose supply environment, with prices largely fluctuating near cost floors, and any gains remaining fragile and regionalized rather than broad-based.
China
Alumina Export prices FOB Shanghai, Grade- Purity: 98.5%min.
According to PriceWatch, in Q3 2025, the alumina price trend in China experienced a slight decline resulting in a 0.83% decrease compared to Q2 2025. Market sentiment was cautiously subdued as supply growth from new production capacities outpaced downstream demand from the aluminium smelting sector, which remained stable but constrained by capacity limits and muted export demand.
Raw material costs including bauxite and caustic soda were relatively stable, providing limited upward pressure on prices. However, alumina prices rebounded modestly in September 2025 with a 0.64% increase, supported by tightening supply conditions as some high-cost producers reduced output and inventories began to normalize.
Export activity offered minimal support during ongoing global demand uncertainty. Overall, the alumina market in China during Q3 2025 reflected a slight oversupply environment with prices trending downward initially but showing signs of stabilization heading into the final quarter of the year.
Australia
Alumina Export prices FOB Brisbane, Grade- Purity: 98.5%min.
In Q3 2025, the alumina price trend in Australia experienced a slight price increase of 3.68% compared to Q2, reflecting a cautiously positive sentiment amid tightening supply and steady demand growth. The uptick was driven by a combination of constrained bauxite availability impacting refining operations and elevated raw material costs, particularly energy and transportation expenses, which pressured producers to adjust output levels strategically.
Export activity stayed robust, supported by sustained demand from key Asian markets, though logistical challenges intermittently affected shipment volumes. Notably, alumina prices rebounded modestly in September 2025 with a 0.64% decrease, attributed to short-term inventory corrections and mild softening in downstream alumina consumption.
As a whole, the market outlook heading into Q4 2025 suggests continued price resilience, underpinned by supply-side constraints and stable demand, although potential volatility remains as producers navigate cost pressures and global economic uncertainties.
