Alumina steady-to-soft as spot tightens, deepening losses fail to spur cuts

Domestic spot alumina prices edged down slightly last week amid flat trading activity. Recent alumina price movements were mainly attributed to earlier concentrated restocking by downstream buyers, which has led to accumulating inventories at rail stations and smelters. Coupled with supply-side maintenance-driven output cuts that are still building, readily available spot volumes have tightened relatively. Only sporadic tender deals were heard recently, leaving prices in a temporary steady phase. On the bauxite front, domestic ore prices saw limited movement last week. Supply-side bottlenecks are unlikely to ease in the near term, with mines prioritising captive supply, leaving little excess spot material available. For imported ore, freight rates rebounded slightly and consecutively last...

AL Circle Analysis: Guinea’s 150Mt bauxite cap, China’s import swings, US tariffs draw aluminium Q4’26

The global aluminium supply chain is facing a series of changes that extend from bauxite mines and alumina refineries to smelters, regional premiums and finished-metal trade. In 2026, the market’s direction is being shaped not only by production volumes but also by freight costs, export restrictions, shifting Chinese demand and tariffs. Developments across Guinea, Australia, China, Europe and North America point to a market where access to supply is increasingly as important as the availability of raw materials. Bauxite supply: Guinea’s cap meets a well-stocked China, but is it stable? Guinea remains central to the seaborne bauxite market, with its shipment connections to China demonstrating the importance of reliable logistics. A new sea-rail route has enabled a Guinea bauxite shipment...

EU announces anti-dumping duties on Chinese fused alumina

The European Commission has officially announced imposition of provisional anti-dumping duties on fused alumina imports from China. This time, it is a move to resolve to protect Europe’s domestic industry from market distortions. Commission Implementing Regulation (EU) 2025/1456, adopted on July 17, 2025, delivers a stern warning to China’s state-backed industrial juggernaut: unfair trade practices will no longer be overlooked. Image for referential purposes only At the core of the Commission’s decision lies the recognition that fused alumina, rather commonly known as artificial corundum, derived from melting bauxite or aluminium oxide at over 2,000 °C, has been imported from China at dumped prices, causing material injury to the European Union’s domestic producers. The action follows a...

World alumina production in May rebounds by 3% M-o-M , but with a dip in daily output

In May 2025, world alumina production recorded a slight rise month-on-month following a slump in April, but not without a twist. While total monthly output rose to 12.626 million tonnes, marking a 3 per cent increase, the daily average slipped slightly from 408,400 tonnes to 407,300 tonnes, according to the International Aluminium Institute (IAI). The decline in daily output is likely due to one fewer operational day in May’s calendar. Of the total alumina production in May, metallurgical-grade ore accounted for 11.841 million tonnes, making up 93.78 per cent of the total output, while chemical-grade output stood at 785,000 tonnes, contributing 6.22 per cent to the overall production. Notably, the growth in May alumina production was exclusively driven by metallurgical-grade ore, as...

Aughinish alumina project under survey by Environment Protection Agency

A Clare-based environmental group is calling on the Environmental Protection Agency (EPA) to reassess the potential ecological impact of a new development on the Shannon Estuary. The EPA recently granted Aughinish Alumina a new licence to extend its dredging operations near Foynes Port, permitting the dumping of dredged material at a newly designated site close to Foynes Island. Futureproof Clare has voiced strong opposition to the renewal of the permit, warning that it could result in the disposal of an amount of potentially contaminated muddy sand equivalent to 5,000 double-decker buses annually. Campaign spokesperson Sinéad Sheehan has urged the EPA to exercise greater due diligence in its oversight of the development. In response to a query from Clare FM, the EPA confirmed it had...

US alumina imports surge as domestic output falters — a sign of growing reliance?

While bauxite imports to the United States show a steady course, alumina tells a different story. In the first quarter of 2025, US alumina imports reached 439,000 tonnes, marking a significant uptick both year-on-year and quarter-on-quarter. The data revealed a 24.7 per cent rise from the previous quarter (352,000 tonnes) and an even sharper 53.5 per cent leap compared to Q1 2024 (286,000 tonnes), signaling a marked shift in sourcing dynamics. The upward trajectory, which began in Q2 2024 with 325,000 tonnes, gained momentum through Q3 (378,000 tonnes), momentarily slowed in Q4 (352,000 tonnes), and rebounded strongly in Q1 2025. This pattern, when juxtaposed with falling domestic production, paints a clear picture: the US is becoming increasingly dependent on imported alumina. Brazil and...

Why alumina is left out: A study unpacks the logic behind CBAM exclusion

The European Union’s hallmark policy in the view of equitable trade and environment protection—the Carbon Border Adjustment Mechanism (CBAM)—seems fair on the surface, as long as its framework remains focused on preventing carbon leakage and blocking the influx of cheap, high-emission goods into the domestic market. Under CBAM, a carbon price is levied on imported goods, aligned with the carbon costs EU producers incur under the Emission Trading System (ETS). That sounds like a just deal for domestic producers, ensuring a level playing field. But what about EU-headquartered companies that relocated their operations abroad to escape carbon taxes? Here's where the issue arises as these companies will be required to purchase certificates that reflect the carbon emissions embedded in their...
