The global aluminium industry witnessed a week shaped by supply-side adjustments, expansion plans and evolving trade dynamics. From Guinea’s potential bauxite export restrictions and fresh alumina capacity developments in India and Vietnam to Rio Tinto’s operational gains, Vedanta’s record financial performance and ongoing tariff discussions across North America, the sector continued to balance growth ambitions with geopolitical, regulatory and market uncertainties. Meanwhile, corporate consolidation, supply-chain resilience and resource security remained at the forefront of industry developments.

Bauxite highlights: Guinea’s curb, Jamaica’s ambition and India’s growth drive

Guinea is expected to introduce reforms next month aimed at restricting bauxite exports after a surge in supply pushed global prices sharply lower. It would mark a major shift for a country that exported nearly 183 million tonnes in 2025. If introduced, the cap could remove almost 33 million tonnes from the market.

Declining bauxite prices and rising freight costs have caused surplus concerns. For Guinea, hosting about 7.4 billion tonnes of bauxite reserves – the largest in the world, the focus appears to be shifting from maximising volumes to preserving value. Learn more.

The Jamaica Bauxite Institute (JBI) is urging citizens to avoid occupying bauxite-bearing lands, highlighting growing concerns over unauthorised settlements on areas designated for mining, agriculture and future development projects. The statement indicates the urgency to mitigate the output decline post-Hurricane Melissa in October 2025. It is also an opportunity to deepen Jamaica’s footprint in the bauxite industry just as speculations stir the market about Guinea’s updated bauxite export restriction cap tightened at 150 million tonnes per annum (MTPA).

India’s bauxite industry is entering a new phase of expansion as domestic production and imports rise simultaneously. India produced around 25 million tonnes of bauxite in 2025, slightly higher than the 24 million tonnes recorded in 2024. However, despite increasing domestic mining activity, imports also surged sharply to nearly 4.9 million tonnes from 4.1 million tonnes a year earlier, marking year-on-year growth of around 20 per cent.

Alumina scoop: 730kt output gap, Vietnam’s expansion push, Aughinish’s export crisis

Global alumina production in April 2026 stood at 11.92 million tonnes, declining month-on-month by 5.74 per cent from 12.65 million tonnes produced in March 2025. Looking at the figure closely, a year-on-year drop of 2.59 per cent from the production volume of 12.24 million tonnes can be noticed as well. Pipeline alumina projects expected to offset about 25 per cent of the 730,000-tonne production gap. However, commissioning and ramp-up constraints mean their supply impact is likely to be modest in 2026, with more meaningful contributions expected from 2027 onward.

The Vietnamese industrial conglomerate Truong Hai Auto Corporation (THACO) is accelerating its ambitions in the country’s bauxite and alumina sector, unveiling a slate of proposed mining and processing projects in Lam Dong Province worth an estimated USD 4.4 billion. The proposal indicates the company’s long-term strategy to solidify its imprint across the aluminium value chain of Vietnam, from the upstream ore extraction to the downstream processing and industrial manufacturing.

Vietnam is also commencing operations at its first aluminium electrolysis plant around Q2 2026, according to project officials in Lam Dong province. Covering around 129 hectares with total investment exceeding VND 18 trillion (USD 720 million), the project is expected to initially produce 150,000 tonnes of aluminium annually. The facility forms the final stage of Vietnam’s broader bauxite-to-aluminium industrial chain, linking bauxite mining, alumina refining and primary aluminium production.

The European Commission has decided not to impose sanctions on Ireland-based Aughinish Alumina at present, amid concerns that restrictions could disrupt Europe’s already fragile aluminium supply chain. Aughinish exported over 80 per cent of its alumina production to Russia during the first quarter of 2026. Irish exports to Russia rose by approximately 55 per cent between 2021 and 2025, increasing from EUR 539 million to EUR 836 million.

Irish authorities are examining export data submitted by Aughinish Alumina after questions were raised over the volume of alumina shipped from the Limerick-based refinery to Russia. Ireland's Minister for Enterprise, Trade and Employment, Peter Burke, said the figures may not accurately reflect the company’s actual export distribution.

Aluminium weekly: Japan’s uncertainty, Alba’s Aluminium Dunkerque acquisition

Japan’s aluminium market is facing growing uncertainty as escalating tensions in the Middle East begin disrupting one of the country’s most critical supply routes for the metal. For years, Japan has relied heavily on Gulf producers such as the UAE and Saudi Arabia, with the region supplying around 20 per cent of the country’s raw aluminium imports thanks to its low electricity costs and large-scale smelting capacity.

Aluminium Bahrain (Alba) is expected to acquire Aluminium Dunkerque, the EU’s largest primary aluminium smelter, in a USD 2.2 billion deal, subject to EU FSR clearance and other regulatory approvals. The deal will mark a significant step in Alba’s strategy to build a global low-carbon aluminium platform. The transaction was announced jointly with American Industrial Partners, the current owner of Aluminium Dunkerque, and Bpifrance, which will acquire a minority stake in the company alongside Alba.

Tariff talks: Mexican aerospace braces for impact; Canada prepares action plan

Discussions around the United States-Mexico-Canada Agreement (USMCA) are set to begin as tariffs on aluminium, steel and other goods continue to create uncertainty across North America. Jamieson Greer said tariffs will likely remain in place as long as the US running a trade deficit with major trading partners. Mexico’s aerospace industry prepares for the new USMCA review phase and continued US tariffs on aluminium, steel and derivative products reshape the operating landscape. While the process was initially expected to conclude by July 1, discussions among the three member nations have extended negotiations through the week of July 20.

The Canadian government announced plans to extend key steel and aluminium tariff measures for another year, seeking to safeguard domestic production from global trade distortions and import diversion. Subject to final approval, Canada's steel tariff-rate quotas for countries outside the Canada-United States-Mexico Agreement (CUSMA) will remain in place until June 27, 2027. Under the framework, imports that exceed quota limits will continue to face a 50 per cent tariff.

Stronger earnings, capacity expansion and trade recovery reinforce momentum

Rio Tinto’s New Zealand aluminium operations delivered a robust financial performance in 2025, with parent company Pacific Aluminium (New Zealand) reporting a net profit of USD 176 million, backed by higher aluminium sales revenue and increased production at the Tiwai Point smelter. The company is considering to partially restart New Zealand Aluminium Smelter in Tiwai Point, and is planning to restart Line 4, a potline that has been shut down since 2020.

On the other hand, Rio Tinto’s aluminium exports from Canada to the US have largely returned to pre-tariff levels, with US-bound shipments recovering to around 80 per cent of North American sales. Strong US demand, tight regional supply and higher Midwest premiums have helped offset tariff impacts, reinforcing Canada’s strategic supply role.

Vedanta Limited delivered its strongest-ever financial result in FY26, propelled by record earnings particularly by the segments of Aluminium, Oil & Gas and Power. Annual revenue of INR 1,740.75 billion (USD 18.27 billion) for FY26 marked a 15 per cent Y-o-Y increase, EBITDA amounted to INR 559.76 billion (USD 5.87 billion), climbing 29 per cent Y-o-Y and the Profit after tax (PAT) recorded an all-time high of INR 250.96 billion (USD 2.63 billion), rising 22 per cent Y-o-Y. 

Vedanta Aluminium awarded INR 285.8 million (USD 3 million) to Texmaco Rail & Engineering for the supply of one BTAP alumina transportation rake along with one brake van or guard vehicle. The order follows another contract awarded earlier by Vedanta Aluminium worth INR 571.5 million (USD 6 million), under which Texmaco supplied and commissioned two BTAP rakes and two BVCM units.
