Viewpoint: Asean aluminium output to reach 2.7mn t
Singapore, 22 December (Argus) — Primary aluminium output in southeast Asia is
expected to rise to 2.7mn t in 2026, but supply tightness will likely persist in
the first quarter because the ramp up of new capacities will be gradual, while
export demand will remain strong. Southeast Asia will add 780,000 t of primary
aluminium output in 2026, driven by smelter expansion in Indonesia and new
smelters in Vietnam. Of which, 705,000t will come from Indonesia, sending the
country's expected total output to 1.55mn t. Key projects in Indonesia include
Chinese-backed Juwan in Weda Bay, Taijing in Morowali and Kaltara in North
Kalimantan. Taijing and Juwan, jointly developed by Chinese companies Tsingshan
and Xinfa, are expected to bring new capacity on line in 2026. Taijing plans to
start production in the third quarter of 2026 with expected output of around
180,000t, while Juwan expects to reach its full capacity of 250,000 t/yr in the
first quarter of 2026. Kaltara, developed by Indonesian firm Adaro and Chinese
firm Lygend, began phase one operations in October-December. It plans to ramp up
to its full phase one capacity of 500,000 t/yr by October 2026. These projects
form part of Indonesia's strategy to leverage its abundant bauxite reserves.
Indonesia's ample bauxite reserves and its success in developing a local nickel
supply chain over the past decade have attracted a growing number of Chinese
value-added producers seeking to integrate production chains in the country. In
addition, more Chinese value-added-product (VAP) producers have expanded
operations in Indonesia over the past eighteen months. They are looking to
diversify supply chains to pre-empt any disruptions if China reaches its
government-imposed annual capacity cap of 45mn t/yr for aluminium production.
China produced about 3.8mn t of primary aluminium during January-October, up by
2pc from a year earlier, according to China's National Bureau of Statistics.
This trend of building integrated supply chains locally in Indonesia is expected
to absorb part of Indonesia's additional primary aluminium output in the coming
years, given that some Chinese producers are likely to purchase aluminium to
process into VAPs. Meanwhile, exports will continue to grow. Indonesia's primary
aluminium exports rose by 71pc on the year to 414,600t in January–October, from
243,000t in the same period a year earlier. China remained the top destination,
taking 191,500t, or 46pc of total volumes. Exports of aluminium value-added
products — under HS code 7604, 7605, 7606, 7607, 7608, 7609, 7610 and 7616 —
increased by 40pc on the year to around 111,000t in the same period, according
to Global Trade Tracker data. Power stability and reliance on coal remain key
bottlenecks for Indonesian smelters. Coal-fired captive plants dominate power
supply, while renewable energy adoption is slow because of long lead times for
infrastructure development and high costs, despite government efforts to push
integration under its Net Zero 2060 roadmap, market participants said. In other
parts of southeast Asia, Vietnam's Dak Nong smelter will commence the first
phase of its operations, which has a nameplate capacity of 150,000 t/yr, in the
second quarter of 2026. The project is expected to produce 75,000t of aluminium
in 2026. Malaysia's Press Metal remains southeast Asia's largest integrated
aluminium producer with a capacity of 1.08mn t/yr. Press is expected to operate
at a utilisation rate close to 100pc for 2025 and 2026. Demand for Press'
products from its smelter in Sarawak, which are considered low-carbon products
in Turkey and Europe because of its hydro-powered smelter, will likely rise in
response to EU's tighter carbon boarder adjustment mechanism (CBAM)
requirements, effective on 1 January 2026. Indonesian state-owned producer
Inalum is expected to keep output at around 280,000t or raise it slightly to
about 285,000t in 2026. By Candice Luo Southeast Asia aluminium output outlook t
