Andy Home: ROI-China eases Iran War Aluminium Shock, but at a Cost

China is now a major swing?supplier for aluminium in a Western market reeling from the loss production in the Gulf due to the Iran War. The top aluminium producer in the world has increased exports of metals, alloys and semi-manufactured goods (semis) to help cushion the impact on the global supply chains.

China views the timing as fortunate. The national production has reached record levels, despite a slowdown in domestic demand.

While China's exports may have temporarily relieved the market, a long-term problem could be lurking.

Mind the Tax Gap

Tax code is the primary factor that determines the composition of China's aluminum exports. The primary metal is subject to a 30% tax on exports, whereas alloys and semis are exempt.

No surprise then that the majority of China's export volumes is in the form alloys and products like bar, rod, and tube. It's not that primary metal exports haven't responded. The first-half volume rose 32% on an annual basis to 38,400 tons. However, the majority of this metal likely comes from Western aluminum stored in bonded storage and is now being rerouted back to Western markets. China, for example, "exported" 9700 tons to the U.S. from January to June but U.S. Customs only counted 70 tons of Chinese imported goods during the same period. The exports of alloy have grown faster and nearly doubled to 238,500 tonnes in the first half of 2026. In fact, China became a net alloy exporter in June for first time since 2019. In the meantime, China produced an additional 500,000 tons of semis. The cumulative volume was up?18% on an annual basis at 3.2 millions tons from January to June.

The pace of shipments continues to accelerate. The tally for June of 695,000 tonnes was a monthly record.

DISPLACEMENT These products exports cannot directly replace the primary metal and alloy units lost in the Gulf. They suppress the demand for unwrought steel by substituting it at a later stage in the production chain.

The rub is in the details. This has led to a shift of manufacturing from other countries to China. China's semis are a source of controversy for Western policymakers, and many countries have responded with anti-dumping duties on a variety of products. Beijing has removed the 13% VAT export rebate for products in December 2024, partly to address these concerns.

Last year, exports dropped 18% to 890 000 tons as Chinese processors shifted to the domestic market.

The Iran War?has again changed the dynamics, reinvigorating the outbound flow thanks to a combination of a structurally stressed Western Supply Chain and a lax internal market.

Cost of Comfort

Analysts at Citi say that the Chinese demand for aluminium has flattened in the first half 2026. The end-use index of the bank fell by 0.4% on an annual basis, reflecting weakness in traditional sectors such as construction.

International Aluminium Institute reports that primary aluminium production grew 2.2% in the same time period. ?The country's smelters are now ?operating close to or even slightly above Beijing's mandated 45-million-ton-per-year capacity cap.

Stocks at the Shanghai Futures Exchange, although they have fallen in recent weeks, still remain higher than London Metal Exchange inventories of 358,000 tonnes, which includes metal stored off-warrant.

China has the ability to keep exports high for some time.

The LME market has been reassured by this, as aluminium has lost most of its war premium. The price of aluminium for the three months has fallen from its four-year-high of $3,787.50 a ton, at the beginning of June, to $3,270.00. This is only $100 more than before the U.S. Israel and the United States attacked Iran on 28 February. The longer the West relies on Chinese products to balance the market, the higher the long-term costs for Western manufacturers.
