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

China is now a major swing supplier of aluminum to Western markets that are reeling due to the Iran War's impact on production in the Gulf. The world's largest aluminium producer, China, has increased exports of metals and alloys as well as semi-manufactured goods (semis) to help cushion the impact in the global supply chain.

The timing is fortunate from a?China perspective. The?national?production has reached record highs, despite a stuttering growth in domestic demand.

While?China's imports have temporarily relieved the market, they may not be the best solution for the long-term.

TAX GAP: MIND THE TAX GLOBAL

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

The fact that the bulk of China's exports are alloys and products like bar, rod, and tube should not be a surprise. 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 is Western aluminium that has been stored in bonded storage and is now being rerouted back to Western markets. In January-June, China "exported", 9,700 tons to the U.S. but U.S. Customs only counted 70 tons in Chinese imports during the same period. The exports of alloy have grown faster and nearly doubled to 238,500 tonnes in the first six months of 2026. In fact, China became a net alloy exporter in June for first time since 2019. China also produced an additional 500,000 tons in semis. The country's total volume was up 18% on a year-on-year basis, at 3.2 millions?tons, from January to June.

The pace of shipments continues to accelerate. The 695,000-ton total for June was a monthly record.

DISPLACEMENT - These products can't replace the metals and alloys lost in the Gulf. They 'act to suppress the demand for unwrought steel by substituting it further up the processing 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, however, has changed the dynamic once again. It has reinvigorated outbound flows due to a combination of a structurally stressed Western Supply Chain and a lax internal market.

Cost of Comfort

Citi analysts claim that the Chinese demand for aluminium has flattened in the first half 2026. The end-use tracker of the bank fell by 0.4% year-on-year due to weakness in the traditional end-use sector, particularly 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 is no longer paying the war premium. The price of aluminum has dropped from $3,787.50 a ton, which was a four-year-high at the beginning of June, to $3,270.00. This is only $100 higher than it was on February 28, before Israel and the U.S. attacked Iran. The longer it takes the West to balance its economy with Chinese products, the higher the long-term costs for Western semi-finished product manufacturers.
