铝：美国加征关税后的市场变化

Report Summary 1) Report Industry Investment Rating The provided content does not mention the industry investment rating. 2) Core Viewpoints of the Report - After the implementation of US aluminum tariffs in 2025, the import volumes of primary aluminum, aluminum products, and aluminum derivatives in the US decreased. The tariffs not only suppressed US demand but also led to the consumption of the country's aluminum inventory. The change in trade flow caused by the tariffs did not result in inventory accumulation outside the US due to the increased demand in non - US countries [2][4]. - Currently and for some time in the future, the rising spot premium caused by the consumption of primary aluminum inventory in the US makes exporting to the US more advantageous again. Primary aluminum from Canada and non - US countries and regions is expected to flow more to the US, reversing the trade flow from April to August. Considering the sustained consumption growth and limited new production capacity, the supply - demand relationship of primary aluminum outside the US will remain temporarily tight, and global aluminum prices will still be strongly supported [2][22]. 3) Summary According to Related Contents Impact of US Aluminum Tariffs on Domestic Trade - In 2025, the US gradually increased aluminum tariffs. On March 12, the tariff on imported aluminum products was raised to 25%, and on June 4, it was further increased to 50%. On August 15, the scope of aluminum tariffs was expanded [4]. - In August 2025, the US primary aluminum import volume was 74,000 tons, 83,000 tons less than the same period last year. From January to August, the cumulative import volume was 1.221 million tons, 244,000 tons less than the same period last year. The import demand decreased significantly after the tariff implementation. For aluminum alloy, the import volume from January to August was 146,000 tons, with a slight increase month - on - month, and the cumulative import volume decreased only slightly compared with the same period in 2024 [4]. - For aluminum products, from April to August, the average monthly net import volume was 202,000 tons, 28,000 tons less than that from January to March and 56,000 tons less than the average monthly net import volume in 2024. For scrap aluminum, since it was not included in the tariff list, the US import demand was stimulated. From January to August, the net import volume increased by about 72,000 tons. Overall, from January to August, the reduction of imported aluminum element supply in the US was in the range of 400,000 - 500,000 tons, and the US increased the consumption of its own inventory [5]. Impact on International Trade and Market - After the implementation of US aluminum tariffs, Canada's exports to the US decreased significantly. In 2024, Canada exported about 1.828 million tons of primary aluminum to the US and only about 34,000 tons to non - US countries. From January to August 2025, Canada's total primary aluminum export volume decreased by 277,000 tons compared with the same period in 2024, with a decrease of about 432,000 tons in exports to the US and an increase of about 152,000 tons in exports to non - US countries [14]. - From early April to the end of August 2025, the overseas visible inventory of aluminum ingots decreased from about 1.14 million tons to about 1.06 million tons, indicating that the consumption in non - US countries increased and offset the decrease in US import demand [16].
