美钢铝关税涉及范围扩大，后市如何看待

1. Report Industry Investment Rating No information provided. 2. Core View of the Report - The expansion of the US steel and aluminum tariff scope on August 15 did not change the tariff rate. The impact on aluminum prices is relatively small compared to the adjustment on May 30. The tariff is expected to cause a price correction rather than a reversal, and the correction range is not expected to be deep. In the medium - term, aluminum prices are still optimistic, and the correction is regarded as a restocking opportunity [3][16]. - The impact of the tariff expansion on demand needs to be verified by subsequent retail data. The previous tariff increase made PPI rise but had little impact on CPI, indicating that most of the tariff was absorbed by manufacturers and had less impact on demand [14]. - The US tariff policy adjustment affects the entire non - ferrous metal sector, which will be reflected in demand and then affect prices. The tariff range may be adjusted according to relevant categories, and the policy uncertainty in the second half of 2025 is decreasing [18]. 3.

Newly Added Tariff - Covered Product Areas - Automobile manufacturing: Galvanized steel sheets, aluminum alloy wheels, engine brackets and other key components [4]. - Construction engineering: Steel structure beams, aluminum alloy window and door frames, prestressed concrete steel strands [4]. - Consumer goods: Tin - plated sheets for cans, household appliance shells, kitchen cookware [5]. - Industrial equipment: Transformers, compressor valve plates, hydraulic system pipes, structural parts of mining machinery and industrial processing machinery [5]. China's Aluminum Exports to the US - Direct exports of aluminum materials: Since 2018, China's exports of unforged aluminum and aluminum materials to the US have decreased significantly. In 2024, the export volume was 25.4 tons, a 62% decrease from 2017. The proportion of exports to the US in total exports dropped to 3.8% in 2024, a 10.2 - percentage - point decrease from 2017 [5]. - Exports of aluminum products: The scale of China's aluminum product exports to the US has been generally stable, ranging from 350,000 to 600,000 tons, accounting for about 16% of total exports. The indirect export scale of aluminum is estimated to exceed 3 million tons, and exports to the US account for about 15% [7]. - Re - exports of aluminum: After the US trade war in 2017, the global aluminum trade flow was reshaped. China's aluminum exports to the US decreased, while exports to other countries and regions increased. Mexico, Hong Kong and Southeast Asian countries are common re - export destinations [9]. China's Aluminum Consumption and Export Proportion - In 2024, China's full - scale domestic aluminum consumption was 50.23 million tons, accounting for 88% of total consumption, with a compound annual growth rate of 5.3% from 2015 - 2024. Aluminum and aluminum material exports were 6.63 million tons, accounting for 12% of total consumption, with a compound annual growth rate of 4.4% from 2015 - 2024. Exports to the US accounted for about 4.6% - 6.4% of the country's total aluminum product consumption [13]. Impact of Tariff Adjustment - There is some room for enterprises to operate in tariff declaration, but the impact on demand is real. The extent of the impact depends on how the tax is distributed between manufacturers and consumers [14]. - Previous tariff increases made PPI rise but had little impact on CPI, indicating that most of the tariff was absorbed by manufacturers. The specific impact of this tariff expansion needs to be verified by subsequent retail data [14]. - From the perspective of the futures market, this tariff expansion has less impact on aluminum prices. In the medium - term, there are upward drivers for aluminum in September, such as interest rate cuts and the recovery of peak - season demand [16]. Future Focus on Tariff Policy - Future tariff - related content worthy of attention includes global tariff agreements and which categories are within the agreement scope. The US policy uncertainty index has decreased since August 2025 [18].
