税率50%，美国将407类钢铝衍生产品纳入关税清单

Core Viewpoint - The U.S. Department of Commerce has expanded the steel and aluminum tariff list to include 407 product categories, imposing a 50% tariff rate, aimed at protecting domestic manufacturing and reducing import dependency [1][2]. Group 1: Tariff Expansion Details - The new tariffs, effective from August 19, significantly broaden the scope of previous tariffs announced by the Trump administration, now covering a wide range of products including wind turbines, mobile cranes, railway vehicles, furniture, and various machinery that contain steel or aluminum components [2]. - The Department of Commerce's action is intended to close loopholes and continue revitalizing the U.S. steel and aluminum industries, as stated by Jeffrey Kessler, Deputy Assistant Secretary for Industry and Security [2]. Group 2: Economic Impact - Experts warn that the new tariffs could affect at least $320 billion worth of imports based on 2024 projections, potentially exacerbating cost-push inflation as indicated by the rising Producer Price Index (PPI) [3]. - Importers face a dilemma as many goods are already in transit; accepting the goods will incur high tariffs, while delaying delivery could lead to significant financial losses [3]. Group 3: Historical Context - In June, the Trump administration announced a doubling of steel and aluminum import tariffs to 50%, which has already caused disruptions in global supply chains [4].
