美媒：特朗普政府正酝酿征收新关税

Core Viewpoint - The U.S. Supreme Court ruled that the large-scale tariffs imposed by the Trump administration under the International Emergency Economic Powers Act were illegal, leading to plans for new tariffs based on national security laws, which may increase economic uncertainty [1][6]. Group 1: New Tariff Investigations - The U.S. Department of Commerce is initiating new investigations under Section 232 of the Trade Expansion Act of 1962 for products in industries such as large batteries, cast iron and iron fittings, plastic pipes, industrial chemicals, and telecommunications equipment [1][6]. - The U.S. Trade Representative's office is also starting new trade investigations under Section 301 of the Trade Act of 1974, which may lead to tariffs on issues like drug pricing and discrimination against U.S. technology companies [2][6]. Group 2: Existing Tariffs and Changes - The Trump administration previously invoked Section 232 to investigate nine categories of products, including semiconductors and solar panels, with many investigations ongoing for nearly a year [2][7]. - There is an intention to modify the algorithm for steel and aluminum tariffs, potentially lowering nominal rates but taxing based on the total value of products rather than just their steel and aluminum content [7]. Group 3: Economic Uncertainty - Following the Supreme Court ruling, the Department of Homeland Security confirmed that tariffs under the International Emergency Economic Powers Act would cease, but tariffs under Sections 232 and 301 remain effective [9]. - The new tariffs announced under Section 122 of the Trade Act of 1974 will impose a 15% tariff on goods from all countries for a maximum of 150 days, requiring Congressional approval for extension [9]. - Experts predict that the complexity and unpredictability of trade policies will increase, leading to greater uncertainty regarding future tariffs [10].
