被判违法后，特朗普为何能宣布额外征收10%全球关税？还有牌？

Core Viewpoint - The Trump administration is planning to impose an additional 10% tariff on global goods based on the Trade Act of 1974, Section 122, following a Supreme Court ruling that deemed previous tariff policies illegal [1][4]. Group 1: Tariff Implementation - The additional 10% tariff will be implemented immediately, as stated by U.S. Trade Representative Lighthizer [1]. - The Section 122 allows the U.S. government to impose tariffs of up to 15% within 150 days, with the possibility of further investigations into specific industries [2][4]. - The administration is facing pressure to act due to existing trade agreements that could create disparities in tariff rates between countries with agreements and those without [4]. Group 2: Legal Framework and Options - The Trump administration has several legal avenues for imposing tariffs, including Sections 232, 301, and 201 of the Trade Act, as well as Section 338 of the Tariff Act of 1930 [1][6]. - Section 232 has already been used for tariffs on steel and aluminum, while Section 301 investigations are ongoing against countries like Brazil [6][7]. - Section 201 is a more traditional safeguard mechanism that allows for tariffs based on injury to domestic industries, with historical rates ranging from 30% to 50% [7]. Group 3: Economic Implications - The Treasury Secretary indicated that the use of Section 122 and potential enhancements of Sections 232 and 301 could maintain U.S. tariff revenue levels through 2026 [4]. - Experts suggest that tariffs are politically unpopular due to their impact on price levels and consumer affordability [5][6]. - There is a concern that the administration may exploit the legal framework to repeatedly implement Section 122 without clear prohibitions against such actions [5].
