Section 122 Announcement
Trump announces intent to use the Trade Act of 1974 to set a 15% global tariff floor.
The Trump administration will maintain existing China tariffs between 35% and 50% to ensure market continuity following a Supreme Court ruling that invalidated previous legal justifications. US Trade Representative Jamieson Greer confirmed the move as a strategic baseline ahead of a high-stakes summit between President Trump and President Xi Jinping.
President Trump has signed an executive order imposing a 10% global tariff by invoking Section 122 of the Trade Act of 1974, following a landmark Supreme Court ruling that invalidated his previous use of emergency powers. The move recalibrates trade relations with key partners like India while setting up a new 150-day window of economic uncertainty.
