US President Donald Trump has signed a decree for a new, globally applicable ten percent tariff on imports into the USA, following a significant defeat in the Supreme Court regarding his previous tariff policies. This new measure, which Trump stated would take effect "almost immediately" and officially from Tuesday at 00:01 local time, is intended to circumvent the Supreme Court's ruling that he exceeded his authority by imposing broad tariffs under an emergency law, asserting that Congress holds sole authority over US trade policy. The White House has outlined numerous exceptions, including pharmaceuticals, automotive products, critical raw materials, fertilizers, and energy supplies, with varying agreements for specific goods depending on the country. Trump is leveraging a 1974 trade law that permits tariffs of up to 15 percent for 150 days, a move that experts question the legal basis for, and which would require Congressional approval by the end of July.
