U.S. Customs and Border Protection (CBP) announced it will stop collecting tariffs imposed under the International Emergency Economic Powers Act (IEEPA) at 12:01 a.m. ET on February 24 after the U.S. Supreme Court ruled the tariffs illegal. The decision ends enforcement of the emergency-based tariff framework at the border. At the same time, new 15% global tariffs are being introduced under separate legal authority, indicating a shift in the statutory basis for U.S. trade measures rather than a full rollback of tariff policy.
