U.S. Customs and Border Protection announced the suspension of tariff collections imposed under the International Emergency Economic Powers Act (IEEPA), effective Tuesday morning, following a U.S. Supreme Court ruling declaring the duties unlawful. Through an official notice issued to shipping companies via the Cargo Systems Messaging Service (CSMS), the agency confirmed that all tariff codes linked to prior executive orders issued under this law would be deactivated. The decision coincides with the announcement of a new 15% global tariff introduced under a separate legal authority, replacing the duties invalidated by the Court. These developments may impact international trade flows and import costs in the coming period.
