Customs Border Tariff Policy Reset: Supreme Court Blocks IEEPA Duties as Trump Moves to 15% Global Tariffs

A significant shift in U.S. trade policy is underway as the customs border framework undergoes restructuring following a pivotal Supreme Court decision. Tariffs previously imposed under the International Emergency Economic Powers Act (IEEPA) have been ruled illegal by the nation’s highest court, prompting an immediate policy reversal that will reshape cross-border commerce operations.

Supreme Court Invalidates IEEPA-Based Tariffs

The U.S. Supreme Court’s landmark ruling has declared the IEEPA-based tariff regime unlawful, setting in motion a cascading series of administrative changes across federal agencies. This legal determination represents a major setback for the tariff collection apparatus that had been operating under emergency economic powers. The decision effectively terminates the legal authority by which these duties were being levied on imported goods entering U.S. ports.

CBP Deactivates Tariff Codes Starting Tuesday

Following the Supreme Court’s decision, the U.S. Customs and Border Protection agency is taking concrete action to implement the ruling. Beginning Tuesday at 12:01 a.m. Eastern Time (1:01 p.m. UTC+8), CBP will systematically deactivate all tariff codes linked to orders previously issued under the IEEPA framework. The agency communicated this directive to the shipping and import communities through its Cargo Systems Messaging Service, ensuring that shippers and logistics providers understand the timeline for this fundamental shift in duty collection procedures.

New 15% Global Tariff Framework Takes Effect

Rather than leaving tariff policy in limbo, the administration has moved swiftly to establish alternative trade mechanisms. President Trump has authorized a new 15% tariff on global goods under a different legal framework that bypasses the Supreme Court’s objections to emergency economic powers authority. This replacement duty structure goes into effect following the deactivation of the IEEPA tariffs, maintaining continuous tariff policy implementation while operating within legally sanctioned boundaries. The transition from the invalidated framework to this new 15% global tariff regime underscores the ongoing evolution of U.S. customs border policies.
