Supreme Court Strikes Down IEEPA Tariffs: What Importers Need to Know About Refunds

The U.S. Supreme Court ruled 6–3 that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) are unlawful, holding that the President lacks authority to impose broad-based tariffs without clear congressional approval. With approximately $175 billion collected under these now-invalid tariffs, the government could face substantial refund exposure. Importers should begin reviewing their entries now, as refund procedures have not yet been announced.
