Supreme Court Invalidates IEEPA Tariffs
March 16, 2026
The U.S. Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA) does not authorize the president to impose tariffs, invalidating a broad set of tariffs previously applied under this authority. Following this decision, the U.S. Court of International Trade (CIT) ordered U.S. Customs and Border Protection (CBP) to refund or reliquidate these unlawful tariffs, potentially resulting in billions of dollars in refunds to importers, including government contractors. However, the refund process is complex and delayed due to the volume of entries involved and the administrative challenges of implementing an efficient refund framework within CBP's Automated Commercial Environment (ACE).
Government contractors with fixed-price contracts may need to adjust contract prices to reflect tariff refunds, while those with cost-reimbursement contracts are generally required to credit refunded tariffs back to the government. Contractors should carefully assess their import entries, contract terms, and consider filing claims or protests to recover tariff payments. The evolving legal and administrative landscape requires close attention to ensure proper financial adjustments and compliance.
- Why this matters: Government contractors impacted by IEEPA tariffs face potential financial recoveries and contract price adjustments that could affect project budgets and invoicing.
- The refund process involves significant administrative complexity, with CBP managing over 53 million entries, indicating potential delays and the need for proactive claims management.
- Contractors should evaluate contract types (fixed-price vs. cost-reimbursement) to determine appropriate financial treatment of tariff refunds.
- Legal counsel and trade experts may be necessary to navigate claims, protests, and compliance with CIT rulings and CBP procedures.
Refunding or reliquidating more than 53 million entries would be time-consuming and difficult, and implementing a framework within ACE to process refunds efficiently would require additional time.

It is not our position that every single entry and every importer will get a refund. Our position is that you have to file a claim in this court which is why over 2,000 companies have filed claims.
— Government representative before the U.S. Court of International Trade
All importers of record whose entries were subject to IEEPA duties are entitled to benefit from the Supreme Court's ruling, not just the plaintiffs in the underlying litigation.
— Judge Richard K. Eaton, U.S. Court of International Trade
