United States: CBP Preparing IEEPA Tariff Refund Process in ACE

In a court filing on March 6, 2026, U.S. Customs and Border Protection (CBP) informed the Court of International Trade (CIT) that it was developing functionality in the Automated Commercial Environment (ACE) to process CIT ordered refunds of the International Emergency Economic Powers Act (IEEPA) within the next 45 days. Brandon Lord, the executive director of trade programs at CBP, stated in the filing that “CBP is confident that it can develop and implement new ACE functionality that will streamline and consolidate refunds and interest payments on an importer basis, rather than issuing 53,173,939 separate entry-specific refunds with multiple payments going to the same importer.”

While “operational, legal, and technical considerations” may impact the final process, CBP anticipates that refund process will involve:

  • Importer filing a declaration in ACE that includes a list of entries in which IEEPA duties were paid.
  • ACE runs a validation query on the entries in the query and re-calculates the duty owed without IEEPA.
  • CBP verifies the declaration and processes refunds.
  • ACE automatically finalizes the entry (liquidates or reliquidates).
  • ACE automatically aggregates the refunds with interest by importer and liquidation date.
  • Refund is certified by CBP.
  • The Treasury Department issues the refund electronically.

United State: CIT Orders CBP to Refund IEEPA Tariffs

In an order filed on March 4, 2026, the Court of International Trade (CIT) directed U.S. Customs and Border Protection (CBP) to liquidate all unliquidated entries subject to International Emergency Economic Powers Act IEEPA tariffs “without regard to the IEEPA duties.” In addition, “any liquidated entries for which liquidation is not final shall be reliquidated without regard to IEEPA duties.” The order contained no timeline or process for these refunds.

24 U.S. States File Suit Against Section 122 Tariffs - CIT Rules IEEPA Tariffs Unlawful, Orders Refunds for Importers

In a complaint filed on March 5, 2026, 24 U.S. States asked the Court of International Trade (CIT) to declare the Section 122 tariffs as “unlawful” and to “declare that they are not in force, enjoin the Defendant agencies and officers from enforcing them, and vacate the agency actions implementing them.” In a significant but incomplete initial win for importers, Judge Eaton of the Court of International Trade (CIT) declared the IEEPA tariffs void ab initio, which means “unlawful from the start.” He ordered that:

  • Unliquidated entries (which are the bulk of recent filings) must be refunded.
  • “Not finally liquidated entries” (meaning entries liquidated in the last 90 days) must be refunded.
  • Interest must be paid on refunds.
  • Finally, liquidated entries, as well as refunds for importers that are not current litigants with the CIT, will be discussed Friday, March 6 in a non-public conference.

Based on the Judge’s wording, the order may not require individual litigation or even Post Summary Corrections (PSCs) to trigger a refund, though this remains subject to CBP implementation and appellate review.
