CBP is creating a new module within the ACE system designed to administer IEEPA refund claims.

Importers should get an ACE Secure Data Portal account and importer sub-account, then enrol in the Automated Clearinghouse (ACH) to authorise payment of refunds to a nominated US bank account.

Importers and customs brokers will be able to access the online portal to submit claims, providing lists of affected entry summaries. The system will run automated checks on submitted entries to:

• remove IEEPA‑related HTS provisions
• recompute the duties owed at the time of importation
• carry entries through liquidation or reliquidation as needed
• refund any overpaid IEEPA amounts via electronic payment

CBP has stated that operational, legal, and technical considerations may require adjustments, and the full refund‑processing timeline could extend for several months.
