We do not file refunds. Only you, or the licensed customs broker that filed your entries, can file a CAPE Declaration in ACE. CBP charges no fee. Not a government website; not affiliated with CBP. CBP says: "Do not enter any information into a website other than ACE that claims to process IEEPA refunds." (CSMS 68569567).

Estimated statutory interestEstimated as simple interest from the deposit date to reliquidation; CBP's rate follows 26 U.S.C. 6621 and 6622, which compound daily, so the actual interest is slightly higher (19 CFR 24.36, 24.3a).

Assumptions

  • Interest runs from the deposit date to the date of reliquidation at the overpayment rate CBP publishes each quarter: 7% for non-corporations and 6% for corporations in Q3 and Q4 2026 (CBP notice, 91 FR 60141). The rate follows 26 U.S.C. 6621 and 6622, which compound daily; this calculator uses simple interest, so it slightly under-estimates. — source (2026-10-08)
  • Only entries with IEEPA duties (Chapter 99 headings 9903.01.xx / 9903.02.xx) qualify; Section 232 and 301 duties are not refunded. This estimate does not check eligibility — use the eligibility checker. — source (2026-10-08)
  • CAPE refunds are paid by ACH to the importer of record, generally within 60–90 days of an accepted declaration. — source (2026-10-08)
