Tariff Refund Filing for Detroit Entries

The CAPE filing process is the same regardless of port of entry:

  1. Export your ES-003 from ACE (includes entries through Detroit and all other ports)
  2. Upload to Tariffi for automated eligibility analysis
  3. Tariffi prepares the CAPE declaration data for qualifying entries
  4. Your licensed customs broker partner reviews and files via ACE
