CBP Form 5106, also known as the Importer Identity Form, is required by U.S. Customs and Border Protection before any formal import entry can be processed in the United States. Filing establishes your Importer of Record number within CBP's Automated Commercial Environment, which is used to identify your business across all customs transactions, duty assessments, and refund issuances.
Importers seeking IEEPA tariff refunds through the ACE Secure Data Portal must have an active Form 5106 on file before portal access is granted. Without a current registration, refund claims cannot be submitted and shipment clearance may be delayed.
Whether you are importing goods for the first time, reactivating an inactive importer number, or updating existing information on file with CBP, the process begins with submitting a complete and accurate Form 5106. Errors, missing information, or an incorrect submission address are among the most common causes of processing delays.
New importer records are typically processed by CBP within 2 business days of receiving a complete submission. Updates to existing records may take up to 5 business days.
