Customs declaration

A customs declaration is the formal filing with a country's customs authority to declare imported goods. In the U.S. it is CBP Form 7501 (Entry Summary); in the EU, the Single Administrative Document (SAD).

U.S. entries are filed electronically through ACE (Automated Commercial Environment). The Entry Summary captures HTSUS classification, declared value, country of origin, importer of record, duty calculation, and any special-trade-program claims.

Most importers file through a licensed customs broker. The broker is the regulated entity that signs the declaration; the importer of record is the legal party responsible for duty payment and compliance.

Declarations are subject to audit. CBP can issue a Request for Information (CF-28) or a Notice of Action (CF-29) months after entry, and back duties plus penalties apply if the original filing was incorrect.
