Origin documentation, declarations, and certificates
What the exam tests
This domain tests proof-of-origin types, data elements, issuance rules, validity, and recordkeeping. You must distinguish certificates of origin, origin declarations, self-certification, approved-exporter declarations, and importer knowledge, and know when each is accepted.
Proof types and controls
A certificate is issued by an authority or approved body; an origin declaration is made on an invoice or other commercial document by an approved or registered exporter; self-certification lets the exporter or importer attest origin subject to registration and audit. Required data usually include exporter and importer, description, HS classification, origin criterion, invoice details, and authorization number. Proof must cover the goods, be valid on the claim date, and support direct transport. Retroactive issuance is allowed only under the agreement's conditions.
Worked example
An exporter issues an origin declaration without the approved-exporter number required by the agreement. The goods qualify substantively, but customs rejects the preference because the proof is not validly issued. A corrected declaration issued within the permitted retroactive period may preserve the claim; a new certificate backdated without authorization does not.
Traps
Treating a certificate as proof of substantive origin; ignoring authorization numbers; missing direct-transport evidence; using an expired or blanket declaration outside its scope; failing to retain supplier records.
