Certificate of Origin
Category: Documents
Definition (plain English)
A certificate or supplier declaration used to show where goods originate for customs, preference, buyer, or regulatory purposes.
Why it matters commercially
Origin evidence can change duty rates, unlock or invalidate preference claims, and determine whether customs accepts the declared treatment.
Example
An importer claimed preferential duty only after the supplier provided a certificate of origin backed by bill-of-material and production records.
Common mistake
Treating any origin certificate as automatic proof of preference without checking the trade agreement rule and supporting records.
