Verification of Origin allows importing customs to verify Proof of Origin and request exporting authority confirmation when doubtful. Importing customs may verify the authenticity and veracity of a Proof of Origin or Statement of Origin on random basis or when origin is in doubt; they should first, consistent with domestic law, seek origin-related information from the importer before requesting verification from the exporting Party's competent authority, and must state whether the verification is random or doubt-based and provide detailed grounds when doubt exists. These verification procedures also apply to goods already cleared for home consumption.
