Determination of origin verification ensures authenticated origin documentation and enables on site inspections for trade compliance. Verification procedure permits the importing Party's customs authority to request authenticity, minimum information, or origin determination checks by presenting the Proof of Origin; questionnaires are routed to the exporting Party's competent authority to obtain information from the Exporter/Producer/Manufacturer/Approved Exporter. Prescribed timeframes apply for authenticity checks, document requests, and substantive origin inquiries, with a possible limited extension by mutual consultation. Further investigative steps can be requested within a fixed period. The importing authority may seek on-site visits to inspect records, production processes and equipment, which the exporting Party must facilitate with accompanying authorities and neutral observers; visits end with a signed Record of Visit detailing the certificate, goods, participants and proceedings.
