Importer duty of care requires documented origin evidence and may trigger compulsory verification of subsequent consignments. Importers claiming preferential duty must retain and furnish prescribed minimum information demonstrating how Rules of Origin criteria, including regional value content and product specific rules, are met; authorities should seek this information from the importer before initiating verification with the exporting country. Submission of a Certificate of Origin does not absolve the importer from exercising reasonable care for accuracy; failure to provide information or exercise reasonable care must be reported to the Risk Management Centre to trigger compulsory verification of subsequent consignments until adequate controls are demonstrated.
