Customs Assigned Importer Number (CAIN)

A Customs Assigned Importer Number (CAIN) is a unique identification number issued by customs authorities to identify and track importers engaged in international trade. The CAIN is used to facilitate customs clearance and compliance with import regulations. Importers must provide their CAIN when filing import declarations, customs documentation, or applications for import permits or licenses. The CAIN allows customs authorities to maintain records of importers, monitor import activities, and ensure that importers meet their regulatory obligations.
