Freight forwarders and customs agents filing transit declarations in NCTS typically act as the principal – the party that assumes full legal responsibility towards customs for the correct completion of the transit procedure. The principal lodges the required transit security, usually as an individual guarantee, comprehensive guarantee, or cash deposit, and is liable for any customs debt arising from irregularities. They are the primary contact for customs authorities on questions of cargo description, destination, and compliance with transit conditions. Unlike the carrier, who moves the goods physically, the principal bears primary legal liability; submitting the declaration confirms the accuracy and completeness of all data provided.
