Know Your Customer requirements mandate KYC documentation for shipping lines and freight forwarders including ID, address, IEC, and authorisations. Know Your Customer norms require shipping lines, container lines, agents/sub-agents and freight forwarders to collect photo identity, address proof, IEC copies, and letters of authority from persons booking containers; freight forwarders must additionally supply registration, employee letters of authority where applicable, and a declaration confirming collection of mandated documents. Compliance for recurring, unchanged transactions remains valid for a subsequent period. The same requirements apply mutatis mutandis to imports.
