Export container movement controls require CFSs to secure bonds, indemnities and documentation before port entry. Custodians/Cargo Service Providers must execute a bond equal to ten percent of prior-month export value with a bank guarantee, provide an indemnity bond, and maintain mandatory real-time soft records of shipment details. After meeting these conditions and obtaining an NOC from the Enquiry Unit, only approved CFSs may move export-laden containers to the Chennai Port; movement requires completion of verification, examination and issuance of Let Export Order at the CFS and adherence to documentary requirements before scheduling transfers to the Port.
