Customs EDI procedures require RMS selection, officer appraisement, and LEO/OOC before ICP cargo exit. The SOP prescribes EDI-based procedures for export, import and transit cargo at ICP Raxaul, requiring compliance with the Customs Act and Handling of Cargo in Customs Areas Regulations. It mandates electronic filing of Shipping Bills, Bills of Entry and EGMs; RMS-based selection, appraisement, registration, duty payment, weighment/examination as directed; and issuance of Let Export Order or Out of Charge prior to exit. Custodian responsibilities include storage, handling, security and indemnity of goods, with removal permitted only on written Customs authorisation. CTD/ECTS seal protocols and inter-agency coordination under Customs control are specified.
