Courier shipments: SOP requires electronic ECM filing, EICI verification, FIFO-linked destuffing permission, and escalation for violations. SOP prescribes that couriers file the Express Cargo Manifest electronically and share it with investigative agencies five hours before arrival; EICI must maintain time-logs, update Form-F1 filings in its internal application, and cross-verify ECM details against Form-01 before issuing a Destuffing Report. Issuance follows FIFO, requires courier requests within two hours of flight arrival and Form-I within one hour, and mandates immediate logging, retrieval, de-stuffing, verification of bag counts, and recording of discrepancies, with escalation to Shift Customs Officers for irregularities.
