Express Cargo Clearance: automated ECM/CBE filing, risk based screening and online duty payment enabling phased courier terminal automation. Implementation of an automated Express Cargo Clearance System (ECCS) creates a phased, web based framework for electronic ECM and CBE filing, access controlled user roles, barcode arrival scanning and weight verification, digital signatures with physical signing when Service Center staff file, and integrated online payment. ECCS prescribes RMS based self assessment, X ray screening, inspection and assessment workflows, provisional assessment on bond with bond master and registration functions, ECM/CBE amendment constraints tied to IGM feed and arrival scan, hold and warehouse procedures, stop/cancellation/amendment before Out of Charge, and limited manual clearance only for exceptional downtime.
