Customs operational procedure at the new air cargo complex ensures dual-site services, document rules, and preserved first-check protocol. Customs operations will function concurrently at the new and existing air cargo complexes with Service Centre, banking, and document-generation facilities available at both sites; electronic filing via ICEGATE and trade-facility systems continue unchanged. Importers/CHAs must keep a set of documents at each site; originals accompany the Customs copy of the Bill of Entry at the shed while photocopies or faxed copies may be accepted for verification. The first check procedure is retained for FOC goods with online shed approvals; Chartered Engineer certificates and other authorisations may be assessed on photocopies though originals are to be submitted to the shed. Re-imports require original Bills for verification. ATA Carnet imports require verification of guarantees and separate registers; procedures apply immediately until further orders.
