Export cargo movement by sealed vehicles permits CFS-to-airport transfer under custodian liability and customs verification. Permits transfer of export goods from CFS, Mulund to gateway airport in sealed containers or trucks under customs supervision; the custodian accepts liability for shortages and may execute bonds with FOB debits from a continuity bond. Exporters file shipping bills and documents at CFS for assessment and examination; specified copies are retained, transference copies accompany the goods, seals and seal numbers are endorsed on shipping bills and AR 4, and gateway customs verify seals-broken seals prompt 100% examination while intact seals receive 'shipment allowed' and 'let export' endorsements.
