Bonded air-cargo transshipment permission renews road movement under ECTS seal, subject to bond liability and compliance conditions. Bonded-trucking permission is renewed for export and import air-cargo transshipment from the Air Cargo Complex, Kolkata to Customs-notified airports, Air Cargo Complexes, Container Freight Stations and Inland Container Depots. Cargo must move in closed-body trucks under ECTS seal. The permission operates for three years or until bond expiry, whichever is earlier. Bond amounts are debited on removal of cargo and credited upon delivery to destination Customs. The operator remains liable for cargo shortages or pilferage and must comply with applicable transit, transshipment, cargo-handling and foreign-trade requirements.
