Meaning
Disposable security devices that carry unique identification numbers provide a method for verifying that cargo containers remain closed during transit between customs zones. Affixing tracking seals to the locking bars of a shipping container allows logistics managers to detect if the doors were opened before the final destination.
Identifier Permanence
Serial numbers etched into the surface of the hardware prevent the substitution of a legitimate lock with a counterfeit version during the journey. Because tracking seals are logged at both the origin and the destination, any mismatch in the code signals a breach of security.
Border Compliance
China Customs mandates the use of specific security hardware for shipments moving under the internal transit regime. Mandatory tracking seals are inspected by officers at the port of exit to verify that the cargo matches the export declaration. Delays resulting from these checks impact the delivery schedule and increase the storage fees for the exporter who fails to comply.
Security Protocol
Logistics providers must document the application of the hardware in the shipping bill to ensure a clear chain of custody for the cargo. Effective tracking seals prevent unauthorized personnel from adding or removing items while the goods are in a bonded warehouse.
