Electronic sealing requirement: exporters must declare RFID seal serials with shipping documentation and use certified vendor systems. Exporters eligible for self-sealing must procure RFID tamper-proof one-time-bolt seals bearing a unique serial and vendor brand, declare the seal's physical serial number with the shipping bill before dispatch, and tag shipment details to the seal via a vendor-supplied web/mobile application that prevents editing. Vendors must certify ISO/RFID conformity, submit seal series to Risk Management Division and ports/ICDs, provide reader-scanners and data transmission to customs at their cost, and integrate their data servers with the customs electronic gateway; customs will verify seal integrity and examine tampered seals.
