A high security seal must be affixed to all loaded containers bound for the United States. All seals must meet or exceed the current PAS ISO 17712 standards for high security seals.
Procedures must be in place to verify the physical integrity of the container structure prior to stuffing, to include the reliability of the locking mechanism of the doors. A 7-point checklist or inspection process is recommended for all containers based on the following circumstances:
- Front Wall

- Right Side
- Inside/Outside Doors
Written procedures must also elaborate how seals are to be controlled and affixed to the laden containers, to include procedures for recognizing and reporting compromised seals and/or containers to US Customs and Border Protection (CBP) or the appropriate foreign authority. Only designated employees should distribute container seals for integrity purposes.
Containers must be parked or stored in a secured area to prevent unauthorized access and/or any possible manipulation. Procedures must be in place for reporting and neutralizing unauthorized entry into containers or container storage areas.
