Container Seals on Maritime Cargo
October 16, 2008 - U.S. Customs and Border Protection are requiring that all containers in transit to the United States must have an ISO/PAS 17712 certified seal. The requirement will take effect on October 15, 2008. However, there will be an informed compliance period before full enforcement goes into effect.
This affects any loaded container that is discharged from a vessel at a U.S. port or remains onboard (FROB) a vessel that arrives at a U.S. port.
The following types of containers are exempt from this regulation:
- Tanks
- Non-standard containers (such as open top)
- Containers that simply cannot accommodate a seal meeting the ISO standard (i.e. custom built containers)
- Empty containers
When a container has been affixed with a seal that meets or exceeds the ISO/PAS 17712 standards, and the shipper wishes to apply a supplementary, additional seal to the container to provide an enhanced level of security, such supplementary seals do not have to meet the ISO/PAS 17712 standards.
Examples of ISO/PAS 17712 seals:
