New standards for high security seals will go into effect on May 15, 2014. C-TPAT requires high security seals to meet or exceed PAS ISO 17712:13 standards, although C-TPAT certified partners can continue to use container seals that meet PAS ISO 17712:10 standards until their stock is depleted.

C-TPAT certified partners must advise their business associates of the new container seal requirements to ensure they continue to meet the C-TPAT criteria for seal standards.

All parties who purchase container seals should request conformance certificates provided by an accredited independent lab prior to purchase, as proof that the seals meet PAS ISO 17712:13 standards.
