INSTRUCTIONS, REPORTING THE AFFIXED SEAL NUMBER. To protect cargo interests and to ensure compliance with I.S.P.S. code and Customs-Trade partnership programs (Europe AEO, US C-TPAT), CMA CGM requires the use of high security seals (bolt or cable) that meet or exceed the ISO/PAS 17712:2013 standards.
