High Security Rating Barrier Seals-www.gcseals.com
ISO-rated barrier seals are independently tested to meet structural performance standards to earn the "HIGH" security rating. C-TPAT recommends HIGH security seal for cross border shipments.
Ask prospective suppliers of your barrier seals to provide written verification the seal was independently tested to comply with ISO 17712:2013 as a HIGH security seal. To meet the ISO standard, the testing and certificate must be dated within 24 months of your purchase.
A companion latching cable secures the barrier seal to the door latch to minimize tampering with the seal and locking rods on the door. Also, this configuration requires two cuts to remove both the barrier seal and the latching cable, which improves security.
