Many businesses still use seals that don’t comply with ISO or C-TPAT standards, making shipments vulnerable to customs rejection.
Common Mistake:
Failing to ensure seals are ISO 17712:2013-certified for global cargo shipments.
How to Avoid
A seal is only useful if its unique serial number is accurately recorded. Without proper documentation, tampering can go unnoticed.
Common Mistake:
Seal numbers are written incorrectly, duplicated, or not recorded at all.
How to Avoid
Seals are single-use devices designed to provide tamper evidence. Reusing or storing them carelessly weakens their security.
Common Mistake:
Reusing seals from old shipments or storing them in high humidity areas that degrade their integrity.

How to Properly Apply & Remove Security Seals without Causing Damage
Seals used in extreme weather — heat, cold, or salt air — can degrade faster if not made from suitable materials.
Common Mistake:

Common Mistake:
Opting for cheap, unbranded seals with no certification or testing.
