Yet, many companies overlook key factors when selecting or managing their seals — leading to costly security lapses and compliance failures.
In this article, we’ll discuss the most common mistakes businesses make with security seals and how to avoid them through better practices and compliance awareness.

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