C-TPAT and ISO 17712 Compliant Seals

C-TPAT Compliant High-Security Seals for Containers and Cargo

COMMON APPLICATIONS: airlines, Canadian manufacturers, freight, logistics, Mexican manufacturers, shipping, supply chain, third-party logistics (3PL) providers, and transportation.

C-TPAT compliant high-security seals are used to secure shipping containers and cargo in international supply chains while supporting Customs-Trade Partnership Against Terrorism (C-TPAT) security requirements. Companies participating in the C-TPAT program must implement strict cargo security procedures, including the use of ISO 17712 certified seals that provide tamper-evident protection for containers and trailers transporting goods across global trade routes.

High-security bolt seals and cable seals are commonly used to secure ocean containers, truck trailers, and intermodal cargo. Once applied, these seals create a clear visual indicator if a container has been opened or compromised during transit. Each seal includes a unique serial number that can be recorded on shipping documentation and verified throughout the shipment’s chain of custody.

Using C-TPAT compliant security seals helps organizations strengthen supply chain security, maintain cargo integrity, and support compliance with U.S. Customs and Border Protection requirements.
