Making sure your cable seals are C-TPAT compliant

Making sure your cable seals are C-TPAT compliant

The challenges of C-TPAT

The C-TPAT, or Customs-Trade Partnership Against Terrorism, is a supply chain security program focused on fighting terrorism and violations related to the transportation of goods to and from the United States.

This measure was implemented by U.S. Customs and Border Protection in the aftermath of the tragic events of 2001. Since then, all containers must undergo seal procedures to ensure the security and integrity of goods on departure and arrival. Security seals are placed on all containers according to ISO 17712-2013.

Compliant cable seals

There are different types of security seals:

  • Indicative seals are made of metal or plastic, are easy to remove, and are generally used on empty containers being moved short distances;
  • Security and high-security seals are steel or plastic cables designed to prevent tampering and intrusion.

Cable seals must undergo certain tests to ensure their compliance, including tensile strength (greater than 1,000 kg), shear strength (greater than 340 kg), or vertical and lateral impact.

Standardized use

To ensure compliant use, users must keep a detailed log of security seals, maintain security seals regularly, and ensure the seal procedure is carried out properly.

Certain documents are also required to comply with ISO 17712-2013 and to be eligible for the C-TAPT, namely:

    • an appendix to ISO17712-2013 attesting to compliance with the seal procedure;
    • a certificate attesting that the seal complies with security procedures
    • a document from the laboratory that conducted the performance tests.


C-TPAT certification applies to all participants in the supply chain. In addition to using compliant cable seals, the participants must provide complete supporting technical documentation.
