What is a bolt seal?

Bolt seals are mechanisms used to seal and secure cargo containers, such as shipping containers, trucks and trailers. Bolt seals provide tamper evidence in case of infringement. In this way bolt seals help to detect cargo theft or contamination. These security seals have a relative high breaking strength and therefore also provide some level of security.

A bolt seal used for securing containers must conform to the ISO 17712:2013 high security seal standard in order to be accepted by customs all around the world in ocean shipping. ISO 17712:2013 certified bolt seals also comply with CTPAT. CTPAT, which stands for Customs Trade Partnership Against Terrorism, was started by U.S. Customs and Border Protection to strengthen international supply chains and improve United States border security.

Bolt seals can be applied without the use of tools. This is how you install a bolt seal.

  2. Align the bolt and the bolt lock such that the unique serial part number is visible on both parts.
  3. Coordinate the bolt into the locking mechanism’s hole. Make sure that it is aligned correctly and insert the bolt loosely such that misalignment is avoided.
