High Security Bolt Seals are constructed of materials such as metal bolt seals or metal cable seals, and designed to prevent intrusion and conform with world customs and ISO security seal standards. ISO is a compliance standard from the US Customs-Trade Partnership Against Terrorism (C-TPAT) and the World Customs Organization’s Framework of standards.
To be classified as a High Security Seal, a seal must have obtained a high security rating per ISO 17712 standard. The ISO 17712 rating provides “uniform procedures for the classification, acceptance, and withdrawal of mechanical freight container seals. It provides a single source of information on mechanical seals which are acceptable for securing freight containers in international commerce.”
Seals that belong to the High Security level are sometimes called "barrier seals". They are made of different metals or metal alloys, meaning they require special tools to be opened, such as bolt cutters or pliers. Cable seals and bolt seals also fall into this category. Designed to deter opportunistic theft of high value goods, they also can often be branded and numbered to improve tamper resistance and provide excellent security for containers.
These steel bolt seals serve as a barrier against theft from trucks and against the hiding and illegal transportation of persons and banned hazardous substances in the containers. Bolt seals can be applied by hand quite easily and quickly. Removing these steel bolt seals requires heavy-duty concrete shears.
Each of our Bolt seals bear a unique number and/or barcode. If a loaded container is delivered at a terminal for export without it bearing such a seal, the terminal staff will apply it. However, they can also decide to embargo the container and to inspect the entire or part of the cargo before applying such a seal. The additional costs involved are payable by the shipping agent or client.
