Security seal
One common use is to seal cargo in transit shipping containers in a way that provides tamper evidence and some level of rudimentary security.
These protocols are the official and unofficial procedures used for seal procurement, storage, record keeping, installation, inspection, removal, disposal, reporting, interpreting findings, and training.
Single-use seals are typically made of plastic or metal, and the used material and production technology is the key to their security level.
US Customs-Trade Partnership Against Terrorism (C-TPAT) and the World Customs Organization's Framework of standards, endorsed and encouraged the use of ISO compliant seals.
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.
The C-TPAT[3] (Customs Trade Partnership Against Terrorism) specifies ISO 17712 compliant security seals to be used.
Typical applications include sealing trucks and railway cars transporting valuable commodities.
When the strip is bent and threaded through the hole, a ball inside the housing section locks it in place.
They feature the same types of tamper-evident protection as variable-length and fixed-length have available - numbering, bar-coding, and branding - but fit some different applications.
One reason for this is that plastic padlocks can be placed over a locking part as any metal padlock would be to secure, but do not require keys to open, they simply break off at their built in break point using hands or a small pair of wire cutters.
The transparent body of the seal means that the locking mechanism is visible, and can provide clear indication of tampering.
Meter seals can withstand exposure to sunlight and extreme weather, and a wide range of temperatures.
Typical marking includes logos, special texts, white pads for writing by hand, consecutive numbering, and 1D and 2D bar codes.
The Customs-Trade Partnership Against Terrorism (C-TPAT) is a voluntary supply chain security program led by U.S. Customs and Border Protection (CBP) and focused on improving the security of private companies' supply chains with respect to terrorism.
Large-scale Security Seal producers were included within the "invited foreign manufacturers" segment of the ordinance.
