       Another name of lead sealing is security seal, which is an obvious tampering mechanism used to seal the goods in transit transport containers in a way that provides tampering evidence and some degree of security. Such a seal can help detect accidental or intentional theft or contamination. Safety seals are usually used to fix truck trailers, logistics vehicles, containers, clothing industry, express logistics, medical products, chemical products, duty-free trolleys of airlines, public utility instruments, etc. Generally, they are considered to be a cheap way to provide tampering evidence for intrusion into sensitive spaces.

Security seals are not intended to address all security issues
      The effectiveness of seals depends to a large extent on the correct method of using them. These agreements are official and unofficial procedures for seal procurement, storage, record keeping, installation, inspection, removal, disposal, reporting, interpretation of results and training. Proper sealing can provide excellent security through good protocols. On the other hand, if you trust it naively, the improper use of complex seals may be worse than useless ones. Downloading electronic lead seals that exist in the market is far safer than ordinary products, which is the best choice at present.

      The same organization has proved that the trained people can defeat 90% of the 244 security seals they studied in less than 3 minutes and all of them in less than 44 minutes using low technology. They provided suggestions on countermeasures and are exploring promising options for the "anti evidence" seal.
Operation mode
Safety seals can be divided into two categories: disposable and reusable.
      Disposable seals are usually made of plastic or metal, and the materials used and production technology are the key to ensure their safety. Reusable seals are usually electronic or mechanical, not only made of plastic. If they are pure plastic, only part of them are reusable. Electronic and mechanical seals are commonly used in the transportation industry. The seals are fixed on the back of trucks, trailers and containers. Reusable mechanical or electronic seals can be installed on the rear door or loading door to extend the cable from itself through the fixed point on the door, generate a unique number when sealing, and record it. This number changes the next time the door is opened, so it provides evidence of tampering for the load.
High Security Seal
      The high security seal is made of metal or metal cable and other materials to delay invasion. Its design conforms to the world customs and ISO security seal standards. The International Standards Organization (ISO) issued a new version of ISO17712 on May 15, 2013. The major changes in the new version involve Article 6, tampering with evidence. Since tests related to tampering proved impractical in ISO 17712:2010, changes were required.
      The measure of seal safety is whether it has obtained ISO 17712:2013 rating. Both the U.S. Customs Anti Terrorism Trade Partnership (C-TPAT) and the WCO standard framework recognize and encourage the use of seals that meet ISO standards.
Some safety level requirements for seals are defined in ISO 17712. Seals belonging to high security level and security level are also called "barrier seals". They are made of different metals or metal alloys, which means they need to open special tools, such as wire cutters or pliers. Cable seals and bolt seals also fall into this category. Designed to prevent opportunistic theft of high-value goods, they can also be labeled with trademarks and numbers to improve tamper resistance and provide excellent security for containers. Seals conforming to the class indicated in ISO 17712 are made of plastic or thin metal.
      The safety seal manufacturer, together with the ISO safety auditor, provided the following information to help enterprises and other relevant parties understand the new version.
Customs seal
      The seals accepted by the customs are the security seals that will be accepted by the customs department of the designated country/region as the security seals placed on the container. This does not mean that all exporters or importers should affix seals approved by Shanghai Customs on their containers or trailers. Many enterprises that transport high-value goods prefer to use seals recognized by the customs because these seals have been strictly tested and have high quality.
