Lead seals are products made from lead materials. The most common ones are lead seals installed on electric meters and water meters. They can also be called lead seals. However, the seal is a toxic product because it contains a lot of lead.

There are many names about instruments in the market, such as instrument seals, instrument seals, instrument seals, plastic seals, and so on. The most appropriate name should be the meter seal. A professionally produced lead seal is a device similar to a lock applied by a specific person after the cargo is loaded into the container and the door is properly closed.

Seals can be divided into different categories depending on the person being applied, such as customs seals, commodity inspection seals and commercial seals. After the seal is locked, it is generally not allowed to open arbitrarily. There is only a unique number on each seal. In the case of a complete appearance of the container, the container door is properly closed, and the seal is normally locked, it can be proved that the container has not been opened privately during transportation, and the condition of the container is supervised by the packer at the time of packing. In particular, the customs seal is to be legally liable if it is taken apart.
