Container lead seal refers to a device similar to a lock applied by a specific person after the goods are loaded into the container and the door is properly closed.
The early lead seal was made of lead, so it is called lead seal, and now it has been updated, with aluminum, iron, plastic, and so on, which is more environmentally friendly and safer. Each seal has a unique number, which is called the seal number. In the short term, this seal number will never be repeated. Customers can judge whether this container has been opened by confirming the seal number. Once the seal is properly locked, it cannot be opened unless it is broken by force (i.e. cut), and the broken seal cannot be used again.
In international logistics, as long as the appearance of the container is complete, the container door is correctly closed, and the lead seal is normally locked, it can be proved that the container is not opened without permission during transportation, and the situation in the box is supervised and responsible for the packing.
