How to open the lead seal of tanker? This car often leaks oil. I think I opened the lead seal, but I don't know how. I want to ask how to open it without trace

Do you have a tight key for your lead seal? If not, insert a semi-circular bar at the place where the lead seal is driven, and the lead seal can be opened to ensure that no trace is left. If there is a key, grind it into a triangle at the front with a T-screwdriver, open the tightened key, and then poke it open with a bar.

Lead seal is a lock-like device applied by a specific person after the goods are loaded into the container and the door of the container is closed correctly. Seals can be divided into customs seals, commodity inspection seals and commercial seals according to different personnel. Once the lead seal is locked correctly, it cannot be opened unless it is broken by violence (that is, cut open), and the broken lead seal cannot be reused. Each lead seal has a unique number identification. As long as the container's appearance is complete, the container door is closed correctly and the lead is blocked normally, it can be proved that the container has not been opened in transit, and the situation inside the container is supervised and responsible by the packer when packing.
