High security seal is also called container seal, which is a padlock used on the container, but it can only be used once. It will break after opening and cannot be used again. There are seals on them, each of which is different. If the number on the container seal received by the customer is the same as on the bill of lading, it means that the container has not been opened and the goods are intact.
Classification of high security seals:
(1) According to the person applying the seal, it can be divided into: factory seal (factory seal, which is added by the export factory); lock (customs seal, which is a customs seal, which is added by the customs); (Added by the company); Temporary seal of the pier (temporary seal of the pier, added by the pier).
(2) According to the material and function of the seal, it can be divided into: high security seal (also known as bullet seal), steel wire seal, plastic seal, blockade, anti-theft lead seal, etc.
When to add a temporary seal to the pier:
(1) accidentally break the seal on the back door of the cabinet when unloading the ship;
(2) After unloading the container in the terminal, the consignee picks up the first shipment.
Precautions:
(1) The name of the operator is printed on the seal of the shipping company (mostly abbreviations. For example, COSCO, MSC, PIL) and a series of Arabic numerals. The seal is usually handed over by the operator to its agent, which is added after the factory has finished the cabinet. The shipping company's seal is usually a bullet seal, which is very strong. When opening the cabinet door, a large iron shear is required to cut it.
(2) Normally, the seal should be added to the right half of the back door. Because the iron piece for pressing the door is welded on the right door (that is, pressing the left on the right), the left door must be closed before closing the right door, and the opposite is true when opening the door. In theory, the four ears of the back door of the cabinet can be sealed.
