English translation of American travel guides

The box basically means that if the customs officer (TSA) checks the box when taking it through the customs, the user can temporarily insert any tool into the Z-shaped hole, rotate and open the locked box. As for what TSA is, there is a translation below.

TSA stands for Transportation Security Administration, which means Transportation Security Administration of the United States.

Commonly known as customs lock in China, it refers to the customs' safety inspection of luggage and goods in transit and goods under customs supervision, and the use of general TSA special keys commonly used by international customs to ensure the safety of goods during transportation. It should be noted that China Customs does not have a special key, that is, China Customs will not open the suitcase without the permission of the parties concerned.

TSA customs locks are generally used for boxes used abroad. The customs will open your suitcase for inspection. If there is no TSA customs lock, the customs can't open the suitcase with the general TSA customs lock, so the suitcase will be forced to open the lock on your suitcase by the customs inspector. Therefore, either the customs lock is used, or it is pried open by the customs inspector to destroy the checked baggage lock.
