Do you need a TSA password lock to check in the suitcase?

It is suggested that TSA password locks should be installed on the luggage checked in abroad.

The purpose of taking TSA boxes abroad is to avoid the trouble of customs inspection when unpacking. If it is not the customs lock (TSA), the customs will pry the lock hard, and the lock of your box will be broken. If it is a customs lock, use the general TSA customs lock dedicated to the customs to open the suitcase without a simple and rude way.

Customs lock, commonly known as lock, also known as TSA certification lock, refers to the security inspection conducted by the customs on transit luggage and goods and goods under customs supervision. It is necessary to ensure the safety of goods during transportation, and adopt the general TSA special key commonly used by international customs.
