Do customs declarers need certificates? Why do you see that many companies don't necessarily need a customs broker's card for recruitment?

A customs broker's card is a written document to prove the customs broker, just like a driver's license to prove the driver. There are many possibilities for handling customs declaration certificates, most of which are mainly to entrust the customs declaration business to freight forwarders or customs declaration banks that have not declared customs.

Answer your second question.

The difference between customs declarers and customs declarers is that customs declaration is aimed at customs, and inspection declaration is aimed at entry-exit inspection and quarantine. At present, two different departments are more popular with double certificates, that is, the customs declaration certificate and the newspaper verification are tested together. There is no connection between the two certificates, but there will be a lot of knowledge intertwined in specific work, and the current order of customs clearance is "prior declaration", so it will be even more awesome if a person masters both skills at the same time.
