The "CE" mark is a safety certification mark that is considered a passport for manufacturers to open and enter the European market. CE stands for Unification of Europe.

In the EU market, the "CE" mark is a mandatory certification mark. Whether it is a product produced by internal enterprises in the EU or products produced in other countries, in order to circulate freely in the EU market, it is necessary to attach the "CE" mark to indicate that the product meets the basic requirements of the EU's "New Methods for Technical Coordination and Standardization" directive. This is a mandatory requirement of EU law for products.
