CE certification is a model that meets the European requirements of 'Conformity of Europe', also known as European Conformity (EC). The "CE" mark is a safety certification mark that is considered a passport for manufacturers to open and enter the European market. The "CE" mark is a mandatory certification mark in the EU market. Products with the "CE" mark can be sold in various EU member states without meeting the requirements of each member state, thus achieving free circulation of goods within the EU member states. CE is the most basic requirement for product safety, health, and environmental protection in the European Union, not a quality requirement.
