The CE mark is a self-declaration that the manufacturer's products comply with the corresponding EU directives, including the Low Voltage Directive (LVD: Low Voltage Directive 2014/35/EU), Electromagnetic Compatibility Directive (EMC: Electro Magnetic Compatibility), etc. In order to clearly indicate that the product complies with its Low Voltage Directive, the CE mark must be marked on the product. If the CE mark cannot be marked on the product, it can also be marked on the product packaging, user manual or guarantee (guarantee). The way the manufacturer uses the CE mark to mark the product is to inform the governments of the European Community that his product is legally sold and the product meets the official requirements included in the CE mark. However, the CE mark is not a consumer-recognized mark, but only a recognized mark that the governments of the European Community allow for import.
