The CE mark is a mandatory certification mark in the European Union, regarded as a passport for manufacturers to open and enter the European market.
Certificates with a notified body number (NB) are issued by EU-direct notified bodies, and their authority and validity are unquestionable. They can be verified online within the EU.
CE certificates issued by third-party testing agencies are relatively authoritative.
Wireless products exported to Europe require CE RED certification.

The significance of the CE mark lies in indicating that the product bearing it has undergone the corresponding conformity assessment procedures and/or the manufacturer's declaration of conformity, complies with the relevant EU directive provisions, and serves as a permit allowing the product to enter the European Community market for sale. Industrial products required by relevant directives to bear the CE mark cannot be sold without it. Products that have entered the market with the CE mark but are found not to meet safety requirements will be ordered to be withdrawn from the market. Persistent violations of the directive's provisions regarding the CE mark may result in restrictions or prohibitions on entering the EU market or forced withdrawal from the market. The CE mark is not a quality mark; it is a symbol indicating that the product complies with European standards and directives related to safety, health, environmental protection, and hygiene. All products sold in the EU must bear the CE mark mandatorily.
