The "CE" mark is a safety certification mark that is regarded as a passport for manufacturers to open and enter the European market. All products bearing the "CE" mark can be sold in each EU member state without having to meet the requirements of each member state, thus achieving the free circulation of goods within the EU member states.

In the EU market, the "CE" mark is a compulsory certification mark. Whether it is a product produced by an enterprise within the EU or a product produced in other countries, if it wants to circulate freely in the EU market, it must be affixed with " CE" mark to indicate that the product complies with the basic requirements of the EU's "New Approach to Technical Coordination and Standardization" directive. This is a mandatory requirement imposed by EU law on products.

The word CE is abbreviated from the French "CommunateEuroppene", which means European Community. The European Union later evolved into the European Union (EU for short).

In recent years, more and more products are sold in the market of the European Economic Area (European Union, European Free Trade Association member states, except Switzerland). The CE mark is used more and more. It means that it meets the requirements expressed by a series of European directives such as safety, health, environmental protection and consumer protection.

In the past, European countries had different requirements for imported and sold products. Goods manufactured according to one country’s standards would most likely not be available in other countries. As part of efforts to eliminate trade barriers, CE came into being. Therefore, CE stands for European unity (CONFORMITEEUROPEENNE). In fact, CE is also the abbreviation of the phrase "EUROPEAN COMMUNITY" in many European languages. Originally, the English phrase EUROPEAN COMMUNITY was abbreviated as EC. Later, EUROPEAN COMMUNITY was COMMUNATEEUROPEIA in French. , Italian is COMUNITAEUROPEA, Portuguese is COMUNIDADEEUROPEIA, Spanish is COMUNIDADEEUROPE, etc., so EC is changed to CE. Of course, you might as well regard CE as CONFORMITYWITHEUROPEAN (DEMAND) (in line with European (requirements)).

The significance of the CE mark is: using the CE abbreviation as a symbol to indicate that the product with the CE mark complies with the main requirements (Essential Requirements) stipulated in the relevant European directives, and is used to confirm that the product has passed the corresponding qualifications The assessment procedure and/or the manufacturer's declaration of conformity truly become the passport for the product to be allowed to enter the European market for sale. The relevant directive requires industrial products to be affixed with the CE mark. If they do not have the CE mark, they shall not be put on the market for sale. If the products that have been affixed with the CE mark and enter the market are found to not meet the safety requirements, they shall be ordered to be withdrawn from the market. If they continue to violate the directive's provisions on the CE mark, will be restricted or prohibited from entering the EU market or forced to withdraw from the market
