In recent years, all countries and regions around the world have strengthened supervision over the safety of imported and exported products. With the development of economic globalization and trade liberalization, trade exchanges among countries around the world have become increasingly frequent, and the safety requirements for imported and exported products have become higher. For instance, goods sold in the European market must meet the CE marking requirements. Goods with the CE marking affixed indicate that they comply with a series of requirements expressed by European directives such as safety, hygiene, environmental protection and consumer protection. For industrial products required to be affixed with the CE marking as stipulated in the relevant directives, those without the CE marking shall not be put on the market for sale. For products that have been affixed with the CE marking and entered the market, if they are found to be non-compliant with safety requirements, they shall be ordered to be withdrawn from the market. Those who continuously violate the relevant provisions of the directives regarding the CE marking will be restricted or prohibited from entering the EU market or forced to exit the market. From this, it can be seen that domestic manufacturers who want to expand into the European market must obtain CE certification. At this time, choosing a suitable CE certification body becomes extremely important
