European Conformity: CE Marking Under European Economic Area

CE stands for "Conformité Européenne," which translates to "European Conformity" in English. It is a mandatory conformity marking required for products sold within the European Economic Area (EEA), which includes the member states of the European Union (EU), as well as Iceland, Liechtenstein, and Norway.

The obligation of CE marking arises from EU legislation, which mandates that certain products meet specific health, safety, and environmental protection requirements before they can be placed on the market within the EEA. These requirements vary depending on the type of product and are outlined in relevant EU directives and regulations.


Manufacturers: Manufacturers play a pivotal role in ensuring product safety within the EEA market. Their responsibilities include conducting thorough assessments to ensure compliance, preparing technical documentation, issuing the EU declaration of conformity, and affixing the CE marking onto the product.
For manufacturers, the obligation of CE marking involves conducting a conformity assessment to demonstrate that their products comply with the applicable EU requirements. This typically includes:
  1. Identifying the relevant EU directives or regulations that apply to the product.
  2. Ensuring that the product meets the essential requirements set out in those directives or regulations.
  3. Carrying out conformity assessment procedures, which may involve testing, documentation, and quality control measures.
  4. Compiling a technical file containing all relevant information about the product's design, manufacturing process, and compliance with EU requirements.
  5. Issuing a declaration of conformity stating that the product meets the applicable EU standards.
  6. Affixing the CE marking to the product, packaging, or accompanying documentation to indicate compliance with EU regulations.
