CE certification is a mandatory conformity mark for products sold within the European Economic Area, indicating they meet EU safety, health, and environmental protection standards. It ensures that a product has undergone the necessary assessments and complies with relevant EU directives or regulations. Manufacturers are responsible for conducting tests, preparing technical documentation, and issuing a Declaration of Conformity before affixing the CE mark. This certification helps create a unified market across Europe, making trade easier and safer. Ultimately, the CE mark builds trust by assuring consumers and authorities that a product is compliant and reliable.
