The letters ‘CE’ appear on many products in the EU.
CE stands for the French ‘Conformité Européenne’, which translates to ‘European Compliance’. Manufacturers of products with the CE-marking declare that the products meet high safety, health and environmental protection requirements in response to EU legislation.
