The CE mark must be affixed to all new products, whether manufactured in the Member States or in third countries; to used and second-hand products imported from third countries; and to substantially modified products that are subject to directives as new products.
Directives may exclude the application of the CE mark on certain products (specified below), even if the directive otherwise applies to the product. These specific exceptions vary from directive to directive.
The CE mark may not, in principle, be affixed until the conformity assessment procedure has been completed to ensure that the product complies with all the provisions of the relevant directives. This will usually be at the end of the production phase. However, if the CE mark forms an inseparable part of the product, or of a component, for example by stamping or casting, the mark can be affixed at any other stage of the production phase, provided that the conformity of the product is verified as appropriate throughout the production phase.
The CE marking shall, as a rule, be affixed to the product or to its data plate. However, it may instead be affixed to the packaging or to the accompanying documents if:
- affixing the mark is impossible
- it's not possible under reasonable technical or economic conditions, where the minimum dimensions could not be respected
- it could not be ensured that the CE mark was visibly, legibly and indelibly affixed (manufacturers may not do so on purely aesthetic grounds)
The CE mark consists of the letters 'CE', sometimes followed by the identification number of a notified body, as below. The identification number of the NB is added only when that NB has been involved in the production phase of the product.
Sometimes several notified bodies are involved in the production phase, where more than one directive is applicable. In these situations, several identification numbers follow the CE mark.
