COMMISSION NOTICE The ‘Blue Guide’ on the implementation of EU product rules 2022 · European Union

The CE marking replaces all mandatory conformity markings having the same meaning, which existed before harmonisation took place. Such national conformity markings are incompatible with CE marking and would constitute an infringement of the applicable European legislation in question. When transposing Union harmonisation legislation, Member States are required to incorporate the CE marking into their national regulations and administrative procedures. They must also refrain from introducing any other conformity marking into their national legislation that has the same meaning as the CE marking.
