FAQS

What is CE marking & why is it important?

Declaration of conformity issued by the manufacturer or authorized representative, properly executed conformity assessments and product CE marking are the confirmation of product’s safety. CE marking refers to products manufactured in EU member countries and new as well as used products imported to the European market from third countries.

Can a product be CE marked?

CE marking is only permitted when demonstrated that the product meets the essential requirements of directives (having undergone the conformity assessment procedure). Depending on the regulations of the directives and the risk which the product poses, different conformity assessment procedures (modules) are mandatory.

Does Northern Ireland need to affix CE marking?

In particular, the Protocol provides that EU legislation requiring the affixing of the CE marking applies to and in the United Kingdom in respect of Northern Ireland. Contact details for authorities who may be able to help you with CE marking.
