A manufacturer can only place a product on the EU market when it meets all the applicable requirements. The conformity assessment procedure is carried out before the product can be sold. The European Commission’s main objective is to help ensure that unsafe or otherwise non-compliant products do not find their way to the EU market.

What conformity assessment is

  • A product undergoes a conformity assessment before it is placed on the market
  • It needs to demonstrate that it meets all legislative requirements
  • It includes testing, inspection and certification
  • The applicable product legislation specifies the procedure for each product

Objectives of the conformity assessment procedure

  • To demonstrate that a product being placed on the market complies with all legislative requirements.
  • The procedure should ensure confidence of consumers, public authorities and manufacturers regarding the conformity of products.

How does it work in practice?

  • Product legislation describes the conformity assessment procedures for each product.
  • Manufacturers may choose between different conformity assessment procedures, if applicable.
  • The manufacturer carries out the assessment. The conformity assessment process involves a conformity assessment body if required by the applicable legislation – see notified bodies

Conformity assessment is complementary to market surveillance. Both procedures help ensure the smooth functioning of the internal market.

Declaration of conformity

As part of conformity assessment, the manufacturer or the authorised representative must draw up an declaration of conformity (DoC). The declaration should contain all information to identify:

  • the product
  • the legislation according to which it is issued
  • the manufacturer or the authorised representative
  • the notified body if applicable
  • a reference to harmonised standards or other normative documents, where appropriate

The so-called Blue Guide (2 MB), contains guidance on the application of all aspects of the implementation of EU products rules, including conformity assessments.
