The Blue Guide is intended to contribute to a better understanding of EU product legislation and to its more uniform and coherent application across different sectors and throughout the single market. It is addressed to the Member States and to those who need to be informed of the provisions designed to ensure the free circulation of products as well as a high level of protection throughout the European Union

(e.g. trade and consumer associations, standardisation bodies, manufacturers, importers, distributors, conformity assessment bodies and trade unions).

The main differences from version 2014 are about:

- explanations of key concepts of the harmonisation legislation on products
- actors in the product supply chain and their obligations
- product requirements
- conformity assessment
- accreditation
- market surveillance
- explanations of the modules.

The Blue Guide version 2016 is available here.
