Target group

All citizens, organisations and public authorities are welcome to contribute to this consultation.


Period of consultation

From 08.11.2022 to 13.01.2023


Objective of the consultation

The present consultation is carried out in the context of the ongoing review of the Market Definition Notice. The purpose of the consultation is to gather stakeholders’ opinion in relation to the draft revised Market Definition Notice, first rendered public on 8 November 2022.

On 12 July 2021, the European Commission published a staff working document summarising the findings of the evaluation of the Commission’s Market Definition Notice used in EU competition law (OJ C 372, 9.12.1997, p. 5–13, ‘the Notice’).

The Commission published the Notice in 1997 to explain how it applies the concept of relevant product and geographic market in enforcing EU competition law (Art. 101 and 102 of the Treaty on the Functioning of the European Union and in merger control under Council Regulation (EC) No 139/2004). The evaluation – included in the Commission’s 2021 work programme – showed that the Notice remains highly relevant and effective in providing correct, comprehensive and clear guidance on key issues of market definition and the Commission’s approach to it. At the same time, the evaluation also suggested that the Notice does not fully reflect developments in best practices in market definition that have taken place since 1997
