Adopted opinions and previous consultations on applications for authorisation

This page provides further information on the applications for authorisation or review reports, which have undergone consultation. The applications for authorisation are in the opinion development phase until the final opinions of the Committees for Risk Assessment and Socio-economic Analysis have been adopted and sent to the European Commission. Its decision-making process can be followed through the comitology register, where further information is published about the REACH Committee's past and upcoming meetings.

On 1 February 2020, the United Kingdom (UK) withdrew from the EU. The transition period provided by the withdrawal agreement ended on 31 December 2020. As of 1 January 2021, an application for an authorisation submitted by a person established in the UK (except Northern Ireland) is no longer valid in the EU, unless that application has been transferred to a legal entity established in the EU or Northern Ireland before the end of the transition period. Therefore, authorisation applications and decisions in so far as these concern persons established in the UK (except Northern Ireland) are no longer considered valid.
