Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) regulation at the end of the transition period

At the end of the Transition Period the EU REACH Regulation will be brought into UK law under the European Union (Withdrawal) Act 2018. REACH, and related legislation, will be replicated in the UK with the necessary changes to make it operable in context. The key principles of the EU REACH Regulation will be retained. The independent chemical regulatory framework that will operate in the UK from the 1 January 2021, will be known as UK REACH.

From 1 January 2021 the UK REACH and the EU REACH regulations will operate independently from each other. Companies that are supplying and purchasing substances, mixtures or articles to and from the EU/EEA and the UK will need to ensure that the relevant duties are met under both pieces of legislation.

Implications for business

The role you currently undertake within EU REACH may change under UK REACH, in some cases significantly. It is therefore important that you undertake a review of your role(s) within the EU and UK REACH regimes. To maintain or gain access to the EU/EEA and the UK markets, there may be a number of actions you will need to take.

On 1 September 2020, The Department for Environment Food and Rural Affairs (Defra) published guidance on UK REACH on GOV.UK.

This guidance sets out some of the actions that your company will need to consider so that you can prepare for the end of the Transition Period and comply with UK REACH.  To maintain access to the UK market, there will be transitional provisions in UK REACH to help minimise supply chain disruption and to ensure business continuity. Defra will keep this guidance under review and update it to take account further developments.
