On 1 January 2021, the EU REACH Regulation was brought into UK law. This is known as UK REACH. REACH stands for Registration, Evaluation, Authorisation and restriction of CHemicals.

Under the Northern Ireland Protocol the EU REACH Regulation will continue to apply to Northern Ireland after the end of the transition period, while UK REACH will regulate the access of substances to the GB market.

You must ensure that you meet the relevant duties under both UK and EU REACH if your business is supplying or purchasing substances, mixtures or articles to and from:

  • the European Union (EU)
  • the European Economic Area (EEA)
  • Northern Ireland (NI)
  • Great Britain (GB)

There may be actions you need to take to maintain or gain access to these markets.

The role you previously undertook within EU REACH may have changed significantly under UK REACH so it's important to review your role(s).

To find out what your business needs to do to comply with UK REACH, check the Health and Safety Executive (HSE) REACH Guidance
