This year marks the first year for the implementation of UK REACH, which entered into force on January 1, 2021. UK REACH maintains EU REACH' s aims and principles, with the necessary changes to make it operable in a domestic context. Transitional provisions were also introduced to reduce post-Brexit trade friction. Under the Northern Ireland Protocol, the EU REACH Regulation continues to apply to Northern Ireland, while UK REACH will regulate the access of substances to the GB market. This means that all existing NI-based EU REACH registrations will remain valid and GB-based EU REACH registrations will no longer be valid in NI.
