UK Alliance of Chemical Associations Highlights Concerns Over UK REACH ATRm

In April–May 2026 the UK Alliance of Chemical Associations sent a joint letter, published by UKCPI, warning that the Government’s UK REACH Alternative Transitional Registration model (ATRm) still creates costly, duplicative registration burdens and compressed deadlines despite planned alignment with EU REACH. The letter signals strong industry pressure on Defra and DBT to recognise EU registrations, allow wider use of public ECHA data, and revisit ATRm timelines and data requirements, which could shape subsequent UK REACH implementation and compliance planning for UK and EU supply chains.

Alliance Of Chemical Associations Criticises UK REACH ATRm Response And Urges Recognition Of EU REACH Registrations

DEFRA’s new ATRm approach under UK REACH reduces upfront data requirements for transitional registrations while keeping the no data, no market principle and signalling closer alignment with EU decisions, but the legal details and extended deadlines still demand careful planning from GB registrants. ACA’s response highlights the remaining £500m-plus cost burden, duplicate UK/EU registrations, and compressed 12-month windows to meet the 2029–2031 transitional deadlines, making it a critical signal that companies should reassess their UK REACH strategy, data access arrangements, and resource planning.

HSE Proposes GB Mandatory Classification of Bisphenol F as Repr. 1B (H360F)

In March 2026 the UK Health and Safety Executive issued an Agency Opinion proposing a GB mandatory classification of bisphenol F (CAS 620-92-8) as Reproductive toxicity Category 1B with hazard statement H360F under the GB CLP Regulation. This aligns GB with EU and Northern Ireland, modestly increases COSHH-driven workplace duties, and creates a clear trigger for potential future UK REACH Annex 17 restrictions and SVHC authorisation decisions on bisphenol F, even though current UK and EEA use appears limited.
