We are firmly committed to full compliance with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and the BPR (Biocidal Products Regulations) — the regulatory frameworks that govern our sector. Meeting all current requirements is not a box-ticking exercise; it is central to how we operate.
