ECHA notes PFHxA, its salts and related substances REACH restriction starts in April 2026

ECHA’s PFAS hot-topics page highlights an upcoming compliance horizon: restrictions for undecafluorohexanoic acid (PFHxA), its salts and related substances will start applying in April 2026 in the EU/EEA. Compliance teams should use this as a planning trigger to review product portfolios and supply chains for PFHxA-related substances and ensure readiness for EU restriction applicability, including substitution, supplier declarations, and potential reformulation timelines. (The research text does not provide a specific day in April 2026, so no implementation date is recorded.)
