ECHA CLH registry updated for talc; RAC opinion adopted (Carc. 1B; STOT RE 1) and published

ECHA’s Registry of CLH intentions until outcome for talc (Mg3H2(SiO3)4; CAS 14807-96-6; EC 238-877-9) shows an administrative update dated 2026-02-04 and confirms the CLH process status as “Opinion Adopted.” The entry indicates RAC adopted its opinion on 2024-09-20 and that the RAC opinion was published on 2025-07-09. The RAC opinion supports harmonised classification of talc as Carc. 1B (H350) and STOT RE 1 (H372; lungs; inhalation). This is not yet a legally binding change to CLP Annex VI (no ATP adoption indicated here), but it is a key milestone that compliance teams should track because it can precede an EU Commission ATP that would trigger mandatory classification/labeling and SDS updates for talc and mixtures containing it.
