On March 16, 2026, the European Chemicals Agency (ECHA) opened public consultations on proposed updates to the harmonised classification and labelling (CLH) of certain substances under the EU Classification, Labelling and Packaging (CLP) Regulation. The proposals, submitted by Latvia and Austria, seek to revise hazard classifications for 1. hydrochloric acid 2. sulphuryl difluoride The updates include additional or stricter classifications related to acute toxicity, corrosivity, environmental hazards, and specific target organ toxicity, reflecting new scientific evidence and risk assessments. The consultation process allows stakeholders to submit scientific data, comments, and evidence on hazard classes under review. The consultation period runs until May 18, 2026, after which the Risk Assessment Committee (RAC) will evaluate the input and adopt an opinion. These updates aim to ensure accurate hazard communication, improve chemical safety, and support regulatory decision-making across the European Union.
