ECHA Opens Public Consultation on Harmonized Classification and Labelling (CLH) Proposals for 1 Substance

On November 3, 2025, the European Chemicals Agency (ECHA) solicited public comments on the harmonized classification and labeling (CLH) proposals for a substance, with a consultation period of 60 days.

Name	EC Number	CAS Number	Hazard classes open for commenting	Start of consultation	Deadline for consultation
propaquizafop (ISO); 2-[(isopropylideneamino)oxy]ethyl (2R)-2-{4-[(6-chloroquinoxalin-2-yl)oxy]phenoxy}propanoate	-	111479-05-1	Explosives Flammable solids Self-reactive substances and mixtures Self-heating substances or mixtures Substances or mixtures which in contact with water emit flammable gases Oxidising solids Acute toxicity – inhalation Acute toxicity – dermal Acute Toxicity - oral Skin corrosion/irritation Serious eye damage/eye irritation Skin sensitisation Germ cell mutagenicity Carcinogenicity Reproductive toxicity Specific target organ toxicity — single exposure Specific target organ toxicity — repeated exposure Hazardous to the aquatic environment	03/11/2025	02/01/2026

The CLH process aims to ensure consistency and transparency in hazard information for chemicals across Europe. This procedure involves assessing the hazardous properties of chemical substances, proposing appropriate classifications and labels, collecting public input, and concluding with a final review and recommendations by ECHA's Committee for Risk Assessment (RAC).
