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).
