The European Chemicals Agency ECHA has published a short guide to the classification and labeling of chemicals in the EU.
The classification, labeling and packaging of hazardous chemicals in the EU is based on a globally agreed system. This facilitates international trade and ensures consistent communication on the hazards posed by chemicals, leading to improved health, safety and environmental protection. Compliance with uniform, globally applicable regulations increases public confidence in the safe use of chemicals.
