The European Union (EU) CLP (Classification, Labelling, and Packaging) Regulation falls under the broader framework of chemical regulation in the European Union. The primary legal basis for the CLP Regulation is Regulation (EC) No 1272/2008.

This regulation, more commonly referred to as the CLP Regulation, aims to align the EU system for the classification, labeling, and packaging of substances and mixtures with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The GHS is a globally recognized system developed by the United Nations to standardize the communication of hazards associated with chemicals.
