The CLP Regulation[1] (for "Classification, Labelling and Packaging"[2]) is a European Union regulation from 2008, which aligns the European Union system of classification, labelling and packaging of chemical substances and mixtures to the Globally Harmonised System (GHS).

It is expected to facilitate global trade and the harmonised communication of hazard information of chemicals and to promote regulatory efficiency.

It introduced new classification criteria, European hazard symbols (pictograms) and Risk and Safety Statements for labelling, while taking into account elements which were part of the prior EU legislation.

The regulation requires companies to appropriately classify, label and package their substances and mixtures before placing them on the market.

Classification and labelling is harmonised to ensure an adequate risk management for hazards of highest concern (carcinogenicity, mutagenicity, reproductive toxicity (CMR) and respiratory sensitisers) and for other substances on a case-by-case basis.
