In the European Union, EU Regulation 1272/2008 on the classification, labelling and packaging of chemicals and mixtures (CLP) is aligned with the UN GHS system, and mandates industry to self-classify a substance or mixture as soon as new hazardous properties are discovered. The hazard properties of all chemical substances are communicated in a standardised format defined by the Regulation.
The European Chemicals Agency (ECHA) and EU Member States can also propose substances for which it will set a harmonised classification that will then be applicable to packaging, labelling and SDS in all Member States.
Cobalt metal and seven cobalt compounds carry a harmonised classification under the CLP Regulation, and must be packaged and labelled in the EU with (as a minimum) the following classifications:
* Minimum classification

The 2nd Adaptation to Technical Progress (ATP) to the CLP Regulation entered into force in April 2011, and amongst other changes it amended the classification categories for aquatic hazard.
