promoting the sustainable and responsible use of cobalt in all forms

EU CLP

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:

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.
