The purpose of the Classification, Labelling and Packaging (CLP) Regulation ((EC) No 1272/2008) is to ensure a high level of protection of health and the environment within the EU, as well as the free movement of substances and mixtures. The CLP regulation is based on the United Nations' Globally Harmonized System (GHS). Classification is the starting point for hazard communication and the identified hazards must be communicated to other actors in the supply chain, including consumers and users. A safety data sheet and labelling of a substance/mixture are both necessary and are important tools to communicate with the user of a substance/mixture and to alert them about the presence of a hazard and the need to manage the associated risks.
