Classification and labelling
Classification and labelling is crucial for ensuring a high level of protection of health and the environment, as well as for the free movement of substances, mixtures and articles.
Classification and labelling is the starting point for hazard communication and has wider links to other legislation.
Once a substance or mixture is classified, the identified hazards must be communicated to other actors in the supply chain, including consumers. Hazard labelling allows the hazard classification, with labels and safety data sheets, to be communicated to the user of a substance or mixture to alert them about the presence of a hazard and the need to manage the associated risks.
- Always include information on classification and labelling in your registration, regardless of the tonnage band.
- To classify and label your substance , evaluate the intrinsic hazards of the substance using the criteria in the CLP Regulation.
- Carefully check that the harmonised classification reported for your substance is in line with latest update of Annex VI to CLP. Keep in mind that your substance may be a part of a group entry.
- As a general rule, base the classification of your substance containing impurities, additives or multiple constituents (a multi-constituent or UVCB substance) on available relevant information on the substance.
- When you classify for carcinogenic, mutagenic, reprotoxic (CMR) properties or evaluate the bioaccumulation and degradation properties within the hazardous to aquatic environment hazard class, you should normally also base the classification of the substance on information on the known individual constituents.
- If the data on the multi-constituent or UVCB substance shows more severe effects than the data for the single constituents (this may happen for classification for CMR or relevant effects on the bioaccumulation or degradation properties), you should use this more severe data for classification.
- For non-CMR hazard classes, use data from the constituents for classification in accordance with the mixture rules if data on the substance is not available.
- Do not test a multi-constituent substance for classification purposes if there is data on the constituents.
- Under Article 41 of CLP, notifiers and registrants must make every effort to come to an agreed entry for the same substance, and therefore it is normal to update your notifications.
