Classification and labelling

Classification and labelling is the starting point for hazard communication and important elements in making sure that human health and the environment are protected from harmful chemicals.

Following the rules of Classification, Labelling and Packaging Regulation is also a prerequisite for free movement of substances, mixtures and articles.

Once a substance or mixture is classified, the identified hazards must be communicated to actors in the supply chain, including consumers.

The label contains information about the identified hazards. The classification, together with a label and an attached safety data sheet, tell the user what hazards are associated with the substance or mixture, and how it is used safely.

 

Keep your classification and labelling up to date

 

  • Always include information on classification and labelling in your registration, regardless of the tonnage band.
  • Evaluate the intrinsic hazards of the substance using the criteria in the CLP Regulation.
  • Check that the harmonised classification reported for your substance is in line with latest update of Annex VI to CLP. Note that your substance may be part of a group entry.

 

 

Classify multi-constituent and UVCB substances correctly
  • When you classify a substance containing impurities, additives or multiple constituents (a multi-constituent or UVCB substance), base the classification 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, 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), use the more severe data for classification.
  • For non-CMR hazard classes, if data is not available on the substance, use data from the constituents for classification according to the mixture rules.

 

 

Update your C&L notification

Article 41 to CLP requires notifiers and registrants to make every effort to come to an agreed entry for the same substance. Changes to notified classifications must be submitted to ECHA within 6 months of the decision to change the classification.
