Decide on classification and labelling

If your evaluation of the mixture shows that the hazards associated with it meet the criteria for classification in one or more hazard classes, categories or differentiations, you will need to decide on the appropriate physical, health or environmental hazard class, category or differentiation.

After making this decision, you must check which labelling elements correspond to the hazard classifications. The tables in Parts 2 to 5 in Annex I to CLP relate the criteria of each hazard class and category/division with the appropriate classification and labelling elements. Remember to check if a statement, signal word or a pictogram overrules another one. The rules of precedence for these label elements are explained in Chapters 3 to 6 of the Guidance on labelling and packaging.

When you have decided on the classification, you will need to consider what hazard information to give on the label. The label needs to include the following information:

  • supplier details 
  • product identifier
  • nominal quantity
  • hazardous components
  • hazard pictograms 
  • the signal word 
  • hazard statements
  • precautionary statements (usually not more than six unless they are necessary to reflect the nature and the severity of the hazards)
  • supplemental information where relevant.

Label example

 

The obligation to classify and assign the appropriate hazard statements is outlined in Article 13 of the CLP Regulation.

 

Hazard statements

In principle, the label of a product must include all the relevant hazard statements. However, if a substance or mixture is classified within several hazard classes or differentiations of a hazard class, all hazard statements resulting from the classification must appear on the label, unless there is evident duplication or redundancy. This is illustrated in an example in Section 4.1.6 of the Guidance on the application of CLP criteria.

The correct wordings of the hazard statements as they must appear on the label are listed in all languages in Annex III to CLP. You can search for each statement in all EU languages in the Multilingual Chemical Terminology database (ECHA-term).

In addition, there are special rules that concern the labelling of certain mixtures with particular properties. The specific hazards addressed by these rules are indicated on the label using the supplemental EUH-statements. These properties and rules are outlined in Annex II to the CLP Regulation. For example, the presence of lead in a mixture triggers labelling with EUH201 and the possibility that toxic gas might be liberated in contact with water triggers labelling with EUH029. Be careful to identify all relevant EUH-statements, as these are obligatory supplemental information. Even if a mixture is not classified as hazardous, the product may still need to be labelled in accordance with Annex II to CLP, as in the case of sensitising substances (EUH208) or a safety data sheet being available on request (EUH210).

 

Precautionary statements

Product labels must bear the relevant precautionary statements giving advice on how to prevent or minimise the adverse effects to human health or the environment arising from the hazards of a substance or mixture. Precautionary statements must be selected taking into account the hazard statements used, the intended or identified use or uses of the product, and the basic instructions specified in the "conditions for use" columns in tables 6.1 to 6.5 of Annex IV to the CLP Regulation. Duplication and redundancy should be avoided.

When a substance or mixture is supplied to the general public, a precautionary statement addressing the disposal of the product as well as the disposal of the package needs to be included, To keep the labels easy to read and understand, they should contain no more than six precautionary statements. However, if the nature and the severity of the hazards so require, more than six statements can be included.

Information and advice on the selection of the most appropriate precautionary statements is provided in Chapter 7 of the Guidance on labelling and packaging.

The correct wordings of the precautionary statements as they must appear on the label are listed in all languages in Annex III to CLP. You can search for each statement in all EU languages in the Multilingual Chemical Terminology database (ECHA-term).

 

Labelling

Further advice and examples on correct labelling are given in the Guidance on labelling and packaging. For information on the size of the label and the label elements, see Chapter 5.2 of the Guidance.

 

Safety data sheet

A safety data sheet (SDS) must be provided with mixtures classified as hazardous and also at the recipient's request when the mixture contains hazardous substances above certain concentration levels.

When reclassifying a mixture, you need to update the safety data sheet to reflect the new CLP-compliant classification and labelling of your mixture. Is there a substantial change? You must provide the new version of the SDS to your customers. The changes also need to be summarised in the SDS.

The Guidance on the compilation of safety data sheets gives you detailed advice on what is needed to prepare a good safety data sheet.
