Requirements of labelling in accordance with the CLP Regulation

The CLP Regulation requires that the labels are firmly affixed to one or more surfaces of the immediate container of the substance or mixture and that they must be readable horizontally when the package is set down normally.

The label elements themselves, in particular the hazard pictograms, must stand out clearly from the background. Furthermore, all label elements must be of such size and spacing as to be easily read. They must be clearly and indelibly marked. A physical label is not required when the label elements are shown clearly on the packaging itself.

According to CLP Article 17, a substance and mixture classified as hazardous must bear a label including the following elements:

  • Name, address and telephone number of the supplier(s);

  • The nominal quantity of the substance or mixture in the package where this is being made available to the general public, unless this quantity is specified elsewhere on the package;

  • Product identifiers;

  • Hazard pictograms, where applicable;

  • The relevant signal word, where applicable;

  • Hazard statements, where applicable;

  • where applicable, the appropriate precautionary statements in accordance with Article 22;

  • where applicable, a section for supplemental information in accordance with Article 25.

  • Unique Formula Identifier (UFI), where applicable.

The CLP Regulation requires the label to be written in the official language or languages of the Member States where the substance or mixture is placed on the market, unless the Member State concerned provides otherwise.

Suppliers may accomplish this either by producing multi-language labels covering the official languages of several of the countries where the substance or mixture is supplied, or by producing separate labels for each country, each with the appropriate language or languages.

You must not forget about additional mandatory labelling for specific product types:

  • detergents labelling according to Regulation 648/2004;

  • biocidal products labelling according to Regulation 528/2012;

  • Content of volatile organic compounds according to the Directive 2004/42/ES;

  • Warning that the product contains special hazardous substances under the Regulation REACH 1907/2006;

  • Warning for liquid waxes whose ingestion is harmful to health under the Regulation REACH 1907/2006;

  • Aerosol dispensers: Symbol “3” certifying conformity with the requirements of the Directive 75/324/EEC;

  • Plant protection products labelling according to Regulation 1107/2009.
