The GHS at the United Nations

Canada and other international partners, including the United States and the European Union, have worked together to develop a single, globally harmonized system to address classification of chemicals according to their hazards and communicate the related information through labels and safety data sheets.

Additional information on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) activities at the United Nations level, including up-to-date information on the GHS classification criteria, and requirements for labels and safety data sheets as well as other criteria, is available on the  United Nations Economic Commission for Europe (UNECE) website.

The GHS is a dynamic system. The United Nations Sub-Committee of Experts on the GHS (UNSCEGHS) meets twice a year to work on developing potential new hazard classes as well as resolving specific issues, and updating the latest GHS publication.

The UNSCEGHS:

  • makes the GHS available for worldwide use and application;
  • makes guidance available on the application of the GHS; and,
  • promotes understanding and use of the system and encourages feedback.
