The GHS 10th revised edition contains a number of amendments, some newly added content and guidance relating to the classification and labelling of chemical substances and mixtures.

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an international framework developed to standardise and communicate the hazards associated with chemicals. It was created by the United Nations to improve the safety of handling, transporting, and using chemicals worldwide. The main purpose of the GHS is to ensure that information about the potential hazards of chemicals is consistently conveyed to workers, consumers, emergency responders, and other stakeholders, regardless of their location or the language they speak. This is the GHS 10th Revised Edition.
