GHS Rev. 10 | New Amendments to Globally Harmonized System, including Non-Animal Test Methods and Classification of Metals for Aquatic Hazard

The Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labelling of Chemicals has announced significant updates to the ninth revised edition of the GHS, marking its tenth revised edition (GHS Rev. 10, 2023). These amendments, adopted during the eleventh session of the committee on December 9, 2022, address several crucial areas, with a particular emphasis on enhancing the classification and labeling of chemicals.

One of the highlights of these amendments is the refinement of the classification procedure for desensitized explosives, outlined in chapter 2.17 of the GHS. This adjustment aims to bolster safety measures and ensure the proper handling and transportation of such hazardous materials.

In a move towards ethical practices, the GHS Rev. 10 incorporates non-animal testing methods for health hazard classification. Specifically, the updated chapters (3.2, 3.3, and 3.4) now include alternatives to animal testing for assessing skin corrosion/irritation, serious eye damage/irritation, and respiratory or skin sensitization. This shift reflects the growing global sentiment towards cruelty-free testing methodologies.

A significant aspect of these amendments involves the rationalization of precautionary statements. This strategic streamlining seeks to enhance comprehensibility for end-users while still maintaining effectiveness for labelling practitioners, thus contributing to safer handling practices of chemicals.

Another change lies in the revision of annexes 9 and 10 of the GHS, providing new guidance on classifying metals and metal compounds for long-term aquatic hazard.

The electronic version of GHS Rev. 10 is available for free consultation in the six official languages of the United Nations, including Arabic, Chinese, English, French, Russian, and Spanish.
