Globally Harmonized System of Classification and Labelling of Chemicals (GHS Rev. 10, 2023)

Copyright © United Nations, 2023 - All rights reserved

At its eleventh session (9 December 2022), the "Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labelling of Chemicals" adopted a set of amendments to the ninth revised edition of the GHS addressing, among other topics :

  • the classification procedure for desensitized explosives (chapter 2.17); 

  • the use of non-animal testing methods for classification of health hazards, in particular: skin corrosion/irritation (chapter 3.2), serious eye damage/irritation (chapter 3.3) and respiratory or skin sensitization (chapter 3.4);

  • further rationalization of precautionary statements to improve users’ comprehensibility while taking into account usability for labelling practitioners; and

  • the review of annexes 9 and 10 to ensure alignment of the classification strategy, guidance and tools on metals and metal compounds with the provisions for long-term aquatic classification toxicity in chapter 4.1.

The tenth revised edition of the GHS takes account of these amendments which were circulated as document ST/SG/AC.10/50/Add.3.
