The transition to the Globally Harmonized System of Classification and Labelling of Chemicals Revision 7 (GHS 7) ends on 31 December 2022. 

From 1 January 2023, GHS 7 must be used to classify chemicals and prepare labels and safety data sheets (SDS) for newly manufactured and imported hazardous chemicals in Australia (unless otherwise advised by your work health and safety regulator). The SDS for existing chemicals should also comply with GHS 7 from 1 January 2023. Note that Western Australia’s GHS 7 start date is 31 March 2023.
