On 1 July 2025, the transition period for the introduction of the tenth revised edition of the Globally Harmonized System for Classification and Labelling of Chemicals (GHS 10) was completed.  The South African Department of Employment and Labour previously released Draft Regulation No. 50431, which introduces revised guidelines for limiting exposure to hazardous chemical agents (HCAs).  A key element of the draft is the adoption of GHS 10, which is scheduled to take effect from 1 July 2025.  Comments from stakeholders were due on 5 July 2024. 

Key Updates include: 

• Adoption of GHS 10 by 1 July 2025, with phase-in schedules for future revisions: 

• GHS 11: by July 2027 

• GHS 12: by July 2029 

• Stricter labelling rules, including pictogram sizes and clearer disclosure of ingredients, especially for carcinogens and Specific Target Organ Toxicity STOT hazards.
