Malaysia’s Department of Occupational Safety and Health (DOSH) is calling on companies to submit detailed information on hazardous chemicals by 31 March 2026. The requirement applies to all manufacturers and importers handling one metric tonne or more of hazardous chemicals per year.
The initiative aims to strengthen chemical traceability, improve hazard communication, and enhance workplace safety across the country.
What companies must submit
Under the CLASS Regulations 2013, DOSH instructs companies to provide data through its online Chemical Information Management System (CIMS), including:
- product name
- chemical name and CAS number
- mixture composition
- hazard classification
- annual quantity manufactured or imported
To ensure accurate hazard classification, DOSH directs companies to consult the Industry Code of Practice on Chemicals Classification and Hazard Communication (ICOP CHC) — specifically Part 1 of the 2019 edition and Parts 2–4 of the 2014 edition.
Companies may apply a higher hazard category when appropriate, but any move to use a lower classification must be backed by supporting evidence.
Why the new requirement matters
The reporting obligation supports Malaysia’s efforts to maintain consistent labelling, improve the quality of Safety Data Sheets (SDSs), and support safer workplaces and downstream chemical use. It also helps keep the country aligned with international chemical safety standards.
