The information on hazardous substances to be reported to Thailand’s Food and Drug Administration (FDA) must now include classification data, based on the 3rd revised edition of the UN Globally Harmonized System (GHS) Regulations.


The control of manufacture, import, export and possession of hazardous substances in Thailand is mainly regulated through the Hazardous Substance Act B.E. 2535.

Hazardous substances in list No. 4 must be notified to the FDA, under the Act. These include:

  • household and cleaning products
  • water and drill chemical treatment
  • public health pesticides
  • disinfectants
  • alkyl cyanoacrylate adhesives

FDA has implemented GHS on hazardous substances/products for household and public health use, through the Notification of Ministry of Public Health on Classification System and Hazard Communication of Hazardous Substances under FDA control 2015 (Link (Thai)). The Notification has been effective since 20 March 2015, with transition periods of 1 and 5 years for substances and mixtures, respectively.

Recently, FDA urged the manufacturers and importers of the mixture to comply with the requirements annexed to the Notification by 19 March 2020 (Link (Thai)):

  • Evaluate product against the GHS hazard classification criteria for 16 classes of physical hazards, 10 classes of health hazards, and 2 classes of environmental hazards
  • Apply correct labeling
  • Prepare safety data sheets

Non-compliance shall be liable to the penalty clauses as provided by law.
