Singapore: New Licensing Requirements for Hazardous Substances

Singapore has added two amendments to its chemicals law: Environmental Protection and Management Act 1999 (Amendment of Second Schedule) Order 2023 and Environmental Protection and Management (Hazardous Substances) (Amendment) Regulations 2023. As of August 21, 2023, the amendments require manufacturers and importers to have a license to manufacture and/or import certain chemicals. The new regulations apply to 26 substances, including:

  • Diethyl phosphite, which is needed to manufacture flame retardants and agricultural chemicals among other uses
  • Perfluoroisobutylene (PFIB), which is used to manufacture semiconductors
  • Thiodiglycol, which is used in many products, including dyes, paper, varnishes, paints, and ink
  • Thionyl chloride which is used in the manufacture of dyes, biocides, plastics, and batteries
  • Triethanolamine, which is used in various sectors as a lubricant

Companies that wish to continue to use these substances must prove that they can handle and store them safely. A special labeling requirement is also linked to the sale of the substance.
