Chemical Regulatory Services in Thailand


Cleaning and disinfectant products are called, identified, and regulated differently across various countries and regions, making it very challenging for the industry to place these products in different markets.

In Thailand, these products are regulated by Food and Drug Administration Thailand (FDA Thailand) under the ambit of the Hazardous Substance Act. Further, as per the act, these products, depending on the chemical and use, can fall under the below-mentioned types:

Type 1

Type 2

Type 3

Type 4

  • Very less impact on human and environmental health
  • Does not require registration but reporting to a competent authority about the product facts/ information

For example – some cleaning products, and Hypochlorite-based pool disinfectants

  • Some degree of risk to human and environmental health
  • Requires registration

For example –Disinfectants not falling under Type 1 and carrying a higher degree of risk than Type 1

  • A higher degree of risk than Type 2 classified products
  • Requires registration and import license

For example – Acid/ aldehyde/alkaline-based cleaners and disinfectants

  • Carries very high risk due to their severe hazardous intrinsic properties like mutagens, carcinogens, etc.
  • Any kind of use is prohibited


For example - DDT, Dieldrin, etc.


For all the manufacturers of products classified under hazardous substances, the GMP requirement is mandatory as per the act.
