Chemical Registration in Thailand

Chemical Registration in Thailand – Overview

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

Table 1: Classification of Chemical Products Under the Hazardous Substances Act

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 product 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 the Hazardous Substances Act, the GMP requirement is mandatory as per the act.
