Latest notice (G/TBT/N/THA/798/Add.1, 24 June 2026)
Draft Notification of the Ministry of Public Health RE: Classification of Schedule IV Narcotic Drugs (No. 4) B.E. ….
This draft notification aims to amend the exemption criteria for phenylacetic acid, classified as a Schedule IV narcotic drug under the Narcotics Code. The current exemption is limited to food and animal feed flavorings at a concentration not exceeding 5%. The proposed amendment expands the exemption to include its use in cosmetics and household or public health hazardous substances as a fragrance ingredient at a concentration not exceeding 10%, and in finished products used solely for fragrance purposes at a concentration not exceeding 5%, in order to support industrial benefits and positively impact the country's economy. Nevertheless, this must remain under regulatory control in accordance with the relevant legislation to prevent any risk of misuse and diversion from the legitimate system.
Piperonal was originally classified as a Schedule IV narcotic drugs under the Narcotics Code, without any specified exemptions. However, in order to facilitate its use for industrial purposes while ensuring appropriate and comprehensive regulatory oversight to prevent diversion for illicit use ― an amendment has been made to introduce specific exemption conditions. Under this amendment, piperonal shall not be classified as a Schedule IV narcotic drugs when used as a component in flavouring agents for food products, cosmetics, or hazardous substances intended for household or public health use, provided that the concentration of piperonal does not exceed 10%. In addition, Piperonal used as a component in food products, cosmetics, or hazardous substances intended for household or public health use, at a concentration not exceeding 1%, shall be exempted from classification as a Schedule IV narcotic drugs.
