On June 28, 2023, Thailand’s Food and Drug Administration (FDA) notified WTO of the proposed updates of the notification requirements for Type 1 hazardous substances (only for items under the FDA’s responsibility) for comments. Thailand’s current regulation regarding this issue is the Notification of the Ministry of Public Health Re: Notification of Fact Relating to Type 1 Hazardous Substances Under the Responsibility of the FDA B.E. 2562 (2019). Once the proposed updates are adopted and come into force, the 2019 version will be repealed. New regulation is expected to take effect after 180 days from the date of its publication in the Government Gazette. Comments are welcome before September 8, 2023.
