Central Administrative Court Upholds Ban on Paraquat and Chlorpyrifos
The Central Administrative Court has ruled that the classification of paraquat and chlorpyrifos as Type 4 hazardous substances is legally valid.
On August 3, 2026, Prachachat Business reported that the Central Administrative Court in Thailand issued a ruling confirming the legality of the government's decision to classify paraquat and chlorpyrifos as Type 4 hazardous substances. This classification effectively bans the use, possession, and distribution of these chemicals within the country.
The Ministry of Industry has acknowledged the court's decision, stating that the ruling serves as a significant precedent for prioritizing public health and the broader public interest. The Ministry indicated that it will continue to enforce strict oversight regarding the management of hazardous substances to ensure compliance with this legal standard.
For residents and travelers, this development reinforces the Thai government's ongoing commitment to regulating agricultural chemicals that have been linked to health concerns. While the legal status of these substances is now confirmed by the court, the practical implications for agricultural supply chains and the availability of specific produce may continue to evolve. It remains to be confirmed how the Ministry of Industry will adjust its long-term monitoring protocols or if further regulatory actions regarding other agricultural chemicals will follow in the wake of this judicial precedent. Individuals should remain aware that the use of these specific substances is prohibited under current Thai law.
