Taiwan’s Ministry of Environment has announced stricter controls on several high- risk chemicals, including PFOS, PFOA, nonylphenol (NP), nonylphenol ethoxylates (NPEO), and cycloterpenes. Starting June 1, 2025, these substances will be listed as toxic or of concern，with new concentration limits and use restrictions. 

PFAS Under Tighter Control 

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are, part of the broader group of per- and polyfluoroalkyl substances (PFAS) , They are known for their persistence in the environment and their ability to accumulate in living organisms., This poses risks to ecosystems and human health. Following international conventions likeIn line with the Stockholm Convention, Taiwan is now regulating over 350 related PFAS compounds. 

Stricter Limits on NP and NPEO 

NP and NPEO, which are classified as endocrine disruptors, have been banned in household cleaning products in Taiwan since 2007. Now, stricter rules will cap their use at 0.1% in cleaning products and high-risk applications, and ban the import of such products. 

Cycloterpenes Ban in Specific Applications 

Due to their toxicity and risk of bioaccumulation, cycloterpenes,  will be banned in antifouling paints, systems, and biocides.

Grace Period and Industry Guidance 

To help businesses transition, the ministry will offer a grace period of one and a half to two years. Officials also encourage industries to find safer alternatives to protect health and the environment.
