Key takeaway
What This Development Means
Japan is revising its Chemical Substances Control Law to update the exemption list. Newly added substances include polymers and derivatives deemed safe, while environmentally persistent chemicals like perfluorinated acrylates are removed. Public comments are open until 3 February 2025, with the changes taking effect in March.
What are the newly added substances to Japan's chemical exemption list, and why were they selected?
The proposed amendments to Japan's Chemical Substances Control Law aim to add several compounds to the exemption list. Newly included substances, such as ethane-1,2-diol-based polymers, 2-ethylhexyl acrylate polymers, and cyclohexyl methacrylate derivatives, are widely used in industrial applications like coatings, adhesives, and specialty resins. These substances have been selected for exemption because recent scientific studies indicate they are not persistent, bioaccumulative, or toxic to human health or the environment. These updates reflect Japan's commitment to evidence-based regulation while reducing unnecessary reporting burdens for safe chemicals.
Why are certain substances, such as perfluorinated acrylates, being removed from the exemption list?
Substances like perfluorinated acrylates and 3-chloro-2-hydroxypropyl methacrylate copolymers are proposed for removal from the exemption list under the Chemical Substances Control Law. New research has revealed that these compounds exhibit concerning properties, such as environmental persistence and bioaccumulation. For example, perfluorinated acrylates have been linked to long-term ecological harm and potential health risks. Their removal ensures that chemicals with potentially harmful effects are subjected to stricter monitoring and evaluation, aligning with global efforts to phase out hazardous substances.

The Japanese government is amending its Chemical Substances Control Law (CSCL) to update the list of substances exempt from notification requirements. The proposed changes will take effect in March 2025, with public comments open until 3 February 2025.
Key Amendments To The Chemical Substances Control Law
The CSCL requires manufacturers and importers of general chemical substances to annually report production and import volumes. However, some substances, deemed to pose minimal risk, are exempt from this requirement. The Ministry of Health, Labour and Welfare, the Ministry of Economy, Trade and Industry, and the Ministry of the Environment have proposed amendments to the exemption list, aiming to include new substances and remove others based on updated scientific evidence.
Key updates include:
Newly Added Substances (Annex 1):Ethane-1,2-diol-based polymer compounds – Widely used in coatings, these substances lack bioaccumulative properties.2-Ethylhexyl acrylate polymers – Common in adhesives, these compounds do not exhibit long-term toxicity to humans or ecosystems.Cyclohexyl methacrylate derivatives – Known for their application in specialty resins, they are now deemed safe under the latest guidelines.Substances Proposed for Removal (Annex 2):3-Chloro-2-hydroxypropyl methacrylate copolymers – These are flagged due to new evidence of environmental persistence.Certain perfluorinated acrylates – Previously listed as exempt, they are now linked to bioaccumulation concerns and potential health risks.
Why The Amendments Are Necessary
The inclusion and removal of these substances reflect Japan’s commitment to environmental protection and public safety. Newly added compounds are supported by data showing no significant ecological or human health risks. Meanwhile, substances removed from the exemption list are flagged for re-evaluation due to concerns such as toxicity, persistence, or bioaccumulation.
Timeline For Public Input
The draft was published on 4 January 2025, and public comments will be accepted until 3 February 2025. Stakeholders are encouraged to submit feedback via the e-Gov platform, email, or postal mail.
