Japan has designated substances such as chlorpyrifos, medium chain chlorinated paraffins, and long-chain PFCA as "Class I Specific Chemicals" and included them in the banned list.
On October 3, 2025, the Japanese Ministry of Health, Labour and Welfare, Ministry of Economy, Trade and Industry, and Ministry of Environment jointly issued a notice soliciting opinions on the draft control measures for substances related to chlorpyrifos, medium chain chlorinated paraffins, long-chain perfluorocarboxylic acids (long-chain PFCA) and their salts, and long-chain PFCA under the Chemical Substance Review and Manufacturing Management Law (Chemical Review Law). The public can submit feedback through the electronic government comprehensive window (e-Gov) in accordance with the official website form format before November 2, 2025.

01. Add controlled substances
The draft plan designates chlorpyrifos, medium chain chlorinated paraffins, long-chain PFCA and its salts, and related substances as "Class I Specific Chemicals". Starting from 2026, the manufacturing and import activities of these chemicals must be licensed. (In principle, its manufacturing and import are prohibited)
- Thiophosphate O, O-diethyl-O - (3,5,6-trichloro-2-pyridyl) (Chlorpyrifos)
- Medium chain chlorinated paraffins (1) substances or mixtures containing straight chain chlorinated alkanes with 14 to 17 carbon atoms and a chlorine content of 45% or more by weight; Or (2) substances or mixtures containing straight chain chlorinated alkanes with 14 to 17 carbon atoms of the following molecular formulas: C ₁₄ H ₍③₀₋ᵧ₎ Cl ᵧ (y ≥ 5), C ₁₅ H ₍③₂₋ᵧ₎ Cl ᵧ (y ≥ 5), C ₁₆ H ₍③₄ ₋ᵧ₎ Cl ᵧ (y ≥ 6), C ₁₇ H ₍∝₆₋ᵧ₎ Cl ᵧ (y ≥ 6); Or substances that satisfy (1) and (2))
- Long chain perfluorocarboxylic acids (long-chain PFCA) (with 9 to 21 carbon atoms) and their salts
- Long chain PFCA related substances (referring to compounds containing perfluoroalkyl groups (with 8 to 20 carbon atoms) directly bound to atoms other than fluorine, chlorine, or bromine, which can undergo chemical changes through natural action to generate PFCA (limited to those with 9 to 21 carbon atoms) (specifically regulated by relevant provincial regulations)

02. It is prohibited to import products containing the above substances
The draft plan designates chlorpyrifos, medium chain chlorinated paraffins, long-chain PFCA and its salts, and related substances as "Class I Specific Chemicals". Starting from 2026, the manufacturing and import activities of these chemicals must be licensed. (In principle, its manufacturing and import are prohibited)

03. Other requirements
This control is very strict. Except for approved essential uses, the use of these substances will be completely prohibited. At present, the draft does not provide any exemptions for any use, which means that once passed, it will immediately achieve a comprehensive ban.
For fire extinguishers, extinguishing agents and foam extinguishing agents containing long-chain PFCA and its salts and related substances, the draft requires that special technical standards formulated separately must be followed when handling to ensure safe and harmless treatment.
It is recommended that relevant companies take immediate action to review their supply chains, identify restricted substances, and seek compliant alternatives to ensure that their products meet relevant requirements.
