Effective from June 1st, 2025! Taiwan strengthens control over toxic substances such as PFAS and cyclobutane
Time：
2025-06-10
New PFOS, PFOA, NP, NPEO and cyclobutane in Taiwan, China are toxic or concerned chemicals, and strict control measures have been formulated, which will come into effect on June 1, 2025!
In May 2025, the Chemical Substance Administration of the Ministry of Environment of Taiwan, China, China announced the revision of the List of Toxic Chemicals and Their Operation and Management Matters and the List of Concerned Chemicals and Their Operation and Management Matters, adding perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), nonylphenol (NP), nonylphenol ethoxyalcohol (NPEO), cyclobutane and other substances as toxic or concerned chemicals, and formulated strict control measures. The new regulations will come into effect on June 1, 2025, aiming to reduce the risks of chemicals to the environment and human health.
The relevant departments in Taiwan have pointed out that PFOS and PFOA are perfluorinated and polyfluoroalkyl substances, which are not easily decomposed in the environment and have bioaccumulation. They may affect ecosystems and human health through the food chain. The United Nations Stockholm Convention has also included PFOS and its salts and related compounds, PFOS and its salts and related compounds in Annex A should be eliminated and Annex B should be restricted. Add 5 PFOS salts and related compounds, 352 PFOA salts and related compounds to the reference convention, and limit their use in accordance with the convention.
1、 Add a total of 397 toxic chemicals to the list (effective from June 1, 2025)
Including PFOS, its salts, and related compounds (5 types)
Including PFOA, its salts, and related compounds (352 types)
12 types of nonylphenol (NP)
28 types of nonylphenol polyethylene glycol (NPEO)
357 types of PFAS (perfluorinated and polyfluoroalkyl substances):
40 types of nonylphenol related substances:
2、 Implement buffer period arrangement
PFOS/PFOA related compounds: Provide a 1.5-year buffer period to allow companies sufficient time to complete compliance preparations such as licensing, registration, or application adjustments
Nonylphenol and NPEO: Buffer periods range from 1.5 to 2 years, classified based on specific concentrations and CAS numbers:
Concentration ≥ 5%: 1.5 years
Concentration ≥ 0.1% but<5%: 2-year buffer
3、 Main prohibited and permitted uses
Total ban: Nonylphenol and NPEO are prohibited from the following uses (except for controlled recycling/incineration, and are not used or sold locally)
Manufacturing industry and public institution cleaning agents
Textile or leather finishing
metalworking
Pulp or paper making
Permitted uses (can still be used through compliance processes, including):
Research, experimentation, and educational purposes
pharmacy
Synthetic resin and phenolic resin raw materials
Antioxidants and stabilizers
Spermicide
Coatings, inks, dispersants, adhesives, etc
IV. Revision of Control Concentration
The newly established control concentration limit for nonylphenol/NPEO is 0.1% w/w, which complies with the EU REACH practice
The controlled concentrations of PFOS and PFOA are full concentration management (i.e. no allowable content)
5、 Corporate Obligations and Suggestions
Submission of Hazard Prevention and Response Plan
Transportation and labeling comply with new regulations
Container and facility labeling safety data sheet (SDS)
Professional technical and emergency personnel allocation
Change licenses, registration and approval documents, etc
The following actions need to be completed to determine the usage period of each item in the revised civilization:
Suggest relevant enterprises to start as soon as possible:
Review and update the license/registration status of major operational substances
Develop or revise internal compliance plans
Arrange alternative supply or waste disposal plans during the buffer period
Pay attention to the follow-up operation guidelines or technical specifications of the Environmental Protection Agency
6、 Key Regulatory Update for Taiwan in 2025
|
Project |
Regulatory content |
| Management type | Toxic chemical substances (Class I) |
| Scope of management | PFOS/PFOA ontology+its salts+related compounds, totaling approximately 357 items |
| Control concentration | No exemption threshold, meaning that any concentration is subject to regulation |
| Prohibited use | Manufacturing, input, output and operation (such as detergent, antifouling agent, foam extinguishing agent, etc.) |
| Buffer period | 1.5 years from the date of announcement (expected until the end of 2026), during which companies are allowed to apply for approval and other procedures |
7、 Suggestions for enterprise response
Check whether the raw materials contain PFOS/PFOA or its derivatives (can be compared by CAS number)
Contact the supplier to confirm ingredient updates and whether alternative substances have been used
Apply for legal operation/alternative approval, and if necessary, provide a description of the intended use and a timeline for alternative solutions
Establish management procedures to ensure that transportation, storage, and disposal comply with the requirements of the new regulations
Cooperate with the Taiwan Environmental Protection Agency for inspection or declaration of operations
