The European Union is amending its Persistent Organic Pollutants (POPs) Regulation, specifically targeting Dechlorane Plus, a highly chlorinated flame retardant, by adding it to Part A of Annex I of Regulation (EU) 2019/1021.
The amendment, namely Commission Delegated Regulation (EU) 2025/1930, adopted on May 15, 2025 and published on September 25, 2025, introduces stringent controls on the production, placing on the market, and use of Dechlorane Plus within the EU. It shall enter into force on October 15, 2025.
As per the Annex, the following entry is added to Part A of Annex I of Regulation (EU) 2019/1021:
| Substance | CAS No. | EC No. |
| Dechlorane Plus, including its syn-isomer and anti-isomer | 13560-89-9 135821-03-3 135821-74-8 | 236-948-9 |
Concentration Limits and Phased Implementation
As per Article 3 of Regulation (EU) 2019/1021, the manufacturing, placing on the market and use of Dechlorane Plus, whether on their own, in mixutres or in articles shall be prohibited.
The regulation establishes unintentional trace contaminant (UTC) for Dechlorane Plus in substances, mixtures, or articles, with a phased approach to allow for industry adjustment:
•Until 15 April 2028: A transitional period allows for concentrations of Dechlorane Plus up to 1,000 mg/kg (0.1% by weight).
•After 15 April 2028: allows for concentrations of Dechlorane Plus up to 1 mg/kg (0.0001% by weight).
Derogations
The regulation includes specific derogations for the placing on the market and use of Dechlorane Plus. These exemptions are time-limited and apply to specific uses:
Until 26 February 2030, derogations are granted for:
Aerospace, space, and defense applications
Medical imaging applications
Radiotherapy devices and installations
For spare parts and repair of the following, longer derogations are in place, applying until the end of the service life of the article or until 31 December 2043 (whichever comes earlier), provided Dechlorane Plus was initially used in their production:
Land-based motor vehicles
Stationary industrial machines used in agriculture, forestry, and construction
Marine, garden, forestry, and outdoor power equipment (excluding those mentioned above)
Aerospace, space, and defense applications
Instruments for analysis, measurements, control, monitoring, testing, production, and inspection
Furthermore, for medical devices and in vitro diagnostic medical devices, derogations for spare parts and repair of the following extend until the end of their service life, again contingent on Dechlorane Plus being initially used in their production:
Medical devices and accessories within the scope of Regulation (EU) 2017/745
In vitro diagnostic medical devices and accessories within the scope of Regulation (EU) 2017/746
