Key takeaway
What This Development Means
Dechlorane Plus is now restricted in the EU under the POPs Regulation, with significant implications for regulated sectors. Professionals must act swiftly to meet new trace contaminant limits, manage exemptions, and prepare for enforcement. Final details await publication in the EU’s Official Journal.
What is the Dechlorane Plus restriction under the EU POPs Regulation?
Dechlorane Plus is now listed under Annex I of Regulation (EU) 2019/1021. The substance is subject to strict use restrictions, with trace contaminant limits of 1000 mg/kg initially and 1 mg/kg after 30 months. Some sector-specific exemptions are granted for five years.
How does this affect spare parts in aerospace and automotive sectors?
Spare parts containing Dechlorane Plus used in aerospace, automotive, medical, and industrial sectors can be placed on the market until 2043 or the end of service life. However, businesses must document compliance and monitor future regulatory reviews planned for 2028.
The European Commission has adopted new restrictions on Dechlorane Plus, a widely used flame retardant, by amending Regulation (EU) 2019/1021 on persistent organic pollutants (POPs). This change, announced on 15 May 2025, introduces phased bans and exemptions that directly affect professionals across the chemicals, automotive, aerospace, medical, and electronics sectors.
What Is Dechlorane Plus And Why Is It Regulated?
Dechlorane Plus is a chlorinated flame retardant used in adhesives, tapes, wire harnesses, lubricants, and polymer matrices. Its persistence, bioaccumulation potential, and suspected toxicity led to global regulatory scrutiny. The substance was listed in Annex A of the Stockholm Convention in 2023, triggering the EU's obligation to align its domestic rules under the POPs Regulation.
The European Chemicals Agency (ECHA) and the European Commission have recognised that while certain critical applications exist, the overall goal is to eliminate the use of Dechlorane Plus to protect human health and the environment.
Key Compliance Deadlines And Exemptions
The new EU regulation establishes two thresholds for Dechlorane Plus in products:
- Until 30 months after entry into force: 1000 mg/kg (0.1%) is permitted as an unintentional trace contaminant (UTC).
- After 30 months: The limit tightens to 1 mg/kg (0.0001%).
Exemptions apply for up to five years, including:
- Aerospace, space and defence
- Medical imaging and radiotherapy devices
- Automotive and industrial spare parts
- Diagnostic and analytical instruments
These exemptions allow continued use and servicing of existing equipment and may be reviewed for extension by April 2028.
Industry-Wide Implications And Next Steps
Stakeholders across the supply chain must assess product formulations, procurement practices, and legacy equipment inventories. The restriction particularly affects OEMs, spare parts suppliers, and end-users in regulated sectors. Risk assessments and substitution planning should begin immediately.
The Commission has indicated that the volume of Dechlorane Plus used in exempted spare parts is minimal, but manufacturers must document usage and ensure traceability to comply with future enforcement.
