The EU POPs Regulation, formally Regulation (EU) 2019/1021, bans or tightly restricts persistent organic pollutants across their entire lifecycle: manufacture, import, sale, use, stockpiling, and disposal as waste. It applies uniformly in every member state and covers substances on their own, in mixtures, and inside finished articles. Compliance sits with whoever puts a product on the EU market, and the rules reach further than the chemicals themselves — waste containing POPs above set concentration limits must be destroyed rather than recycled.1EUR-Lex. Regulation (EU) 2019/1021 on Persistent Organic Pollutants (Recast)
What the Regulation Covers
The regulation implements two international agreements in EU law: the Stockholm Convention on Persistent Organic Pollutants and the POPs Protocol under the 1979 Convention on Long-Range Transboundary Air Pollution. Controlled substances sit in one of four annexes, and the annex determines your obligations.
- Annex I lists prohibited substances. Manufacturing, placing on the market, and using them is banned, whether on their own, in mixtures, or in articles. The list includes DDT, various PCBs, and several PFAS compounds.2EUR-Lex. Regulation (EU) 2019/1021 on Persistent Organic Pollutants (Recast) – Article 3
- Annex II lists restricted substances that may still be produced or used under defined conditions with monitoring requirements.
- Annex III covers substances generated unintentionally as industrial byproducts. Member states must inventory releases and run action plans aimed at eventual elimination.3EUR-Lex. Regulation (EU) 2019/1021 on Persistent Organic Pollutants (Recast) – Article 6
- Annex IV sets the concentration thresholds that decide how waste containing POPs must be handled.
The annexes are amended as the Stockholm Convention adds substances. Chlorpyrifos, long-chain perfluorocarboxylic acids (LC-PFCAs), and medium-chain chlorinated paraffins were added to the Convention’s elimination list at its 2025 meeting; methoxychlor, dechlorane plus, and UV-328 were added in 2023.4Stockholm Convention. The New POPs Under the Stockholm Convention The EU is expected to incorporate LC-PFCAs into Annex I during 2026.
Who Carries the Legal Duty
For an Annex I substance, the prohibition runs across the full commercial chain: manufacturing inside the EU, importing into the EU customs territory, and supplying or making available to any third party, whether sold or given away. Import a finished article containing a banned POP above permitted trace levels and you carry the same legal responsibility as a manufacturer producing the substance in the EU.2EUR-Lex. Regulation (EU) 2019/1021 on Persistent Organic Pollutants (Recast) – Article 3
Two narrow exemptions exist. Laboratory-scale research is permitted, and unintentional trace contaminants (UTCs) are tolerated up to strict ceilings that recognise unavoidable residues left after manufacturing. For individual polybrominated diphenyl ethers (PBDEs), the UTC limit sits at 10 mg/kg in substances, mixtures, or articles.5GOV.UK. Explanatory Memorandum for European Union Legislation Cross a UTC ceiling and the product is legally treated as containing the prohibited substance. It cannot be sold.
PFAS: The Tightest Deadlines Right Now
Three per- and polyfluoroalkyl substances are firmly listed under the regulation: PFOS, PFOA, and PFHxS. The UTC limits on these have been cut sharply in the most recent amendments.
For PFOS and its salts, the UTC limit dropped from 10 mg/kg to 0.025 mg/kg in substances, mixtures, or articles, with a separate 1 mg/kg ceiling for the combined concentration of PFOS-related compounds. The updated limits took effect on 3 December 2025.6EUR-Lex. Amendment to Annex I – Perfluorooctane Sulfonic Acid (PFOS) The PFOA entry was amended in 2025 to remove expired exemptions and tighten UTC limits.
Firefighting foams are the practical flashpoint. Commission Delegated Regulation (EU) 2025/1399 set 3 December 2025 as the deadline for the PFOA phase-out in firefighting foam, with a transitional UTC limit of 10 mg/kg for foam remaining in systems cleaned using best available techniques. Articles containing PFOA already in use before the exemption expiry date may continue to be used.7EUR-Lex. Commission Delegated Regulation (EU) 2025/1399
A separate REACH amendment will ban all PFAS in firefighting foams at concentrations of 1 mg/L or above from 23 October 2030. Portable extinguishers face an earlier deadline of 23 October 2026, and certain high-risk Seveso Directive facilities received a derogation running to 23 October 2035. LC-PFCAs are expected to join Annex I during 2026 following their 2025 addition to the Stockholm Convention, widening the net to more PFAS compounds.4Stockholm Convention. The New POPs Under the Stockholm Convention
Stockpile Notification at 50 kg
Hold more than 50 kg of a regulated POP substance across all your sites and you must notify the relevant competent authority. The threshold covers the total weight of POP-containing material or products in storage, excluding waste. When a new substance is added, the notification is due within 12 months of the amendment taking effect and must be renewed every 12 months after that.
Storage has to prevent leaks, spills, and unauthorised access, with records of conditions and inspections for container degradation. Once the authorised use period for a restricted substance expires, remaining inventory is immediately reclassified as waste and must follow the disposal rules below. That reclassification matters financially, because POP waste requires specialised treatment at permitted facilities.
Waste Rules and Low POP Content Limits
Annex IV sets “low POP content” thresholds. Waste above the relevant threshold must be treated so the POP content is destroyed or irreversibly transformed. The regulation does not allow recycling or recovery of the POP substance itself; the aim is permanent removal from the supply chain.8EUR-Lex. Regulation (EU) 2019/1021 on Persistent Organic Pollutants (Recast) – Article 7
The thresholds vary widely by substance. Examples from Annex IV:
- Brominated flame retardants (sum of certain PBDEs): 500 mg/kg, moving to 200 mg/kg five years after the amendment enters into force
- Hexabromocyclododecane (HBCD): 500 mg/kg
- Short-chain chlorinated paraffins (SCCPs): 1,500 mg/kg
- PFOA and its salts: 1 mg/kg, with PFOA-related compounds at 40 mg/kg
- Pentachlorophenol: 100 mg/kg
- Dioxins and furans (PCDD/PCDF) plus dioxin-like PCBs: 5 µg/kg, using toxic equivalency factors
A lower threshold makes the substance harder to manage. PFOA waste, at 1 mg/kg, requires very sensitive analytical testing and costly high-temperature destruction. Facilities handling POP waste must hold specific environmental permits, and disposal generally involves high-temperature incineration or approved physico-chemical treatment able to break down the chemical bonds in these highly stable compounds. Failure to comply can trigger remediation orders and liability that includes the full cost of cleaning contaminated sites.
How This Sits Alongside REACH
REACH also restricts hazardous chemicals, and some substances appear in both frameworks. The POPs Regulation takes priority: when a substance is listed under the Stockholm Convention and added to the POPs Regulation, any existing REACH restriction in Annex XVII is removed and the POPs entry becomes the controlling instrument.10Environmental Protection Agency. POPs, REACH and RoHS Differences REACH also does not cover waste. Once a product becomes waste, REACH drops away and the POPs Regulation is what governs end-of-life obligations for listed substances.
Penalties and Market Consequences
Article 14 requires each member state to set its own penalties, which must be “effective, proportionate and dissuasive.”11EUR-Lex. Regulation (EU) 2019/1021 on Persistent Organic Pollutants (Recast) – Article 14 Specific fines and criminal sanctions vary by country. National environmental agencies and customs authorities handle enforcement, coordinated across borders through ECHA’s Enforcement Forum.
The financial risk is not limited to fines. Products found to contain prohibited POPs above UTC limits can be removed from the single market entirely. For importers, a non-compliant shipment stopped at customs represents both the loss of the goods and potential liability for disposal costs. Where contaminated waste is involved, site remediation costs can outweigh the original regulatory fine.
