EU POPS REGULATORY UPDATE
On June 30, 2026, the European Commission adopted a delegated regulation amending Regulation (EU) 2019/1021 as regards chlorpyrifos. The amendment is expected to be published in the Official Journal of the European Union and will enter into force on the twentieth day following its publication. Companies placing substances, mixtures or articles on the EU market should monitor the final text and review potential POPs-related compliance risks. For broader regulatory support, see REACH24H's EU POPs Regulation compliance support.

What Will Change?
According to the adopted delegated regulation, chlorpyrifos will be added to Annex I of Regulation (EU) 2019/1021. The substance information is as follows:
| Substance | CAS No. | EC No. |
|---|---|---|
| Chlorpyrifos | 2921-88-2 | 220-864-4 |
In the EU, chlorpyrifos is not approved as an active substance in plant protection products or biocidal products. Therefore, the European Commission states that chlorpyrifos should be listed in Annex I to Regulation (EU) 2019/1021 without specific exemptions.
The amendment also introduces a limit value for chlorpyrifos when it occurs as an unintentional trace contaminant in substances, mixtures and articles. Based on the draft information available, the concentration limit is expected to be less than or equal to 0.01 mg/kg (0,000001 % by weight).
Companies should continue to monitor the final text published in the Official Journal to confirm the final entry-into-force date and the wording of the Annex I entry. The adopted delegated regulation is available through the Council of the European Union document register.
Why Chlorpyrifos Is Being Controlled as a POP?
Chlorpyrifos is an organophosphorus insecticide that has historically been used for pest control in agricultural applications. Due to concerns over its toxicity, environmental persistence and potential risks to human health and ecosystems, it has been increasingly restricted or banned in multiple jurisdictions.
Under the Stockholm Convention framework, substances listed in Annex A are subject to elimination measures. The EU POPs Regulation implements the EU's obligations under the Stockholm Convention by prohibiting, phasing out or restricting listed POPs in the EU market.
What Companies Should Do Next?
Although chlorpyrifos is primarily known as a pesticide active substance, the EU POPs Regulation can affect a broader range of supply chains because it applies to substances, mixtures and articles placed on the EU market.
Companies exporting to or operating in the EU should consider the following actions:
Check whether chlorpyrifos may be present in products or raw materials: Review substances, mixtures, articles, intermediates, additives, recycled materials and legacy supply chains where unintended contamination may be possible.
Update restricted substance lists and supplier requirements: Add chlorpyrifos to internal POPs monitoring lists and request updated supplier declarations where relevant.
Assess testing needs based on product risk: Testing may be necessary for products, raw materials or supply chains with possible historical use, contamination or uncertain composition.
Monitor the Official Journal publication: The regulation will apply after the twentieth day following its publication in the Official Journal. Businesses should confirm the final legal text and implementation date once published.
Track other POPs developments separately: The EU is also progressing POPs control discussions for long-chain perfluorocarboxylic acids (C9-C21 PFCAs), their salts and related substances, and medium-chain chlorinated paraffins (MCCPs). These substances are subject to separate regulatory developments and should be monitored independently. See REACH24H's earlier update on PFCAs, MCCPs and chlorpyrifos under the EU POPs Regulation.
How REACH24H Can Help
This chlorpyrifos amendment shows that the EU is continuing to align its POPs Regulation with international decisions under the Stockholm Convention. For companies placing chemicals, mixtures or articles on the EU market, POPs compliance is not limited to intentionally added substances. Unintentional trace contaminants, legacy substances and recycled material streams may also create compliance risks.
REACH24H recommends that companies establish a routine POPs monitoring mechanism, review product composition data, strengthen supplier communication and prepare evidence of compliance where necessary.
Regulatory tracking: Monitor EU POPs Regulation updates and related Annex I changes.
Substance list monitoring: Screen products, raw materials and supplier data against POPs requirements.
Product compliance assessment: Review potential risks for substances, mixtures and articles placed on the EU market.
Supply chain risk review: Support supplier communication, documentation review and risk-based compliance planning.
For companies managing POPs risks across substances, mixtures and articles, REACH24H provides EU POPs Regulation compliance support, including regulatory tracking, substance list monitoring, product compliance assessment and supply chain risk review.
