Unlike RoHS, which targets EEE specifically, POP Regulation applies across all product categories and in many cases at stricter concentration limits, making it a mandatory layer of BoM screening for any hardware sold in the EU.

It prohibits the manufacture, use, placing on the market, and export of listed POPs. For electronics, the most relevant substances are perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and its salts and related compounds, polybrominated biphenyls (PBBs), and certain polybrominated diphenyl ethers (PBDEs) including DecaBDE. Concentration limits apply even in articles. ### Flame retardants in electronics — the key risk area Flame retardants are the primary POP risk in electronics. Many halogenated flame retardants historically used in PCBs, cables, housings, and foams are listed or being listed as POPs. DecaBDE, which was widely used in electronics housings, is listed with a specific articles exemption that is narrowing. PFOS, used historically in some circuit board coatings and firefighting foams, is listed with strict concentration limits. Manufacturers sourcing components from regions where legacy flame retardants remain in use must screen incoming parts. ### Interaction with RoHS and REACH POP Regulation, RoHS, and REACH all restrict substances in electronics but through different mechanisms. RoHS restricts specific hazardous substances in electrical and electronic equipment by category. REACH restricts substances through authorisation, restrictions, and SVHC candidate list obligations. POP Regulation bans or severely limits substances as a class, often at lower limits than other frameworks, and it applies to all articles regardless of whether they are EEE or fall under RoHS. The three regimes can and do overlap — a substance restricted under REACH may also be a listed POP. ### Unintentional release and waste obligations For POPs with unintentional release pathways (dioxins, furans, PCBs from industrial processes), the Regulation requires best available technique (BAT) controls. For electronics containing listed POPs, waste management obligations kick in: products containing POPs above threshold concentrations must be managed as hazardous waste. This connects POP Regulation to WEEE Directive obligations — electronics recyclers must identify and safely manage POP-containing components separately from general material streams. ## Compliance process 01 Obtain the current list of substances listed in Annexes I–IV of POP Regulation (EU) 2019/1021 and check for any recent amendments — the list is updated as the Stockholm Convention adds new substances. 02 Screen your bill of materials (BoM) and incoming components against the listed POPs, focusing on flame retardants in PCBs and housings, fluorochemical coatings, and any legacy components from supply chains in regions where older materials may still be in use. 03 Request compliance declarations from suppliers confirming that components do not contain listed POPs above the applicable concentration limits specified in the Annex to the Regulation for each listed substance. 04 Where test data is needed, use certified analytical laboratories to test for PFOS, PFOA, PBDEs (including DecaBDE), and PBBs in materials where declarations alone are insufficient due to supply chain complexity. 05 Coordinate with your product compliance team to check whether any substance is restricted under both POP Regulation and RoHS — and apply the lower of the two applicable limits to avoid dual non-compliance. 06 Update your technical file and substance compliance documentation to include POP Regulation coverage, distinguishing it clearly from your RoHS and REACH SVHC documentation to avoid gaps during market surveillance inspections. 07 For products at end of life, inform your waste logistics partners which product lines contain POP-restricted substances above threshold concentrations so they can apply the correct hazardous waste treatment under the WEEE and waste framework directives. ## Frequently asked questions ### Is DecaBDE still allowed in electronics? DecaBDE (decabromodiphenyl ether) is listed in Annex I of POP Regulation with specific exemptions including a transitional exemption for spare parts for vehicles and certain legacy applications. For new electronics products, the exemption has ended for most applications and DecaBDE must be replaced. Check the current Annex I entry and any specific exemption decision for your product category before assuming the exemption applies. ### How does POP Regulation treat PFOS in electronics? PFOS is listed in Annex I with a limit of 10 μg/m² for treated textiles, and 0.001% by mass in other parts and articles. Electronics applications where PFOS was historically used (certain photoresist coatings, metal plating) are now effectively prohibited at these limits. Products containing PFOS above threshold must not be placed on the EU market, and some permitted use derogations require specific Commission approval. ### Does POP Regulation apply to imported second-hand electronics? Yes — POP Regulation applies to articles placed on the EU market, including imported second-hand or refurbished electronics. Products placed on the market after the applicable restriction date must not contain listed POPs above threshold concentrations regardless of when they were originally manufactured. This creates a specific compliance challenge for refurbishers and traders in used electronics who may not have full visibility into original material specifications. ### What are the penalties for POP Regulation non-compliance? POP Regulation is enforced at member state level — each EU country sets its own penalties for violations. Common enforcement actions include product recall and market withdrawal, fines (which vary by member state from moderate to substantial), and in serious cases criminal liability. Market surveillance authorities coordinate through the RAPEX system to share information about non-compliant products across the EU. **Disclaimer:** Educational resource only.
