The EU RoHS Directive (full title: "Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment") is the EU's core environmental regulation for electrical and electronic equipment (EEE), aimed at restricting the use of hazardous substances in products and reducing harm to the environment and human health. Below is a detailed analysis of its core content and latest developments:

I. Regulatory Evolution and Versions

II. Controlled Hazardous Substances and Limit Values

As of 2025, RoHS 3.0 restricts the following 10 substances, with content in homogeneous materials required to meet the following standards:


  1. Heavy Metals

    • Lead (Pb) ≤ 0.1% (1000 ppm)

    • Mercury (Hg) ≤ 0.1%

    • Cadmium (Cd) ≤ 0.01% (100 ppm)

    • Hexavalent Chromium (Cr⁶⁺) ≤ 0.1%

  2. Flame Retardants

    • Polybrominated Biphenyls (PBB) ≤ 0.1%

    • Polybrominated Diphenyl Ethers (PBDE) ≤ 0.1%

  3. Phthalates

    • DEHP (Di(2-ethylhexyl) phthalate) ≤ 0.1%

    • BBP (Butyl benzyl phthalate) ≤ 0.1%

    • DBP (Dibutyl phthalate) ≤ 0.1%

    • DIBP (Diisobutyl phthalate) ≤ 0.1%


Note: In 2025, the EU proposed adding Tetrabromobisphenol A (TBBP-A) and Medium-Chain Chlorinated Paraffins (MCCPs), but since REACH regulations already cover related controls, they were ultimately not included in the RoHS list.chinawto.mofcom.gov.cn

III. Scope of Applicable Products

RoHS applies to ten categories of electrical and electronic equipment and components, including but not limited to:chinawto.mofcom.gov.cn


  1. Large Household Appliances(e.g., refrigerators, washing machines)

  2. Small Household Appliances(e.g., hair dryers, vacuum cleaners)

  3. IT and Telecommunications Equipment(e.g., computers, mobile phones)

  4. Consumer Electronics(e.g., televisions, audio equipment)

  5. Lighting Equipment(e.g., LED lamps)

  6. Electrical and Electronic Tools(e.g., electric drills)

  7. Toys, Leisure and Sports Equipment

  8. Medical Devices(e.g., CT scanners, electrocardiographs)

  9. Industrial Monitoring and Control Equipment

  10. Automatic Dispensers (Vending Machines)


Newly Added Control: From 2025, electronic cigarettes containing circuits are explicitly included in the RoHS scope (classified under PACK 13), requiring testing for migration levels of cadmium, lead, and other substances.

IV. Exemption Clauses and Latest Revisions

RoHS allows exemptions for specific applications, subject to periodic review. Key exemption updates from 2023 to 2025 include:


  1. Mercury Exemptions

    • Revised July 2023: Mercury is permitted in melt pressure sensors for capillary rheometers operating at temperatures above 300°C and pressures above 1000 bar, valid until the end of 2025.Shandong Provincial Department of Commerce

  2. Lead Exemptions

    • Lead as an alloying element in steel, aluminum, and copper alloys, with maximum concentrations of 0.35% (steel), 0.4% (aluminum), and 4% (copper), valid until December 31, 2026.fairtrade.sww.sh.gov.cn

    • Lead in high-melting-temperature solders (e.g., alloys with lead content > 85%), valid until December 31, 2027.fairtrade.sww.sh.gov.cn

    • January 2025 Draft:


Exemption Applications: Enterprises must submit technical justification to the European Commission demonstrating that alternatives are scientifically or technically impracticable.Shandong Provincial Department of Commerce

V. Certification Process and Enforcement Requirements

  1. Self-Declaration and CE Marking
    Manufacturers must ensure product compliance with RoHS requirements. After passing third-party testing (e.g., XRF screening + chemical analysis confirmation), they must sign a Declaration of Conformity (DoC) and affix the CE mark.

  2. Technical Documentation
    Product design drawings, bills of materials (BOM), supplier compliance declarations, and other documentation must be retained for inspection by EU market surveillance authorities.

  3. Testing Method Upgrades
    From 2025, high-precision instruments such as ICP-MS (Inductively Coupled Plasma Mass Spectrometry) are recommended, with detection limits as low as 0.1 ppm, to meet more stringent compliance requirements.


Consequences of Non-Compliance: Products may be recalled, fined (e.g., the Netherlands once fined a company 17 million euros for cadmium-containing game consoles), or even expelled from the EU market.

VI. Differences from REACH Regulation

VII. Latest Developments and Industry Impact

  1. Supply Chain Traceability: The EU requires enterprises to provide complete supply chain hazardous substance data to ensure raw material compliance.

  2. Alignment with Chinese Regulations: China RoHS 2.0 (GB/T 26572-2024) is synchronized with EU standards, with mandatory enforcement from September 2025, covering 11 product categories.

  3. Technical Challenges: Testing for phthalates requires penetrating coatings or material surfaces; enterprises need to optimize processes to avoid migration exceedances.

VIII. Compliance Recommendations

  1. Supply Chain Management: Prioritize suppliers with RoHS certification and require Material Safety Data Sheets (MSDS).

  2. Testing Strategy: For complex products (e.g., medical devices), adopt tiered testing with emphasis on high-risk components (e.g., circuit boards, solders).

  3. Exemption Tracking: Regularly review official EU announcements and promptly update exemption clause validity periods and scope of application.fairtrade.sww.sh.gov.cn

Summary

The RoHS Directive drives green transformation in the electronics industry by restricting hazardous substances. Enterprises must continuously monitor regulatory developments, optimize supply chain management and testing processes to meet the stringent requirements of the EU market.
