I. What are the RoHS certification standards? (Conclusion)
What are the RoHS certification standards for consumer electronic hardware? RoHS (Restriction of Hazardous Substances) is an EU regulation restricting hazardous substances in electrical and electronic equipment. The current governing standard is Directive 2011/65/EU (effective July 21, 2011, replacing 2002/95/EC).
It limits the maximum content of 10 hazardous substances within homogeneous materials: Cadmium is limited to 0.01% by weight, while the others (Lead, Mercury, Hexavalent Chromium, PBB, PBDE, and four types of phthalates) are limited to 0.1% by weight.
It applies to all electrical and electronic equipment (AC ≤ 1000V / DC ≤ 1500V) as well as their cables and spare parts.
Compliance is achieved through internal production control (Module A), technical documentation, signing a Declaration of Conformity (DoC), and affixing the CE mark.
It is not an optional “certification certificate” but a mandatory market access requirement for the EU—products exceeding these limits are prohibited from being placed on the market.
II.
The 10 Restricted Substances
What are the RoHS certification standards for consumer electronic hardware?
It is important to remember the 10 restricted substances.
The first batch of six (effective since 2006): Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (Cr6+), Polybrominated Biphenyls (PBB), and Polybrominated Diphenyl Ethers (PBDE). The second batch, added on July 22, 2019, consists of four phthalates: DEHP, BBP, DBP, and DIBP.
Limits are calculated based on “homogeneous materials” (uniform materials or composite materials that cannot be mechanically separated—such as plastic monitor casings, copper wiring, and solder joints): Cadmium is limited to 0.01% (100 mg/kg), while all other substances are limited to 0.1% (1,000 mg/kg).
Note that restrictions on phthalates in toys are governed separately by Entry 51 of Annex XVII to the REACH Regulation.
Before export, submit samples to a third-party laboratory for analysis according to the IEC 62321 series of standards;
the resulting component report will indicate whether compliance has been achieved.
III. Scope and Exemptions
What are the RoHS certification standards for consumer electronic hardware?
The scope is broad, and exemptions require close attention.
Scope: Applies to all Electrical and Electronic Equipment (EEE)—including home appliances, televisions, mobile phones, battery-powered tools, watches, vending machines, and textiles with battery-operated LED lights—provided they require an electric current or electromagnetic field to perform a function and operate at voltages of AC ≤ 1000V or DC ≤ 1500V.
Since July 2019, an “open-ended catch-all category” has extended the ban to cover all EEE, as well as cables and spare parts.
Exclusions (Not Applicable): Weapons, aerospace equipment, large-scale stationary industrial tools, fixed installations (such as generators), and photovoltaic panels.
Exemptions: Annexes III and IV list temporary exemptions (e.g., lead in electronic ceramic components, lead in high-melting-point solder, and mercury in fluorescent lamps); this list is subject to periodic updates based on technological progress and includes expiration dates.
Always verify the currently valid exemption list before export—expired exemptions are no longer applicable.
IV.
How to Ensure Compliance
What are the RoHS certification standards for consumer electronic hardware?
Four steps to compliance.
I. Identify restricted substances: Cross-reference the Bill of Materials (BOM) to pinpoint high-risk components (e.g., lead in solder, phthalates in PVC cables, polybrominated flame retardants, hexavalent chromium in plating). II. Testing and assessment: Conduct sample preparation and analysis (XRF screening followed by chemical testing) in accordance with the IEC 62321 series; follow a three-step assessment process covering materials, suppliers, and the final product (noting that manufacturing processes like soldering can also introduce lead). III. Compile technical documentation: Prepare technical files (including material/supplier/process assessments, test reports, and Declarations of Conformity) in accordance with the harmonized standard EN IEC 63000:2018 to demonstrate compliance. IV. Internal Production Control (Module A), sign the Declaration of Conformity (DoC), and affix the CE mark: EU regulations require technical documentation to be retained for at least 10 years for inspection purposes.
Note that eliminating lead from solder is a primary challenge for RoHS compliance; using lead-free solder (such as SAC305) can significantly reduce lead-related risks.
V. CE Marking and other markets: What are the RoHS certification standards for consumer electronics hardware?
How does RoHS relate to CE marking and other markets?
Regarding CE: RoHS is part of the CE marking framework (affixing the CE mark implies a declaration of RoHS compliance); EU CE certification covers directives such as LVD, EMC, RoHS, and RED, with RoHS compliance demonstrated via EN IEC 63000 technical documentation and a DoC. Regarding WEEE: RoHS restricts hazardous substances, while WEEE governs waste disposal and recycling; the two operate in parallel, with WEEE requiring manufacturers to register in the EU and participate in recycling programs.
Regarding other markets: Global regulations vary—examples include China RoHS (GB/T 26572-2011 limits plus a national voluntary certification scheme), California Proposition 65 (USA), and regulations in South Korea and the UK. Specific substances and limits may differ (e.g., Saudi Arabia’s SASO RoHS does not include phthalates).
When targeting global markets, adopt a “one table, multiple records” approach: verify substance lists and limits item-by-item against target market requirements rather than relying on a single EU-based standard for all regions.
Conclusion
What are the RoHS certification standards for consumer electronic hardware?
In short: EU Directive 2011/65/EU restricts ten hazardous substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE, DEHP, BBP, DBP, and DIBP), with concentration limits in homogeneous materials set at 0.01% for cadmium and 0.1% by weight for the others. It applies to all EEE (AC ≤ 1000V / DC ≤ 1500V), including cables and spare parts; exclusions include military equipment, aerospace applications, large-scale stationary industrial tools, and photovoltaic panels, among others, with the exemption list subject to ongoing updates.
Compliance involves: identifying high-risk components in the Bill of Materials (BOM) → IEC 62321 testing (XRF + chemical analysis) → EN IEC 63000 technical documentation → internal production control, signing the Declaration of Conformity (DoC), and affixing the CE mark, with records retained for 10 years.
RoHS is part of the CE framework and runs parallel to WEEE; regulations in regions like China, California, and South Korea differ and must be verified on a market-by-market basis.
Transitioning to lead-free solder is the primary challenge;
compliance begins at the BOM stage.
