RoHS EU Restriction of Hazardous Substances Directive
Compliance Guide for Electrical, Electronic Equipment & Components
RoHS (Restriction of Hazardous Substances) is a mandatory environmental regulation established by the European Union to restrict the use of specific hazardous substances in electrical and electronic equipment, helping protect human health and promote environmental sustainability. Electronic products placed on the EU market must comply with the applicable RoHS requirements.
Key Highlights
- RoHS 2.0 restricts 10 hazardous substances, including heavy metals, brominated flame retardants, and phthalates.
- The requirements apply to electrical and electronic equipment, medical devices, monitoring equipment, cables, and related components placed on the EU market.
- Products may require chemical analysis and XRF screening by third-party testing organizations such as SGS or TÜV SÜD, together with complete technical documentation.
Core Restrictions: 10 Hazardous Substances and Maximum Concentration Values
RoHS requirements, commonly referring to RoHS 2.0 / Directive 2011/65/EU and its amendments, restrict the maximum concentration of the following 10 hazardous substances in homogeneous materials:
- Heavy Metals (Maximum ≤ 0.1% / 1000 ppm): Lead (Pb), Mercury (Hg), Hexavalent Chromium (Cr6+)
- Heavy Metals (Maximum ≤ 0.01% / 100 ppm): Cadmium (Cd)
- Brominated Flame Retardants (Maximum ≤ 0.1% / 1000 ppm): Polybrominated Biphenyls (PBB), Polybrominated Diphenyl Ethers (PBDE)
- Phthalates / Plasticizers (Maximum ≤ 0.1% / 1000 ppm):
- Bis(2-ethylhexyl) Phthalate (DEHP)
- Benzyl Butyl Phthalate (BBP)
- Dibutyl Phthalate (DBP)
- Diisobutyl Phthalate (DIBP)
Scope of Application and Supply Chain Compliance
Applicable Products
The requirements apply to electrical and electronic equipment, medical devices, monitoring and control equipment, household appliances, cables, and related components placed on the EU market.
Compliance Marking and Declaration of Conformity
Relevant products must be supported by appropriate technical documentation and, where applicable under the CE conformity framework, bear the required CE marking and be accompanied by an EU Declaration of Conformity (DoC).
Testing Methods and Test Reports
Manufacturers commonly engage third-party testing organizations such as TÜV SÜD Taiwan or SGS to perform XRF screening and detailed chemical analysis on raw materials and finished products. Qualified test reports can then be incorporated into the technical documentation to help ensure environmental and regulatory compliance throughout the supply chain.
