The Restriction of Hazardous Substances (RoHS) directive is one of the most critical compliance requirements for electronics exporters selling on Alibaba.com. Originally adopted by the European Union in 2003 and recast in 2011 as Directive 2011/65/EU, RoHS restricts the use of specific hazardous materials in electrical and electronic equipment [1].
For Southeast Asian merchants looking to export electronics through Alibaba.com, understanding RoHS is not optional—it's a market access requirement. The directive applies to a wide range of products including consumer electronics, industrial equipment, medical devices, and monitoring instruments. Non-compliance means your products cannot carry the CE marking and cannot be legally sold in the EU market.
RoHS 10 Restricted Substances and Thresholds
| Substance | Category | Maximum Threshold | Common Applications | Health Impact |
|---|---|---|---|---|
| Cadmium (Cd) | Category 1 | <100 ppm | Batteries, pigments, stabilizers | Carcinogenic, kidney damage |
| Lead (Pb) | Category 2 | <1000 ppm | Solder, cables, batteries | Neurotoxic, developmental issues |
| Mercury (Hg) | Category 2 | <1000 ppm | Switches, lamps, batteries | Neurotoxic, kidney damage |
| Hexavalent Chromium (Cr VI) | Category 2 | <1000 ppm | Metal plating, corrosion protection | Carcinogenic, skin ulcers |
| Polybrominated Biphenyls (PBB) | Category 2 | <1000 ppm | Flame retardants in plastics | Endocrine disruption |
| Polybrominated Diphenyl Ethers (PBDE) | Category 2 | <1000 ppm | Flame retardants in circuit boards | Thyroid disruption |
| Bis(2-ethylhexyl) phthalate (DEHP) | Category 2 | <1000 ppm | PVC cable insulation | Reproductive toxicity |
| Butyl benzyl phthalate (BBP) | Category 2 | <1000 ppm | PVC flooring, cables | Reproductive toxicity |
| Dibutyl phthalate (DBP) | Category 2 | <1000 ppm | Adhesives, sealants | Reproductive toxicity |
| Diisobutyl phthalate (DIBP) | Category 2 | <1000 ppm | PVC, coatings | Reproductive toxicity |
The distinction between Category 1 (cadmium) and Category 2 (all others) is critical for testing protocols. Cadmium's stricter threshold reflects its higher toxicity. When suppliers claim RoHS compliance, they must demonstrate that every homogeneous material in the product meets these thresholds—not just the product as a whole.
