The Restriction of Hazardous Substances (RoHS) directive is one of the most critical compliance requirements for apparel accessories containing metal components. For Southeast Asian exporters selling on Alibaba.com, understanding RoHS regulations is no longer optional—it's a fundamental requirement for accessing European, North American, and increasingly Asian markets.
What is RoHS? RoHS restricts 10 specific substances in electrical and electronic equipment (EEE), but its principles have extended to apparel hardware including metal zipper pullers, buttons, rivets, buckles, and decorative elements. The directive limits lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four phthalates (DEHP, BBP, DBP, DIBP) to maximum concentration values of 0.1% by weight (1000 ppm), except cadmium which is limited to 0.01% (100 ppm) [4].
Why Aluminum Components Matter: Aluminum alloys are widely used in apparel hardware due to their lightweight properties, corrosion resistance, and aesthetic versatility. However, aluminum recycling and machining processes can introduce lead contamination. The RoHS directive includes specific exemption clauses for aluminum alloys, but these exemptions are undergoing significant changes in 2025-2026 that Southeast Asian exporters must understand immediately.
RoHS Lead Content Limits for Aluminum Alloys
| Exemption Category | Lead Limit | Application | Status 2026 |
|---|---|---|---|
| General RoHS Limit | 0.1% (1000 ppm) | All EEE products | Active |
| 6(b)-I Recycled Aluminum | 0.4% (4000 ppm) | Aluminum with recycled scrap content | Active until review |
| 6(b)-II Machining Exemption | 0.4% (4000 ppm) | Aluminum alloys for machining | Revoked Nov 2025, phase-out Jun 2027 |
| Proposed New Limit | 0.3% (3000 ppm) | Cast aluminum alloys | Under consideration |
