The Restriction of Hazardous Substances (RoHS) directive is one of the most important environmental compliance requirements for exporters selling electrical and electronic equipment to the European Union and other regulated markets. For Southeast Asian manufacturers producing aluminum products—whether tarot card display stands, industrial DIN rails, or electronic enclosures—understanding RoHS is not optional; it's a market access requirement.
What Does RoHS Actually Restrict? The directive limits ten specific substances to maximum concentration values of 0.1% by weight (1000 ppm), except for cadmium which is limited to 0.01% (100 ppm) [1]:
RoHS Restricted Substances and Maximum Limits
| Substance | Maximum Concentration | Common Sources in Aluminum Products |
|---|---|---|
| Lead (Pb) | 0.1% (1000 ppm) | Alloying element, solder, connectors |
| Mercury (Hg) | 0.1% (1000 ppm) | Switches, lighting components |
| Cadmium (Cd) | 0.01% (100 ppm) | Coatings, stabilizers |
| Hexavalent Chromium (Cr VI) | 0.1% (1000 ppm) | Surface treatments, corrosion protection |
| Polybrominated Biphenyls (PBB) | 0.1% (1000 ppm) | Flame retardants in plastics |
| Polybrominated Diphenyl Ethers (PBDE) | 0.1% (1000 ppm) | Flame retardants |
| Bis(2-ethylhexyl) phthalate (DEHP) | 0.1% (1000 ppm) | Plasticizers in cables |
| Butyl benzyl phthalate (BBP) | 0.1% (1000 ppm) | Plasticizers |
| Dibutyl phthalate (DBP) | 0.1% (1000 ppm) | Plasticizers |
| Diisobutyl phthalate (DIBP) | 0.1% (1000 ppm) | Plasticizers |
Why Aluminum Products Specifically Matter: Aluminum itself is not restricted under RoHS—in fact, it's considered one of the more environmentally friendly materials due to its recyclability. However, aluminum alloys often contain small amounts of lead (up to 0.4%) to improve machinability. This is where the exemption system becomes critical for exporters [2].
