Restriction of Hazardous Substances is a mandate issued by the European Union, which restricts the use of six hazardous substances –– lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers –– in products sold within the EU. The restricted materials have been banned as they pollute landfills and contribute to occupational hazards in manufacturing and recycling.
