What is RoHS Compliance?

Jesse Rothschild

Restriction of Hazard Substances (RoHS) compliant defines that the product conforms to the requirements of the European Union’s restriction on use of hazardous substances in electrical and electronics equipment’s directive,2002/95/EC (RoHS directive) which limits the content of the following elements:

  • Lead (Pb)
  • Mercury (Hg)
  • Cadmium (Cd)
  • Hexavalent Chromium (Cr6+)
  • Polybrominated biphenyls (PBB)
  • Polybrominated diphenyl ethers (PBDE)

Hexavalent chromium is used in primers, chrome coatings and chrome plating.

PBB and PBDE are used in plastics as flame retardants.

RoHS restricted substances appear in many electronic products in our industry: they can appear in

  • Cables: PVC (poly-vinyl chloride) cables such as power cables, Ethernet cables, IO cables, and serial cables
  • Enclosures: in paints, pigments, and metal parts
  • Circuit boards: solders, circuit board finishes, leads, interconnects such as serial connectors)
  • Power Supplies: Vinyl power cords, Batteries, power board circuit boards

RoHS is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC directive and a compliance certification is with respect to any homogenous components used in the product as shipped by its manufacturer.

The RoHS directive is vitally important for USAT’s clients in the European Union, global carrier partners such as Vodafone and AT&T, as well as North American enterprises with sales and offices in Europe. RoHS is also an environmental sustainability directive to reduce the hazardous materials in ‘hi-tech trash’ which USAT is proud that our suppliers support.
