The Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment 2002/95/EC[1] (commonly referred to as the Restriction of Hazardous Substances Directive or RoHS) was adopted in February 2003 by the European Union. The RoHS directive took effect on 1 July 2006, and is required to be enforced and become law in each member state. This directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of huge amounts of toxic e-waste.

Each European Union member state will adopt its own enforcement and implementation policies using the directive as a guide.

RoHS is often referred to as the lead-free directive, but it restricts the use of the following six substances:

Lead
Mercury
Cadmium
Hexavalent chromium (chromium xxx or Cr6+)
Polybrominated biphenyls (PBB)
Polybrominated diphenyl ether (PBDE)
PBB and PBDE are flame retardants used in several plastics.

In 2003, Toho had prepared ourselves to eliminate and avoid using the hazardous six substances in our product by replacing some of our equipment. Toho also produces only non-hazardous coils products in all of our production lines since 2005-1-1. Toho proudly announces the products are all comply to RoHS Directive 2002/95/EC.
