The scope seems to be more limited than that of EU RoHS and refers to products that are "directly used to facilitate the transmission, distribution, or control of electricity, or that use electrical power for arc welding, lighting, signalling protection and communication, or medical imaging, or electrical motors and generators".
The substance restrictions and maximum permitted concentration values, within homogeneous materials, are the same as EU RoHS although bill HR2420 does stipulate certain exemptions such as products or equipment designed with a voltage rating of 300 volts or above, fixed installations, certain medical equipment and electrical wire and cable products and accessories.
The bill also contains some, but not all, of the substance application exemptions currently within scope of EU RoHS, and under review at present as part of the so called "RoHS2" proposals.
It could be argued that this is not RoHS and, if it is, it is nothing like the scope of RoHS in the EU.
Restriction would apply to products manufactured after 1 July 2010, although it is not yet clear on how the date would be applied to products manufactured outside the US.
Guidelines for the testing of products must be published with one year of the Act's effective date.
