Is there an environmental regulation in the US similar to RoHS in Europe? I understand there is an HR2420, is this mandatory?

I know of two

U.S. Rep. Michael Burgess, D-Texas, introduced a bill in Congress on May 4, 2009, H.R. 2420, which amends the Toxic Substances Control Act (TSCA) of 1976 to ensure that certain hazardous substances used in electrical equipment are subject to uniform federal control regulations, both in the U.S. states and in foreign trade. hazardous substances in the U.S. states and in foreign trade to ensure the implementation of uniform federal control regulations for certain hazardous substances used in electrical equipment.

H.R. 2420: The Electrical Equipment Design for Environmental Excellence Act (EDEE Act) would standardize electrical and electronic equipment restriction regulations across all U.S. states at the federal level.

Restricted Substances:

The Act prohibits the presence of "lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs)," which are six toxic and hazardous substances contained in electrical and electronic products manufactured on July 1, 2010, from being used in the manufacture of electrical and electronic equipment.

Limits: The limits are consistent with EU RoHS.

Restriction of substances: "The Act prohibits the July 1, 2010 production of electrical and electronic products containing" lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers six toxic and hazardous substances.

California's Electronic Waste Recycling Act, SB 20, and its amendment, SB 50, provide for the recycling of electrical and electronic equipment and the restriction of material requirements.

2007.1.1 officially implemented.

SB 20/SB 50 stipulates that certain electronic equipment manufactured after January 1, 2007, with four heavy metals (lead, cadmium, mercury and hexavalent chromium) exceeding the limits of the European Union's RoHS Directive, will not be allowed to enter the California market.
