This bill, known as the "Alan Reinstein Ban Asbestos Now Act of 2025," seeks to amend the Toxic Substances Control Act (TSCA) by implementing a comprehensive ban on commercial asbestos. Effective upon its enactment, the legislation prohibits the manufacture, processing, use, and distribution in commerce of commercial asbestos and any mixtures or articles containing it. The bill specifically defines "commercial asbestos" to include various asbestiform varieties like chrysotile, crocidolite, and amosite, among others, when extracted and processed for commercial value. It clarifies that the prohibition does not apply to existing installations or to the distribution of materials solely for disposal. The bill includes a temporary, limited exemption for the chlor-alkali industry , allowing facilities in operation on the enactment date to use asbestos fibers for manufacturing diaphragms and to use asbestos diaphragms in production until January 1, 2030. Additionally, the President may grant national security exemptions for up to three years, extendable once, if no feasible alternative exists and the exemption is necessary for national security interests. Such exemptions must include terms to reduce exposure and are subject to publication in the Federal Register, with an exception for sensitive information. The legislation also specifies that it applies only to chemical substances under TSCA and does not affect other regulations concerning asbestos, such as those for cosmetics, nor does it apply to materials where asbestos is present solely as an impurity.
