On July 29, 2025, the U.S. Environmental Protection Agency (EPA) issued final significant use rules (SNUR) for certain chemical substances, including graphene nanoplatelets (generic), that were the subject of premanufacture notices (PMN) and a Microbial Commercial Activity Notice (MCAN) and are also subject to an Order issued by EPA pursuant to the Toxic Substances Control Act (TSCA). 90 Fed. Reg. 35624. The SNURs require persons who intend to manufacture (including import) or process any of the chemical substances for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity. EPA notes that the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification, made an appropriate determination regarding that notification, and taken such actions as required by that determination. The final SNURs will be effective September 29, 2025.
