Toxic Substances Control Act Inventory Status of Carbon Nanotubes

This document gives notice of the Toxic Substances Control Act (TSCA) requirements potentially applicable to carbon nanotubes (CNTs). EPA generally considers CNTs to be chemical substances distinct from graphite or other allotropes of carbon listed on the TSCA Inventory. Many CNTs may therefore be new chemicals under TSCA section 5. Manufacturers or importers of CNTs not on the TSCA Inventory must submit a premanufacture notice (PMN) (or applicable exemption) under TSCA section 5 where required under 40 CFR part 720 or part 723. In order to determine the TSCA Inventory status of a CNT, a manufacturer may submit to EPA a bona fide intent to manufacture or import under 40 CFR 720.25.
