The EPA’s recently released paper, TSCA Inventory Status of Nanoscale Substances — General Approach, is important for developers of nanotechnologies. Nanomaterials that meet the Toxic Substances Control Act (TSCA) definition of “chemical substance” are subject to TSCA reporting requirements because they may exhibit properties different from the same substances in the bulk scale. A chemical substance means, in relevant part, “any organic or inorganic substance of a particular molecular identity.”
