EPA’s February 2019 update to the Toxic Substances Control Act Inventory indicates whether a chemical is being actively manufactured, processed, or imported in the U.S. According to EPA, less than half of the total number of chemicals on the current TSCA Inventory—47 percent, or 40,655 of the 86,228 chemicals on the list—are currently in commerce. The updated chemicals list designates which substances are active in U.S. commerce based on information provided to EPA by chemical manufacturers, processors, and importers from August 2017 through October 2018. These stakeholders provided information on which chemicals were manufactured, imported, or processed in the U.S. during the ten years leading up to June 21, 2016. The agency states that this updated information will help EPA focus its risk evaluation efforts on chemicals that are still on the market. “As recently as 2018, the TSCA Inventory showed over 86,000 chemicals available for commercial production and use in the U.S.,” EPA’s press release reads. “Until this update, it was not known which of these chemicals on the TSCA Inventory were actually in commerce.” Instructions for accessing the TSCA Inventory are available on EPA's website.
