The Chemical Data Reporting (CDR) rule, under section 8(a) of the Toxic Substances Control Act (TSCA), requires manufacturers (including importers) to provide the EPA with information, including processing and use information, on chemical substances that they manufacture (including import) above threshold production volumes. The information is collected every four years and the production volume threshold for reporting a chemical substance is generally 25,000 pounds for a specific reporting year. Collecting the information every four years assures that the EPA and, with respect to non-confidential data, the public, have access to information on chemicals that are being domestically produced or imported above threshold quantities. Before the next reporting period of 2020, the EPA will be examining the reporting requirements to better align the reporting with Agency needs. This may involve changing features of the rule such as the frequency of reporting, the reporting of processing and use information, reporting parent company information, and other changes to the rule related to the recent amendment of TSCA by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, other than any amendments pursuant to TSCA section 8(a)(3)(C) or 8(a)(6). Amendments under the latter two provisions would proceed by separate actions.
