Updates to Confidential Status of Chemicals on the TSCA Inventory

For Release: April 29, 2021

Today, the Environmental Protection Agency (EPA) released a list of 390 chemicals expected to lose their confidential status and move to the public portion of the Toxic Substances Control Act (TSCA) Inventory, furthering the agency’s commitment to data transparency.  

The specific identities of these chemicals were reported as non-confidential during Chemical Data Reporting (CDR) cycles from the 2012, 2016, and/or 2020 reporting periods. In accordance with the CDR rule and with TSCA sections 8 and 14, EPA intends to update the TSCA Inventory listings for these chemicals to list the specific chemical identities on the public portion of the Inventory.   

Stakeholders with interest, questions, or concerns about this change in confidential status may contact the EPA staff listed on our webpage no later than May 14, 2021. The specific chemical identities of these 390 chemicals are expected to be included in the next routine publication of the public TSCA Inventory, anticipated in late summer 2021. 

View the list of 390 chemicals by accession number that EPA expects to disclose on the public TSCA Inventory.
