Environmental Protection Agency (EPA).




EPA is updating the Toxics Substances Control Act (TSCA) Chemical Substance Inventory (TSCA Inventory) Master File to list 530 chemical substances as non-confidential on the TSCA Inventory that were previously listed as confidential. This action is necessary because these chemical substances no longer qualify for listing as confidential on the TSCA Inventory.


This update is effective July 22, 2009.

These chemical substances will be listed on public versions of the TSCA Inventory on or after August 3, 2009.

II. Background

The TSCA Inventory is a listing of all chemical substances manufactured, imported, or processed for a commercial purpose, which EPA was directed to establish and maintain pursuant to TSCA section 8. Since the initial TSCA Inventory was published, persons intending to manufacture or import a non-exempt chemical substance that is not on the TSCA Inventory have been required to submit premanufacture notices (PMNs) to the Agency under TSCA section 5; see 40 CFR part 720. For more information about the TSCA Inventory and related requirements, go to the TSCA Inventory webpage identified in Unit I.B.2.

The TSCA Inventory implementing regulations in 40 CFR part 710 provide that the manufacturer or importer may claim that the identity of a chemical substance in commerce is CBI. Confidential chemical identities are not listed on public versions of the TSCA Inventory. Chemical identities that are not confidential (i.e., where it is public knowledge that the chemical substance is in commerce) are listed on public versions of the TSCA Inventory.

III. Updating of the Public and Confidential TSCA Inventory Data

When reporting under the TSCA Inventory Update Rule (IUR at 40 CFR part 710), some manufacturers of these 530 chemical substances did not include any claim of confidentiality for the chemical identity of the chemical substance with the IUR submission. These chemical identities were previously listed as confidential on the TSCA Inventory. IUR regulations at 40 CFR 710.38(d) provide that where no claim of confidentiality accompanies IUR information at the time it is submitted to EPA, the Agency may make the information available to the public without further notice to the submitter. By submitting non-CBI IUR reports for previously confidential chemical identities, manufacturers make those chemical identities eligible for inclusion on public versions of the TSCA Inventory.

With this action, EPA is updating the TSCA Inventory Master File to reflect the public status of the identities of these chemical substances. The complete list of these chemical substances is provided in the docket at The updated public version of the TSCA Inventory will be available on or after August 3, 2009. For information on how to access the public (also referred to as the non-confidential) version of the TSCA Inventory, go to​opptintr/​newchems/​pubs/​invntory.htm.
