This document announces the Agency's receipt of new chemical submissions under the Toxic Substances Control Act (TSCA), including information about the receipt of a Premanufacture Notice (PMN), Significant New Use Notice (SNUN), Microbial Commercial Activity Notice (MCAN), and an amendment to a previously submitted notice; test information; a biotechnology exemption application; an application for a test marketing exemption (TME); and a notice of commencement of manufacture (defined by statute to include import) (NOC) for a new chemical substance. This document covers new chemical submissions that have passed an initial screening and, for PMNs, SNUNs and MCANs, were determined to be complete, during the period from May 1, 2026, to May 31, 2026, regardless of the initial submission date.

SUPPLEMENTARY INFORMATION:
I. Executive Summary
A. Does this action apply to me?
This action provides information that is directed to the public in general.
B. What is the Agency's authority for taking this action?
EPA is publishing this document in the
Federal Register
as required by sections 5 of the Toxic Substances Control Act (TSCA), 15 U.S.C. 2601et seq.,
and corresponding EPA regulations.
Under TSCA, a chemical substance may be either an “existing” chemical substance or a “new” chemical substance, see
https://www.epa.gov/chemicals-under-tsca.
Any chemical substance that is not on EPA's TSCA Inventory of Chemical Substances (TSCA Inventory) is classified as a “new chemical substance,” while a chemical substance that is listed on the TSCA Inventory is classified as an “existing chemical substance.” See TSCA section 3(2) and (11). For more information about the TSCA Inventory, see
https://www.epa.gov/tsca-/inventory.
Any person who intends to manufacture (including import) a new chemical substance for a non-exempt commercial purpose, or to manufacture or process a chemical substance in a non-exempt manner for a use that EPA has determined is a significant new use, is required by TSCA section 5 to provide EPA with a PMN, MCAN, or SNUN, as appropriate, before initiating the activity. EPA will review the notice, make a risk determination on the new chemical substance or significant new use, and take appropriate action as described in TSCA section 5(a)(3).
TSCA section 5(h)(1) authorizes EPA to allow persons, upon application and under appropriate restrictions, to manufacture a new chemical substance, or manufacture or process a chemical substance subject to a significant new use rule (SNUR) issued under TSCA section 5(a)(2), for “test marketing” purposes, upon a showing that the manufacture, processing, distribution in commerce, use, and disposal of the chemical substances will not present an unreasonable risk of injury to health or the environment. This is referred to as a test marketing exemption, or TME.
Premanufacture notification procedures for reviewing certain new microbial products of biotechnology are established in 40 CFR part 725. These pertain to MCANs and biotechnology exemptions, including TSCA experimental release applications (TERAs), TMEs for microorganisms, and Tier I and Tier II exemptions.
C. What action is the Agency taking?
This document provides notice of receipt and status reports for the covered period and certain submissions under TSCA section 5 and provides an opportunity to comment on this information. The Agency is providing information about the receipt of PMNs, SNUNs, MCANs, and amendments to a previously submitted notice; test information; biotechnology exemption applications under 40 CFR part 725; TME applications; NOCs for new chemical substances; and a periodic status report on chemical substances that are currently under EPA review or have recently concluded review.
D. What should I consider as I prepare my comments for EPA?
1.
Submitting CBI.
Do not submit CBI to EPA through
https://www.regulations.gov
or email. If you wish to include CBI in your comment, please follow the instructions at
https://www.epa.gov/dockets/commenting-epa-dockets#rules
and clearly mark the information that you claim to be CBI. In addition to one complete version of the comment that includes CBI, a copy of the comment without CBI must be submitted for inclusion in the public docket. Information marked as CBI will not be disclosed except in accordance with procedures set forth in 40 CFR parts 2 and 703.
A. What information is being provided in this document?
The tables in this document provide the following information on the TSCA section 5 submissions received by EPA during this period and determined to be
( printed page 47232)
completely consistent with 40 CFR 720.70(a).
Case number.
The EPA number assigned to the TSCA section is 5 submissions. Please note that a case number may be listed more than once in the table when the submission involves a subsequent amendment.
Chemical substance.
Name of the chemical substance, or generic name if the specific name is claimed as CBI.
Manufacturer.
Name of the submitting manufacturer, to the extent that such information is not subject to a CBI claim. The term “manufacturer” is defined by statute to include importer.
Use(s).
Potential uses identified by the manufacturer.
Received.
Date the submission was received by EPA.
Commencement.
Date of commencement provided by the submitter in the NOC.
Test information.
For test information received, the type of test information submitted to EPA is based on the attachment type and subtype data selected by the submitter.
B. What do the acronyms mean that are used in the tables?
As used in each of the tables, the following explanations apply:
(S) indicates that the information in the table is the specific information provided by the submitter.
(G) indicates that the information in the table is generic information because the specific information provided by the submitter was claimed as CBI.
C. How can I access other information about TSCA section 5 submissions?
Table 1 provides non-CBI information for the PMNs, SNUNs and MCANs received by EPA that have passed an initial screening and determined to be completely consistent with 40 CFR 720.70(a) during this period.
