Abstract
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 also provides a periodic status report on the new chemical substances that are currently under EPA review or have recently concluded review. EPA is hereby providing notice of receipt of this information, as required by TSCA, and an opportunity to comment. 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 03/1/2026 to 03/ 31/2026 regardless of 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.
2601 et seq., and corresponding EPA regulations.
Under TSCA, a chemical substance may be either an ``existing''
chemical substance or a ``new'' chemical substance, see <a href="https://www.epa.gov/chemicals-under-tsca">https://www.epa.gov/chemicals-under-tsca</a>. 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 <a href="https://www.epa.gov/-inventory">https://www.epa.gov/-inventory</a>.
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
provides 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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> or email. If you wish to include CBI in your
comment, please follow the instructions at <a href="https://www.epa.gov/dockets/commenting-epa-dockets#rules">https://www.epa.gov/dockets/commenting-epa-dockets#rules</a> 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.
2. Tips for preparing your comments. When preparing and submitting
your comments, see the commenting tips at <a href="https://www.epa.gov/dockets/commenting-epa-dockets">https://www.epa.gov/dockets/commenting-epa-dockets</a>.
II. Background
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 completely consistent with 40 CFR 720.70(a).
<bullet> Case number. The EPA number assigned to the TSCA section 5
submissions. Please note that a case number may be listed more than
once in the table when the submission involves a subsequent amendment.
<bullet> Chemical substance. Name of the chemical substance, or
generic name if the specific name is claimed as CBI.
<bullet> 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.
<bullet> Use(s). Potential uses identified by the manufacturer.
<bullet> Received. Date the submission was received by EPA.
<bullet> Commencement. Date of commencement provided by the
submitter in the NOC.
<bullet> 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:
<bullet> (S) indicates that the information in the table is the
specific information provided by the submitter.
<bullet> (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?
EPA provides information on its website about cases reviewed under
TSCA section 5, including the PMNs, SNUNs, MCANs, and exemption
applications received; the date of receipt; the final EPA determination
on the submission; and the effective date of EPA's determination. See
<a href="https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca/pre-manufacture-notices">https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca/pre-manufacture-notices</a>. In addition, information EPA
receives about chemical substances under TSCA, including non-CBI new
chemical
