Legal Authority

    Section 201 of the Controlled Substances Act (CSA) (21 U.S.C. 811) 
authorizes the Attorney General, by regulation, to exempt from certain 
provisions of the CSA certain compounds, mixtures, or preparations 
containing a controlled substance, if he finds that such compounds, 
mixtures, or preparations meet the requirements detailed in 21 U.S.C. 
811(g)(3)(B).\1\ DEA regulations at 21 CFR 1308.23 and 1308.24 further 
detail the criteria by which the DEA Assistant Administrator may exempt 
a chemical preparation or mixture from certain provisions of the CSA. 
The Assistant Administrator may, pursuant to 21 CFR 1308.23(f), modify 
or revoke the criteria by which exemptions are granted and modify the 
scope of exemptions at any time.
---------------------------------------------------------------------------

    \1\ This authority has been delegated from the Attorney General 
to the DEA Administrator by 28 CFR 0.100, and subsequently 
redelegated to the Deputy Assistant Administrator pursuant to 28 CFR 
0.104 and Section 7 of the appendix to subpart R of part 0.
---------------------------------------------------------------------------

Exempt Chemical Preparation Applications Submitted Between July 1, 
2025, and March 31, 2026

    DEA received applications between July 1, 2025, and March 31, 2026, 
requesting exempt chemical preparation status detailed in 21 CFR 
1308.23. This publication addresses preparations through March 31, 
2026, that were not included in previous Federal Register notices, and 
it does not affect preparations that have been previously published. 
Additionally, this order corrects the listing of several preparations 
that were incorrectly listed in the previous Federal Register notice 
dated, March 20, 2026. The company name, product name, and/or form have 
been corrected. Pursuant to the criteria stated in 21 U.S.C. 
811(g)(3)(B) and in 21 CFR 1308.23, the Assistant Administrator has 
found that each of the compounds, mixtures, and preparations described 
in Chart I below is intended for laboratory, industrial, educational, 
or special research purposes and not for general administration to a 
human being or animal and either: (1) contains no narcotic controlled 
substance and is packaged in such a form or concentration that the 
packaged quantity does not present any significant potential for abuse; 
or (2) contains either a narcotic or non-narcotic controlled substance 
and one or more adulterating or denaturing agents in such a manner, 
combination, quantity, proportion, or concentration that the 
preparation or mixture does not present any potential for abuse and, if 
the preparation or mixture contains a narcotic controlled substance, is 
formulated in such a manner that it incorporates methods of denaturing 
or other means so that the preparation or mixture is not liable to be 
abused or have ill effects, if abused, and so that

[[Page 29507]]

the narcotic substance cannot in practice be removed.
    Accordingly, pursuant to 21 U.S.C. 811(g)(3)(B), 21 CFR 1308.23, 
and 21 CFR 1308.24, the Assistant Administrator has determined that 
each of the chemical preparations or mixtures generally described in 
Chart I below and specifically described in the application materials 
received by DEA is exempt, to the extent described in 21 CFR 1308.24, 
from application of sections 302, 303, 305, 306, 307, 308, 309, 1002, 
1003, and 1004 (21 U.S.C. 822-823, 825-829, and 952-954) of the CSA, 
and 21 CFR 1301.74, as of the date that was provided in the approval 
letters to the individual requesters.

Scope of Approval

    The exemptions are applicable only to the precise preparation or 
mixture described in the application submitted to DEA in the form(s) 
listed in this order and only for those above-mentioned sections of the 
CSA and the CFR. In accordance with 21 CFR 1308.24(h), any change in 
the quantitative or qualitative composition of the preparation or 
mixture, or change in the trade name or other designation of the 
preparation or mixture after the date of application requires a new 
application. The requirements set forth in 21 CFR 1308.24(b)-(e) apply 
to the exempted materials. In accordance with 21 CFR 1308.24(g), DEA 
may prescribe requirements other than those set forth in 21 CFR 
1308.24(b)-(e) on a case-by-case basis for materials exempted in bulk 
quantities. Accordingly, in order to limit opportunities for diversion 
from the larger bulk quantities, DEA has determined that each of the 
exempted bulk products listed in this order may only be used in-house 
by the manufacturer, and may not be distributed for any purpose, or 
transported to other facilities.
    Additional exempt chemical preparation requests received between 
January 1, 2026, and March 31, 2026, and not otherwise referenced in 
this order or in prior orders, may remain under consideration until DEA 
receives additional information required, pursuant to 21 CFR 
1308.23(d), as detailed in separate correspondence to individual 
requesters. DEA's order on such requests will be communicated to the 
public in a future Federal Register publication.
    DEA also notes that these exemptions are limited to exemption from 
only those sections of the CSA and the CFR that are specifically 
identified in 21 CFR 1308.24(a). All other requirements of the CSA and 
the CFR apply, including registration as an importer as required by 21 
U.S.C. 957.
