International Traffic in Arms Regulations: U.S. Munitions List 
Targeted Revisions

AGENCY: Department of State.

ACTION: Final rule; interim final rule adopted with changes.

-----------------------------------------------------------------------

SUMMARY: The Department of State (the Department) amends the 
International Traffic in Arms Regulations (ITAR) to remove from the 
U.S. Munitions List (USML) items that no longer warrant inclusion, add 
to the USML items that warrant inclusion, and clarify certain entries. 
With these amendments, the Department also updates the interim final 
rule it published on January 17, 2025. In addition, the Department is 
adding a new license exemption for certain activities related to 
unmanned underwater vehicles described in the exemption.

DATES: As of August 27, 2025, amendatory instruction number three in 
the interim final rule published at 90 FR 5594 on January 17, 2025, is 
withdrawn.
    Effective date: This rule is effective September 15, 2025.

FOR FURTHER INFORMATION CONTACT: Mr. Chris Weil, Office of Defense 
Trade Controls Policy, Department of State, email 
[email protected]; SUBJECT: ITAR Amendment--RIN 1400-AF42.

SUPPLEMENTARY INFORMATION: The Department of State's Directorate of 
Defense Trade Controls (DDTC) administers the ITAR (22 CFR parts 120 
through 130) to, among other things, regulate the export, reexport, 
retransfer, and temporary import of defense articles and defense 
services described on the USML at ITAR Sec.  121.1. Items not subject 
to the ITAR or to the exclusive licensing jurisdiction of any other 
department or agency of the U.S. Government are subject to the Export 
Administration Regulations (EAR; 15 CFR parts 730 through 774), which 
include the Commerce Control List (CCL) in Supplement No. 1 to part 
774. The EAR is administered by the Bureau of Industry and Security 
(BIS), U.S. Department of Commerce. This rule does not modify the list 
of defense articles and defense services controlled for purposes of 
permanent import by the Attorney General, as enumerated on the U.S. 
Munitions Import List (USMIL) at 27 CFR 447.21.
    Section 38 of the Arms Export Control Act (AECA; 22 U.S.C. 2778), 
the authority from which the ITAR is derived, requires periodic review 
to determine what articles and services, if any, no longer warrant 
designation on the USML at ITAR Sec.  121.1. In maintaining the USML, 
DDTC's Office of Defense Trade Controls Policy (DTCP) identifies 
articles and services for review for addition to or removal from the 
USML, or for clarification on how they are described on the USML, 
through a variety of methods, including public feedback and interagency 
consultations, commodity jurisdiction reviews, advisory opinions, and 
technology monitoring. The Department maintains the USML such that it 
comprises those defense articles or defense services that provide a 
critical military or intelligence advantage or, in the case of weapons, 
have an inherently military function. The Department, informed by 
consultations with its interagency partners, determined that the 
additional items this rule designates on the USML warrant ITAR control 
and those articles it removes from the USML no longer do. This rule 
also amends certain language that describes items on the USML to 
provide additional clarity to the regulatory text. Although it is not 
seeking public comment in this final rule, the Department nonetheless 
welcomes submissions from members of the public identifying specific 
descriptions of items that, in their view, the Department should 
consider revising, removing, or adding to the USML in future 
rulemaking. As members of the public are often

[[Page 41779]]

uniquely positioned to provide information that can assist the 
Department in its review of the USML, including technology 
developments, commercial use of defense technology, and industry 
interpretation and application of particular terminology, the 
Department accepts the submission of such views to help inform its 
monitoring of the technology frontier via [email protected].
    On January 17, 2025, the Department published an interim final rule 
(the IFR) in the Federal Register at 90 FR 5594 amending the ITAR to 
remove from the USML items that no longer warrant inclusion, add to the 
USML items that warrant inclusion, and clarify certain entries. That 
rule included a request for comments on the revisions therein and was 
scheduled to go into effect on September 15, 2025. Having reviewed and 
considered the comments submitted in response to the IFR, and having 
separately considered other changes to the USML based on its ongoing 
assessments and periodic review of the USML, the Department is 
publishing this final rule, which revises the ITAR and the IFR.
    In summary, in response to feedback the Department received from 
the IFR, and based on other assessments and the discretion afforded it, 
the Department is making some alterations to the changes implemented 
therein and making certain additional changes to the ITAR with 
explanations provided in the section of this preamble titled 
``Responses to Comments Received.'' Those changes include removing 
lead-free birdshot, Global Navigation Satellite Systems (GNSS) anti-
spoofing and GNSS anti-jam systems, and certain anti-jam antennas from 
the USML. They also include adding a new exemption for some of the 
underwater vessels the IFR added to USML Category XX(a)(10) that, 
although they provide a critical military or intelligence advantage 
such that they warrant description on the USML, the Department assesses 
are also highly suitable for scientific research and specific 
commercial operations.

Regulatory Implementation

    The Department is, with this final rule, superseding and replacing 
the amendments to Sec.  121.1 that were scheduled to be made on 
September 15, 2025 by the IFR. For administrative purposes and to 
conform to procedures of the Office of the Federal Register (OFR), the 
desired replacements made by this rule are procedurally accomplished by 
withdrawing the IFR's amendatory instructions for Sec.  121.1 (i.e., 
the IFR's amendatory instruction number three) in the preceding 
``Date'' section heading of this rule, and having the amendatory 
instructions for Sec.  121.1 made by this rule (i.e., this final rule's 
amendatory instruction number three) take effect on the same date, 
September 15, 2025. Because the changes to the list of definitions in 
the updated Sec.  121.0 are implemented by providing new regulatory 
language in amendatory instruction number two, in both the IFR and this 
final rule, and both sets of regulatory language are scheduled to take 
effect on the same effective date, the corresponding revisions made by 
this final rule will take effect on September 15, 2025. More 
specifically, OFR will implement both revision instructions on the 
effective date in the order in which they were originally published in 
the Federal Register. Thus, the amendatory instructions in this final 
rule reflect all relevant amendatory instructions from both this final 
rule and the IFR that will be implemented on the September 15, 2025 
effective date. In summary, all of this is done so that the reader does 
not have to combine two separate sets of sequential amendments and 
instead can more easily view the changes made in one place and in one 
rule.

Responses to Comments Received

22 CFR 121.0

    In response to the IFR, one commenter raised concerns that having 
an Active Electronically Scanned Array (AESA) radar is insufficient to 
distinguish an advanced aircraft from other less sensitive military 
aircraft within the definition of ``foreign advanced military 
aircraft'' in Sec.  121.0. The Department notes both the IFR and this 
final rule specify that having an AESA fire control radar is an 
advanced military capability meeting the definition's criteria. 
Aircraft that only have AESA radar not associated with a fire control 
system do not meet the AESA fire control radar criterion in this 
definition. Additionally, in response to informal feedback, the 
Department is amending the definition's criteria to clarify that 
``integrated'' applies to both ``electronic warfare (EW) systems'' and 
``signature management'' systems. Integrated signature management is 
included in the overall design of the aircraft, while integrated EW 
systems do not include federated (i.e., standalone) EW systems. The 
Department is also reformatting the foreign advanced military aircraft 
definition for clarity and ease of use and adding the definite article 
``the'' to certain definitions for clarity.

USML Category II

    A portion of the IFR's amendatory instruction that this rule 
withdraws was included in the IFR to correct a typographical error in 
Note 2 to paragraph (d) of Category II. As that error has since been 
corrected through separate administrative action, State is not 
reissuing that portion of the amendatory instruction in this rule.

USML Category III

    Separate from the IFR, the Department is taking this opportunity to 
revise paragraph (d)(6) of USML Category III to exclude common lead-
free birdshot ammunition, even if it is made from tungsten or steel and 
thus has a core produced from tungsten or steel. The Department does so 
consistent with its assessment that such projectiles do not provide a 
critical military or intelligence advantage and do not have an 
inherently military function. The Department of Commerce's Export 
Administration Regulations classify such ammunition as EAR99. 
Consistent with the Department's assertion of the military or foreign 
affairs function exception to the notice-and-comment requirements of 
the Administrative Procedure Act (see the ``Regulatory Analyses'' 
section of this preamble), the Department did not publish a rule 
proposing this change but still welcomes relevant views at 
[email protected].

USML Category IV

    One commenter observed that the Department's addition of a separate 
paragraph (c)(2) in USML Category IV implies improvised explosive 
devices (IEDs) are not described in paragraph (a) or (b). As the 
commenter notes, IEDs may be produced from articles described on the 
USML or articles not described on the USML. Consequently, some IEDs 
contain defense articles and some do not. The Department affirms that 
IEDs are not described on the USML solely because they are IEDs. 
Defense articles used as IED components remain defense articles subject 
to ITAR Sec.  120.11(c).
    The same commenter suggested the Department add IEDs to paragraph 
(a)(9), which currently describes mines. The Department declines to 
enumerate IEDs here, or elsewhere on the USML, for the same reasons 
they are not described in paragraph (a)(6), which describes bombs. 
Although some efforts to regulate the export of common IED precursor 
materials to high-risk areas have been temporarily implemented by other 
agencies in the past, by definition, IEDs are improvised from available

[[Page 41780]]

materials and the manufacture, production, and use of IEDs is regulated 
via other legal authorities, including title 18 of the U.S. Code (see, 
e.g., 18 U.S.C. 842, 2332, and 2339). The same commenter suggested that 
paragraph ML4.a. of the 2024 Wassenaar Arrangement Munitions List 
(WAML) explicitly controls ``explosive devices,'' including IEDs. 
However, the Department notes the explosive devices described in that 
paragraph are any of the following that are ``specially designed for 
military use'': ``Bombs, torpedoes, grenades, smoke canisters, rockets, 
mines, missiles, depth charges, demolition-charges, demolition-devices, 
demolition-kits, `pyrotechnic' devices, cartridges, submunitions 
therefor and simulators.''
    Additionally, the commenter recommended the Department not describe 
IED and mine disposal and protection equipment on the USML. To this 
end, the commenter recommended adding a note to paragraph (c) to state 
that remotely operated vehicles (ROVs) and disruptors specially 
designed or modified for the disposal of IEDs, and specially designed 
components and accessories therefor, are subject to the EAR under 
Export Control Classification Number (ECCN) 1A006 on the CCL. The 
Department affirms that some ROVs and disruptors for IEDs are not 
described in the new paragraph (c)(1) or (2) created by the IFR. For 
example, an IED disruptor that disables IEDs by use of a water lance 
(i.e., a high-velocity water stream that can rapidly disrupt or damage 
the target electronics) is not specially designed for the handling, 
control, activation, monitoring, detection, protection, discharge, or 
detonation of IEDs. As these items are not currently described in 
paragraph (c), the Department declines to add language removing them.

USML Category V

    The Department is updating paragraph (c)(2) of USML Category V to 
add a second Chemical Abstract Service (CAS) Registry Number for 
pentaborane, consistent with those provided on the WAML. The Department 
notes CAS numbers indicated on the USML may not cover all substances 
and mixtures described in the associated USML entries. As explained in 
Note 2 to Category V, CAS numbers are only provided as examples.

USML Category VIII

    One commenter stated the inclusion of the AESA fire control radar 
criterion in the definition of foreign advanced military aircraft will 
result in the ``inadvertent inclusion of thousands of minor parts and 
components'' in USML Category VIII(h)(1) that the commenter believes 
should remain on the CCL. The Department assesses the scenario 
described is a misinterpretation of the changes to paragraph (h)(1), as 
that paragraph does not include a catch-all control for parts used 
exclusively in foreign advanced military aircraft. Instead, by adding 
paragraph (h)(1)(iii), the Department is reinforcing the existing 
catch-all control for aircraft described in paragraphs (h)(1)(i) and 
(ii). This supports U.S. industry participation in foreign advanced 
military aircraft programs by ensuring the reuse of current paragraph 
(h)(1) parts does not release those parts from the USML, which helps 
enable more favorable licensing adjudications for such repurposing of 
existing U.S. parts.
    In alignment with the President's announcement, on March 22, 2025, 
that the U.S. Air Force's Next Generation Air Dominance Platform has 
been designated as the F-47, the Department is adding the F-47 to the 
list of aircraft in paragraph (h)(1)(i) of USML Category VIII. While 
the F-47 is currently enumerated in paragraphs (a)(2) and (f) of USML 
Category VIII, the catch-all control for its specially designed parts, 
components, accessories, and attachments is currently in paragraph (f), 
based on the aircraft's developmental status. Adding the F-47 to the 
list of aircraft in (h)(1)(i) ensures those items remain described on 
the USML after the F-47 enters production. The F-47 will be the most 
advanced, lethal, and adaptable fighter aircraft ever developed, and 
the Department assesses the specially designed items this change adds 
to paragraph (h)(1) will continue to provide a critical military or 
intelligence advantage after the F-47 enters production.
    Additionally, the Department is clarifying that, while it 
considered removing articles specially designed for parts, components, 
accessories, and attachments used exclusively in U.S. Government 
technology demonstrators from paragraph (h)(29) in the IFR, it elects 
not to do so at this time. The Department is also removing an 
extraneous use of the word ``this'' from paragraph (h)(29).
    Furthermore, consistent with the regulatory text presented in the 
IFR, the Department notes it expanded paragraph (h)(29) in the IFR to 
also describe articles specially designed for foreign advanced military 
aircraft described in paragraph (a)(1), (2), or (3) or developmental 
aircraft described in paragraph (f). This expansion does not extend to 
articles specially designed only for parts, components, accessories, 
and attachments not described in paragraph (h)(1). For example, a scale 
test model of a complete foreign advanced military aircraft described 
in paragraph (a)(2) is described in paragraph (h)(29)(i); however, a 
scale test model of a component of that aircraft is not described in 
paragraph (h)(29)(i). Similarly, a full-scale iron bird rig specially 
designed for a foreign advanced military aircraft described in 
paragraph (a)(2) is described in paragraph (h)(29)(ii); however, a part 
used exclusively in a foreign advanced military aircraft is not 
described in paragraph (h)(1), and a jig specially designed for that 
part is not described in paragraph (h)(29)(iii).

USML Category XI

    Separate from the IFR, the Department assesses the broad 
description of counter-jamming equipment in USML Category XI(a)(4)(iii) 
may impede the Department's intent to improve civil navigation 
resiliency when it removed certain Controlled Reception Pattern 
Antennas (CRPAs) from paragraph (c)(10) in the IFR. To address this, 
the Department is modifying paragraph (a)(4)(iii) to exclude Global 
Navigation Satellite System (GNSS) anti-jam and GNSS anti-spoofing 
systems from that entry. Meanwhile, USML Category XII(d)(3) already 
describes certain GNSS anti-jam systems that continue to provide a 
critical military or intelligence advantage. To improve the clarity of 
paragraph (a)(4)(iii), the Department is also restructuring it by 
splitting its two clauses into subparagraphs (A) and (B), moving the 
parenthetical list of examples into a note, and adding a hyphen to 
``counter-jamming.''
    One commenter additionally noted that, unlike paragraphs (c)(10)(i) 
and (ii) in the IFR, paragraph (c)(10)(iv) does not exclude CRPAs that 
may be used for civil navigation resiliency by identifying the angle of 
arrival of a valid or spoofed GNSS signal. The Department agrees and is 
thus excluding specific CRPAs from this entry and adding a new entry, 
paragraph (c)(10)(vii), to continue to describe CRPAs specially 
designed for functions other than Position, Navigation, and Timing 
(PNT) that meet the technical parameters of the former paragraph 
(c)(10)(iv). Additionally, the Department is relocating the content of 
the note to paragraph (c)(10) into the introductory text of that 
paragraph and is updating it to reference the appropriate versions of 
FAA Traffic Collision Avoidance System (TCAS) and Airborne Collision 
Avoidance System (ACAS) regulations, as the previous references are 
outdated. In response to a separate query, the Department further

[[Page 41781]]

notes that paragraph (c)(10)(iv) was not intended to describe antennas 
developed exclusively for civil airborne weather radar. Views on 
specific examples of why certain antennas developed for this purpose 
may currently be described therein are requested via email to 
[email protected] and may be used to inform future 
rulemakings.
    Another commenter recommended removing USML Category IX(a)(9) 
because radar target generators are also described in USML Category 
XI(a)(3)(xxviii). The Department declines to do so, since USML Category 
XI(a)(3)(xxviii) describes a subset of radar target generators that are 
designated as Significant Military Equipment (SME). That SME 
classification takes precedence in the order of review over the non-SME 
description in USML Category IX(a)(9) of other radar target generators.

USML Category XIII

    The Department is correcting an inadvertent omission of 
[rho]RHA in USML Category XIII(m)(9) as published in the 
IFR, deleting an unnecessary comma in the definition of 
[rho]RHA, restoring the unit designations for Po, 
Pr, and ADTARGET, and adding a unit designation 
for ADRHA. Although the IFR included amendatory instructions 
modifying paragraph (d), upon further examination, the Department finds 
it unnecessary to amend that paragraph or its associated notes at this 
time and is withdrawing the amendatory instructions in the IFR for 
Category XIII(d) via this rule, by not including them in this final 
rule's amendatory instructions.
    The Department is updating paragraph (j)(3)(iv) for consistent 
language, with no change in the scope of control.

USML Category XVIII

    The Department is correcting an administrative oversight in the 
USML where, despite being empty, paragraphs (h) through (w) were not 
marked reserved.

USML Category XX

    To improve its clarity and readability, the Department is amending 
Note 1 to USML Category XX(a)(8) to remove the reference to parts, 
components, accessories, attachments, and associated equipment, noting 
that paragraph (a)(8) does not currently describe any of those 
commodity types. Existing USML Category XX(c) describes those commodity 
types when specially designed for vessels described in paragraph 
(a)(8).
    One commenter stated new paragraphs (a)(9) and (10) describe 
vessels in commercial use, including those used in surveys of subsea 
floors for applications such as drilling, laying subsea cables, and 
marine wind farm installations. The commenter did not identify the 
specific vessels of concern and therefore the Department was unable to 
confirm whether any vessels used for such applications include anti-
recovery features such as scuttle or self-destruct capabilities, which 
the Department assesses provide a critical military or intelligence 
advantage by mitigating the risk of counter-surveillance and 
exploitation of the vessels and serves no compelling commercial 
purpose. The Department also assessed that most of the underwater 
vessels referenced by the commenter are designed to be remotely 
operated and thus do not meet the threshold in paragraph (a)(10) 
concerning operation without human interaction for longer than 24 hours 
or more than 70 nautical miles. The commenter also stated usage of 
these vessels for commercial applications will also be regulated by the 
Department of Commerce's Bureau of Industry and Security (BIS). The 
Department notes this is incorrect, as items described on the USML are 
not subject to BIS's Export Administration Regulations unless 
specifically provided for in the ITAR (e.g., see the note to paragraph 
(d) in USML Category XIX).
    Three other commenters identified vessels, including some models of 
Kongsberg Discovery's HUGIN UUVs, that would be described on the USML 
under the new paragraph (a)(10) and are used in civil applications such 
as oceanographic research or the oil and gas industry. The Department 
has reviewed these vessels and concluded that though some of them are 
or may be used for civil purposes, those described by paragraph (a)(10) 
nevertheless provide a critical military or intelligence advantage and 
thus it declines to remove or update paragraph (a)(10). The weight-
based control concisely and accurately describes the UUVs that provide 
a critical military or intelligence advantage. The size threshold of 
3,000 pounds is based on an estimated technology development trajectory 
and represents the minimum size for a UUV that would enable significant 
weaponization. This considers both integrated weapons as payloads 
(e.g., torpedoes) and non-integrated weapons as cargo (e.g., naval 
mines). The Department's intent is to control large UUVs usable for 
oceanographic research or commercial purposes that could be easily 
used, post-sale, as an effective weapon, or as a weapons delivery or 
Intelligence, Surveillance, and Reconnaissance (ISR) platform. The 24-
hour threshold for operation without human interaction represents the 
typical perishability of information used to task unmanned systems for 
military or intelligence purposes, and it has the effect of excluding 
many civilian remotely operated vehicles. Systems capable of operating 
without human interaction for 24 hours must possess the capability of 
assessing changes in environment, mission context, and self-health and 
adapting to such changes. The alternative threshold of 70 nautical 
miles represents the distance a vessel could travel in 24 hours at an 
average speed of approximately three knots.
    For conciseness and clarity, the Department is also making several 
revisions to the changes to USML Category XX(a) that the IFR made, that 
are set to take effect on September 15, 2025. First, the Department is 
removing the parentheticals ``(and vehicles)'' from paragraphs (a)(9) 
and (10) as unnecessary. References to underwater ``vessels'' in 
Category XX include underwater ``vehicles.'' Second, the Department is 
deleting note 1 to paragraph (a)(10) and relocating the definition of 
``gross weight rating'' into the list of definitions in Sec.  121.0. 
Third, the Department is revising paragraph (b)(2) for greater clarity, 
with no change to the scope of control.

New License Exemption for Certain Large Unmanned Underwater Vehicles 
(UUVs)

    In the IFR, the Department included weight and performance criteria 
in the new USML Category XX(a)(10) paragraph to avoid control of 
systems it assessed are best suited for scientific research or 
commercial applications. In response to the IFR, one commenter proposed 
the Department ensure its regulation of large UUVs only captures 
conduct related to military operations. The Department considered this 
request, along with the technological and economic landscape for these 
vessels and their availability in assessing ways to facilitate U.S. 
participation and collaboration for civilian tasks such as natural 
resource exploration, infrastructure inspection, and oceanographic 
research while continuing to mitigate the risks of their misuse, 
diversion, and proliferation.
    Following research based on this comment, the Department identified 
there are U.S. companies that provide services using such vessels, as 
opposed to selling the vessels. DDTC already

[[Page 41782]]

reviews license applications for contractor-owned contractor-operated 
(COCO) services for Intelligence, Surveillance, and Reconnaissance 
(ISR) and airborne mineral surveys using defense articles and would 
also review COCO licenses for large defense article UUVs.
    Further, in response to feedback from this commenter and the 
commenters described in the section on USML Category XX, and the 
Department's subsequent assessments, the Department is creating a new 
license exemption for a subset of the UUVs described in USML Category 
XX(a)(10) that, although they provide a critical military or 
intelligence advantage such that they warrant description on the USML, 
the Department assesses they are also highly suitable for scientific 
research and specific commercial operations.
    This new exemption will authorize the temporary export, reexport, 
and temporary import of UUVs described in USML Category XX(a)(10) that 
meet the exemption's size restriction of 8,000 pounds, as well as the 
provision of defense services in the maintenance, repair, operation, or 
use of those exempted UUVs, when the controlled activities involve one 
of the exemption's described civil uses. It will also authorize a 
similar scope of brokering activities. However, this exemption will not 
be available if the activities entail the transfer of the vessel's 
registration, control, or ownership to a foreign person.
    While the Department is implementing that license exemption in a 
new Sec.  126.9(u) in this final rule, it still welcomes relevant views 
on this new exemption, including recommended improvements. Comments are 
requested via email to [email protected], and may be used to 
inform future rulemakings.

Effective Date and Updating of Licenses and Agreements

    The Department is implementing an effective date for this rule of 
September 15, 2025, the same implementation date announced in the IFR, 
in making the revisions described in this final rule. One commenter 
requested the Department accelerate the effective date of the rule to 
March 20, 2025. The Department declines to advance or postpone the 
effective date of the rule, having assessed the current effective date 
provides necessary and sufficient time for the regulated community to 
make necessary preparation to implement these changes.

Timeline for Applications, Amendments, and Grandfathering

Items Transitioning Jurisdiction From the ITAR to the EAR

    Items removed from a USML paragraph by this rule may still be 
described in other USML paragraphs or may become subject to the export 
licensing jurisdiction of the Department of Commerce pursuant to the 
EAR. Before determining license requirements, it is important to 
confirm which U.S. Government department or agency has jurisdiction 
over the items that you are planning to transfer, or broker. In 
determining licensing jurisdiction, exporters should evaluate the 
control status of their item using the order of review found at ITAR 
Sec.  120.11 and may submit a commodity jurisdiction request to DDTC 
for assistance, if the licensing jurisdiction or USML classification is 
in doubt. If it is determined that the item is subject to the EAR, 
exporters should evaluate the CCL classification of their item using 
the order of review in supplement no. 4 to part 774 of the EAR and may 
submit a commodity classification request (CCATS) to BIS for 
assistance, if the CCL classification is in doubt. Neither the BIS 
classification nor the CCATS number may be relied upon or cited as 
evidence that the U.S. Government determined that the items described 
in the commodity classification determination are subject to the EAR 
(See 15 CFR 734.3). Licensing requirements under the EAR are determined 
by the reasons for control applicable to the item, the destination, the 
end use, and the end user. General Order No. 5 in supplement no. 1 to 
part 736 of the EAR describes the transition process for items moving 
from the USML to the CCL upon the publication of the pertinent final 
rules. The general order describes the grandfathering of DDTC licenses 
and agreements, the use of BIS authorizations, and the submission of 
disclosures to BIS and DDTC related to the transition of items from the 
USML to the CCL.
    For those wishing to export under the authority of the EAR as soon 
as possible for items moving from the USML to the CCL, applicants may 
submit license applications immediately after the publication of the 
BIS final rule adding such items to the CCL or, in the case of items 
removed from the USML by this final rule, immediately upon its 
publication. Thus, applicants may, in effect, pre-position license 
applications early to facilitate processing of the license application. 
Such a pre-positioned license application will be processed in 
accordance with Sec.  750.4 of the EAR, but if BIS completes processing 
the application prior to the effective date of the applicable final 
rule removing the item from the USML, BIS will hold the application 
without action (HWA), until the effective date of that final rule. 
Applications for transitioned items received after the effective date 
of the final rule removing them from the USML will be processed as 
described in Sec.  750.4 of the EAR.
    Existing holders of DDTC licenses, agreements, or other approvals, 
may maintain existing authorizations or obtain new authorizations for 
items moving from the USML to the CCL.

Acceptance of Licenses

    During the transition period, license applications will be accepted 
by both DDTC and BIS for items moving from the USML to the CCL. BIS 
will not issue approved licenses for such items until on or after the 
effective date of this rule.
    DSP-5 Licenses: Licenses for items transitioning to the CCL that 
are issued prior to the effective date of the final rule and do not 
include items remaining on the USML will remain valid until expired, 
returned by the license holder, or for a period of three years from the 
effective date of the final rule, whichever occurs first, unless 
otherwise revoked, suspended, or terminated. Licenses containing both 
transitioning and non-transitioning items (mixed authorizations) will 
remain valid until expired or returned by the license holder, unless 
otherwise revoked, suspended, or terminated. Any limitation, proviso, 
or other requirement required by the DDTC authorization remains in 
effect if the DDTC authorization is relied upon for export, re-export, 
or re-transfer. License amendment requests received by DDTC prior to 
the effective date of the rule will be adjudicated on a case-by-case 
basis up until the effective date of the rule.
    DSP-61 and DSP-73 Licenses: All temporary licenses that are issued 
in the period prior to the effective date of the rule will remain valid 
until expired or returned by the license holder, unless otherwise 
revoked, suspended, or terminated. Any limitation, proviso, or other 
requirement imposed on the DDTC authorization will remain in effect if 
the DDTC authorization is relied upon for export. License amendment 
requests received by DDTC before the effective date of the rule will be 
adjudicated on a case-by-case basis until the effective date of the 
rule. All license applications, including amendments, received after 
the effective date for items that are transitioning to the CCL that are 
not identified in the application using an (x) paragraph will be

[[Page 41783]]

Without Action (RWA) with instructions to contact the Department of 
Commerce.
    Technical Assistance Agreements, Manufacturing License Agreements, 
Distribution Agreements, and Related Reporting Requirements: Agreements 
and amendments containing both USML and CCL items will be adjudicated 
up to the effective date of the final rule. Agreements containing 
transitioning and non-transitioning items that are issued prior to the 
effective date of the final rule will remain valid until expired, 
unless they require an amendment, or for a period of three years from 
the effective date of the final rule, whichever occurs first, unless 
otherwise revoked, suspended, or terminated. In order for an agreement 
to remain valid beyond three years, an amendment must be submitted to 
authorize the CCL items using the new (x) paragraph from the relevant 
USML category. Any activity conducted under an agreement will remain 
subject to all limitations, provisos, and other requirements stipulated 
in the agreement.
    Agreements containing solely transitioning items issued prior to 
the effective date of the final rule will remain valid for a period of 
three years from the effective date of the rule, unless revoked, 
suspended, or terminated. After the three-year period ends, any ongoing 
activity must be conducted under the appropriate Department of Commerce 
authorization. Agreements and agreement amendments solely for items 
moving to the CCL which are received after the effective date of the 
rule will be Returned Without Action (RWA) with instructions to contact 
the Department of Commerce.
    All reporting requirements for Manufacturing License Agreements and 
Distribution Agreements must be complied with and such reports must be 
submitted to the Department of State while the agreement is relied upon 
as an export authorization by the exporter.

Reexport/Retransfer of USML Items That Have Transitioned to the CCL

    Foreign persons or U.S. persons abroad that have USML items in 
their inventory at the effective date of transition should review both 
the USML and the CCL to determine the proper export jurisdiction of 
those items. If the item is controlled by the Department of Commerce, 
any reexport or retransfer must comply with the requirements of the 
EAR. If doubt exists on the jurisdiction of the items, the foreign 
person should contact the original exporter or manufacturer. In 
instances when those parties are unavailable, the foreign person should 
review the DDTC or BIS website for guidance and support options.
    Following the effective date of this rule, foreign persons 
(including end-users, consignees, and intermediate consignees) who 
receive, via a Department of State authorization, an item they are 
certain has transitioned to the CCL (e.g., confirmed in writing by 
manufacturer or supplier), should treat the item as such and submit 
requests for post-transition reexports or retransfers to the Department 
of Commerce, as may be required by the EAR. If reexport or retransfer 
was previously authorized under an MLA or WDA that continues to provide 
the export authority or any stand-alone reexport/retransfer 
authorization received pursuant to ITAR Sec.  123.9, such 
authorizations remain valid.

Items Transitioning to the USML

    For those wishing to export under the authority of the ITAR as soon 
as possible for items moving onto the USML, applicants may submit 
license applications as soon as this rule is published in the Federal 
Register.

Submission of Voluntary Disclosures or Voluntary Self-Disclosures

    In reviewing the clarifications provided by this rule, if you 
identify a potential violation of the ITAR, you are encouraged to 
submit a voluntary disclosure to DDTC, consistent with the procedures 
outlined in ITAR Sec.  127.12. For potential violations of the EAR, 
persons are encouraged to submit voluntary self-disclosures to BIS, 
consistent with the procedures outlined in EAR Sec. Sec.  764.4 and 
764.5. For potential violations of both the EAR and the ITAR, persons 
are encouraged to submit disclosures to both agencies.

Regulatory Analysis and Notices

Administrative Procedure Act

    This rulemaking is exempt from the rulemaking requirements of 
section 553 of the Administrative Procedure Act (APA) pursuant to 
section 553(a)(1) as a military or foreign affairs function of the 
United States. Although the Department elected to publish an interim 
final rule prior (IFR) to this final rule, it did so without prejudice 
to its determination that controlling the export, reexport, retransfer, 
and temporary import of defense articles and defense services is a 
military or foreign affairs function. Additionally, relying on the same 
APA provision and where noted, the Department is including some changes 
in this final rule that were not presented in the IFR.

Regulatory Flexibility Act

    Since this rule is exempt from the notice-and-comment rulemaking 
provisions of 5 U.S.C. 553, it does not require analysis under the 
Regulatory Flexibility Act.

Unfunded Mandates Reform Act of 1995

    This rulemaking does not involve a mandate that will result in the 
expenditure by state, local, and tribal governments, in the aggregate, 
or by the private sector of $100 million or more in any year and it 
will not significantly or uniquely affect small governments. Therefore, 
no actions are deemed necessary under the provisions of the Unfunded 
Mandates Reform Act of 1995.

Congressional Review Act

    This rule does not meet the criteria of 5 U.S.C. 804(2).

Executive Orders 12372 and 13132

    This rulemaking does not have sufficient federalism implications to 
require consultations or warrant the preparation of a federalism 
summary impact statement. The regulations implementing Executive Order 
12372 regarding intergovernmental consultation on Federal programs and 
activities do not apply to this rulemaking.

Executive Orders 12866 and 13563

    Executive Order 12866, as amended by Executive Order 13563, directs 
agencies to assess all costs and benefits of available regulatory 
alternatives and, if regulation is necessary, to select regulatory 
approaches that maximize net benefits (including potential economic, 
environmental, public health and safety effects, distributed impacts, 
and equity). Executive Order 13563 emphasizes the importance of 
quantifying both costs and benefits, of reducing costs, of harmonizing 
rules, and of promoting flexibility. After review by the Office of 
Management and Budget (OMB), this rule has been deemed to be a 
``significant regulatory action.''
    This rule was undertaken pursuant to a statutory directive to 
periodically review the items on the USML. The Department generally 
determines which items warrant addition to, or removal from, the USML 
by assessing whether each provides a critical military or intelligence 
advantage based on national security and foreign policy considerations. 
Because the costs and benefits of changing what is controlled

[[Page 41784]]

focus on the effect or utility of the item or service, rather than its 
market prevalence or economic value, quantitative analyses cannot be 
usefully estimated and are not available, particularly since the global 
prevalence or availability of the item or service are not known. 
Moreover, the Department does not have useful estimates or models to 
predict whether or how frequently the items added to the USML by this 
rule will be applied for export or to which countries, or for temporary 
import and from which countries. Qualitatively, the rule was assessed 
for costs and benefits. Because listing individual items or model 
numbers would necessarily lead to incomplete controls when an item is 
renamed or slightly modified, the USML contains many descriptive 
controls that are based on broader characteristics, including form, 
fit, function, and performance capability. To more accurately describe 
only what the Department intends to control, and to provide companies 
and individuals with better certainty, some USML revisions made by this 
rule are aimed to improve and clarify various entries and to more 
precisely focus controls. These revisions are also informed by 
confidential commodity jurisdiction determination and advisory opinion 
requests, submitted by industry. The Department takes into account 
common questions and strives to streamline and simplify USML entries 
based on how it understands industry experience with certain parts of 
the USML.
    Finally, when a complete redundancy is identified, as USML Category 
IX(e)(2) was in the IFR, the Department is removing it so that 
exporters, brokers, and temporary importers may better rely on a single 
entry, which can help to reduce compliance costs and increase the 
accuracy of relevant metrics. The alternative to this was inaction or 
delay. The Department could have waited to amend larger parts of the 
USML at once or continued to gather data to evaluate the controls 
affected by this rule. These alternatives were rejected. Statutory 
requirements, including section 38(f) of the Arms Export Control Act 
(22 U.S.C. 2778(f)), and section 1345 of the National Defense 
Authorization Act for Fiscal Year 2024, require a periodic review of 
the USML for edits like those made by this rule. While the Department 
continuously reviews the entire USML, it aims to focus on particular 
USML revisions in cycles, as it has done in implementing this rule.

Executive Order 14192

    This rule is exempt from Executive Order 14192 as it is a 
regulation issued with respect to a foreign affairs or national 
security function of the United States.

Executive Order 12988

    The Department of State has reviewed this rulemaking in light of 
sections 3(a) and 3(b)(2) of Executive Order 12988 to eliminate 
ambiguity, minimize litigation, establish clear legal standards, and 
reduce burden.

Executive Order 13175

    The Department of State has determined that this rulemaking will 
not have tribal implications, will not impose substantial direct 
compliance costs on Indian tribal governments, and will not preempt 
tribal law. Accordingly, the requirements of Executive Order 13175 do 
not apply to this rulemaking.

Paperwork Reduction Act

    This rulemaking does not impose or revise any information 
collections subject to 44 U.S.C. chapter 35.

Signing Authority

    Deputy Secretary Christopher Landau, having reviewed and approved 
this document, has delegated the authority to electronically sign this 
document for purposes of publication in the Federal Register to Senior 
Official Brent T. Christensen, who is performing the duties of the 
Under Secretary for Arms Control and International Security.

    (9) Em is the line-of-sight target mass effectiveness 
ratio and provides a measure of the tested armor's performance to that 
of rolled homogenous armor, where Em is defined as follows:
[GRAPHIC] [TIFF OMITTED] TR27AU25.006

Where:

[rho]RHA = density of MIL-A-12560 RHA (7.85 g/cm\3\)
Po = Baseline Penetration of RHA (mm)
Pr = Residual Line of Sight Penetration, either positive 
or negative (mm RHA equivalent)
ADRHA = Line-of-Sight Areal Density of RHA (kg/
m2)
ADTARGET = Line-of-Sight Areal Density of Target (kg/
m2)

    If witness plate is penetrated, Pr is the distance from 
the projectile to the front edge of the witness plate. If the target 
armor has no measurable penetration, Pr = 0, and the 
Em equation reduces to a ratio of ADRHA/
ADTARGET.
