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

Methodology

    Commerce is conducting this investigation in accordance with 
section 731 of the Act. Constructed export prices have been calculated 
in accordance with section 772(b) of the Act. Normal value is 
calculated in accordance with section 773 of the Act. Furthermore, 
pursuant to sections 776(a) and (b) of the Act, Commerce preliminarily 
relied upon facts otherwise available, with adverse inferences for 
Panus Assembly Co., Ltd. (Panus). For a full description of the 
methodology underlying the preliminary determination, see the 
Preliminary Decision Memorandum.

All-Others Rate

    Sections 733(d)(1)(ii) and 735(c)(5)(A) of the Act provide that in 
the preliminary determination Commerce shall determine an estimated 
all-others rate for all exporters and producers not individually 
examined. This rate shall be an amount equal to the weighted average of 
the estimated weighted-average dumping margins established for 
exporters and producers individually investigated, excluding any zero 
and de minimis margins, and any margins determined entirely under 
section 776 of the Act.
    Commerce calculated an individual estimated weighted-average 
dumping margin for Dee Siam Manufacturing Co., Ltd. (Dee Siam), the 
only individually examined exporter and producer for which a rate was 
calculated in this investigation. Because the only individually 
calculated dumping margin is not zero, de minimis, or based entirely on 
facts otherwise available, the estimated weighted-average dumping 
margin calculated for Dee Siam is the margin assigned to all other 
producers

[[Page 46551]]

and exporters, pursuant to section 735(c)(5)(A) of the Act.

Preliminary Determination

    Commerce preliminarily determines that the following estimated 
weighted-average dumping margins exist:

------------------------------------------------------------------------
                                     Estimated        Cash deposit rate
                                  weighted-average      (adjusted for
       Exporter/producer           dumping margin    subsidy offset(s))
                                     (percent)            (percent)
------------------------------------------------------------------------
Dee Siam Manufacturing Co., Ltd              46.12                 46.12
Panus Assembly Co., Ltd........           * 181.57              * 181.57
All Others.....................              46.12                 46.12
------------------------------------------------------------------------
* This rate is based on facts available with adverse inferences.

Suspension of Liquidation and Cash Deposit Requirements

    In accordance with section 733(d)(2) of the Act, Commerce will 
direct U.S. Customs and Border Protection (CBP) to suspend liquidation 
of entries of subject merchandise, as described in Appendix I, entered, 
or withdrawn from warehouse, for consumption on or after the date of 
publication of this notice in the Federal Register. Further, pursuant 
to section 733(d)(1)(B) of the Act and 19 CFR 351.205(d), Commerce will 
instruct CBP to require a cash deposit equal to the estimated weighted-
average dumping margin or the estimated all-others rate, as follows: 
(1) the cash deposit rate for the respondents listed above will be 
equal to the company-specific estimated weighted-average dumping 
margins determined in this preliminary determination; (2) if the 
exporter is not a respondent identified above, but the producer is, 
then the cash deposit rate will be equal to the company-specific 
estimated weighted-average dumping margin established for that producer 
of the subject merchandise and (3) the cash deposit rate for all other 
producers and exporters will be equal to the all-others estimated 
weighted-average dumping margin.
    Commerce normally adjusts cash deposits for estimated antidumping 
duties by the amount of export subsidies countervailed in a companion 
countervailing duty (CVD) proceeding, when CVD provisional measures are 
in effect. Accordingly, where Commerce preliminarily made an 
affirmative determination for countervailable export subsidies, 
Commerce has offset the estimated weighted-average dumping margin by 
the appropriate CVD rate. For this preliminary determination, Commerce 
did not adjust the estimated weighted-average dumping margins. As an 
extension of adverse inference, pursuant to section 776(b) of the Act, 
Commerce adjusted Panus's cash deposit rate by the lowest export 
subsidy rate determined in the CVD investigation, which is zero 
percent.\7\ Commerce did not adjust Dee Siam's or the all-other's 
estimated dumping margin because Commerce preliminarily determined that 
Dee Siam did not benefit from subsidy programs contingent on 
exports.\8\
---------------------------------------------------------------------------

    \7\ See Preliminary Decision Memorandum at 29.
    \8\ Id.
---------------------------------------------------------------------------

    These suspension of liquidation instructions will remain in effect 
until further notice.

Disclosure

    Commerce intends to disclose its calculations and analysis 
performed to interested parties in this preliminary determination 
within five days of any public announcement or, if there is no public 
announcement, within five days of the date of publication of this 
notice in accordance with 19 CFR 351.224(b).
    Consistent with 19 CFR 351.224(e), Commerce will analyze and, if 
appropriate, correct any timely allegations of significant ministerial 
errors by amending the preliminary determination. However, consistent 
with 19 CFR 351.224(d), Commerce will not consider incomplete 
allegations that do not address the significance standard under 19 CFR 
351.224(g) following the preliminary determination. Instead, Commerce 
will address such allegations in the final determination together with 
issues raised in the case briefs or other written comments.

Verification

    As provided in section 782(i)(1) of the Act, Commerce intends to 
verify the information relied upon in making its final determination 
with respect to Dee Siam. However, because Panus is receiving a rate 
based on facts available with adverse inferences, and Commerce 
preliminarily determines Panus has been uncooperative, we do not intend 
to conduct verification of Panus' information.

Public Comment

    Case briefs or other written comments may be submitted to the 
Assistant Secretary for Enforcement and Compliance no later than seven 
days after the date on which the last verification report is issued in 
this investigation. Rebuttal briefs, limited to issues raised in the 
case briefs, may be filed not later than five days after the date for 
filing case briefs.\9\ Interested parties who submit case briefs or 
rebuttal briefs in this proceeding must submit: (1) a table of contents 
listing each issue; and (2) a table of authorities.\10\

Order, Service, and Other Procedures in Antidumping and 
Countervailing Duty Proceedings, 88 FR 67069, 67077 (September 29, 
2023) (APO and Service Final Rule).
    \10\ See 19 351.309(c)(2) and (d)(2).
---------------------------------------------------------------------------

    As provided under 19 CFR 351.309(c)(2) and (d)(2), in prior 
proceedings we have encouraged interested parties to provide an 
executive summary of their brief that should be limited to five pages 
total, including footnotes. In this investigation, we instead request 
that interested parties provide at the beginning of their briefs a 
public, executive summary for each issue raised in their briefs.\11\ 
Further, we request that interested parties limit their executive 
summary of each issue to no more than 450 words, not including 
citations. We intend to use the executive summaries as the basis of the 
comment summaries included in the issues and decision memorandum that 
will accompany the final determination in this investigation. We 
request that interested parties include footnotes for relevant 
citations in the executive summary of each issue. Note that Commerce 
has amended certain of its requirements pertaining to

the service of documents in 19 CFR 351.303(f).\12\
---------------------------------------------------------------------------

    \11\ We use the term ``issue'' here to describe an argument that 
Commerce would normally address in a comment of the Issues and 
Decision Memorandum.
    \12\ See APO and Service Final Rule.
---------------------------------------------------------------------------

    Pursuant to 19 CFR 351.310(c), interested parties who wish to 
request a hearing, limited to issues raised in the case and rebuttal 
briefs, must submit a written request to the Assistant Secretary for 
Enforcement and Compliance, U.S. Department of Commerce, within 30 days 
after the date of publication of this notice. Requests should contain 
the party's name, address, and telephone number, the number of 
participants, whether any participant is a foreign national, and a list 
of the issues to be discussed. If a request for a hearing is made, 
Commerce intends to hold the hearing at a time and date to be 
determined. Parties should confirm by telephone the date, time, and 
location of the hearing two days before the scheduled date.

Postponement of Final Determination and Extension of Provisional 
Measures

    Section 735(a)(2) of the Act provides that a final determination 
may be postponed until not later than 135 days after the date of the 
publication of the preliminary determination if, in the event of an 
affirmative preliminary determination, a request for such postponement 
is made by exporters who account for a significant proportion of 
exports of the subject merchandise, or in the event of a negative 
preliminary determination, a request for such postponement is made by 
the petitioner. Pursuant to 19 CFR 351.210(e)(2), Commerce requires 
that a request by exporters for postponement of the final determination 
be accompanied by a request for extension of provisional measures from 
a four-month period to a period not more than six months in duration.
    On September 17, 2025, Panus requested postponement of the final 
determination.\13\ On September 18, 2025, pursuant to 19 CFR 
351.210(e), the petitioner and Dee Siam requested that Commerce 
postpone the final determination and that provisional measures be 
extended to a period not to exceed six months.\14\ In accordance with 
section 735(a)(2)(A) of the Act and 19 CFR 351.210(b)(2)(ii), because: 
(1) the preliminary determination is affirmative; (2) the requesting 
exporters account for a significant proportion of exports of the 
subject merchandise; and (3) no compelling reasons for denial exist, 
Commerce is postponing the final determination and extending the 
provisional measures from a four-month period to a period not greater 
than six months. Accordingly, Commerce will make its final 
determination no later than 135 days after the date of publication of 
this preliminary determination.

U.S. International Trade Commission (ITC) Notification

    In accordance with section 733(f) of the Act, Commerce will notify 
the ITC of its preliminary determination. If the final determination is 
affirmative, the ITC will determine before the later of 120 days after 
the date of this preliminary determination or 45 days after the final 
determination whether these imports are materially injuring, or 
threaten material injury to, the U.S. industry.

Appendix I

Scope of the Investigation

    The merchandise covered by these investigations consists of 
chassis and subassemblies thereof whether finished or unfinished, 
whether assembled or unassembled, whether coated or uncoated, 
regardless of the number of axles, for carriage of containers, or 
other payloads (including self-supporting payloads) for road, marine 
roll-on/roll-off (RORO) and/or rail transport. Chassis are 
typically, but are not limited to, rectangular framed trailers with 
a suspension and axle system, wheels and tires, brakes, a lighting 
and electrical system, a coupling for towing behind a truck tractor, 
and a locking system or systems to secure the shipping container or 
containers to the chassis using twistlocks, slide pins or similar 
attachment devices to engage the corner fittings on the container or 
other payload.
    Subject merchandise includes, but is not limited to, the 
following subassemblies:
    <bullet> Chassis frames, or sections of chassis frames, 
including kingpin assemblies, bolsters consisting of transverse 
beams with locking or support mechanisms, goosenecks, drop 
assemblies, extension mechanisms and/or rear impact guards;
    <bullet> Running gear assemblies or axle assemblies for 
connection to the chassis frame, whether fixed in nature or capable 
of sliding fore and aft or lifting up and lowering down, which may 
or may not include suspension(s) (mechanical or pneumatic), wheel 
end components, slack adjusters, dressed axles, brake chambers, 
locking pins, and tires and wheels; and
    <bullet> Assemblies that connect to the chassis frame or a 
section of the chassis frame, such as but not limited to, pintle 
hooks or B-trains (which include a fifth wheel), which are capable 
of connecting a chassis to a converter dolly or another chassis.
    Importation of any of these subassemblies, whether assembled or 
unassembled, constitutes an unfinished chassis for purposes of these 
investigations.
    Subject merchandise also includes chassis, whether finished or 
unfinished, entered with components such as, but not limited to: hub 
and drum assemblies, brake assemblies (either drum or disc), bare 
axles, brake chambers, suspensions and suspension components, wheel 
end components, landing gear legs, spoke or disc wheels, tires, 
brake control systems, electrical harnesses and lighting systems.
    Processing of finished and unfinished chassis and components 
such as trimming, cutting, grinding, notching, punching, drilling, 
painting, coating, staining, finishing, assembly, or any other 
processing either in the country of manufacture of the in-scope 
product or in a third country does not remove the product from the 
scope. Inclusion of other components not identified as comprising 
the finished or unfinished chassis does not remove the product from 
the scope.
    Individual components entered and sold by themselves are not 
subject to the investigations, but components entered with a 
finished or unfinished chassis are subject merchandise. A finished 
chassis is ultimately comprised of several different types of 
subassemblies. Within each subassembly there are numerous components 
that comprise a given subassembly.
    This scope excludes dry van trailers, refrigerated van trailers 
and flatbed trailers. Dry van trailers are trailers with a wholly 
enclosed cargo space comprised of fixed sides, nose, floor and roof, 
with articulated panels (doors) across the rear and occasionally at 
selected places on the sides, with the cargo space being permanently 
incorporated in the trailer itself. Refrigerated van trailers are 
trailers with a wholly enclosed cargo space comprised of fixed 
sides, nose, floor and roof, with articulated panels (doors) across 
the rear and occasionally at selected places on the sides, with the 
cargo space being permanently incorporated in the trailer and being 
insulated, possessing specific thermal properties intended for use 
with self-contained refrigeration systems. Flatbed (or platform) 
trailers consist of load carrying main frames and a solid, flat or 
stepped loading deck or floor permanently incorporated with and 
supported by frame rails and cross members.
    The finished and unfinished chassis subject to these 
investigations are typically classified in the Harmonized Tariff 
Schedule of the United States (HTSUS) at subheadings: 8716.39.0090 
and 8716.90.5060. Imports of finished and unfinished chassis may 
also enter under HTSUS subheading 8716.90.5010. While the HTSUS 
subheadings are provided for convenience and customs

[[Page 46553]]

purposes, the written description of the merchandise under 
investigation is dispositive.
