notice (Issues and Decision Memorandum).
---------------------------------------------------------------------------
Scope of the Investigation
The products covered by this investigation are door panels from
China. For a complete description of the scope of this investigation,
see Appendix I.
Scope Comments
During the course of this investigation, Commerce received scope
comments from parties. Commerce issued a Preliminary Scope Decision
Memorandum to address these comments and set aside a period of time for
parties to address scope issues in scope-specific case and rebuttal
briefs.\4\ We received comments from parties on the Preliminary Scope
Decision Memorandum, which we address in the Final Scope Decision
Memorandum.\5\ We have made no modifications to the scope language as
it appeared in the Preliminary Determination. See Appendix I.

---------------------------------------------------------------------------
Verification
As provided in section 782(i) of the Tariff Act of 1930, as amended
(the Act), in January and March 2026, Commerce verified the sales and
factors of production information submitted by Dalian Capstone
Engineering Co., Ltd. (Capstone) and Jiangxi Fangda Tech Co., Ltd./
Jiangxi Hangda Tech Co., Ltd./Jiangxi Onda Tech Co., Ltd. (Fangda) \6\
for use in our final determination. We used standard verification
procedures, including an examination of relevant sales and accounting
records, and original source documents provided by Capstone and
Fangda.\7\
---------------------------------------------------------------------------
\6\ In the Preliminary Determination, Commerce determined that
Jiangxi Fangda Tech Co., Ltd., Jiangxi Hangda Tech Co., Ltd., and
Jiangxi Onda Tech Co., Ltd. are a single entity, and no party
commented on this finding. Accordingly, we continue to treat these
companies as a single entity for this final determination. See
Preliminary Determination PDM at 9-10.
\7\ See Memoranda, ``Verification of the Questionnaire Responses
of Trinity Glass International, Inc. in the Less-Than-Fair-Value
Investigation of Fiberglass Door Panels from the People's Republic

Analysis of Comments Received
All issues raised in the case and rebuttal briefs submitted by
interested parties in this investigation are addressed in the Issues
and Decision Memorandum. For a list of the issues raised by interested
parties and addressed in the Issues and Decision Memorandum, see
Appendix II to this notice.
Changes Since the Preliminary Determination
Based on Commerce's analysis of the comments received and findings
at verification, we made certain changes since the Preliminary
Determination. Commerce applied partial adverse facts available (AFA)
to a subset of Capstone's U.S. inland freight expenses.\8\ For a
detailed discussion of these changes, see the Issues and Decision
Memorandum.
---------------------------------------------------------------------------
\8\ See Issues and Decision Memorandum at Comment 5.
---------------------------------------------------------------------------
China-Wide Entity and Use of AFA
As discussed in the Preliminary Determination, Commerce assigned an
estimated weighted-average dumping margin to the China-wide entity on
the basis of AFA, pursuant to sections 776(a) and (b) of the Act.\9\ No
party commented on our findings with respect to the China-wide entity
and the use of a dumping margin alleged in the petition as the
appropriate rate assigned to the China-wide entity. Therefore, Commerce
continues to find, pursuant to sections 776(a) and (b) of the Act, that
AFA is warranted in determining the estimated weighted-average dumping
margin for the China-wide entity, and we continue to assign a dumping
margin alleged in the petition (i.e., 147.85 percent) as the applicable
AFA rate, which continues to be corroborated by the transaction-
specific dumping margin calculated for the mandatory respondents.\10\
---------------------------------------------------------------------------
\9\ See Preliminary Determination PDM at 16-17.

for Dalian Capstone Engineering Co. Ltd.,'' dated concurrently with
this memorandum; see also Memorandum, ``Final Analysis Memorandum
for Jiangxi Fangda Tech Co., LTD.,'' concurrently with this
memorandum.
---------------------------------------------------------------------------
Separate Rates
We received no comments on our preliminary separate rate
determinations. We have made no changes with respect to separate rate
eligibility for this final determination.\11\
---------------------------------------------------------------------------
\11\ See Preliminary Determination PDM at 11-14.
---------------------------------------------------------------------------
Combination Rates
Consistent with the Preliminary Determination, Commerce determined
producer/exporter combination rates for companies eligible for a
separate rate.\12\

Disclosure
We intend to disclose the calculations and analysis performed to
interested parties in this final determination within five days of its
public announcement, or if there is no public announcement, within five
days of the date of the publication of this notice in the Federal
Register, in accordance with 19 CFR 351.224(b).
Continuation of Suspension of Liquidation
In accordance with section 735(c)(1)(B) of the Act, we will
instruct U.S. Customs and Border Protection (CBP) to continue to
suspend liquidation of all appropriate entries of subject merchandise,
as described in Appendix I of this notice, which are entered, or
withdrawn from warehouse, for consumption on or after January 22, 2026,
the date of publication of the Preliminary Determination in the Federal
Register.
Pursuant to section 735(c)(1)(B)(ii) of the Act and 19 CFR
351.210(d), Commerce will instruct CBP to require the following cash
deposits of estimated antidumping duties for all appropriate entries:
(1) for the producer/exporter combinations listed in the table above,
the applicable cash deposit rate will be equal to the estimated
weighted-average dumping margin listed in the table for that
combination, adjusted for subsidy offsets, if appropriate; (2) for all
combinations of Chinese producers/exporters of the merchandise under
consideration that have not established eligibility for separate rates,
the cash deposit rate will be equal to the estimated weighted-average
dumping margin established for the China-wide entity, adjusted for
subsidy offsets if appropriate; and (3) for all third-country exporters
of merchandise under consideration not listed in the table above, the
cash deposit rate is the cash deposit rate applicable to the Chinese
producer/exporter combination (or China-wide entity) that supplied that
third-county exporter or, if the producer/exporter combination does not
have its own rate, the cash deposit will be the cash deposit rate for
the China-wide entity. These suspension of liquidation instructions and
cash deposit requirements will remain in effect until further notice.
To determine the cash deposit rate, Commerce normally adjusts the
estimated weighted-average dumping margin by the amount of domestic
pass-through and export subsidies countervailed in a companion
countervailing duty (CVD) proceeding, when CVD provisional measures are
in effect. Accordingly, where Commerce has made a final affirmative
determination for domestic pass-through or export subsidies, Commerce
offsets the estimated weighted-average dumping margin by the
appropriate CVD rate. Commerce has continued to adjust the cash deposit
rate for export subsidies found in the companion CVD investigation by
the appropriate export subsidy rate; however, the suspension of
liquidation of provisional measures in the companion CVD case has been
discontinued.\13\ Therefore, we are not instructing CBP to collect cash
deposits based on the adjusted estimated weighted-average dumping
margin for export subsidies at this time.\14\ If the U.S. International
Trade Commission (ITC) makes a final affirmative determination of
injury due to both dumping and subsidies, then the cash deposit rate
will be revised effective on the date of publication of the ITC's final
affirmative determination in the Federal Register to be the company-
specific estimated weighted-average dumping margin adjusted for export
subsidies.

Alignment of Final Determination with Final Antidumping Duty
Determination, 90 FR 40818. (August 21, 2025); see also section
703(d) of the Act, which states that the provisional measures may
not be in effect for more than four months, which in the companion
CVD case is 120 days after the publication of the preliminary
determination, or December 18, 2025.

ITC Notification
In accordance with section 735(d) of the Act, we will notify the
ITC of our final affirmative determination of sales at LTFV. Because
Commerce's final determination is affirmative, in accordance with
section 735(b)(2) of the Act, the ITC will determine, within 45 days,
whether the domestic industry in the United States is materially
injured, or threatened with material injury, by reason of imports of
door panels from China. If the ITC determines that material injury or
threat of material injury does not exist, the proceeding will be
terminated and all cash deposits will be refunded or canceled, and
suspension of liquidation will be lifted. If the ITC determines that
such injury does exist, Commerce will issue an antidumping duty order
directing CBP to assess, upon further instruction by Commerce,
antidumping duties on all imports of the subject merchandise that are
entered, or withdrawn from warehouse, for consumption on or after the
effective date of the suspension of liquidation, as discussed above in
the section, ``Continuation of Suspension of Liquidation.''
Administrative Protective Order (APO)
This notice will serve as the final reminder to parties subject to
an APO of their responsibility concerning the destruction of
proprietary information disclosed under APO in accordance with 19 CFR
351.305(a)(3). Timely written notification of the return or destruction
of APO materials or conversion to judicial protective order is hereby
requested. Failure to comply with the regulations and the terms of an
APO is a violation which is subject to sanction.
Notification to Interested Parties
This determination and notice are issued and published pursuant to
sections 735(d) and 777(i)(1) of the Act, and 19 CFR 351.210(c).

Appendix I
Scope of the Investigation
The merchandise covered by this investigation consists of
fiberglass door panels, including fiberglass sidelites, whether
finished or unfinished, whether assembled or unassembled, whether
pre-
[[Page 35963]]
hung or included in an entry door system. The subject fiberglass
door panels consist of at least one fiberglass skin, and may contain
(1) frames typically made of wood or composite stiles, bottom rails,
and top rails, (2) binding materials, including adhesives or
fasteners, and (3) insulation foam or other insulating material, and
may be assembled with glass lites (glass that is ultimately
installed in the fiberglass door panel). Fiberglass sidelites (or
``sidelights'') are typically smaller in width than fiberglass door
panels, and consist of at least one fiberglass skin, and may contain
(1) frames typically made of wood or composite stiles, bottom rails,
and top rails, (2) binding materials, including adhesives or
fasteners, and (3) insulation foam or other insulating material, and
may be assembled with glass lites (glass that is ultimately
installed in the fiberglass sidelite). Subject merchandise includes
fiberglass door panels and sidelites whether the fiberglass skin
surface is painted or unpainted, contains or does not contain cut-
outs for door components, or assembled or unassembled with glass
lites in the door.
The country of origin of the fiberglass door panel is determined
by where the fiberglass door skin is pressed.
Fiberglass door panels and sidelites are covered by the
investigation whether they are imported attached to, or in
conjunction with door components and accessories (including but not
limited to door jambs, door handles, locks, hinges, door stoppers,
door kicks, door thresholds, door sills, and trim), in a pre-hung
door system, or an entry door system. Subject fiberglass door panels
and sidelites are covered whether or not they are accompanied by
other parts. However, if a subject fiberglass door panel or sidelite
is imported in a pre-hung door system or entry door system, only the
fiberglass door panel and sidelite, including when assembled with
glass lites or when the glass lites are shipped with the subject
merchandise for further assembly, are covered by the scope. Door
components and accessories (including but not limited to transoms,
door jambs, door handles, locks, hinges, door stoppers, door kicks,
door thresholds, door sills, and trim) are not included in the scope
when imported with a fiberglass door panel or sidelite, including
when such components or accessories are assembled to a fiberglass
door panel or sidelite, or when imported separately. Subject
merchandise may be impact-rated to withstand hurricane force wind
loads and may be reinforced with steel sheet or plate. Impact-rated
doors may be certified to Testing Application Standards (TAS) 201/
202/203-94/and American Society for Testing and Materials (ASTM)
E330-02/14/M-14, E1886-05/13a/, or E1996-09/14a.
Subject merchandise may be fire-rated for up to 90 minutes and
may contain flame retardant composites, including, but not limited
to flame retardant foam or mineral core materials, including but not
limited to low density calcium silicate. Fire-rated doors generally
satisfy the National Fire Protection Association (NFPA) 252 Standard
Methods of Fire Tests of Door Assemblies and UL10(b) and (c)-
Standard for Safety-Fire Tests of Door Assemblies.
Subject merchandise also includes fiberglass door panels and
sidelites that have been processed in a third country, including but
not limited to one or more of the following: filling with insulation
foam, trimming, cutting, notching, punching, drilling, painting,
finishing, assembly, or any other processing that would not
otherwise remove the merchandise from the scope of the investigation
if performed in the country of manufacture of the in-scope product.
The inclusion of other parts, such as door components and
accessories (including but not limited to door jambs, door handles,
locks, hinges, door stoppers, door kicks, door thresholds, door
sills, and trim) in a third country does not remove the fiberglass
door panels and sidelites from the scope.
Excluded from the scope of this investigation are all products
covered by the scope of the antidumping duty and countervailing duty
orders on wood mouldings and millwork products from China. See Wood
Mouldings and Millwork Products from the People's Republic of China:
Amended Final Antidumping Duty Determination and Antidumping Duty
Order, 86 FR 9486 (February 16, 2021); and Wood Mouldings and
Millwork Products from the People's Republic of China:
Countervailing Duty Order, 86 FR 9484 (February 16, 2021).
Excluded from the scope of this investigation are all products
covered by the scope of the antidumping duty and countervailing duty
proceedings on float glass products from China. See Float Glass
Products from the People's Republic of China and Malaysia:
Initiation of Less-Than-Fair-Value Investigations, 90 FR 1435
(January 8, 2025); and Float Glass Products from the People's
Republic of China and Malaysia: Initiation of Countervailing Duty
Investigations, 90 FR 1443 (January 8, 2025).
Imports of subject merchandise are classified under Harmonized
Tariff Schedule of the United States (HTSUS) statistical number
3925.20.0010. Subject merchandise may also be classified under
4418.29.4000, 4418.29.8030, 4418.29.8060, or 7019.90.5150. The HTSUS
subheadings are provided for convenience and customs purposes; the
written description of the scope of this investigation is
