**SUPPLEMENTARY INFORMATION:**
**Background**
This preliminary determination is made in accordance with section 703(b) of the Tariff Act of 1930, as amended (the Act). Commerce published the notice of initiation of this investigation on April 15, 2025. [^1] On May 29, 2025, Commerce postponed the preliminary determination of this investigation and the revised deadline is now August 18, 2025. [^2] For a complete description of the events that followed the initiation of this investigation, *see* the Preliminary Decision Memorandum. [^3] A list of topics discussed in the Preliminary Decision Memorandum is included as Appendix II to this notice. The Preliminary Decision Memorandum is a public document and is on file electronically via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS). ACCESS is available to registered users at *https://access.trade.gov* . In addition, a complete version of the Preliminary Decision Memorandum can be accessed directly at *https://access.trade.gov/public/FRNoticesListLayout.aspx* .

**Scope of the Investigation**
The product covered by this investigation is fiberglass door panels from China. For a complete description of the scope of this investigation, *see* Appendix I.
**Scope Comments**
In accordance with the *Preamble* to Commerce's regulations, [^4] the *Initiation Notice* set aside a period of time for parties to raise issues regarding product coverage, ( *i.e.,* scope). [^5] Certain interested parties commented on the scope of the investigation as it appeared in the *Initiation Notice* . Commerce intends to issue its preliminary decision regarding comments concerning the scope of the less-than-fair-value (LTFV) and countervailing duty (CVD) investigations in the preliminary determination of the companion LTFV investigation. We will incorporate the scope decision from the LTFV investigation into the scope of the final CVD determination for this investigation after considering any relevant comments submitted in scope case and rebuttal briefs. [^6]

[^6] The deadline for interested parties to submit scope case and rebuttal briefs will be established in the preliminary scope decision memorandum accompanying preliminary determination of the LTFV investigation.
**Methodology**
Commerce is conducting this investigation in accordance with section 701 of the Act. For each of the subsidy programs found countervailable, Commerce preliminarily determines that there is a subsidy, *i.e.,* a financial contribution by an “authority” that gives rise to a benefit to the recipient, and that the subsidy is specific. [^7] For a full description of the methodology underlying our preliminary determination, *see* the Preliminary Decision Memorandum.
[^7]*See* sections 771(5)(B) and (D) of the Act regarding financial contribution; section 771(5)(E) of the Act regarding benefit; and section 771(5A) of the Act regarding specificity.
Commerce notes that, in making these findings, it relied, in part, on facts available and, because it finds that certain respondents did not act to the best of their ability to respond to Commerce's requests for information, it drew an adverse inference, where appropriate, in selecting from among the facts otherwise available. [^8] For further information, *see* the “Use of Facts Otherwise Available and Adverse Inferences” section in the Preliminary Decision Memorandum.
[^8]*See* sections 776(a) and (b) of the Act.
**Alignment**
As noted in the Preliminary Decision Memorandum, in accordance with section 705(a)(1) of the Act and 19 CFR 351.210(b)(4), Commerce is aligning the final CVD determination in this investigation with the final determination in the companion LTFV investigation of fiberglass door panels from China based on a request made by the petitioner. [^9] Consequently, the final CVD determination will be issued on the same date as the final LTFV determination, which is currently scheduled to be issued no later than December 30, 2025, unless postponed.
[^9]*See* Petitioner's Letter, “Request to Align Countervailing Duty Investigation Final Determination with Antidumping Duty Investigation Final Determination,” dated August 13, 2025.
**All-Others Rate**
Sections 703(d) and 705(c)(5)(A) of the Act provide that in the preliminary determination, Commerce shall determine an estimated all-others rate for companies not individually examined. This rate shall be an amount equal to the weighted average of the estimated subsidy rates established for those companies individually examined, excluding any zero and *de minimis* rates and any rates based entirely under section 776 of the Act. Pursuant to section 705(c)(5)(A)(ii) of the Act, if the individual estimated countervailable subsidy rates established for all exporters and producers individually examined are zero, *de minimis,* or determined based entirely on facts otherwise available, Commerce may use any reasonable method to establish the estimated subsidy rate for all other producers or exporters. In this investigation, Commerce calculated individual estimated countervailable subsidy rates for Dalian Capstone Engineering Co., Ltd. (Dalian Capstone) and Jiangxi Fangda Tech Co., Ltd. (Jiangxi Fangda) that are not zero, *de minimis,* or based entirely on facts otherwise available. Commerce calculated the all-others rate using a weighted average of the individual estimated subsidy rates calculated for the examined respondents using each company's publicly-ranged values for the merchandise under consideration. [^10]
[^10] With two respondents under examination, Commerce normally calculates: (A) a weighted-average of the estimated subsidy rates calculated for the examined respondents; (B) a simple average of the estimated subsidy rates calculated for the examined respondents; and (C) a weighted-average of the estimated subsidy rates calculated for the examined respondents using each company's publicly-ranged U.S. sale values for the merchandise under consideration. Commerce then compares (B) and (C) to (A) and selects the rate closest to (A) as the most appropriate rate for all other producers and exporters. *See, e.g., Ball Bearings and Parts Thereof from France, Germany, Italy, Japan, and the United Kingdom: Final Results of Antidumping Duty Administrative Reviews, Final Results of Changed-Circumstances Review, and Revocation of an Order in Part,* 75 FR 53661, 53662 (September 1, 2010), and accompanying Issues and Decision Memorandum at Comment 1. As complete, publicly-ranged sales data were available, Commerce based the all-others rate on the publicly-ranged sales data of the mandatory respondents. For a complete analysis of the data, *see* the All-Others Rate Calculation Memorandum.
**Rate for Non-Responsive Companies**
Six exporters and/or producers of fiberglass door panels from China failed to provide responses to Commerce's quantity and value questionnaire. We find that, by not responding to Commerce's requests for information, each of these companies withheld requested information and significantly impeded this proceeding. Thus, in reaching our preliminary determination, pursuant to sections 776(a)(2)(A) and (C) of the Act, we are basing the subsidy rate for the non-responsive companies on facts otherwise available. [^11]
[^11] These companies are: (1) Kits Glass (China) Limited; (2) Hebei Charlotte Enterprise Co., Ltd.; (3) Lily Industries Co., Ltd.; (4) Shanghai Unikey International Trading Co., Ltd.; (5) Zhejiang Kuchuan Door Co., Ltd; and (6) Zhenshi Group Huamei New Materials Co Ltd.
We further preliminarily determine that an adverse inference is warranted, pursuant to section 776(b) of the Act. By failing to submit responses to Commerce's questionnaires, the non-responsive companies did not cooperate to the best of their ability in this investigation. Accordingly, we preliminarily find that an adverse inference is warranted to ensure that the non-responsive companies will not obtain a more favorable result than had they fully complied with our requests for information. For more information on the application of adverse facts available to the non-responsive companies, *see* the “Use of Facts Otherwise Available and Adverse Inferences” section in the Preliminary Determination Memorandum.
**Preliminary Determination**
Commerce preliminarily determines that the following estimated countervailable subsidy rates exist:
[^12] As discussed in the Preliminary Decision Memorandum, Commerce has found the following company to be cross-owned with Dalian Capstone: Qinhuangdao Entrylite Co., Ltd.
[^13] As discussed in the Preliminary Decision Memorandum, Commerce has found the following companies to be cross-owned with Jiangxi Fangda: Jiangxi Hangda Tech Co., Ltd.; Jiangxi Onda Tech Co., Ltd.; and one affiliate whose name is business proprietary. *See* the Jiangxi Fangda proprietary preliminary calculation memorandum.
| Company | Subsidy rate |
| --- | --- |
| Dalian Capstone Engineering Co., Ltd. | 71.37 |
| Jiangxi Fangda Tech Co., Ltd. | 59.17 |
| Kits Glass (China) Limited | * 921.42 |
| Hebei Charlotte Enterprise Co., Ltd | * 921.42 |
| Lily Industries Co., Ltd | * 921.42 |
| Shanghai Unikey International Trading Co., Ltd | * 921.42 |
| Zhejiang Kuchuan Door Co., Ltd | * 921.42 |
| Zhenshi Group Huamei New Materials Co Ltd | * 921.42 |
| All Others | 62.55 |
**Suspension of Liquidation**
In accordance with section 703(d)(1)(B) and (d)(2) of the Act, Commerce will direct U.S. Customs and Border Protection (CBP) to suspend liquidation of entries of fiberglass door panels, as described in the scope of the investigation section, entered, or withdrawn from warehouse, for consumption on or after the date of publication of this notice in the *Federal Register* . Further, pursuant to 19 CFR 351.205(d), Commerce will instruct CBP to require a cash deposit equal to the rates indicated above.
**Disclosure**
Commerce intends to disclose its calculations and analysis performed to interested parties in this preliminary determination within five days of its public announcement, or if there is no public announcement, within five days of the date 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.
**Public Comment**
All interested parties will have the opportunity to submit scope case and rebuttal briefs on the preliminary decision regarding the scope of the LTFV and CVD investigations. The deadlines to submit scope case and rebuttal briefs will be provided in the preliminary scope decision memorandum accompanying the preliminary determination of the LTFV investigation. For all scope case and rebuttal briefs, parties must file identical documents simultaneously on the records of the ongoing LTFV and CVD investigations. No new factual information or business proprietary information may be included in either scope case or rebuttal briefs.
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.

**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-hung or included in an entry door system. The subject fiberglass door panels consist of at least one fiberglass skin, frames typically made of wood or composite stiles, bottom rails, and top rails, binding materials, including adhesives or fasteners, insulation foam, 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, frames typically made of wood or composite stiles, bottom rails, and top rails, binding materials, including adhesives or fasteners, insulation foam, 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.
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 the People's Republic of 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.
