AGENCY: Enforcement and Compliance, International Trade Administration, Department of Commerce. SUMMARY: The U.S. Department of Commerce (Commerce) determines that countervailable subsidies are being provided to producers and exporters of fiberglass door panels (door panels) from the People's Republic of China (China). The period of investigation is January 1, 2024, through December 31, 2024. DATES: Applicable June 15, 2026. FOR FURTHER INFORMATION CONTACT: Samuel Brummitt or T.J. Worthington, AD/CVD Operations, Office III, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce, 1401 Constitution Avenue NW, Washington, DC 20230; telephone: (202) 482-7851 or (202) 482-4567, respectively. SUPPLEMENTARY INFORMATION: Background On August 21, 2025, Commerce published the Preliminary Determination in the Federal Register and invited interested parties to ( printed page 35964) comment.[1] In accordance with section 705(a)(1) of the Tariff Act of 1930, as amended (the Act), and 19 CFR 351.210(b)(4), Commerce aligned the final countervailing duty (CVD) determination with the final determination in the less-than-fair-value (LTFV) investigation of door panels from China.[2] On March 19, 2026, Commerce issued a post-preliminary analysis.[3] Due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days.[4] Additionally, due to a backlog of documents that were electronically filed via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Access System (ACCESS) during the Federal Government shutdown, on November 24, 2025, Commerce tolled all deadlines in administrative proceedings by an additional 21 days.[5] Accordingly, the deadline for this final determination is now June 8, 2026. For a complete description of the events that followed the Preliminary Determination, see the Issues and Decision Memorandum.[6] The Issues and Decision Memorandum is a public document and is on file electronically via ACCESS. ACCESS is available to registered users at https://access.trade.gov. In addition, a complete version of the Issues and Decision Memorandum can be accessed directly at https://access.trade.gov/frnotices. 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.[7] We received comments from parties on the Preliminary Scope Decision Memorandum, which we address in the Final Scope Decision Memorandum.[8] 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 Act, in December 2025, Commerce conducted a verification of the information reported by Dalian Capstone Engineering Co., Ltd. (Dalian Capstone) [9] and Jiangxi Fangda Tech Co., Ltd. (Jiangxi Fangda).[10] Commerce used standard verification procedures, including an examination of relevant documents provided at verification, in conducting its verification of the company respondents.[11] Analysis of Subsidy Programs and Comments Received The subsidy programs under investigation and the issues raised in the case and rebuttal briefs that were submitted by interested parties in this investigation, are discussed 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. Methodology Commerce conducted this investigation in accordance with section 701 of the Act. For each of the subsidy programs found to be countervailable, Commerce 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.[12] For a full description of the methodology underlying our final determination, see the Issues and Decision Memorandum. In making this final determination, Commerce relied, in part, on facts otherwise available, including with an adverse inference, pursuant to sections 776(a) and (b) of the Act. For a full discussion of our application of adverse facts available (AFA), see the Preliminary Determination,[13] and the Issues and Decision Memorandum at the sections entitled “Use of Facts Otherwise Available and Application of Adverse Inferences.” Changes Since the Preliminary Determination and Post-Preliminary Analysis Based on our analysis of the comments received from interested parties and our verification findings, we made certain changes to the subsidy rate calculations for Dalian Capstone and Jiangxi Fangda. Furthermore, we revised the total AFA rate to: (1) reflect changes to the mandatory respondents' program-specific rates resulting from verification and (2) modify certain program rates selected as part of our application of total AFA to certain non-responsive companies.[14] Lastly, we have revised the rate applicable to all other producers and exporters of subject merchandise in this investigation. For a discussion of these changes, see the Issues and Decision Memorandum. All-Others Rate Pursuant to section 705(c)(5)(A)(i) of the Act, Commerce will determine an all-others rate equal to the weighted-average countervailable subsidy rates established for exporters and/or producers individually examined, excluding any rates that are zero, de ( printed page 35965) minimis, or rates based entirely under section 776 of the Act. In this investigation, Commerce calculated individual estimated countervailable subsidy rates for Dalian Capstone and 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.[15] Final Determination Commerce determines that the following estimated net countervailable subsidy rates exist for the period January 1, 2024, through December 31, 2024: 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). Suspension of Liquidation As a result of our Preliminary Determination, and pursuant to sections 703(d)(l)(B) and (d)(2) of the Act, Commerce instructed U.S. Customs and Border Protection (CBP) to collect cash deposits and suspend liquidation of entries of subject merchandise as described in the scope of the investigation section entered, or withdrawn from warehouse, for consumption on or after August 21, 2025, the date of publication of the Preliminary Determination in the Federal Register .[18] In accordance with section 703(d) of the Act, we instructed CBP to discontinue the suspension of liquidation of all entries of subject merchandise entered or withdrawn from warehouse, on or after December 19, 2025, the first day provisional measures were no longer in effect, but to continue the suspension of liquidation of all entries of subject merchandise on or before December 18, 2025. If the U.S. International Trade Commission (ITC) issues a final affirmative injury determination, we will issue a CVD order, reinstate the suspension of liquidation under section 706(a) of the Act, and require a cash deposit of estimated countervailing duties for such entries of subject merchandise in the amounts indicated above. Pursuant to section 705(c)(2) of the Act, if the ITC determines that material injury, or threat of material injury, does not exist, this proceeding will be terminated, and all estimated duties deposited or securities posted as a result of the suspension of liquidation will be refunded or cancelled. ITC Notification If the ITC determines that material injury or threat of material injury does not exist, this proceeding will be terminated and all cash deposits will be refunded. If the ITC determines that such injury does exist, Commerce will issue a CVD order directing CBP to assess, upon further instruction by Commerce, countervailing duties on all imports of the subject merchandise that are entered, or withdrawn, for consumption on or after the effective date of the suspension of liquidation, as discussed above in the “Continuation of Suspension of Liquidation” section. Administrative Protective Order 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 terms of an ( printed page 35966) APO is a violation which is subject to sanction. Notification to Interested Parties This determination is issued and published pursuant to sections 705(d) and 777(i) of the Act, and 19 CFR 351.210(c). Dated: June 8, 2026. Christopher Abbott, Deputy Assistant Secretary for Policy and Negotiations, performing the non-exclusive functions and duties of the Assistant Secretary for Enforcement and Compliance. 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, 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).
