China Fiberglass Door Panels: New AD/CVD Investigations Deadlines & Scope

The International Trade Commission will conduct a concurrent investigation to determine whether imports of dumped and illegally subsidized fiberglass door panels are injuring U.S. industry. If the ITC finds no injury in its preliminary injury determination, due May 5, the investigations will immediately end. If Commerce finds dumping or illegal subsidization in the preliminary determinations of these investigations, due in June for CVD and in August for AD, it will set AD and/or CVD cash deposit requirements for imports of merchandise subject to the investigation. If both Commerce and the ITC reach affirmative final determinations, Commerce will issue an AD and/or CVD order making duties permanent and beginning a process of annual administrative reviews to set final assessments of AD/CVD on importers and potentially set new AD/CVD cash deposit rates.

AD/CVD Respondent Selection

For its CVD investigation, Commerce said it will select respondents for individual examination based on CBP import data. For its AD investigation, Commerce said it will pick respondents for individual examination by issuing quantity and value questionnaires to the largest producers and/or exporters that are identified in CBP POI entry data and have complete address information on the record.

Exporters that don't get a quantity and value questionnaire can submit one using the forms available on Commerce's website. Responses are due April 23 at 5 p.m. EDT.

Companies subject to the AD investigations on China will also have to submit a separate rate application to avoid getting the high China-wide rate. Separate rate applications will be due 21 days from the publication date of Commerce's AD initiation notice.

Scope of the AD/CVD Investigations

"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 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.
