Wiley Files Petitions for U.S. Fiberglass Door Panel Manufacturers to Level the Playing Field in Response to Harmful Chinese Trade Practices

March 24, 2025

Washington, DC - Wiley has filed antidumping and countervailing duty (AD/CVD) petitions on behalf of the American Fiberglass Door Coalition with the U.S. Department of Commerce and the U.S. International Trade Commission (USITC) seeking to address unfair dumping practices and subsidy programs by the People’s Republic of China (PRC).

The petition alleges dumping by Chinese fiberglass door panel producers, and also alleges that the PRC government is subsidizing more than 65 different programs benefiting the Chinese industry, including provisions of 29 products at subsidized rates, 10 grant programs, 17 tax programs, and 10 lending programs. As a result, the petition urges the Commerce Department to initiate investigations into PRC’s potentially illegal trade practices and return the fiberglass door panel industry to a level playing field.

The filing, made concurrently with the U.S. Department of Commerce and the U.S. International Trade Commission, is in response to the surge in volumes of unfairly traded Chinese imports.

“We hope that the Commerce Department and the International Trade Commission will take action to remedy these unfair and illegal trading practices by the PRC,” said Timothy C. Brightbill, trade counsel to the Coalition and co-chair of Wiley’s International Trade Practice. “This widespread subsidization and dumping of fiberglass door products is harmful to U.S. industry, and it is critical that the U.S. government thoroughly investigates to provide relief to domestic manufacturers through fair competition among producers.”

FACT SHEET

Antidumping and Countervailing Duties: Antidumping duties are intended to offset the amount by which a product is sold at less than fair value, or “dumped,” in the United States. The margin of dumping is calculated by Commerce. Estimated duties in the amount of the dumping are collected from importers at the time of importation. Countervailing duties are intended to offset unfair subsidies that are provided by foreign governments and benefit the production of a particular good. The USITC, an independent agency, will determine whether the domestic industry is materially injured or threatened with material injury by reason of the unfairly traded imports

Product Description: The products covered by this investigation consist 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, including fiberglass sidelites, 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.

Next Steps: Commerce will determine whether to initiate the investigations within 20 days of filing, and the USITC will reach a preliminary determination of material injury or threat of material injury within 45 days. The entire investigative process will take approximately one year, with final determinations of dumping, subsidization, and injury likely occurring in early 2026. However, duties can be attached to imports of the subject fiberglass door panels at the time of the preliminary determinations in the case, or even earlier.

The Wiley team representing the Coalition also includes International Trade partners Robert E. DeFrancesco, III and Derick G. Holt, and associate Kimberly A. Reynolds.
