US Slaps Tariffs on Cheap Chinese Fiberglass Door Panels
Published Date: 8/6/2026
Notice
Summary
Starting August 6, 2026, the U.S. is putting special taxes on fiberglass door panels from China because they're being sold unfairly cheap and getting unfair government help. This move protects American door makers from losing business and helps keep the market fair. If you import or sell these door panels, expect new costs and rules to follow.

Antidumping Duties Imposed on China Door Panels
Commerce issued an antidumping (AD) order on fiberglass door panels from China and will require cash deposits equal to the estimated weighted-average dumping margins. The listed margins include Anhui Xinyu 73.07% (cash deposit 72.94%), Wuxi Lutong 73.07% (72.94%), Dalian Capstone 41.82% (41.79%), Jiangxi Fangda 104.31% (104.08%), and a China-wide rate of 147.85% (147.82%). Antidumping duties will be assessed on unliquidated entries entered, or withdrawn from warehouse for consumption, on or after January 22, 2026, and suspension of liquidation and cash deposit requirements were reinstated effective on the publication of the ITC final injury determination in the Federal Register (August 6, 2026).
Countervailing Duties (Subsidy) Rates Set
Commerce issued a countervailing duty (CVD) order and listed estimated subsidy rates for specific Chinese producers of fiberglass door panels. Listed rates include Dalian Capstone 66.22%, Jiangxi Fangda 58.50%, several companies at 186.46% (based on adverse facts available), and an "All Others" rate of 60.64%. Countervailing duties will be assessed on relevant entries entered, or withdrawn from warehouse for consumption, on or after August 21, 2025, subject to the provisional-measures exceptions described in the notice, and suspension of liquidation and cash deposit requirements were reinstated upon publication of the ITC final injury determination (August 6, 2026).
Which Products Are Covered by the Orders
The orders cover fiberglass door panels and fiberglass sidelites from China, whether finished or unfinished, assembled or unassembled, pre-hung or in an entry door system, and whether painted or unpainted. Imports of these products are generally classified under HTSUS 3925.20.0010 and may also be classified under 4418.29.4000, 4418.29.8030, 4418.29.8060, or 7019.90.5150.
Country‑of‑Origin and Third‑Country Processing Rule
Commerce stated that the country of origin of a fiberglass door panel is determined by where the fiberglass door skin is pressed, and processing in a third country (for example, trimming, painting, or assembly) does not remove the product from the scope of the orders. That means panels where the skin was pressed in China remain covered even if further processed elsewhere.
