Antidumping Duties and Entry Suspension
Commerce will require U.S. Customs and Border Protection (CBP) to continue suspending liquidation of imports of fiberglass door panels from China for entries on or after January 22, 2026, and to require cash deposits of estimated antidumping duties. This determination is published as applicable June 15, 2026, and the suspension and cash deposit requirements will remain in effect until further notice.
Company-Specific Cash Deposit Rates
Commerce established estimated weighted-average dumping margins (cash deposit rates) for specific China producers/exporters: Anhui Xinyu Fiberglass Door Co., Ltd. — 73.07% (72.94% adjusted); Wuxi Lutong Fiberglass Doors Co., Ltd. — 73.07% (72.94% adjusted); Dalian Capstone Engineering Co., Ltd. — 41.82% (41.79% adjusted); Jiangxi Fangda Tech Co., Ltd. group — 104.31% (104.08% adjusted); China-wide entity — 147.85% (147.82% adjusted).
Third-Country Exporter Deposit Rule
For third-country exporters of the subject merchandise, the cash deposit rate will be the rate applicable to the Chinese producer/exporter that supplied that third-country exporter; if that producer/exporter does not have its own rate, the China-wide rate applies. Commerce will apply these rules when instructing CBP on required cash deposits.
Products Covered and HTSUS Classifications
The duty order covers fiberglass door panels and sidelites (finished or unfinished, assembled or unassembled, pre-hung or in an entry door system) defined in Appendix I, with the primary HTSUS classification 3925.20.0010 and additional possible subheadings 4418.29.4000, 4418.29.8030, 4418.29.8060, and 7019.90.5150. The written scope description in Appendix I controls what is covered.
ITC Injury Decision and Possible Refunds
Commerce will notify the U.S. International Trade Commission (ITC), which has 45 days to determine whether U.S. industry is materially injured or threatened by imports of these door panels. If the ITC finds no material injury, the proceeding is terminated, suspension of liquidation will be lifted, and all cash deposits will be refunded or canceled; if the ITC finds injury, Commerce will issue an antidumping duty order and CBP will assess duties on entries as described.
