The US Department of Commerce has extended its antidumping and countervailing duty orders on wood mouldings and millwork products from China, with weighted-average dumping margins of up to 231.60 per cent and countervailable subsidy rates of up to 252.29 per cent, locking the duty wall in place until 5 May 2031. That is according to the final results of the expedited first sunset reviews published in the Federal Register on 5 May 2026, with case A-570-117 entering its second five-year cycle and the Government of China declining to engage in either review.
Commerce published the underlying antidumping and countervailing duty orders on 16 February 2021, after an investigation that found Chinese subsidy rates ranging from 20.56 per cent to 252.29 per cent and dumping margins reaching 231.60 per cent against named Chinese exporters. The 2021 orders followed a Coalition of American Millwork Producers petition lodged on 8 January 2020 by Wiley Rein partner Timothy Brightbill, who said at the petition filing that Chinese producers were “taking jobs away from hard-working Americans,” with US imports of Chinese wood mouldings and millwork having been valued at US$193 million in 2019.
Commerce initiated the first sunset reviews on 2 January 2026 and proceeded on the expedited 120-day pathway after the Coalition lodged a timely substantive response, and no Chinese interested party filed a reply. Wood Central understands that the absence of a Chinese respondent submission triggered the expedited schedule, with the standard sunset review otherwise running for 240 days under Commerce’s regulations.
The current nine-member coalition comprises Best Moulding Corporation, Bright Wood Corporation, Cascade Wood Products, Endura Products, Menzner Lumber & Supply Company, Pacific Wood Laminates, Sierra Pacific Industries, Sunset Mouldings and Woodgrain Millwork, with founding member Yuba River Moulding having exited since the original 2020 petition. The petitioner roster has expanded from seven companies at filing to ten at the 2021 ITC injury determination and now nine at the 2026 sunset review milestone.
Named Chinese exporters caught inside the duty wall include Fujian Yinfeng Imp & Exp Trading and Mangrove Forest Industries, Longquan Jiefeng Wood Industry and Zhejiang Senya Board Industry, Fujian Jinquan Trade Co., Bel Trade Wood Industrial Co. of Youxi, Fujian, and Fujian Province Youxi County Baiyuan Wood Machining. Commerce’s 24 February 2026 final results of the 2023–2024 administrative review confirmed that Yinfeng/Mangrove and Longquan Jiefeng/Senya Board continued to sell wood mouldings into the US at prices below normal value, with US importer Jeld-Wen having withdrawn its review request in June 2024 and 38 named producer-exporters having sat under Commerce’s parallel countervailing duty review for the 2023 period.
It comes as Wood Central reported the US Department of Commerce slapping a 187.27 per cent preliminary antidumping duty on Chinese hardwood plywood on 2 March 2026, with combined antidumping and countervailing duties on Chinese plywood now running at around 267 per cent, and Chinese hardwood plywood imports having collapsed from 2 million cubic metres in 2016 to just 52,800 cubic metres last year.
The mouldings ruling repeats that posture, with Section 301 List 3 tariffs of 7.5 per cent and the 10 per cent Section 122 global baseline signed by President Donald Trump on 20 February 2026, stacking on top of the antidumping and countervailing duty regime, and Vietnam, Indonesia and Malaysia now absorbing the rerouted Chinese millwork capacity that Brightbill and the Coalition first targeted six years ago.
With Commerce rejecting revocation through its expedited 120-day finding on both the antidumping and countervailing duty orders, case A-570-117 carries into its second five-year cycle from 5 May 2026, the same Coalition of American Millwork Producers case that took US imports of Chinese mouldings from US$193 million in 2019 to a duty wall standing at up to 231.60 per cent and 252.29 per cent today.
