Wooden Fence Components from China: AD/CVD investigations
Commerce opened antidumping and countervailing duty investigations into wooden fence pickets and panels from China on November 3, 2026, the first step toward wood fence tariffs. The petition alleges dumping margins of 109.01% to 232.23%, and Commerce is examining 37 alleged Chinese subsidy programs.
Wood fence tariffs: the key numbers
These are the figures in the two initiation notices published November 9, 2026. No duties apply yet, and the margins are the petitioner's estimates, not final rates.
109.01% to 232.23%: alleged dumping margins
The range depends on which country Commerce uses to value Chinese costs. The petition estimates 109.01% to 117.41% with Türkiye, 122.64% to 131.81% with Mexico, and 217.40% to 232.23% with Brazil.
37 subsidy programs: the countervailing duty case
Commerce found enough evidence to investigate 37 programs the petition says the Chinese government uses to subsidize fence makers. China filed written remarks instead of holding consultations.
80 Chinese companies named
The petition lists 80 Chinese producers and exporters. Commerce will pick the largest from CBP entry data and send them quantity and value questionnaires.
3 US mills behind the petition
The American Alliance of Wooden Fence Producers filed on September 24, 2026. Its members are Alta Forest Products, Sierra Pacific Industries and Mendocino Forest Products.
Surrogate country: because Commerce treats China as a nonmarket economy, it values Chinese production costs using prices from another country.
What fence pickets and panels are covered, by HTS number
The case began as "wooden fence pickets" and was renamed "certain wooden fence components" on November 3. The scope covers pickets on their own and pickets built into panels.
Most covered pickets are Japanese cedar (sugi), but other woods count too. These include Western Red Cedar, Redwood, Douglas Fir, Western Hemlock, Sitka Spruce and Chinese fir.
Size: finished pickets up to 1 inch thick and 12 inches wide, and at least 3 feet long. Most are 5, 6 or 8 feet.
Shapes and finishes: flat top, pointed, dog ear, gothic and stockade styles are all in. So are painted, stained and pressure-treated pickets.
Panels and kits: pickets attached to rails, fully pre-assembled fence panels, bundles and kits with framing lumber are all covered.
Third-country processing: Chinese pickets that are cut, sanded or planed in another country remain covered.
Excluded: pickets made only of bamboo, Brazilian (Paraná) pine or Southern Yellow Pine. Wood mouldings already under the 2021 millwork orders are also out.
Imports usually enter under HTSUS 4404.10.0040, 4407.19.0092, 4421.99.7020 and 4421.99.7040. The written scope decides coverage; the HTS numbers are listed for convenience only.
Why the fence pickets case matters for importers
Every alleged dumping margin is above 100% of entered value. Final duties anywhere near that level would more than double the cost of entering Chinese pickets and panels.
The petitioners claim Chinese imports gained market share, undersold US pickets and cut US production, shipments and jobs. Commerce found these claims adequately supported to start the case.
The third-country processing clause matters too. Moving only the final cutting or sanding outside China won't take pickets out of scope.
What comes next in the wood fence tariffs case
The ITC must vote within 25 days of Commerce's notice on whether there's a reasonable sign of injury. That points to late November 2026, and a "no" vote would end both cases.
If the ITC votes yes, Commerce's preliminary subsidy decision is due about January 8, 2027, and its preliminary dumping decision about March 24, 2027. Either can be postponed.
Cash deposits would start only after an affirmative preliminary decision. That is when importers would begin paying at the border.
Key dates
September 24, 2026: Petition filed. The Alliance filed AD and CVD petitions with Commerce and the ITC.
November 3, 2026: Investigations opened. Commerce initiated cases A-570-243 (dumping) and C-570-244 (subsidies).
November 23, 2026: Scope comments due. Comments on product coverage are due by 5:00 p.m. ET, with rebuttals by December 3.
Late November 2026 (estimate): ITC preliminary vote. The ITC has 25 days from Commerce's notice.
January 8, 2027: CVD preliminary determination. Commerce is scheduled to issue its preliminary subsidy decision, unless postponed.
March 24, 2027: AD preliminary determination. Commerce is scheduled to issue its preliminary dumping decision, unless postponed.
How to check if wood fence tariffs apply to your imports
Check the wood species. Sugi, cedar, fir, hemlock, spruce and redwood are covered. Pure bamboo, Paraná pine and Southern Yellow Pine are excluded.
Measure the pickets. Covered pickets are no more than 1 inch thick and 12 inches wide, and at least 3 feet long.
Review your HTS codes. Flag entries under 4404.10.0040, 4407.19.0092, 4421.99.7020 and 4421.99.7040, but confirm against the written scope.
Trace the origin. Ask suppliers outside China whether the pickets started as Chinese wood products. Light processing elsewhere won't remove them from scope.
Plan for deposits. Budget for possible cash deposits from early 2027, and file scope comments by November 23 if your product sits near the edge.
Frequently asked questions
Are there tariffs on wood fence pickets from China now?
Not under this case yet. Commerce has only opened the investigations, and deposits would start after an affirmative preliminary determination.
Do wood fence tariffs cover pre-assembled fence panels?
Yes. The scope covers pickets attached to rails or framing, including fully pre-assembled fence panels and kits.
Are cedar fence pickets included?
Yes. Japanese cedar (sugi) is the most common species named, and Western Red Cedar and Incense Cedar are listed too.
What is an antidumping duty?
It is a duty on imports sold in the US below fair value. A countervailing duty offsets foreign government subsidies, and the two can apply together.
