On September 24, 2026, the American Alliance of Wooden Fence Producers, comprised of Alta Forest Products, Mendocino Forst Products, and Sierra Pacific Industries, (“Petitioner”) filed companion petitions requesting the imposition of antidumping and countervailing duties on imports of certain wooden fence pickets from the People’s Republic of China (“China”).
SCOPE OF THE INVESTIGATION
The proposed scope of these investigations is as follows:
The scope of this investigation includes certain wooden fence pickets, finished and unfinished, whether assembled or unassembled. Wooden fence pickets included in this scope are typically made from Cryptomeria japonica (Japanese Cedar or Sugi), but can also be made from other wood species, including but not limited to Western Red Cedar, Redwood, Incense Cedar, Douglas Fir, Western Hemlock, Sitka Spruce, and Cunninghamia lanceolata (Chinese Fir). Wooden fence pickets are included within the scope of this investigation regardless of form or shape, including, but not limited to square, pointed, dog ear, flat top, and gothic.
The finished products covered by the scope of this investigation have the following dimensions: a thickness of no more than 1 inch, a width of no more than 12 inches, and a length of at least 3 feet. The products covered by the scope are typically a length of 5 feet, 6 feet, or 8 feet when finished.
Wooden fence pickets are included within the scope of the investigation regardless of whether they have been painted, stained, pressure-treated, or otherwise coated or treated. Subject merchandise also includes wooden fence pickets that have been further processed in a third country, including but not limited to trimming, cutting, notching, sanding, planing or any other processing that would not otherwise remove the merchandise from the scope of the investigation if performed in the country of manufacture of the in-scope product.
Excluded from the scope of the investigation are wooden fence pickets made exclusively of bamboo, Brazilian Pine (Paraná pine), or Southern Yellow Pine (including Shortleaf Pine (Pinus echinata), Slash Pine (Pinus ellioti), Longleaf Pine (Pinus palustris), or Loblolly Pine (Pinus taeda)). Also excluded are wood mouldings and millwork products covered by the antidumping and countervailing duty orders on wood mouldings and millwork products from China.
Imports of subject merchandise are typically classified under Harmonized Tariff Schedule of the United States (HTSUS) statistical numbers 4404.10.00.40, 4407.19.00.92, 4421.99.70.20, and 4421.99.70.40. References to the HTSUS classification in this petition are provided for convenience and customs purposes, and the written description of the merchandise under investigation is dispositive regarding the scope of the investigation.
