New Antidumping and Countervailing Duty Petitions on Utility Scale Wind Towers from Canada, Indonesia, Korea, and Vietnam

By Douglas J. Heffner, Richard P. Ferrin and Jared A. Angle

The Wind Tower Trade Coalition (“petitioner”), on July 9, 2019, filed antidumping (AD) petitions on imports of certain utility scale wind towers from Canada, Indonesia, Korea, and Vietnam and countervailing duty (CVD) petitions on imports of certain utility scale wind towers from Canada, Indonesia, and Vietnam.

The U.S. AD law imposes special tariffs to counteract imports that are sold in the United States at less than “normal value.” The U.S. CVD law imposes special tariffs to counteract imports that are sold in the United States with the benefit of foreign government subsidies. For AD/CVD duties to be imposed, the U.S. government must determine not only that dumping and/or subsidies are occurring, but also that there is “material injury” (or threat thereof) by reason of the dumped and/or subsidized imports. Importers are liable for any potential AD/CVD duties imposed. In addition, these investigations could impact purchasers by increasing prices and/or decreasing supply of certain utility scale wind towers.


The merchandise covered by these petitions consists of certain wind towers, whether or not tapered, and sections thereof. Certain wind towers are designed to support the nacelle and rotor blades in a wind turbine with a minimum rated electrical power generation capacity in excess of 100 kilowatts and with a minimum height of 50 meters measured from the base of the tower to the bottom of the nacelle (i.e., where the top of the tower and nacelle are joined) when fully assembled.

A wind tower section consists of, at a minimum, multiple steel plates rolled into cylindrical or conical shapes and welded together (or otherwise attached) to form a steel shell, regardless of coating, end-finish, painting, treatment, or method of manufacture, and with or without flanges, doors, or internal or external components (e.g., flooring/decking, ladders, lifts, electrical buss boxes, electrical cabling, conduit, cable harness for nacelle generator, interior lighting, tool and storage lockers) attached to the wind tower section. Several wind tower sections are normally required to form a completed wind tower.

Wind towers and sections thereof are included within the scope whether or not they are joined with nonsubject merchandise, such as nacelles or rotor blades, and whether or not they have internal or external components attached to the subject merchandise.

Specifically excluded from the scope are nacelles and rotor blades, regardless of whether they are attached to the wind tower. Also excluded are any internal or external components which are not attached to the wind towers or sections thereof, unless those components are shipped with the tower sections.

Merchandise covered by this investigation is currently classified in the HTSUS under subheading 7308.20.00201  or 8502.31.0000.2  While the HTSUS subheadings are provided for convenience and customs purposes, the written description of the scope of the investigation is dispositive.

  • Canada: 46.32 percent to 57.70 percent
