Court Flips Canadian Wind Tower Tariffs After Six Years
Published Date: 6/25/2026
Notice
Summary
The U.S. Department of Commerce is changing the antidumping duty rates on Canadian utility-scale wind towers after a court decision. This affects Marmen Inc. and Marmen Énergie Inc., the main companies involved, and updates the fees they must pay for imports from July 2018 to June 2019. These changes take effect on June 25, 2026, potentially impacting costs for importers and manufacturers.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Antidumping Rate Reduced to 2.93%
If you import utility-scale wind towers from Canada (subject merchandise), the weighted-average dumping margin assigned to Marmen Inc./Marmen Énergie Inc. and to "All Others" is changed from 4.94 percent to 2.93 percent. This amendment applies to the period of investigation July 1, 2018, through June 30, 2019 and is effective June 25, 2026.
Revised Cash Deposit Instructions Issued
Commerce will issue revised cash deposit instructions to U.S. Customs and Border Protection because Marmen does not have a superseding cash deposit rate. The revision follows the amended final determination (2.93%) and is applicable June 25, 2026.
Court Notice Triggers Liquidation Suspension
Under Timken and related precedent, Commerce must publish a notice when a court decision is not "in harmony" with its final determination and must suspend liquidation of entries pending a conclusive court decision. The U.S. Court of International Trade issued a final judgment on June 15, 2026 that is not in harmony with Commerce's original final determination, and Commerce published this notice on June 25, 2026.
