The U.S. Court of International Trade denied GameChange Solar Corp.'s motion for judgment on the agency record in Court No. 24-00174, upholding Commerce's final scope ruling that the company's off-grid solar charging module is within the scope of the 2012 antidumping and countervailing duty orders on crystalline silicon photovoltaic cells from China. In Slip Op. 26-125, Judge Timothy C. Stanceu found the plain scope language dispositive and rejected GameChange's arguments that Commerce failed to identify specific scope language and that the consumer good and off-grid CSPV panel exclusions applied.
The USITC determined on October 13, 2026 that revocation of the antidumping and countervailing duty orders on mattresses from Cambodia, China, Malaysia, Serbia, Thailand, Turkey and Vietnam would be likely to lead to continuation or recurrence of material injury within a reasonably foreseeable time. The existing antidumping duty orders on Cambodia, Malaysia, Serbia, Thailand, Turkey and Vietnam and the existing countervailing duty order on China remain in place. The reviews, Inv. Nos. 701-TA-645 and 731-TA-1495 and 1497-1501 (Review), were instituted on April 1, 2026 and conducted on an expedited basis; the USITC's report, Publication 5803, will be available on its website by November 19, 2026.
China's anti-involution campaign against below-cost competition in solar manufacturing now combines CPIA's standardized cost-accounting model, an Aug. 6 pledge by eight polysilicon producers representing more than 90% of effective capacity to price at or above full cost, and three mandatory national standards taking effect Jan. 1, 2027. The standards cap polysilicon energy consumption at 6.3 kg of standard coal equivalent per kilogram and set minimum Grade 3 module conversion efficiency of 23.2% for TOPCon and HJT and 23.5% for BC. The Silicon Industry Branch estimates effective polysilicon capacity will fall to about 2.4 million MT after restructuring, 16.4% below end-2024 levels.
China's N-type M10 and 210R wafer FOB prices were unchanged week on week at $0.149/pc and $0.153/pc, per the OPIS Global Solar Markets Report released Oct. 6, with wafer inventories estimated at around 25 GW. A temporary final rule issued in late September by the U.S. Department of Commerce's Bureau of Industry and Security restricts stockpiling of polysilicon and polysilicon derivatives ahead of Section 232 import adjustments taking effect Dec. 4, 2026, covering imports during the transition period from Sept. 22 to Dec. 3.
The USITC voted to institute a Section 337 investigation, Inv. No. 337-TA-1526, into certain vertical power delivery systems, components thereof, and computing systems containing the same, based on a complaint filed on behalf of Vicor Corporation of Andover, Massachusetts, on September 9, 2026 and supplemented on September 10, 2026. The complaint alleges infringement of certain patent claims through importation and sale of the products, and Vicor requests a limited exclusion order and cease and desist orders.
The U.S. Court of International Trade remanded Commerce's antidumping and countervailing redeterminations in the investigations of freight rail couplers from China, Court No. 23-00160 and Court No. 23-00161, in Slip Op. 26-122 dated October 8, 2026. The court found Commerce again failed to adequately explain its decision not to exclude attached freight rail couplers from the scope and did not reasonably address Wabtec's argument that attached couplers cannot cause cognizable injury. Commerce had continued to find on remand that attached couplers were properly included in the scope of the orders.

The U.S. Department of Commerce issued a temporary final rule restricting stockpiling of polysilicon and its derivatives ahead of Section 232 import adjustments taking effect on Dec. 4, 2026, covering imports during the transition period from Sept. 22 to Dec. 3. The rule followed trade data showing a sharp increase in polysilicon imports after the Section 232 measures were released in early August. One market participant said the rule could curb China-origin wafers, cells and modules entering through circumvention channels involving smaller traders and companies, with limited direct impact on global polysilicon demand.

The correction adds clear notice that liquidation of entries of these unfinished fittings will be retroactively suspended.
