The U.S. International Trade Commission voted to maintain trade protections on crystalline silicon photovoltaic products. The targeted trade penalties “counteract foreign market distortions” by applying antidumping duties on underpriced imports and countervailing duties to offset foreign government subsidies.  

Initial duties established during the original 2014 investigations reached rates as high as 165% for certain Chinese entities and 44% for Taiwanese exporters, though annual administrative reviews frequently adjust the exact assessment margins for individual manufacturers.  

Commission members determined that revoking these current antidumping and countervailing duty orders for Chinese solar imports, alongside the antidumping duty on Taiwanese imports, would cause material injury to domestic manufacturers to continue or recur.  

Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns voted in favor of the continuation during an expedited five-year sunset review. The regulatory history of this mechanism dictates that the Department of Commerce must lift trade penalties after five years unless both agencies conclude that termination would harm the domestic sector. 

The Uruguay Round Agreements Act mandates this five-year review process to ensure trade protections remain necessary. Federal officials instituted this specific review cycle on August 1, 2025. By December 22, 2025, the commission voted to accelerate the timeline into an expedited review after finding that responses from domestic manufacturers were sufficient, while participation from foreign respondents was insufficient to warrant full hearings.  

During that December session, Chair Karpel and Commissioner Kearns voted to expedite the proceedings for both nations due to the unbalanced participation. Commissioner Johanson registered a dissenting vote on the procedural format, choosing instead to support full reviews for both target markets. 

The investigation covers crystalline silicon photovoltaic cells, modules, laminates, and panels under investigation numbers 701-TA-511 and 731-TA-1246-1247. The continuation preserves the dual antidumping and countervailing duty framework for Chinese shipments, which addresses both product dumping and foreign state subsidies, as well as the singular antidumping framework applied to Taiwanese shipments.  

The regulatory body plans to publish its report containing the underlying evidence and staff findings by July 6, 2026, under publication number 5748.
