This means importers of these solar cells might face extra duties starting September 16, 2026, to keep things fair for American businesses. If you’re involved in importing or selling these solar cells, get ready for some changes that could affect costs and timing. ## Abstract The U.S. Department of Commerce (Commerce) determines that crystalline silicon photovoltaic cells, whether or not assembled into modules (solar cells), from the Lao People's Democratic Republic (Laos) are being, or are likely to be, sold in the United States at less than fair value (LTFV). The period of investigation (POI) is January 1, 2025, through June 30, 2025. ## Effects PRIA read - 65% Dumping Margin for Laos Solar Cells: cost, high. If you import crystalline silicon photovoltaic cells from Laos, Commerce determined an estimated weighted-average dumping margin of 65.43% and a cash deposit rate of 65.03% for Solarspace and the Laos‑wide entity for the period January 1, 2025 through June 30, 2025. Commerce assigned the same 65.43… - Suspension of Liquidation from April 28, 2026: cost, high. Commerce will instruct U.S. Customs and Border Protection to suspend liquidation of all entries of the subject merchandise entered, or withdrawn from warehouse, for consumption on or after April 28, 2026 (the date the Preliminary Determination published). The notice states that if the ITC later fin… - Critical Circumstances Finding, In Part: cost, medium. Commerce found that critical circumstances exist for the separate‑rate companies and the Laos‑wide entity, but does not find critical circumstances for Solarspace/SolarSpace Hong Kong, which Commerce treats as a single entity. This determination applies to the period January 1, 2025 through June 30… - Detailed Product Scope and Exclusions: mixed, medium. The investigation covers crystalline silicon photovoltaic cells of thickness equal to or greater than 20 micrometers and many modules, laminates, and panels, but explicitly excludes thin‑film products (amorphous silicon, CdTe, CIGS), cells permanently integrated into a consumer good not exceeding 1… - ITC 45‑Day Injury Determination Window: mixed, medium. The U.S. International Trade Commission will make its final determination on whether the U.S. industry is materially injured or threatened with material injury by imports of these Laos solar cells no later than 45 days after Commerce's final determination. If the ITC finds material injury, Commerce… ## Related documents - [2025-05481](https://policyrisk.com/federal-register/2025-05481): Regulations Enhancing the Administration of the Antidumping and Countervailing Duty Trade Remedy Laws; Correction, 2025-03-31 - [2026-20777](https://policyrisk.com/federal-register/2026-20777): Certain Paper Shopping Bags From Cambodia: Preliminary Results of Antidumping Duty Administrative Review; 2024-2025, 2026-10-09 - [2026-20779](https://policyrisk.com/federal-register/2026-20779): Passenger Vehicle and Light Truck Tires From Thailand: Preliminary Results and Rescission, in Part, of Antidumping Duty Administrative Revi…, 2026-10-09 - [2026-20778](https://policyrisk.com/federal-register/2026-20778): Certain Hot-Rolled Steel Flat Products From the Republic of Korea: Final Results of Countervailing Duty Administrative Review; 2023, 2026-10-09 - [2026-20690](https://policyrisk.com/federal-register/2026-20690): Oleoresin Paprika From India: Antidumping Duty Order and Countervailing Duty Order, 2026-10-08 - [2026-20691](https://policyrisk.com/federal-register/2026-20691): Certain Paper Shopping Bags From Taiwan: Preliminary Results and Rescission, in Part, of Antidumping Duty Administrative Review; 2024-2025, 2026-10-08 ## Sources - [2026-18941 on federalregister.gov](https://www.federalregister.gov/documents/2026/09/16/2026-18941/crystalline-silicon-photovoltaic-cells-whether-or-not-assembled-into-modules-from-the-lao-peoples) - [2026-18941 as published (PDF)](https://www.govinfo.gov/content/pkg/FR-2026-09-16/pdf/2026-18941.pdf) ## Related - [Previous: 2026-18940, Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled Into Modules F…](https://policyrisk.com/federal-register/2026-18940) - [Next: 2026-18942, Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled Into Modules F…](https://policyrisk.com/federal-register/2026-18942) - [All Federal Register documents](https://policyrisk.com/federal-register) Source: PRIA, https://policyrisk.com/federal-register/2026-18941 (as of 2026-09-23).
