All tariff and compliance developments for solar imports: AD/CVD, Section 201, 232 and 301, UFLPA, FEOC and filing requirements for modules, cells, polysilicon, solar glass and inverters.
BIS issued a temporary final rule, effective September 22, 2026 through December 3, 2026, setting the criteria and process it will use to monitor existing companies for evidence of stockpiling polysilicon and polysilicon derivatives ahead of import adjustments effective December 4, 2026 under Proclamation 11052. The rule limits a newly established importer's ability to stockpile, imposes import limitations on new importers that register with CBP on or after August 6, 2026, and subjects companies found to be stockpiling to an import prohibition if necessary. It also establishes the process for such companies to obtain a waiver from any import prohibitions imposed under the rule.
Why it matters: Importers of polysilicon and polysilicon derivatives, including new importers that registered with CBP on or after August 6, 2026, face stockpiling monitoring, import limitations and possible import prohibitions through December 3, 2026.
The Canadian International Trade Tribunal rescinded its order concerning photovoltaic modules and laminates originating in or exported from China under subsection 76.03(2) and subparagraph 76.03(12)(a)(iii) of the Special Import Measures Act, so anti-dumping and countervailing duties no longer apply to new releases of covered goods. The CBSA will automatically refund these duties on eligible goods released on or after March 25, 2026, and any outstanding re-determination process for those goods will be terminated. Goods released before March 25, 2026 are not eligible for a refund, and assessments and reassessments relating to those earlier releases will continue.
Why it matters: Importers of photovoltaic modules and laminates from China released on or after March 25, 2026 receive automatic refunds of anti-dumping and countervailing duties, while goods released earlier remain subject to continuing assessments and any outstanding re-determination deadlines.
The Canadian International Trade Tribunal terminated the expiry review of its March 25, 2021 order in expiry review RR-2020-001, concerning the dumping and subsidizing of certain photovoltaic modules and laminates from China, and rescinded that order. The Canada Border Services Agency will therefore not continue to impose anti-dumping and countervailing duties on these goods.
Why it matters: Anti-dumping and countervailing duties on certain photovoltaic modules and laminates from China will no longer be imposed following the CITT's rescission of its order in RR-2020-001.

The Canadian International Trade Tribunal completed an interim review (RD-2025-001) of its March 25, 2021 order in expiry review RR-2020-001 on photovoltaic modules and laminates originating in or exported from China, and amended the order to exclude flexible photovoltaic modules affixed to curved vehicle surfaces, such as transport truck fairings, with a power output not exceeding 200 W. The Tribunal continues the order as amended.
The Canadian International Trade Tribunal initiated an expiry review of its March 25, 2021 order, in expiry review RR-2020-001, on photovoltaic modules and laminates from China, to determine whether expiry of the order is likely to lead to continued or resumed dumping or subsidizing and injury to the domestic industry. The Canada Border Services Agency will determine by July 2, 2026 whether there is a likelihood of resumed or continued dumping or subsidizing; if positive, the Tribunal will determine by December 9, 2026 whether that is likely to result in injury.
