The US Department of Commerce has decided to continue with the existing AD/CVD duties on crystalline silicon PV products from China and Taiwan
Its sunset review determined that revoking these measures would likely lead to continued dumping and countervailable subsidies
The AD/CVD orders, first imposed in February 2015, were reviewed under a 2nd sunset review launched in August 2025
The US Department of Commerce (DOC) has decided to continue imposing existing antidumping and countervailing duties (AD/CVD) on solar imports from China and Taiwan following an expedited sunset review.
In its final assessment, the DOC said that revoking AD duties on imports of crystalline silicon PV products from China and Taiwan would likely result in continued or recurring dumping at margins of 165.04% for China and 27.55% for Taiwan.
Similarly, in the case of CVD revocation, there will likely be a continuation or recurrence of countervailable subsidies at rates ranging within 29.72% and 41.57%, ruled the DOC.
The department issued AD/CVD orders on solar imports from the 2 named countries in February 2015, and launched a 2nd sunset review into the orders in August 2025.
These determinations from the DOC come on the heels of the department imposing CVD of 117.41% on solar cell and module imports from 3 Chinese manufacturers in January 2026 and setting a 9.07% rate for other non-reviewed companies (see US: Over 117% Countervailing Duties On Chinese Solar Imports).
China also recently extended AD duties on solar-grade polysilicon imports from the US and South Korea until 2031 for a period of 5 years (see China Extends Anti-Dumping Duties On US, South Korean Polysilicon).
Meanwhile, the US administration has reportedly disassociated itself from an appeal against the US Court of International Trade (CIT) ruling to retroactively collect tariffs on imported solar panels that entered the country during the 2-year moratorium period (April 2022 to June 2024). The industry will now continue to fight the ruling. An adverse decision could be significantly damaging for solar developers.
Notably, the Biden administration had granted a 24-month solar tariff moratorium on Southeast Asian imports, but the CIT had invalidated the move, triggering fear of retroactive tariffs being collected worth several billions (see ‘Billions’ In Retroactive Solar Tariffs Possible After US Court Decision).
