The U.S. solar market has entered a new trade regime. Final antidumping and countervailing duty determinations on crystalline‑silicon cells and modules from Cambodia, Malaysia, Thailand and Vietnam—paired with stepped‑up forced‑labor enforcement—are resetting price, risk and schedules across the utility‑scale pipeline. (Trade.gov)
What changed: The Commerce Department issued final AD/CVD determinations on April 21, 2025, and the U.S. International Trade Commission delivered its final injury/threat findings on May 20, 2025, clearing the way for formal duty orders. On June 24, 2025, Commerce published AD and CVD orders in the Federal Register. The ITC found material injury for Malaysia and Vietnam and threat for Cambodia and Thailand, which governs how and from when duties are assessed on unliquidated entries. (Trade.gov)
Enforcement backdrop: In parallel, the Department of Homeland Security’s 2025 update on the Uyghur Forced Labor Prevention Act (UFLPA) reports that since the rebuttable presumption took effect in June 2022, CBP has examined more than 16,700 shipments and denied more than 10,000. Trade reporting shows a pronounced uptick in electronics detentions since mid‑2025, a category that often includes solar cells, modules and certain battery components. Together, the duty orders and UFLPA checks are tightening inbound supply. (Department of Homeland Security)
Why it matters for utility‑scale: In the near term, developers face longer procurement lead times, heightened traceability burdens, and more volatile delivered pricing as suppliers adjust routing and documentation. Over the medium term, the combination of tariffs and forced‑labor compliance is pushing buyers toward diversified portfolios and greater U.S. content, aligning with domestic‑manufacturing incentives but demanding more rigorous contract language on origin, audits and schedule relief. The new orders’ scope language also matters: it captures both cells and modules, with exclusions narrowly drawn and cross‑references to existing 2012 China CSPV orders. (Federal Register)
Bottom line: Policy risk is now procurement risk. Sponsors should stress‑test EPC schedules for port delays, confirm supplier bill‑of‑materials traceability to the polysilicon level, and revisit commercial terms (price adjusters, liquidated damages, substitution rights) to keep 2026–2027 CODs on track. The structural effect is clear: less reliance on Southeast Asia, more scrutiny at the border, and a faster pivot to domestic or fully traceable supply.
