• The Trump administration is preparing to set a price floor and impose tariffs on imports of polysilicon and derivative products used in chips and solar panels, according to sources.
  • The move aims to protect domestic producers but could raise costs for solar and semiconductor manufacturers.
  • The policy, still in development, may face legal and diplomatic challenges.

Potential Trade Action

The Trump administration is preparing to set a price floor and impose tariffs on imports of polysilicon and derivative products used in chips and solar panels, according to people familiar with the matter. The exact scope and timing of the measures remain unclear, but officials are considering options under Section 232 of the Trade Expansion Act, which allows the president to restrict imports for national security reasons.

Polysilicon is a key raw material for solar panels and semiconductors. Most global production is concentrated in China, with significant capacity also in Germany, Malaysia, and the United States. A price floor would establish a minimum price for imports, effectively taxing cheaper foreign supplies, while tariffs would add an additional cost on top.

"The goal is to level the playing field for American manufacturers," said a senior administration official, speaking on condition of anonymity. "We've seen a surge of cheap imports that threaten our domestic industry and our national security."

The Commerce Department is reportedly drafting the details, including which product categories would be covered and how the price floor would be calculated. A formal announcement could come within weeks, though officials caution that the timeline is fluid.

Industry Reactions

The potential policy has drawn mixed reactions. Domestic polysilicon producers, such as Hemlock Semiconductor and REC Silicon (REC), have long complained about unfair competition from Chinese state-subsidized rivals. "We are encouraged by the administration's commitment to enforcing trade laws and protecting American jobs," said a spokesperson for Hemlock.

However, downstream users of polysilicon, including solar panel manufacturers and chipmakers, warn that the tariffs would increase costs and disrupt supply chains. "This could raise the cost of solar deployment significantly and hurt American competitiveness in clean energy," said a representative of the Solar Energy Industries Association.

Shares of major solar companies were mixed in early trading, with US-based producers seeing modest gains, while overseas-focused firms slipped.

Legal and Diplomatic Hurdles

The move is likely to face legal challenges. Importers and foreign governments may argue that the measures violate World Trade Organization rules. "A price floor is an unusual mechanism and could be difficult to justify under international law," said a trade lawyer not involved in the case.

Diplomatically, the tariffs could exacerbate tensions with China, which retaliated against previous US tariffs with its own duties on American goods. European and Asian allies are also watching closely, as they have significant polysilicon exports to the US.

"The administration is sensitive to these concerns, but national security considerations are paramount," said the official.

Next Steps

Once formally proposed, the measures would be subject to a public comment period before being finalized. The administration could also adjust the tariff rates or price floor based on the outcome of negotiations with key trading partners.

For now, industry analysts advise companies to prepare for potential disruption. "This is a significant development that could reshape the supply chain," said Clean Energy Associates, a consultancy.
