Proclamation: Adjusting Imports of Polysilicon and its Derivatives into the United States
Summary
This proclamation invokes Section 232 of the Trade Expansion Act to impose a minimum import price (MIP) program on polysilicon and its derivatives, a 15% ad valorem tariff on polysilicon derivatives, and directs the Secretary of Commerce to offer incentives for domestic production. It aims to protect and revive the U.S. polysilicon industry by restricting imports that threaten national security, particularly for semiconductor and solar supply chains.

Key Takeaways
- 1.Establishment of a minimum import price (MIP) program for polysilicon and its derivatives to create a protected domestic market.
- 2.Imposition of a 15% ad valorem duty on imports of polysilicon derivatives, replacing an expired safeguard tariff.
- 3.Authorization for the Secretary of Commerce to offer incentives for companies investing in U.S. production of polysilicon and polysilicon derivatives.
- 4.Authority for the Secretary and USTR to negotiate adjustments with trading partners that adopt equivalent import-adjusting actions.
Market Implications
The action is bullish for U.S. polysilicon producers and domestic solar/semiconductor manufacturers by raising import costs and encouraging onshoring, but bearish for foreign polysilicon exporters and companies reliant on imported polysilicon derivatives.
⚡ Government Convergence
Active government convergence in this signal’s sector right now.
Over the last 90 days, 7 separate government actions have converged on Semiconductors / Onshoring. What that means: federal dollars are already moving — agencies are soliciting bids and awarding contracts, not just talking, and legislation and executive action are building the policy and funding tailwind behind it. When independent channels move together like this — 3 patents, 1 bills, 1 procurement notices, 1 insider buys and 1 congressional trades — it's the clearest early tell that Washington is committing to semiconductors / onshoring, the kind of build-up that reshapes the sector well before it's obvious in the headlines.

To Facilitate Positive Adjustment to Competition from Imports of Quartz Surface Products
This proclamation imposes a 4-year tariff-rate quota on imports of quartz surface products (QSP) to protect the domestic industry from serious injury caused by increased imports. It excludes Canada, Mexico, Australia, CAFTA-DR countries, Colombia, Israel, Jordan, Korea, Panama, Peru, Singapore, and CBERA beneficiaries, and provides a developing-country exemption. The action is a safeguard measure under section 202 of the Trade Act of 1974.
Presidential Determination Pursuant to Section 101 of the Defense Production Act of 1950, as Amended, on Recoverable Critical Minerals and Materials
This memorandum invokes the Defense Production Act (DPA) Section 101 to declare that recoverable critical minerals and materials (such as black mass, end-of-life rare-earth magnets, and scrap) are essential to national defense and that the U.S. cannot meet defense needs without disrupting civilian markets. It directs the Secretary of Commerce to issue regulations and take actions—including priority contracts and supply-chain interventions—to rapidly expand domestic recovery and processing of these materials, while explicitly excluding copper scrap already covered by a separate proclamation.
