US Sets Tariffs and Minimum Prices on Imported Polysilicon and Solar Equipment
The United States is introducing new trade measures for imported polysilicon, solar panels and related components as part of an effort to shift more clean-energy manufacturing into the domestic market.
The Wall Street Journal reported that President Donald Trump signed a proclamation setting a 15% tariff on imports of covered solar-energy materials and equipment.
The measures are scheduled to take effect on 4 December 2026. Companies that commit to building manufacturing facilities in the United States will be able to apply for exemptions from the tariffs.
Minimum import prices will accompany the tariff
The policy goes beyond a conventional import duty.
The proclamation will also establish minimum prices for solar components. Importers will be required to certify that the first sale of imported polysilicon and covered solar products to another company does not fall below the minimum import price.
The stated purpose is to prevent products from entering the country at one declared price and then being resold below the price floor.
The measures apply to industrial materials and equipment used across the solar manufacturing chain, including:
- imported polysilicon
- solar panels
- solar components
- polysilicon ingots
- wafers used to make solar cells
Polysilicon ingots are sliced into wafers, which are then used in solar cells and assembled into modules.
Trade terms may become more important than headline prices
The policy is intended to reduce Chinese control of a material considered critical for solar systems and semiconductors and to encourage manufacturing investment in the United States.
For industrial-material buyers, the relevant variables now include not only product price and specification but also tariff treatment, minimum-price compliance, manufacturing commitments and the date on which new rules apply.
The source reports the trade-policy framework; it does not provide a new market price for polysilicon or quantify the final landed-cost impact.
