Trump administration imposes new tariffs on polysilicon
The second Trump administration has been far from a friend to the renewable energy space, enacting the One Big Beautiful Bill Act (OBBBA), imposing tariffs on solar-related components, and adding heavy FEOC restrictions on the U.S. manufacturing landscape.
On Aug. 6, the sitting President’s policy on energy reared its head once again, although it came in a way that could have both positive and negative consequences for American solar.
In a proclamation titled ‘Adjusting Imports of Polysilicon and its Derivatives into the United States,’ already commonly known as the ‘Section 232 Tariffs,’ President Trump issued a minimum import price on polysilicon. Of course, this material is a fundamental building block of electronic semiconductors present in a number of industries, and also the key ingredient in many modern solar panels.
“Polysilicon is the base material underpinning the security of America’s semiconductor and solar-power supply chains,” Trump writes. “Yet for decades, America has allowed foreign countries to weaken United States producers in the polysilicon sector ‑- eroding our economic and national security. Today, I am taking action to put a stop to these practices and revitalize the United States polysilicon sector.”
The proclamation also states that there will be a 15% tariff on products made with polysilicon materials, in an effort to support American production of those key components. Trump says that foreign governments have “designed policies to increase the production of these products in their countries, which have come at the expense of the United States industry.” He further posits that these aforementioned governments have been doing so for decades.
Additionally, Trump has ordered Secretary of Commerce Howard Lutnick and his department to establish and oversee an incentive program for companies looking to produce polysilicon on American shores. These incentives also extend to expansion of polysilicon factories, or the manufacturing of its derivative products in the U.S.
The solar industry reacts
Throughout the second Trump administration, the solar industry has been ready and willing to roll with most potential punches. The Section 232 Tariffs could come as a big blow to the industry in the U.S., as the country currently only produces about 2% of the world’s polysilicon. China, in contrast, produces about 90%.
Tim Pawlenty, president and CEO of the Solar Energy Industries Association (SEIA), says his organization and the American Clean Power Association have already collectively filed joint comments regarding the Trump administration’s recent decision. Pawlenty adds these comments include “recommendations for alternative solutions for growing domestic polysilicon manufacturing.”
“America has made terrific progress rebuilding its solar manufacturing base,” Pawlenty says, “but imposing tariffs and prices floors on solar materials will create new challenges for American manufacturers and raise energy costs for families and businesses.”
Aaron Hall, president of solar and battery software company Anza, also spoke out against the new measures in an Aug. 6 statement. He says the new policy “changes the economics of solar procurement overnight,” citing solar wafers as the hardest hit sector of the manufacturing space.
However, he adds that this could become a boon to American manufacturing.
“Developers are now facing higher equipment costs, while many will also be pushed toward domestic PERC products because there simply aren’t enough domestic TOPCon options available today,” Hall says. “That means some projects will no longer pencil under the new economics, but we also expect this policy to become a major catalyst for U.S. manufacturing.
“The biggest story is surprisingly not modules, it’s wafers. Domestic wafer production has become dramatically more valuable overnight, and we expect to see significant new investment in that part of the supply chain over the next six months.”
