TOYO will source polysilicon from an unidentified US manufacturer to lock in non-FEOC supply for its solar modules
The 1-year agreement, with an undisclosed supplier and volume, complements TOYO’s existing non-FEOC supply chain
The manufacturer says this deal aligns with US regulatory requirements and strengthens its expansion plans
TOYO, the Japan-headquartered solar solutions firm, will procure polysilicon from a US-based polysilicon manufacturer, locking in non-Foreign Entity of Concern (FEOC) supply for its modules. The manufacturer said it adds to the company’s existing non-FEOC overseas polysilicon supply to meet the growing demand for solar in the US.
The sales contract with the unidentified supplier for an undisclosed volume has a term of 1 year. It strengthens the company’s polysilicon supply chain for its solar module production in the US and TOYO’s cell manufacturing operations in Ethiopia (see TOYO Begins Production At 2 GW Solar Cell Factory In Ethiopia).
According to the Solar Energy Industries Association (SEIA), the US had more than 20 GW of operational polysilicon production capacity by December 2025, out of a total 33 GW announced. At present, Germany’s Wacker Chemie and US-based Hemlock Semiconductor are the only 2 companies actively producing polysilicon in the country.
Part of Corning Group, Hemlock was recently contracted by T1 Energy for polysilicon supply for its cell plant in the US (see T1 Energy Breaks Ground On 2.1 GW US TOPCon Cell Plant).
TOYO said its agreement aligns with US regulatory expectations and supports its strategic operational and market objectives.
“Partnering with a leading polysilicon supplier in the U.S., gives TOYO a strategic advantage in building a robust and policyaligned supply chain,” said CEO and Chairman of TOYO, Junsei Ryu. “This agreement strengthens our U.S. expansion by increasing access to domestic materials, positioning TOYO to deliver costeffective and sustainable solar solutions to the American market.”
TOYO launched the Ethiopian cell fab with 2 GW annual production capacity, expanding it by another 2 GW, citing robust external customer demand. It is feeding the company’s new Texas solar module factory with 2.5 GW targeted capacity, out of which 1 GW began commercial operations in October 2025.
TOYO expects its Houston fab to qualify for tax incentives under Section 45X of the Internal Revenue Code, which will bring up to $0.07/W in production credits through 2030.
In December 2025, TOYO acquired the remaining 24.99% membership interest in its US subsidiary TOYO Solar LLC.
