AUSTIN, Texas and NEW YORK, July 28, 2025 - T1 Energy Inc. $(TE)$ has announced its support for the U.S. Secretary of Commerce's decision to initiate a Section 232 investigation under the Trade Expansion Act of 1962. This investigation will examine the use of foreign-sourced polysilicon and its derivatives. T1 Energy, which holds a contract for American-made hyper-pure polysilicon, anticipates gaining a competitive edge from any potential tariffs or import restrictions resulting from the investigation. The company also plans to back tariffs under the Solar 4 anti-dumping and countervailing duty case concerning imports from Indonesia, Laos, and India. This aligns with T1 Energy's strategy to establish a domestic solar supply chain, including their operational G1_Dallas solar module facility and the planned G2_Austin solar cell facility. T1 believes these regulatory actions will bolster U.S. energy security and promote domestic manufacturing.
