U.S. Silicon Metal Producers Celebrate Positive Trade Rulings

In a significant development for the American silicon metal industry, Ferroglobe USA, Inc. and Mississippi Silicon LLC have expressed their satisfaction following recent preliminary trade rulings by the U.S. Department of Commerce. These rulings target unfairly priced and subsidized imports of silicon metal from companies in Angola, Australia, Laos, Norway, and Thailand. The impact of this ruling could be monumental, as silicon metal is essential for various manufacturing processes, including the production of aluminum, silicones, and even solar panels.

The favorable announcements made by the Department of Commerce are seen as crucial for maintaining a balanced and equitable market within the U.S. As silicon metal is associated with national security and clean energy initiatives, these determinations have broader implications for the industry and its workers. The fundamentals reflect a commitment to protecting domestic production which has been perceived as being jeopardized by these foreign imports.

On September 23, 2025, it was disclosed that preliminary countervailing duties would be imposed on silicon metal imports from Australia (41.31%), Laos (240.00%), Norway (16.87%), and Thailand (31.27%). Then, on September 26, additional duties were announced for imports from Angola (68.45%) and Laos (94.44%) regarding unfair pricing.

These duties signify a strong stance from the U.S. government to ensure that domestic producers have the opportunity to compete fairly against lower-cost foreign products. The effective date for these duties commenced shortly after their announcement, showing how quickly the administration is acting on these issues.

As stated by Marco Levi, CEO of Ferroglobe PLC, there is gratitude towards the diligent work being carried out by professionals at the U.S. Commerce Department. Levi emphasizes the importance of these decisions as they represent significant progress toward restoring fair competition in the market. He further expressed optimism for the upcoming final decisions expected in December, which will provide more clarity on the situation and its long-term implications.

Eddie Boardwine, CEO of Mississippi Silicon, echoed Levi's sentiments by stressing that fair competition is vital not just for the companies involved but for the employees and local communities that rely on the silicon industry. This action, he stated, helps secure the future of American manufacturing, providing assurance and stability for its workforce and customers alike.

Both Ferroglobe and Mississippi Silicon underscore their roles as key players in the silicon metal production landscape. Ferroglobe, a subsidiary of Ferroglobe PLC, is a leader in the industry, producing ferrosilicon and silicon metal in various manufacturing facilities across several states, including Ohio, West Virginia, South Carolina, and Indiana. Mississippi Silicon, a partnership between Rima Holding USA, Inc. and Clean Tech I LLC, produces silicon metal primarily for a wide range of industries—from aluminum and automotive to chemical processes—based out of Burnsville, Mississippi.

As we look ahead, additional rulings are anticipated. The Department of Commerce is expected to announce preliminary antidumping decisions for Australia and Norway on November 21, followed by final determinations for Angola, Laos, and Thailand on December 11, 2025. Each of these announcements could further transform how silicon metal is imported and priced in the United States.

In summary, the recent trade rulings provide a positive framework for U.S. silicon metal producers like Ferroglobe and Mississippi Silicon. They not only protect domestic manufacturers from unfair foreign competition but also strengthen the industry's future by ensuring a level playing field. This highlights a pivotal moment in U.S. trade policy that may shape the silicon metal market for years to come.
