US Targets 'Unfair' Silicon Metal Dumps from Four Countries
Published Date: 5/21/2025
Notice
Summary
The U.S. Department of Commerce is starting investigations to see if silicon metal from Angola, Australia, Laos, and Norway is being sold unfairly cheap in the U.S. This affects companies importing silicon metal from these countries and could lead to new duties (extra taxes) to protect U.S. producers. The process kicked off in May 2025, so importers should watch for possible cost changes soon.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 2 costs, 1 mixed.
Importers Face Potential New Duties
The Department of Commerce initiated antidumping (LTFV) investigations on silicon metal from Angola, Australia, Laos, and Norway on May 14, 2025. If the investigations lead to antidumping duties, importers of silicon metal from these countries could face higher costs or cash-deposit requirements as the cases proceed.
Very Large Estimated Dumping Margins
The petitions include estimated dumping margins used for initiation: Australia 328.89%, Norway 102.08%; under market-economy methodology Angola 68.45% and Laos 94.44%; under non-market-economy methodology Angola 207.28% and Laos 231.63%. These estimates indicate the scale of alleged underpricing Commerce is investigating.
U.S. Producers Filed Petitions Seeking Protection
Ferroglobe USA, Inc. and Mississippi Silicon LLC filed the antidumping petitions on April 24, 2025, and Commerce found they represent the domestic industry (100% of U.S. production identified in the petitions). The investigations could lead to relief (duties) that would protect U.S. silicon metal producers if Commerce and the ITC find dumping and injury.
Investigation Timelines and Evidence Period
The period of investigation (POI) is April 1, 2024 through March 31, 2025. Commerce will make preliminary determinations no later than 140 days after these initiations, and the U.S. International Trade Commission will preliminarily determine injury within 45 days after the petitions were filed (the petitions were filed April 24, 2025).
