On April 24, 2025, Ferroglobe USA, Inc. and Mississippi Silicon LLC (collectively, “Petitioners”) filed an antidumping and countervailing duties petition on ferrosilicon from Angola, Australia, Laos, Norway, and Thailand.

Antidumping duty investigations are administered by the U.S. Department of Commerce (DOC) and the U.S. International Trade Commission (“ITC”). Dumping occurs when a foreign company sells a product to the United States below its normal value or cost of production. Subsidy is defined by a foreign government providing financial assistance to a foreign company for manufacturing or exportation.

The scope of the petition (subject to change during the investigation) covers:

******************************************************************************

All forms and sizes of silicon metal, including silicon metal powder. Silicon metal contains at least 85.00 percent but less than 99.99 percent silicon, and less than 4.00 percent iron, by actual weight. Semiconductor grade silicon (merchandise containing at least 99.99 percent silicon by actual weight and classifiable under Harmonized Tariff Schedule of the United States (HTSUS) subheading 2804.61.0000) is excluded from the scope of this investigation.

Silicon metal is currently classifiable under subheadings 2804.69.1000 and 2804.69.5000 of the HTSUS. While the HTSUS numbers are provided for convenience and customs purposes, the written description of the scope remains dispositive.
