AD/CVD

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.

Background on AD/CVD Investigations

Antidumping duty (“AD”) and countervailing duty (“CVD”) investigations are brought jointly by the U.S. International Trade Commission (“USITC”) and the U.S. Department of Commerce (“Commerce”). AD investigations are triggered when a domestic industry alleges that it has been injured by competing imports of particular goods from specific countries being sold at less than a fair value. Meanwhile, CVD investigations are triggered when a domestic industry alleges that it has been injured by competing imports that are being unfairly subsidized by their governments. The domestic industry initiating the investigation is known as the petitioner while the foreign industry participating in the investigation is known as the respondent.

Scope of the Investigation

The merchandise covered is 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.
