U.S. Silicon Metal Producers Welcome Duties on Unfairly Traded Silicon Metal Imports From Bosnia and Herzegovina and Iceland

​

MIAMI, Dec. 9, 2020 (GLOBAL NEWSWIRE) – Globe Specialty Metals, Inc. (“GSM”), a subsidiary of Ferroglobe PLC (NASDAQ: GSM), and Mississippi Silicon LLC (“MS”), together representing the majority of American silicon metal production, welcomed news on December 8^th that the U.S. Department of Commerce ("Commerce") will impose preliminary duties of up to 47.54% on all silicon metal imports from Iceland and Bosnia and Herzegovina.

​

This announcement is the latest development in ongoing investigations of unfairly-traded silicon metal imports from Bosnia and Herzegovina, Iceland, Malaysia and Kazakhstan and closely follows an announcement that Commerce will impose preliminary duties up to 120% on all silicon metal import from Kazakhstan.  In August, the U.S. International Trade Commission (“ITC”) preliminarily determined that imports from all four countries are a cause of material injury to the U.S. industry.

​

“The fact that suppliers in Bosnia and Herzegovina and Iceland have distorted the market has made it difficult for us to compete,” said Marco Levi, Chief Executive Officer of GSM’s parent, Ferroglobe. “Like the duties recently imposed on imports from Kazakhstan, these duties will level the playing field and help restore real, honest competition. We appreciate the diligent efforts by the Commerce Department to see that the trade rules are followed.”

​

“The Commerce Department’s actions to address unfairly-traded imports from Bosnia and Herzegovina and Iceland come as good news to our business, our workers, and our entire industry,” said Eddie Boardwine, Chief Operations Officer of MS. “We greatly appreciate the government’s efforts to stop unfair trade practices and look forward to seeing conditions in the U.S. market reflect free and fair trade of silicon metal.”

​

On June 30, 2020, GSM and MS filed petitions to stop silicon metal producers in Bosnia and Herzegovina, Iceland, Malaysia and Kazakhstan from selling dumped and unfairly subsidized silicon metal imports into the United States. In their petitions, the companies asked the Commerce and ITC to impose duties on to offset unfair pricing and unfair subsidies.

​

Following this announcement, preliminary determinations will be announced in the Malaysia investigation on January 27, 2021.  

​

Silicon metal is an important element added to various grades of aluminum alloys used in performance applications such as automotive components and aerospace products. Silicon metal also is a critical raw material in the production of silicone compounds used in numerous products including sealants, adhesives, rubber gaskets, caulking compounds, lubricants, food additives, coatings, polishes, and cosmetics, among others. In addition, silicon metal is the base material in the production of polysilicon, a purified form of silicon used in solar cells and semi-conductors.
