US ferroalloys market participants have expressed surprise at a decision by domestic ferrosilicon producers Globe Specialty Metals and CC Metals and Alloys to file an appeal challenging July's negative final dumping determination by the Department of Commerce on ferrosilicon imports from Russia.

On August 29, the two companies filed an appeal with the US Court of International Trade in New York. The appeal is against the US government as defendants and Globe and CC Metals and Alloys as plaintiffs.

"They just don't give up, do they?" said one trader. "It's not like they're not making money at current ferrosilicon prices. Given they've already stated they'd rather be making silicon, I don't understand it."

The trader was making reference to comments made by Globe CEO Jeff Bradley on August 26 that the company was considering switching a furnace from producing standard-grade ferrosilicon to silicon metal because of higher margins in silicon.
