Tenaris, US Steel shares slide as South Korea escapes pipe-dumping duties

|About: Tenaris S.A. (TS)|By:, SA News Editor

Tenaris (TS) -5.5% premarket in a move attributed to reports that the U.S. decided not to impose anti-dumping tariffs on oil and natural gas pipe products from South Korea.

South Korea shipped 894K tons of tubular goods to the U.S. in 2013, but the Commerce Department did not levy anti-dumping duties on that country's producers because it ruled their prices weren't below what steel was being sold for in the American market.

US Steel (X), -3% premarket, says it is disappointed by Commerce's "failure to deal with important issues at this stage of the investigations."
