South Korea is seeking an annual $350 million in trade sanctions against the United States in an Obama-era dispute over tariffs on steel pipes, it said in a World Trade Organization (WTO) filing published on Tuesday. South Korea went to the WTO in 2014 to challenge U.S. tariffs levied on oil country tubular goods (OCTG), a type of steel piping used in the energy industry. Washington said its tariffs aimed to stop South Korea exporting the product at unfairly cheap prices.
