Ferroglobe has petitioned the U.S. ITC to investigate exports of silicon metal from four countries to the U.S., which it alleges were dumped at margins of up to 135%. The ITC has 45 days (April 24) to make a preliminary decision, though the support of unions and alleged loss of jobs may draw the administration more closely into the fray. Panjiva data shows U.S. imports actually fell 27% in the fourth quarter of 2016 on a year earlier, while imports from the four countries accused increased 8%. It’s not just American producers that have lost out.
