Cabot reports preliminary results of China carbon antidumpting duty order Cabot reported that the U.S. Department of Commerce has announced the preliminary results of its sixth annual administrative review of the antidumping duty order on imports of steam activated carbon from the People’s Republic of China. The preliminary margins are significantly higher than the previous rates for imports from Chinese producers of steam activated carbon entering the U.S. The preliminary margins calculated by the DOC range from $2.05/kg to $3.77/kg and apply to steam activated carbon that entered the U.S. between April 1, 2012 and March 31, 2013. Final antidumping margins in connection with this review are subject to change and vary depending on the manufacturer. The antidumping order went into effect on April 27, 2007, and was extended in early 2013 for an additional five years in connection with a sunset review proceeding. As a result, the order will remain in place until at least 2017, when a second sunset review proceeding will be undertaken.
