Cabot Corp. Reports Preliminary Results of U.S. Department of Commerce Review of Antidumping Order on Steam Activated Carbon from China

Cabot Corporation (NYSE: CBT) reported that the U.S. Department of Commerce (DOC) 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 United States.

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 United States 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.

“We are pleased with the preliminary margins announced by the Commerce Department,” said Friedrich von Gottberg, president, Cabot Purification Solutions Segment. “We continue to believe that the anti-dumping order is helping to level the playing field in the U.S. activated carbon market. Our Cabot Norit Activated Carbon team will continue to provide our customers with high-quality products and an unmatched level of supply assurance from our North American manufacturing facilities.”

Cabot’s North American activated carbon manufacturing facilities are located in Pryor, Okla., Marshall, Texas, and Bienfait, Saskatchewan.

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.
