NEW YORK — Imports of diamond sawblades and parts from China and South Korea from Nov. 1, 2010, to Oct. 23, 2011, were sold at below normal value, the Commerce Department’s International Trade Administration (ITA) has determined in a preliminary anti-dumping duty administrative review. It issued dumping margins ranging from zero to 164.09 percent for Chinese producers/exporters and zero to 121.19 percent for Korean shippers.

The Diamond Sawblades Manufacturers’ Coalition has alleged that Chinese and South Korean producers sold diamond sawblades in the United States bearing a false country of origin, an allegation that Commerce is still investigating.
