China’s Ministry of Commerce (Mofcom) says in a statement on its website that it will also begin anti-dumping investigations into polysilicon made in South Korea.

The move had been widely expected after South Korea’s ambassador to China revealed earlier this week he had received notification from Mofcom that it was starting preliminary research on Korea’s polysilicon exports to China.

Mofcom says it received an application on 2 July from four companies – Jiangsu Zhongneng Polysilicon, LDK Solar, Luoyang-based Sino-Silicon and Daqo New Energy – requesting an anti-dumping investigation into US and South Korean polysilicon imports, and a countervailing duty investigation on imports from the United States.
