China Probes U.S., South Korea Solar-Grade Polysilicon
China is investigating whether exporters from the U.S. and South Korea sold solar-grade polysilicon below cost, a practice known as dumping, as part of a probe following complaints from four domestic companies.
The world’s biggest supplier of solar panels also started a countervailing duty investigation into the commodity from the U.S., China’s Ministry of Commerce said in two separate statements.
The actions escalate a trade dispute between the world’s biggest economies after the U.S. said in May it will impose duties on Chinese solar cells, which are devices made from polysilicon and assembled into panels that convert sunlight into electricity.
China will examine a tax-exemption program for the “advanced-energy manufacturing industry” promoted by the U.S. federal government and 15 state-government sponsored programs in Michigan, Tennessee, Washington and Idaho, the ministry’s statement on the countervailing duty investigation said.
