On January 20, 2014, the Ministry of Commerce of China decided to impose countervailing duties on imported solar-grade polysilicon originating in the United States and anti-dumping duties on imported solar-grade polysilicon originating in the United States and South Korea from that day, with the implementation period of 5 years.
Among them, the countervailing duty rate of American companies is 0-2.1% , and the anti-dumping duty rate is 53.3% -57% ; The anti-dumping duty rate of Korean companies is 2.4%-48.7% . On November 21,

review ruling shows that if anti-dumping and countervailing measures are terminated, subsidies for imported solar-grade polysilicon originating in the United States may continue or recur, and dumping of imported solar-grade polysilicon originating in the United States and South Korea against China may continue or recur. The damage to China's solar-grade polysilicon industry is likely to continue or recur.
