the production capacity planned by China's polysilicon industry is large, enterprises are still generally faced with technical problems. A large number of production lines are in the trial phase, or due to high production costs, there is no actual production. In 2011, the total import volume of polysilicon in China was 64,614 tons, with an increase of 36% YOY; the import amount was USD 3.814 billion, with an increase of 42.1% YOY. This means that China's import demand for polysilicon is still great.
