Our commitment to quality is one of GCL Silicon's defining characteristics. Our quality control consists of three components: incoming inspection, through which we ensure the quality of the raw materials that we source from third parties, in-process quality control of our manufacturing processes and output quality control of finished products through inspection and testing.

In order to facilitate our production of polysilicon and ensure both the quality and quantity of the finished products, we have set up a laboratory responsible for the analysis of raw material in-process quality control and finished products and the supervision of environmental pollution and safety.
