This is a market dataset, representing the consumption market of the region. The dataset includes transport from the gate to the point of consumption, and transport services are calculated based on the transport situation of this product in the region. Solar-grade high-purity polysilicon is made from metallurgical-grade silicon, with a purity of over 99.9999% after purification, and is used in the photovoltaic industry; if you cannot determine the preparation process of high-purity polysilicon, you can use this dataset; this dataset is a weighted average of the datasets for \"high-purity polysilicon, improved Siemens method, solar grade\" and \"high-purity polysilicon, silane fluidized bed method, solar grade\". For specific technical details, scope boundaries, and other information, refer to the production datasets of high-purity polysilicon for each process.
