[Domestic crucible enterprises plan to renegotiate long-term contracts with imported high-purity quartz sand enterprises] According to SMM, domestic PV crucible enterprises recently plan to renegotiate long-term contracts with imported high-purity quartz sand enterprises, mainly to lower the supply prices. The main reasons are the decline in planned production of silicon wafers and the suppression caused by the drop in silicon wafer prices. In addition, the reduction of some tariffs in the trade war has weakened the sentiment of tight supply. These comprehensive factors have led domestic crucible enterprises to plan to renegotiate long-term contract prices.
