The smelting cost of zinc is mainly composed of raw and auxiliary materials, fuel power, labor, manufacturing and other expenses. The change of zinc concentrate price, fuel and electricity price will have obvious influence on zinc smelting cost.

2. Changes in the use of refined zinc

3. Import and export tariffs

Import and export policy, especially tariff policy, is an important means to balance domestic supply and demand by adjusting the import and export cost and controlling the import and export volume of commodities. The reduction of tax rebate will increase the cost of zinc, thus pushing up the price of zinc. In June 2003, the export tax rebate rate of zinc and zinc alloys decreased from 65,438+05% to 65,438+065,438+0%, and further decreased to 8% in May 2005. From June to 10 in 2006, the export tax rebate rate of zinc all decreased to 5%.

4. Inventory

In addition to the above key factors, changes in the macroeconomic situation and the relationship between supply and demand will also have an impact on zinc prices.
