On August 5, 2026, after communicating with major enterprises and filing with the National Development and Reform Commission, the Sulphuric Acid Association and the Phosphate and Compound Fertilizer Association jointly decided: to ensure fair and relatively stable prices, the "latest copper concentrate TCs" in the original guidance price formula was revised to the "average of the past three months' copper concentrate TCs". After careful consideration, the copper concentrate TCs used in the calculation are based on the SMM Copper Concentrate Index.
Calculated based on the new formula, the August smelting sulphuric acid guidance price is 1,555 yuan/mt. Historical guidance prices were May (1,406 yuan/mt), June (1,456 yuan/mt), and July (1,574 yuan/mt).
