SMM Survey: China Zinc Smelters See Higher Raw Material Inventory Days as Ore Supplies Loosen

On September 9, 2026, Australia initiated its second sunset review of anti-dumping measures on galvanized steel sheet from India, Malaysia and Vietnam, and separately launched a sunset review of countervailing measures on imports from India. The review covers July 2025-June 2026, with the final report expected by February 11, 2027. As galvanized steel is the largest end-use sector for zinc, the measures directly affect export costs and competitiveness, potentially impacting Australia’s domestic zinc demand and supply chain. Maintaining the duties would provide some protection for domestic steel and coating capacity, while termination could increase low-priced imports and affect regional zinc consumption. The final outcome remains subject to the authorities’ determination.

Market offers from ore traders remained limited this week, while winter stocking demand persisted. Some Chinese smelters continued to inquire about and procure imported concentrates for Q4, with market treatment charges remaining at low levels.

According to SMM, a zinc mine in Northwest China offered a September self-pickup tender price of around -RMB 2,800/metal tonne this week. SMM will continue to monitor changes in treatment charges.
