What Yunnan Tin does

Yunnan Tin Co., Ltd. (云南锡业股份有限公司), listed on the Shenzhen Stock Exchange under ticker 000960 and headquartered in Kunming, Yunnan Province, is the world's largest tin producer since 2005, holding 25% of global and 50% of China tin market share. The company operates a vertically integrated non-ferrous metals business spanning four segments: mining (Datun Tin Mine, Kafang, Laochang, Hualian Zinc-Indium), smelting (Tin Branch, Copper Branch), deep processing (joint-venture materials companies), and supply chain distribution. Annual production capacities include 70,000 tons of tin, 125,000 tons of cathode copper, 100,000 tons of zinc ingots, 50,000 tons of cast zinc alloys, 60 tons of refined indium, plus gold, silver, and tungsten concentrate byproducts.

The company's technology portfolio centers on proprietary metallurgical processes including the world's first industrial application of hematite iron removal for zinc-iron separation (breaking a 42-year international monopoly), double top-blown copper smelting, and efficient vaporization technology for low-grade tin-bearing materials. These processes support cost-efficient processing of complex multi-metal ores and have earned multiple national and provincial science awards. The firm sells under standardized Chinese national specifications (GB/T, YS/T grades) across purity levels — Sn99.90, Sn99.99, Sn99.999 for tin; Zn99.995, Zn99.99 for zinc — to industrial customers globally, with pricing tied to SHFE tin futures benchmarks.

Revenue is generated primarily through direct hardware sales of metals to enterprise customers in electronics soldering (50% of global tin demand), semiconductor ITO manufacturing, renewable energy, galvanizing, and defense industries. Go-to-market combines sales-led direct engagement with a global supply chain segment and event-driven industry participation (notably the SMM Tin Industry Chain Conference). The June 2026 acquisition of Chifeng Dajingzi Tin Co., Ltd. and the 75.74%-owned subsidiary Yunnan Hualian Zinc-Indium reflect a consolidation strategy in tin and minor metals. Controlling shareholder Yunnan Tin Group (云锡集团) maintains strategic oversight. Profitability inflected sharply upward in 2025 with net profit +36.1% YoY, extending to +38-48% YoY in H1 2026 amid record tin prices.
