Yunnan Tin makes bid for takeover of Chifeng Dajingzi
Yunnan Tin, the world’s largest producer of refined tin, has announced its intention to bid for fellow Chinese tin smelter Chifeng Dajingzi Tin Industry Company, a subsidiary of state-owned China Nonferrous Metal Mining Group (CNMC).
The bid is a part of an auction for 100% equity of the Inner Mongolia-based company, which has a production capacity of 5,000 tonnes per year, and this move appears to be linked to Yunnan Tin’s aim of building a ‘northern tin hub’ in China.
Inner Mongolia province is home to two large tin mines – Baiyinchagan and Huanggangliang – and saw mine production of 11,000 tonnes tin-in-concentrate in 2025, or 15% of China’s total tin mine production.
The reserve price is RMB 177 million (approximately US$26 million). It is uncertain what the final transaction price will be, or if Yunnan Tin will be successful in its bid.
Chifeng Dajingzi saw revenue of RMB 699 million (approximately US$103 million) in 2025, with a net loss of RMB 67 million (approximately US$10 million).
Given the extreme, prolonged tightness in the concentrate market, consolidation of China’s smaller tin smelters is not unexpected. As long as Myanmar’s output remains weak, smaller smelters will continue to struggle to compete with larger, vertically-integrated producers.
