Jakarta, June 13, 2026 – Indonesia’s state-owned tin producer, PT Timah Tbk, is preparing to deepen its global footprint through a potential partnership with Yunnan Tin Co. Ltd, the world’s largest tin producer based in China.
The move signals Jakarta’s ambition to strengthen its bargaining power in the global tin market, while modernizing domestic mining operations with advanced technology.
A Meeting of Giants
PT Timah, part of the mining holding company MIND ID, accounts for roughly 13–15% of global tin supply, while Yunnan Tin controls nearly half of the world’s market.

Together, the two companies would represent an unprecedented concentration of market power, capable of influencing global tin prices and supply chains.
The cooperation, currently under discussion, focuses on technology transfer, joint exploration, and smelting efficiency.
PT Timah’s President Director, Restu Widiyantoro, emphasized that the partnership is not merely about profit but about learning from Yunnan Tin’s advanced practices in sustainable mining and processing.
Strategic Importance of Tin
Tin has become a critical mineral in the global economy.
It is essential for semiconductors, electronics soldering, and renewable energy technologies, making it a cornerstone of modern industry.
Indonesia, which contributed 22% of global mined tin in 2025, is positioning itself as a key supplier amid rising demand.
By aligning with Yunnan Tin, PT Timah hopes to secure a stronger role in shaping pricing mechanisms and ensuring supply stability.
Analysts suggest that such cooperation could give Indonesia leverage in negotiations with international buyers, particularly in Asia and Europe.
A joint bloc between PT Timah and Yunnan Tin could stabilize tin prices, benefiting producers but raising concerns among buyers about potential price manipulation.
PT Timah stands to benefit from Yunnan Tin’s expertise in closed-loop water systems and environmentally friendly smelting, improving efficiency and sustainability.
Closer ties with China in critical minerals may trigger scrutiny from Western markets, especially given tin’s role in electronics and defense supply chains.
Integrating Indonesian and Chinese mining practices will require careful coordination to avoid inefficiencies.
The partnership discussions are expected to gain momentum during Asia Tin Week 2026 in Kunming, China, where industry leaders will gather to address supply, demand, and sustainability challenges.
For Indonesia, the cooperation represents a chance to modernize its mining sector while asserting greater influence in global commodity markets.
If successful, the alliance could reshape the dynamics of the tin industry, positioning Indonesia not just as a supplier but as a strategic power broker in the global mineral economy.
