Three years without Man Maw. Since August 2023, when the United Wa State Army (UWSA) imposed a comprehensive ban on all mining activity in northern Myanmar's Wa State, the global tin concentrate market has been living with a structural hole that producers, traders, and analysts have been unable to fill. China's smelting sector — historically the direct beneficiary of Wa State's tin ore — has borne the brunt of the disruption, with utilisation rates collapsing to approximately 60% of installed capacity, compared with pre-ban levels above 85%. (FACT: DiscoveryAlert, 2025; ITA, 2025)
Myanmar was the world's third-largest tin producer before the ban, with Wa State alone accounting for more than 70% of the country's tin output. According to USGS data, Myanmar holds approximately 700,000 tonnes of tin reserves — roughly 15% of global reserves, after China (800,000 tonnes) and Indonesia (720,000 tonnes). The Man Maw mine, the crown jewel of Wa State's tin production, was one of the largest single tin mines globally, supplying an estimated 30% of the world's tin concentrate before the shutdown.

The concentrate gap forced Chinese smelters into a scramble for alternative feedstock that has reshaped global tin trade flows. Australia and Nigeria both significantly expanded tin concentrate exports to China during 2025, according to trade data cited by DiscoveryAlert. Volumes from the Democratic Republic of Congo's Bisie mine — operated by Alphamin Resources, now backed by an Abu Dhabi sovereign wealth fund — also increased. But these alternative sources have been insufficient to offset the Myanmar shortfall, which is estimated at 30,000–40,000 tonnes of contained tin per year.

Attempts to restart the Man Maw mine have been mired in complexity. The International Tin Association announced in July 2025 that several operators had received three-year licences from the UWSA for a "controlled restart." However, by early 2026, BMI/Fitch Solutions noted that "there has been no further update yet," adopting a "wait and see approach" as "news of a resumption of tin mining at the Wa State have circulated markets for months without actually materialising." (FACT: BMI/Fitch Solutions, February 2026; The Hindu BusinessLine, February 2026)
The operational hurdles to restarting Man Maw are substantial. Industry analysis indicates that even if the UWSA issues full permits — a process described by observers as "notoriously opaque" — the mine would require 6–9 months of de-watering flooded workings and rehiring Chinese labour before meaningful production could resume. Underground mines that sat idle for three years require extensive rehabilitation of ventilation, pumping, and electrical systems. Optimistic scenarios project initial production sometime in late 2026 at the earliest; realistic assessments push meaningful output into 2027. (FACT: aInvest, 2025; DiscoveryAlert, 2025)
The reduced smelter throughput in China has cascading effects on the global refined tin balance. Chinese refined tin production fell noticeably in 2024 and remained constrained through 2025, even as domestic demand from the semiconductor and electronics sectors remained robust. The shortfall in Chinese refined output has contributed to the persistent backwardation in LME tin spreads and the drawdown of exchange inventories to near-historic lows before the January 2026 price rally. (FACT: LME, BMI/Fitch Solutions, ITA)
Some industry participants have suggested that the Myanmar crisis has permanently altered the structure of the tin concentrate market. Even if Man Maw restarts, the UWSA's willingness to shut down production for nearly three years demonstrates a level of sovereign control that will likely be reflected in higher royalty demands, tighter export controls, and less reliability for off-takers. The days of cheap, plentiful, and predictable Myanmar tin concentrate may not return regardless of the restart timeline. (FACT: MINING.COM, DiscoveryAlert, BMI/Fitch Solutions)
Chinese smelters have responded by investing in alternative supply chains. Several have secured offtake agreements with Australian and African producers, while others are exploring recycling and secondary tin recovery from electronic waste. But these measures are incremental: secondary tin currently accounts for roughly 20–25% of global refined output, and expanding that share requires significant investment in collection and processing infrastructure that will take years to materialise. (FACT: ITA, Expert Market Research, 2026)
Action: Assume Myanmar concentrate does not return in volume before 2027 at the earliest. Chinese smelter utilisation below 70% is now structural, not cyclical. European and Southeast Asian buyers who rely indirectly on Chinese refined tin should secure alternative supply arrangements now — the competition for non-Myanmar concentrate will only intensify.
Horizon: The first meaningful new mine supply outside Myanmar — the Taronga project in Australia, or expanded output from the DRC — is unlikely before 2028–2029.
Trigger: Any confirmed restart of Man Maw with a concrete timeline and tonnage estimates would be the strongest bearish signal for tin. Until that happens, the concentrate shortage underpins elevated prices.
