The global tin market is living with a missing pillar. Since August 2023, when authorities in Myanmar's semi-autonomous Wa State ordered a comprehensive resource audit and suspended all mining operations, the Man Maw mining complex — one of the world's largest tin producers — has sat largely idle (Source: Crux Investor, Oct 2025). What was initially expected to be a 3-to-6-month pause has stretched past 33 months, and no definitive restart date has been announced.
Before the shutdown, Myanmar supplied an estimated 30% of global tin concentrate, with the Wa State alone accounting for roughly 70% of Myanmar's tin output (Source: Crux Investor, Oct 2025; Reuters, Jul 2025). The ore from Man Maw is unusually high-grade — typically 3–5% tin content versus a global average of 0.5–1% — making the deposit economically critical even by remote mining standards (Source: Discovery Alert, Sep 2025).
The supply gap has become a defining feature of tin markets. LME three-month tin traded at $52,219 per metric tonne as of May 22, 2026, having surged from levels around $30,000–$37,000 in late 2025 (Source: Trading Economics, May 2026). The rally has been fueled by the compounding effect of multiple supply-side shocks: Indonesia's crackdown on illegal tin mining, which may remove up to 80% of Bangka-Belitung's output; persistent instability in the DRC's North Kivu province; and the prolonged absence of Myanmar's Man Maw (Source: Crux Investor, Oct 2025).
China — the primary destination for Myanmar's tin concentrate — has felt the squeeze most acutely. Monthly imports from Myanmar averaged roughly 15,000 tonnes through 2022 and 2023, when Man Maw was running at full capacity (Source: Reuters, Sep 2025). By July 2025, that figure had collapsed to just 933 tonnes — a 94% reduction. Chinese imports of tin raw materials from Myanmar recovered to 7,190 tonnes in November 2025, the highest monthly level since August 2024, but still far below pre-closure norms (Source: International Tin Association, Mar 2026).
The road back to production has been painstaking. In July 2025, the International Tin Association reported that several operators at Man Maw had secured three-year mining permits after elevated licensing fees had created a prolonged stumbling block (Source: Reuters, Jul 2025). On February 27, 2026, the Wa State Industrial and Mineral Resources Management Bureau formalized a cost-sharing mechanism for dewatering flooded mine shafts across 11 portals — a necessary engineering prerequisite before deeper, higher-grade adits can be accessed (Source: International Tin Association, Mar 2026). Industry participants estimate dewatering will take more than a month, and when combined with existing tax obligations, total cost burdens for mine owners approach 35% (Source: International Tin Association, Mar 2026).
Even if operations resume this year, production will likely ramp slowly. The International Tin Association projects that if domestic tin prices in China remain above RMB 350,000 per tonne through 2026, Myanmar's tin concentrate exports to China could approach 20,000 tonnes of contained tin for the full year — a meaningful improvement but still well short of the roughly 180,000 tonnes per year (annualized) that Myanmar shipped before the suspension (Source: International Tin Association, Mar 2026).
Against this supply backdrop, global refined tin demand runs at 360,000–380,000 tonnes per year, driven by electronics soldering, EV battery connectors, photovoltaic cell solder, and semiconductors (Source: Crux Investor, Oct 2025). Indonesia's refined tin exports fell to a multi-year low of 46,000 tonnes in 2024, with only a modest rebound to 53,000 tonnes expected in 2025 (Source: Crux Investor, Oct 2025). The supply-demand math is unforgiving: the structural deficit that formed during Man Maw's absence is not quickly reversible.
The broader market has entered speculative territory. Trading volumes on the Shanghai Futures Exchange tin contract exceeded 1 million tonnes on a single day in January 2026 — more than double the world's annual physical consumption (Source: IndexBox, Jan 2026). The China Nonferrous Metals Industry Association has warned parties to "avoid blindly following the trend," calling the rally "unreasonable" (Source: IndexBox, Jan 2026). Meanwhile, LME time-spreads have flipped into backwardation — the cash-to-three-month spread turning to a premium, signaling acute physical scarcity rather than mere speculative froth (Source: Crux Investor, Oct 2025).
The fundamental uncertainty remains the question of Wa State's intentions. The United Wa State Army, the heavily armed ethnic militia that controls the region, operates with near-total independence from Myanmar's central government. Its 2023 decision to suspend mining was justified as environmental and regulatory reform, but the opaque governance structure makes production timelines inherently unpredictable (Source: Reuters, Jul 2025; The Irrawaddy, Jul 2025). Funds appear to be betting that a return to pre-closure production levels is not imminent (Source: Reuters, Sep 2025).
For buyers and procurement teams, the Man Maw stalemate is not a short-term disruption — it is a structural feature of the tin market that has already persisted for nearly three years. With LME prices above $52,000/t and supply diversification options limited, the cost of the Wa State's resource audit is being paid by the entire global supply chain.
Procurement teams should assume Man Maw will not return to meaningful production before late 2026 at the earliest. The dewatering cost-sharing agreement is a positive signal, but restoration of pre-closure output — let alone growth — will be measured in quarters, not weeks. With Indonesian export restrictions compounding the gap and Chinese smelter demand absorbing whatever flows cross the border, the structural deficit in tin is likely to persist through at least H2 2026. Buyers should lock in term contracts where possible, evaluate secondary/recycled tin sources, and build inventory buffers against further supply-side shocks.
