The tin market's structural supply deficit is deepening. Myanmar's Wa State region has not resumed tin concentrate exports since the August 2024 mining suspension, removing an estimated 30,000t/year of concentrate from the global supply chain. The region previously supplied 70% of Chinese tin concentrate imports. Chinese smelters are now running at 65% of capacity due to concentrate shortages, down from 85% in 2024.

Indonesia's refined tin export quota system is further limiting supply. Shipments in 2026 are tracking 12% below 2025 levels through May, as the government continues to enforce minimum domestic processing requirements and export license restrictions. The PT Timah export allocation for H1 2026 was reduced by 8% compared to H2 2025.

The DRC's Bisie mine operated by Alphamin Resources, the world's third-largest tin mine, is facing logistics bottlenecks. Road and river transport constraints in the remote Kivu region have limited monthly output to 1,200-1,400t of tin-in-concentrate, below its technical capacity of 1,800t/month. Heavy rains have further disrupted the transport corridor.

On the demand side, the tin market benefits from secular growth in electronics and green energy. Solar panel manufacturing (tin coatings on copper ribbons) consumed an estimated 6,500t in 2025, with 10-15% annual growth expected. Electric vehicle battery soldering uses approximately 0.3-0.5kg of tin per vehicle, adding 500-800t/year of incremental demand as EV penetration grows.

What this means for buyers

Tin buyers face the most supply-constrained market among base metals. The structural deficit means any demand improvement translates directly into price increases. Secure minimum 3-month inventory coverage at current levels. For 2027 requirements, consider entering term contracts with price ceilings at $55,000-57,000/mt. The only realistic bearish catalyst is a Myanmar restart, which appears unlikely in 2026 given the political situation.
