Tin Supply Risks Resurface, MSC Poised to Capture Price Upside

Tin supply disruptions in Indonesia, DRC and Myanmar tighten global markets, lifting prices. MSC remains insulated through rising in-house ore, strong demand and improved earnings visibility.

Global tin markets are once again grappling with supply-side uncertainty, as disruptions across key producing regions tighten availability and push prices structurally higher. Indonesia’s recent crackdown on around 1,000 illegal mines in Sumatra has revived concerns over refined tin exports, a critical issue given the country’s status as the world’s largest refined tin exporter.

Rising Risks

These pressures are compounded by elevated risks at the Bisie mine in the Democratic Republic of the Congo, which contributes roughly 8% of global tin ore supply. Persistent security challenges and restrictions on manual mining continue to constrain output.

Meanwhile, Myanmar’s tin ore production remains hampered by adverse weather, labour shortages and equipment bottlenecks. This limits the pace of supply normalisation despite sizeable reserves estimated at about 700 kilotonnes, or 15% of global reserves.

Against this backdrop, Malaysia Smelting Corporation (MSC) stands out as relatively insulated from global supply disruptions. The company is supported by rising in-house ore contributions from its Rahman Hydraulic Tin (RHT) operations, where output is targeted to ramp up to 15 metric tonnes per day by 4QFY26F following improvements in sand-tailings recovery.

Additional resilience comes from previously secured Tasmanian feedstock. Conservative assumptions remain in place, with RHT production modelled flat at around 14 metric tonnes per day in FY26F, positioning MSC to benefit from tighter supply through higher prices rather than volume risk.

On the demand side, refined tin consumption remains firmly anchored by the electronics industry, which accounts for about half of global demand.

Semiconductor packaging, printed circuit boards and the shift toward lead-free solder continue to drive structural growth. With global semiconductor sales expanding strongly and further growth forecast into FY27F, refined tin demand visibility remains solid. As supply constraints persist, tin prices are expected to stay elevated, supporting MSC’s earnings outlook and valuation upside.
