Indonesia's tin policy mirrors its nickel strategy: the government is seeking to capture more downstream value by restricting raw material exports and encouraging domestic processing. This policy has reduced the volume of refined tin available for export, adding a structural supply constraint to an already tight market.
The electronics sector, which accounts for approximately 50% of global tin consumption through soldering applications, provides a powerful and growing demand base. Lead-free soldering regulations have locked in tin's essential role in electronics manufacturing, and the complexity of modern electronics — more chips, more connections, more solder joints per device — continues to increase tin intensity per unit of electronic output.
Semiconductor demand is surging, driven by artificial intelligence chip deployment, data center expansion, and 5G/6G telecommunications infrastructure. Each new generation of AI chips requires more advanced packaging with higher tin-containing solder content. Global chip sales have grown at double-digit rates through 2025-2026.
Solar photovoltaic manufacturing represents an emerging demand source. Each GW of solar panel capacity requires approximately 50-70 tonnes of tin for soldering interconnections. With global solar installations exceeding 500 GW annually, this represents a meaningful and growing consumption stream.
The combined effect of supply constraints (Myanmar shutdown, Indonesian restrictions) and steadily growing demand from electronics, solar, and industrial applications has created a structural deficit that BMI projects will persist through at least 2028.
Tin procurement requires a structural shift in expectations. The supply deficit is not cyclical but structural, driven by permanently reduced concentrate availability and steadily growing electronics demand. Buyers should secure long-term supply agreements and consider strategic inventory building. The $50,000/t level may represent a new floor rather than a temporary spike.
