Indium's market dynamics are shaped by one fundamental constraint: it is a by-product of zinc smelting, meaning its supply cannot respond to demand signals. Roughly 70% of global refined indium comes from China, with South Korea and Japan accounting for most of the remainder. Global refinery production stood at approximately 990 tonnes in 2023, with projections of 2,470 tonnes by 2025 and 3,420 tonnes by 2030, driven by capacity additions in South Korea and China.
Demand is dominated by ITO. Indium-tin oxide (ITO) for transparent conductive coatings on LCD displays, touchscreens, and OLEDs consumes 70-80% of global indium supply. The display market is mature in volume terms — global display area growth is 2-3% annually — but each generation of displays uses comparable indium loading per unit area, creating a steady baseline of roughly 1,200-1,400 tonnes annually. Emerging applications in microLED displays could add another 200-300 tonnes of demand by 2028.
CIGS solar adds the growth story. Copper-indium-gallium-selenide (CIGS) thin-film PV modules consume roughly 20-50 mg per W of indium. Global CIGS capacity is approximately 5 GW and growing at 10-15% annually, driven by building-integrated PV (BIPV) and lightweight module applications. Each GW of CIGS adds roughly 30-60 tonnes of indium demand. By 2028, CIGS could consume 250-400 tonnes annually — a material share of the market.
China's export controls. Indium was included in China's expanded critical mineral export controls in 2024, though the restrictions are less severe than those applied to gallium and germanium. Export licensing requirements have increased administrative friction and reduced spot availability. China exported 347 tonnes of indium in the first 9 months of 2024, down from pre-control baselines. South Korea absorbed 74% of these exports.
Price outlook. Indium prices have risen from approximately $250/kg pre-control to the current $560-660/kg range. The tight supply-demand balance suggests prices will consolidate at $550-700/kg through 2026, with upside toward $800/kg if CIGS solar deployment accelerates beyond current projections.

Indium buyers should watch two variables: zinc smelter throughput (which controls supply) and CIGS solar deployment (which drives incremental demand). We recommend term contracts with Korean refiners (Korea Zinc, Young Poong) as the most reliable non-Chinese source. The 2026 budget range is $550-800/kg. For ITO procurement, evaluate target utilization improvements that reduce indium consumption per display without sacrificing optical performance.
