Indium Holds Near Decade-High Prices as China Export Curbs Meet a $125 Million US Stockpile Order

What happened

Refined indium has held near $500 to $600 per kilogram in the Rotterdam physical market through 2026, its highest sustained level since early 2015, after climbing more than 55% since September 2025 -- a range Reuters first reported in February and again confirmed as recently as July. China supplied about 70% of the world's roughly 1,080 tonnes of refined indium output in 2024, and its unwrought indium exports fell more than 23% month-on-month to just 22.72 metric tons in December, tightening availability outside the country. Argus senior analyst Cristina Belda said the tight supply of crude indium is "a long-standing structural issue, exacerbated by China's increasingly stringent environmental protection policies." The squeeze has drawn a strategic response from Washington: the US Defense Logistics Agency published a solicitation in January for up to $125 million of high-purity (4N, 99.99%) indium ingots, split across two three-year supply contracts awarded to Indium Corporation and AIM Products LLC. South Korea, led by top producer Korea Zinc, supplies roughly 17% of global output.

The details

Indium's price chart tells a story that's become familiar across several minor metals this year: a market too small and too geographically concentrated to absorb even a modest supply tightening without a sharp, lasting price response. Refined indium climbed more than 55% between September 2025 and February 2026 to reach $500-600 per kilogram in Rotterdam, its highest sustained level since early 2015 -- and rather than fading, Reuters found the same range still holding as recently as July. That persistence is the real story: this isn't a one-day spike that reverses on profit-taking, it's a price floor that has held for the better part of a year, even though the current level still sits well below the $750-800/kg speculative peak of 2010, a reminder that this market has swung this hard before and eventually cooled.

The mechanism behind the current move starts with a structural fact about indium that doesn't change year to year: it's almost never mined on its own. Indium is recovered as a byproduct of zinc refining, which means primary supply is capped by how much zinc gets processed, not by how much indium producers might want to produce at a higher price. China controls roughly 70% of the roughly 1,080 tonnes the world refines annually, and when Chinese environmental policy tightens -- Argus analyst Cristina Belda points to increasingly stringent environmental rules as the driver -- that supply doesn't simply relocate to another producer; it just shrinks. December's more-than-23% month-on-month drop in China's unwrought indium exports, to 22.72 metric tons, is the export-side evidence of exactly that dynamic playing out.

What makes this more than a routine commodity squeeze is the buyer that just showed up. The US Defense Logistics Agency's January solicitation for up to $125 million in high-purity indium ingots -- structured as two long-term, three-year supply contracts with Indium Corporation and AIM Products LLC -- is a stockpiling program, not a spot purchase. Defense stockpiling demand doesn't respond to price the way commercial buyers do; the DLA's mandate is supply security, not cost minimization, which means this demand is likely to persist through a price cycle that would normally cause commercial buyers to substitute or defer purchases. Indium's listing as a strategic material under both the European Union's Critical Raw Materials Act and US critical-minerals initiatives reflects the same logic driving the DLA's order: governments increasingly treat a metal's supply concentration, not just its price, as the risk that needs managing.

On the demand side, indium's largest industrial application, indium tin oxide (ITO), remains the transparent conductive coating behind touchscreens, flat-panel displays and certain thin-film solar cells -- demand that tends to track consumer electronics and renewable-energy manufacturing cycles rather than swing wildly on its own. With South Korea's Korea Zinc, the world's top indium producer at roughly 17% of global supply, sitting outside the Chinese export-control perimeter, non-Chinese refiners are positioned to capture a growing share of buyers looking to diversify. That's the setup Julia Khandoshko of Mind Money was describing when she called indium "a critical raw material whose consumption is only increasing and supply is not keeping pace" -- a genuinely structural mismatch, not a speculative spike alone, even if speculative buying has amplified the move at the margins.

Why it matters

India's own electronics and display manufacturing ambitions -- from the government's semiconductor and display-fab push to expanding solar-panel production -- depend on the same indium tin oxide supply chain now facing decade-high prices and a China-concentrated chokepoint. A metal most Indian manufacturers rarely think about directly becomes a real input-cost and supply-security question the moment a country tries to scale domestic display or touchscreen assembly, exactly the kind of critical-mineral dependency India has been working to map and diversify across lithium, rare earths and now, increasingly, minor metals like indium.
