China Germanium Prices Hit Record High as Demand Destruction Emerges

Germanium

China germanium prices have reached record highs, but the rally is beginning to destroy demand across key downstream markets. Buyers in infrared optics and bismuth germanate crystals are reducing purchases, drawing down inventories or switching to alternative materials.

China germanium prices for 99.999% metal reached 18,000-24,500 yuan/kg on 16 June, the highest level since market assessments began in 2011. Prices have risen by around 84% since early January.

China germanium prices remain supported by tight feedstock availability, restricted spot sales and investment demand. However, rapidly weakening consumption is creating a growing disconnect between physical end-user demand and market pricing.

The emerging substitution trend is particularly important because sustained high prices could permanently reduce germanium intensity in civilian applications.

Infrared Buyers Shift Toward Alternative Materials

Infrared optics have been among the sectors most affected by the price surge. Some producers have sharply reduced or completely stopped germanium purchases because current prices make conventional applications uneconomic.

One infrared producer that previously consumed 8-9t/yr has not purchased germanium since last year, with its infrared business now largely inactive.

Some civilian applications are replacing germanium wafers with chalcogenide glass. This substitution reduces exposure to germanium prices while allowing manufacturers to continue serving less demanding optical markets.

Export controls are adding further pressure. China's tighter dual-use licensing requirements have reduced exports of germanium-containing infrared products and weakened demand from manufacturers dependent on overseas customers.

Bismuth germanate crystal producers are responding similarly. Some buyers are relying entirely on existing inventories and evaluating replacement materials rather than purchasing germanium at current prices.

The medical imaging sector consumes around 10t/yr of germanium for bismuth germanate crystals, making prolonged substitution potentially significant for total market demand.

Once customers redesign products around alternative materials, some of that demand may not return even if germanium prices later decline.

Tight Feedstock and Export Controls Keep Prices Elevated

Despite weaker consumption, supply conditions remain tight enough to support China germanium prices.

Germanium is primarily recovered as a byproduct from zinc and lead processing, meaning supply cannot easily respond to higher prices. Producers cannot simply increase germanium output without corresponding feedstock availability.

Major suppliers are also committed to long-term contracts, leaving limited metal available on the spot market. Some producers and traders have raised offers to 25,000-26,000 yuan/kg for small volumes without completing transactions.

Financial activity is adding another layer of support. Germanium contracts introduced on the Zhonglianjin trading platform in May have attracted investment interest, strengthening bullish sentiment even as industrial demand weakens.

Export availability has tightened further. China exported only 1,825kg of wrought germanium metal and fabricated products during January-April, less than half the 4,287kg shipped during the same period of 2025.

Lengthy permit procedures and tighter inspections have made producers increasingly reluctant to commit material to overseas customers.

The market is therefore caught between severe supply constraints and emerging demand destruction. Prices may remain elevated in the near term, but substitution and declining exports could eventually limit further gains.

The Metalnomist Commentary

Germanium is demonstrating the limit of strategic scarcity: prices can rise until customers redesign products to avoid the metal entirely. If substitution spreads beyond civilian infrared applications, today's supply squeeze could permanently reshape the demand base.
