Gallium (symbol: Ga, atomic number: 31) is a soft, silvery metal and one of the most strategically significant materials in modern electronics. China produces over 80% of the world’s gallium and introduced export licensing controls in July 2023 — a move that exposed just how exposed Western defence and semiconductor supply chains are to a single-source chokepoint. Understanding what gallium is starts with understanding where it comes from and why Western governments are scrambling to secure it.
What Is Gallium and Where Does It Come From?
Gallium is not a rare earth element. It is a byproduct of aluminium production, recovered during the processing of bauxite ore. Primary gallium extraction is almost entirely dependent on aluminium refinery capacity — there is no significant standalone gallium mining industry. According to the USGS Mineral Resources Program, global refined gallium production is dominated by China, which accounts for more than 80% of annual output. The remainder comes from small-scale recovery operations in Russia, South Korea, Japan, and Ukraine.
The United States produces no primary gallium. This is not a recent development — US gallium production ceased decades ago as Chinese output, produced at lower cost alongside large-scale bauxite processing, made domestic recovery uneconomical.
What Is Gallium Used For?
The dominant application is semiconductor fabrication. Gallium arsenide (GaAs) and gallium nitride (GaN) are compound semiconductors with performance characteristics that silicon cannot match at high frequency and high power. GaAs is used in the radio frequency chips that power smartphones, satellite communications, and radar systems. GaN is the material of choice for 5G base station power amplifiers, military phased-array radar, and high-efficiency power electronics.
Beyond defence and telecoms, gallium compounds are used in LED lighting (gallium nitride-based LEDs underpin virtually all modern solid-state lighting), solar cells (gallium arsenide photovoltaics achieve the highest recorded conversion efficiencies), and medical imaging equipment. The defence applications are particularly sensitive — GaN-based radar and electronic warfare systems are embedded across NATO platforms.
China’s Export Controls: What Happened and Why It Matters
In July 2023, China’s Ministry of Commerce introduced export licensing requirements for gallium metal and gallium compounds. The measure required exporters to apply for permits on a shipment-by-shipment basis, with no transparency on approval timelines or criteria. Germanium controls followed in August 2023. For a detailed account of how these restrictions fit into the broader minerals trade dispute, see China’s rare earth and critical mineral export control strategy.
The immediate market effect was a sharp increase in ex-China prices as buyers sought to build inventory. Shanghai Metals Market (SMM) data from March 2026 puts the domestic China price at approximately $246/kg for 99.99% purity gallium, against an FOB China export price of around $400/kg — a spread that reflects both the licensing friction and accumulated Western buyer risk premium.
Western Supply Chain Response
No Western economy has yet established primary gallium production at commercial scale. Recovery from aluminium refinery streams is technically feasible but has not been developed due to capital cost and the historically low pre-2023 price. The EU explicitly lists gallium as a Strategic Raw Material under the Critical Raw Materials Act (CRMA), triggering requirements for member states to assess stockpile adequacy and diversify sourcing. The US Department of Defense has funded feasibility work on domestic gallium recovery, but no facility is in production as of early 2026.
Strategic stockpiling is underway across defence procurement agencies in the US, UK, and EU. Japan — which operates small-scale gallium recovery — has become a more significant secondary supplier. These measures reduce near-term vulnerability but do not resolve the structural supply gap.
Gallium Price and Market Outlook
The current gallium spot price reflects both Chinese production cost structures and the risk premium applied by Western industrial buyers since the 2023 controls. Price volatility is likely to persist while licensing uncertainty continues and no credible Western primary production capacity exists. Any escalation in the US-China trade relationship — particularly measures targeting semiconductor supply chains — would add further upward pressure.
Demand growth is structural. 5G network deployment, defence spending increases across NATO, and the continued buildout of high-efficiency power electronics all increase gallium consumption over the medium term. Supply responsiveness outside China is constrained by the byproduct dependency: gallium output tracks aluminium production, not gallium price.
What is gallium used for?
Gallium’s primary use is in compound semiconductors — gallium arsenide (GaAs) and gallium nitride (GaN) — which are used in 5G base stations, radar systems, satellite communications, LEDs, and high-efficiency solar cells. Defence applications include phased-array radar and electronic warfare systems. There is no significant substitute for gallium in these applications.
Why did China impose export controls on gallium?
China introduced export licensing requirements for gallium and gallium compounds in July 2023, citing national security and resource management grounds. The controls require exporters to obtain permits for each shipment, creating supply chain uncertainty for Western buyers. Most analysts view the move as a strategic response to Western semiconductor export restrictions targeting China’s chip industry.
How much gallium does China produce?
China accounts for over 80% of global refined gallium production, according to the USGS Mineral Resources Program. Production is concentrated in provinces with large aluminium refining capacity, particularly Henan and Guangdong. Russia, South Korea, Japan, and Ukraine produce the remainder, but none at a scale capable of substituting for Chinese supply.
What is the current gallium price?
As of March 2026, SMM data shows the domestic China gallium price at approximately $246/kg (99.99% purity), with the FOB China export price around $400/kg. Western market prices carry an additional risk premium. See the gallium price page for current benchmark data updated monthly.
Is gallium a rare earth element?
No. Gallium is not a rare earth element. Rare earth elements are the 17 lanthanide series metals plus scandium and yttrium. Gallium is a post-transition metal in Group 13 of the periodic table. However, it is classified as a critical mineral by the US, EU, UK, and other governments due to supply concentration risk and strategic end-use applications.
