Gallium spot prices surged to $580 per kilogram this week, a 40% increase over the 30-day trailing average, after China's Ministry of Commerce confirmed that export permit requirements for gallium — introduced as a national security measure in August 2023 — will be extended indefinitely with tightened approval criteria. China controls approximately 80% of global refined gallium production, making it the dominant supplier to semiconductor and defense electronics manufacturers worldwide.
The announcement sent gallium prices to their highest level since the initial export control announcement three years ago. Before the 2023 restrictions, gallium traded at roughly $220 per kilogram. The current price of $580 represents a 163% increase from that baseline, reflecting the structural supply constraint created by China's export licensing regime.
Gallium is a byproduct of aluminum refining, produced from the Bayer process liquor that extracts alumina from bauxite ore. Its primary end-use is gallium arsenide (GaAs) and gallium nitride (GaN) semiconductors used in high-frequency electronics, radar systems, 5G base stations, and satellite communications hardware. The U.S. Department of Defense has classified it as a critical material, and it appears on both the EU and U.S. critical minerals lists.
Outside China, gallium production capacity is extremely limited. Germany produces small quantities as a byproduct of zinc refining at Norsk Hydro's Neuss facility, and Kazakhstan has modest output. The United States has no primary gallium production — a strategic gap that Congress has sought to address through the CHIPS and Science Act, which allocated funding for domestic critical mineral processing but has yet to bring new supply online.
The semiconductor industry's exposure to gallium constraints is particularly acute in defense applications. GaN-based power amplifiers are essential components in AESA radar arrays, electronic warfare systems, and missile guidance systems. Lockheed Martin, Raytheon, and Northrop Grumman have all flagged gallium supply security as a risk factor in recent quarterly filings.
Commercial buyers are responding by seeking alternative supply chains and accelerating R&D into gallium-reduced device architectures. Silicon carbide (SiC) and silicon germanium (SiGe) technologies offer partial substitution in some applications, but both have performance trade-offs at high frequencies that limit their use in the most demanding defense applications.
Investors with exposure to the critical minerals space should note that gallium's price trajectory depends heavily on diplomatic and trade policy outcomes. A negotiated resolution to U.S.-China technology trade tensions could rapidly normalize supply and compress prices. In the absence of such resolution, however, the structural deficit is likely to persist as Western governments slowly build alternative supply chains — a process that typically takes five to ten years from exploration to production scale.
