Gallium is a soft, silvery metal that producers recover almost entirely as a byproduct of aluminum and zinc processing. It has emerged as one of the most geopolitically contested commodities of the decade. Gallium-based semiconductors power 5G networks, military radar systems, and satellite communications.
China produces 99 percent of the world’s primary gallium. The United States stopped domestic production almost four decades ago. That combination leaves gallium in a uniquely vulnerable position within the Western supply chain.
Beijing’s export controls, first imposed in 2023 and escalated to a full ban on US shipments in late 2024, have turned gallium from an obscure byproduct metal into a focal point of great power competition over critical minerals.
Background
Gallium is not mined directly. Producers recover it almost entirely as a byproduct of processing bauxite ore for aluminum. Smaller quantities are derived from zinc smelting residues.
This byproduct status shapes the entire gallium market. Production volumes rise and fall with aluminum and zinc economics, not with gallium demand. The supply chain cannot expand on its own when gallium prices climb.
Gallium gets its strategic value from its role in advanced semiconductors. Gallium arsenide (GaAs) and gallium nitride (GaN) compounds are essential to 5G infrastructure, high-frequency power amplifiers, and the RF components inside almost every smartphone.
Gallium also has applications in the defense industry: GaN-based components are used in advanced radar arrays, electronic warfare systems, missile seekers, and satellite solar cells. And this role is growing, with the GaN semiconductor device market alone projected to expand from $3.06 billion in 2024 to $12.47 billion by 2030, a compound annual growth rate of about 27 percent.
