The Gallium Gamble_ Navigating China's Control

China's overwhelming control of the global gallium supply—over 98%—leaves the United States entirely dependent on imports, exposing its semiconductor industry to supply shocks and geopolitical leverage. The episode details how August 2023 export restrictions from China disrupted chains, drove prices up sharply, and prompted U.S. efforts to diversify sources amid rising tensions.

China's Gallium Dominance

China produces nearly all the world's gallium, a byproduct primarily from aluminum smelting. Between 2000 and 2022, it dramatically increased aluminum output, which in turn solidified its gallium production lead. This positions China to influence global markets strategically. The U.S. sources its gallium imports mainly from China, Canada, Germany, and Japan, with no domestic production of low-purity gallium, making it acutely vulnerable to any supply interruptions.

Export Restrictions and Market Shock

In August 2023, China imposed stringent export rules on gallium, far beyond minor tweaks. These caused immediate supply chain disruptions worldwide. By March 2026, prices had surged to $2,100 per kilogram—a 123% increase since early 2025. The restrictions appear calculated to exploit China's dominance, potentially reshaping supply chains and geopolitical dynamics. This event underscores how such controls can destabilize industries reliant on consistent access.
