The United States Is Repeating Its Silicon Mistake with Gallium Nitride

As of April 2026, the United States faces a critical supply chain vulnerability in gallium nitride (GaN) semiconductors due to China’s near-total control of global gallium production and its December 2024 export ban to the U.S., a move that exposed zero domestic stockpiles and threatens advancements in defense systems, 5G infrastructure, and electric vehicle power electronics—repeating the strategic missteps seen during the offshoring of silicon chip manufacturing in the 1990s and 2000s.

The problem is not merely technical; We see systemic. When China halted gallium shipments in late 2024, it did more than disrupt a commodity flow—it revealed how decades of prioritizing low-cost overseas manufacturing eroded America’s ability to secure foundational materials for next-generation chips. Unlike silicon, which the U.S. Once dominated before ceding fabrication to Taiwan and South Korea, gallium has no meaningful domestic mining or refining capacity. The U.S. Geological Survey confirms that as of 2025, the United States produces less than 1% of the world’s gallium, relying entirely on imports, primarily from China, which refines over 99% of global supply.

This dependency became acute when the Biden administration’s CHIPS Act of 2022 began funneling $52 billion into domestic semiconductor fabrication—yet overlooked upstream material security. By early 2025, defense contractors like Raytheon and Northrop Grumman reported delays in GaN-based radar systems for the Joint All-Domain Command and Control (JADC2) initiative, while Tesla and Ford warned of potential slowdowns in EV inverter production due to uncertain GaN wafer supplies. The irony is stark: the exceptionally technologies meant to ensure military and economic competitiveness are now hostage to a single foreign supplier.

How a Forgotten Mineral Became a Linchpin of 21st Century Power

Gallium nitride’s advantages over silicon are well-documented in engineering circles: higher electron mobility, superior thermal conductivity, and the ability to operate at higher voltages and frequencies. These traits make GaN indispensable for high-efficiency power converters in data centers, 5G base stations, and electric powertrains. A 2024 study by the Institute of Electrical and Electronics Engineers (IEEE) estimated that GaN adoption could reduce global energy waste in power conversion by up to 25%—equivalent to avoiding 1.2 gigatons of CO₂ annually by 2030.

Yet the U.S. Overlooked this vulnerability despite clear warning signs. In 2018, the Department of Defense listed gallium as a strategic and critical material in its Industrial Base Analysis. By 2020, the Pentagon’s Defense Logistics Agency warned that reliance on Chinese gallium posed “a high-risk vulnerability” to missile guidance systems and satellite communications. Still, no federal stockpile was established. When China imposed export controls in 2023—initially targeting specific grades—and then a full ban in December 2024, the National Defense Stockpile had nothing to release.

“We treated gallium like an afterthought,” said Dr. Elena Vasquez, a materials science professor at Arizona State University who advises the Semiconductor Industry Association. “We invested billions in fabs but ignored the mine-to-wafer pipeline. Now we’re paying the price in delayed programs and inflated costs.”

“The gallium shortage isn’t just a supply chain hiccup—it’s a strategic wake-up call. If One can’t secure the raw materials for chips we design, we don’t truly control our technological future.”

Geo-Local Impacts: From Phoenix Foundries to Pittsburgh Policy

The ripple effects are already visible in specific U.S. Regions. In Phoenix, Arizona—home to Intel’s Ocotillo campus and a growing cluster of GaN startups like Transphorm and GaN Systems—local manufacturers report a 40% increase in raw material lead times since early 2025. The City of Phoenix’s Office of Economic Development has begun convening monthly roundtables with semiconductor suppliers to assess risks to the Southwest’s burgeoning “Silicon Desert” corridor, which now includes over 12,000 jobs tied to compound semiconductor R&D.

Meanwhile, in western Pennsylvania, the legacy of steel is giving way to a new industrial ambition. The Pittsburgh-based Advanced Robotics for Manufacturing (ARM) Institute has partnered with Carnegie Mellon University to develop recycled gallium recovery processes from end-of-life electronics—a potential domestic secondary source. Allegheny County officials have earmarked $3 million in state grants for pilot projects that could reclaim up to 15% of regional gallium demand by 2028 through urban mining initiatives.

“We’re not waiting for federal action,” said Maria Gonzalez, Director of Sustainable Manufacturing at the ARM Institute. “If the feds won’t build a stockpile, we’ll create a circular economy model right here in the Rust Belt—turning waste into security.”

“Local innovation can fill gaps that national policy overlooks. Urban recovery of critical minerals isn’t just environmentally sound—it’s a matter of industrial resilience.”

The Directory Bridge: Who Solves This?

This crisis demands more than policy speeches—it requires action from specialized entities capable of rebuilding domestic resilience. Companies engaged in critical mineral recycling and urban mining are emerging as key players, particularly in states with strong electronics recovery laws like California and New York. Meanwhile, international trade and supply chain attorneys are advising manufacturers on navigating export control compliance and sourcing alternatives under the Export Administration Regulations (EAR).

Equally vital are industrial engineering consultants who can redesign supply chains for redundancy—identifying vetted secondary suppliers in jurisdictions like Japan, Germany, or Canada, where gallium refining capacity exists but remains underutilized due to market dynamics. These professionals don’t just react to crises; they help organizations anticipate them.

Editorial Kicker

The United States did not lose its edge in silicon since it lacked ingenuity—it lost focus on the foundations. Gallium nitride offers a second chance to get it right: to treat materials security not as an afterthought of innovation, but as its prerequisite. If we fail to act now, we won’t just be buying chips from abroad—we’ll be buying dependence. And in an age where technological sovereignty defines national security, that is a mistake we cannot afford to repeat.
