- China's rare earth export controls are crippling U.S. aerospace and semiconductor production.
- The price of critical yttrium has soared 69-fold in a year, halting some production lines.
- U.S. chipmakers face dangerous shortages of scandium, threatening 5G technology.
- Industry experts describe this as deliberate economic warfare by China.
- Long-term U.S. solutions are underway, but immediate shortages pose a severe threat.
While politicians tout trade truces, U.S. aerospace and semiconductor manufacturers are being slowly strangled by shortages of obscure minerals almost entirely controlled by China. The elements yttrium and scandium, unknown to most, are now at the heart of a high-stakes economic conflict that threatens to ground jets and halt the production of essential 5G chips.
This isn't an accident of the market; it's economic warfare. Despite an October detente between Washington and Beijing, Chinese exports of these critical rare earths to the United States remain a trickle. Chinese customs data reveals a telling story: in the eight months after China imposed export controls last April, only 17 tons of yttrium products reached the U.S., compared to 333 tons in the eight months prior.
The consequences are severe and already unfolding. The price of yttrium has skyrocketed, jumping 60% in recent months and now sitting at a staggering 69 times higher than it was just one year ago. This isn't just a number on a spreadsheet. Yttrium is vital for heat-resistant coatings that keep jet engines and turbines from melting. Without it, engines cannot function.
Production lines stalling
Industry insiders report that the shortage is forcing painful choices. Executives at two North American firms that use yttrium to produce these essential coatings told Reuters they have temporarily paused production. One company is now turning away smaller and offshore clients to conserve its dwindling supply for major engine manufacturers. Another firm in the supply chain has completely run out of material and stopped selling yttrium oxide products.
While full-scale engine production hasn't yet been impacted, the strain is undeniable. Aerospace supply chain specialist Kevin Michaels called the situation "a watch item and a tangible example of how China is flexing its rare earth muscle." Engine makers are already struggling to meet soaring demand from airlines and aircraft manufacturers, making this supply pinch a potential breaking point.
The pain extends from the skies to our smartphones. In the semiconductor sector, a parallel crisis is brewing over scandium, a metal for which the U.S. has zero domestic production. Dylan Patel, founder of research firm SemiAnalysis, warns that U.S. chipmakers are running low, putting next-generation 5G chips at risk.
"Major U.S. semiconductor manufacturers all rely on scandium for making chip components that go into essentially every 5G smartphone and base station," Patel said. He added that U.S. stockpiles are likely measured in months, not years.
A targeted strategy
Evidence suggests this is a deliberate squeeze. U.S. chipmakers are facing delays in receiving new scandium export licenses from China. One U.S. official, speaking on the condition of anonymity, stated, "Our thesis is that it is precisely the semi industry being targeted."
China requires license applicants to declare their end-users, giving Beijing precise control over who gets these materials and who does not. This move aligns with a broader strategy of using trade as a geopolitical lever, a tactic noted by analysts at the Center for Strategic and International Studies who highlighted "the centrality of rare-earth export restrictions" to Beijing's control.
The White House has stated its commitment to securing access to critical minerals, pointing to negotiations with China and efforts to build alternative supply chains. However, these are long-term projects. China refines more than 90% of the global rare earth supply, a dominance built over two decades after it flooded the market with cheap exports, undercutting and shuttering American processors.
This dependency is a glaring national vulnerability. The U.S. once processed its own rare earths, but the last domestic plant closed in the late 1990s. Now, with China wielding its near-monopoly as a weapon, American industry is held hostage. The recent trade talks and temporary agreements have done little to ease the immediate, choking pressure on factories and fabrication plants.
The message from Beijing is clear, even if unspoken. America's technological and military edge is built on minerals it does not control. As one coating manufacturer turns away customers and another halts sales, the abstract concept of "supply chain security" becomes a very real, very urgent problem on the factory floor. The truce hasn't ended the war; it has just moved the battlefield to a realm where America is dangerously unarmed. The race to rebuild what was lost is on, but for critical industries counting their stockpiles in months, time is the one resource already in short supply.
