Rare Earth Shortages Worsen in US Aerospace and Chip Industries Despite Trade Truce
Suppliers to the United States aerospace and semiconductor sectors are grappling with escalating shortages of rare earth elements, even as a recent trade detente between Washington and Beijing aimed to ease tensions on critical mineral exports. The shortfall, centred on niche but indispensable elements such as yttrium and scandium, is straining supply chains that underpin advanced jet engines, defence technologies, and next-generation chips.
Yttrium, pivotal in high-temperature coatings that keep turbine engines and aircraft components operational under extreme heat, has seen a dramatic supply squeeze. Although China relaxed some export restrictions after placing controls last year, shipments to the United States remain scant, with customs data showing a sharp drop in yttrium exports compared with pre-restriction levels.
Industry insiders report that several North American suppliers have been forced to pause production or ration deliveries, prioritising larger clients over smaller customers as stocks dwindle. Prices for yttrium products have surged sharply since late 2025, reflecting the severity of the shortage.
Scandium, another rare earth with a limited global output, is also in short supply. It plays a key role in specialty alloys and advanced semiconductor processing, particularly for 5G technology components. With no operational domestic production in the US and export licensing delays reported by chipmakers seeking supplies from China, shortages threaten timelines for critical technology development.
The supply crunch comes as the US government and industry stakeholders prepare for upcoming diplomatic talks between President Donald Trump and Chinese President Xi Jinping, where access to critical minerals is expected to feature prominently. Washington is pursuing negotiations with Beijing while exploring alternative sources and encouraging the development of domestic and allied rare earth capacities.
Despite the trade truce and diplomatic engagement, the rare earth shortfall highlights ongoing strategic vulnerabilities in key industrial supply chains and underscores the challenges facing US manufacturers reliant on imports for essential advanced materials.
