US Faces Growing Shortage of Critical Rare Earths Despite Trade Truce with China

• February 26, 2026

US suppliers serving the aerospace, semiconductor, and defense sectors are experiencing intensifying shortages of vital rare earth elements, notably yttrium and scandium. These elements are crucial for advanced technologies and nearly exclusively sourced from China, which continues to dominate global production despite recent trade agreements aimed at easing tensions.

Persistent Supply Constraints in Key Industries

Yttrium and scandium are integral to manufacturing processes in cutting-edge defense systems, aerospace engineering, and semiconductor fabrication. However, disruptions in supply chains and limited alternative sources have pushed prices sharply upward. Yttrium in particular has seen an unprecedented spike over the past year, underscoring the fragility of the US rare earth supply infrastructure.

Even following a temporary truce in trade relations between the US and China, challenges remain unresolved. The US continues to rely heavily on imports from China, which mines and processes the vast majority of these rare earth metals. This dependence leaves the US vulnerable to potential supply manipulation or export restrictions that could impact national security and technological leadership.

Industry experts warn that without significant investment in domestic mining, processing capabilities, and diversification of supply sources, the shortage of critical rare earths like yttrium and scandium will persist. This could have far-reaching effects on manufacturing timelines, costs, and the ability to produce advanced electronics and defense equipment.

Efforts are underway to identify and develop new rare earth deposits within the US and allied countries, alongside recycling initiatives to reclaim these elements from existing products. However, such projects face long timelines and regulatory hurdles before they can mitigate current supply risks effectively.

As demand for high-performance materials escalates amid technological advancements in aerospace, defense, and semiconductor industries, securing a stable supply of rare earth elements remains a strategic priority for the US. Addressing this challenge involves balancing international trade policies, fostering domestic resource development, and encouraging innovation in material science.

The current situation highlights the ongoing complexities of global supply chains for critical materials and the need for sustained attention to reduce vulnerabilities in strategic sectors.
