📌 Key Takeaways
- US aerospace manufacturers report worsening rare earth shortages despite a US–China trade truce.
- China remains dominant in rare earth processing and magnet production, controlling roughly 90% of global magnet output.
- Export controls and licensing delays continue to disrupt supply of key materials used in aerospace chips and defense systems.
US aerospace manufacturers are facing deepening rare earth shortages even after Washington and Beijing agreed to a trade truce, according to industry sources cited by Reuters.
The constraint centers on rare earth magnets, including neodymium-praseodymium (NdPr), critical for fighter jets, missile systems, satellites and semiconductor fabrication equipment.
In May 2025, US imports of Chinese rare earth magnets fell 93.3% after Beijing tightened export controls. Nearly a year later, companies say export licensing remains slow and approvals limited despite diplomatic efforts to stabilize trade. The implication is direct: supply chains critical to jets, missiles, satellites, and advanced chips remain exposed to Chinese leverage.
⛏️ Why Are Rare Earth Shortages Persisting?
China dominates the midstream of the rare earth supply chain. According to the US Geological Survey, China accounted for around 70% of global rare earth mine production and roughly 85–90% of processing and magnet manufacturing capacity in 2024.
Even when mined outside China, rare earth concentrates are often shipped back to China for separation and magnet fabrication. That structural dependence has not changed.
Reuters reports that US aerospace and semiconductor suppliers continue to face licensing delays and limited export approvals from Chinese authorities despite diplomatic efforts to stabilize trade. Several sources told Reuters that critical materials such as neodymium-praseodymium (NdPr) magnets — essential for high-performance motors and defense applications — remain constrained.

🛩️ What Does This Mean for US Aerospace and Defense?
Rare earth magnets are embedded in:
- F-35 fighter jet actuators
- Missile guidance systems
- Satellite components
- Advanced semiconductor fabrication tools
Defense systems are not price sensitive. They are availability sensitive.
If material flows stall, production schedules slip. For prime contractors and semiconductor equipment makers, that translates into working capital strain, delayed deliveries, and margin pressure.
The US defense sector is already in expansion mode. The Pentagon’s FY2025 budget request exceeded $850 billion, according to the US Department of Defense. Layer rare earth scarcity on top of that buildout, and the constraint becomes physical rather than financial.
The trade truce did not unwind China’s export control framework. It only paused escalation.
🤖 How Do Rare Earth Shortages Affect Semiconductor Supply Chains?
The aerospace bottleneck intersects with the semiconductor sector.
Rare earth elements are used in chipmaking equipment, high-performance motors, lasers, and polishing compounds. Semiconductor manufacturing is already capital intensive and geographically concentrated. Add rare earth friction, and resilience becomes harder to achieve.
Washington has pushed for domestic semiconductor manufacturing through the CHIPS Act, allocating $52 billion in subsidies. But building fabs does not solve upstream mineral dependency.
The US has rare earth resources. It lacks full-scale commercial separation and magnet manufacturing capacity at scale.
📈 Who Benefits?
Companies advancing rare earth separation, magnet production, or vertically integrated supply chains outside China move up the strategic value curve.
The US Department of Energy has already funded rare earth processing and magnet initiatives through its critical minerals programs. The Inflation Reduction Act and Defense Production Act authorities provide additional support mechanisms.
But scale takes time.
Mine development timelines can stretch 8–10 years. Processing plants require technical validation and customer qualification. Magnet manufacturing demands precision engineering.
In the interim, aerospace and defense supply chains remain exposed.
🫰 The Bigger Picture: Rare Earth Shortages as Policy Leverage
Rare earth shortages are no longer an abstract geopolitical risk. They are hitting aerospace chips and defense supply chains in real time.
That disconnect underscores the strategic reality: trade optics can improve faster than supply chains.
For investors and policymakers, the takeaway is clear. Rare earth shortages are not just about price volatility. They are about industrial capacity, national security, and leverage in a multipolar system.
The bottleneck is not demand. It is control.
