As China continues its rare earth export control measures, the U.S. aerospace and semiconductor industries are facing an increasingly severe shortage of rare earth supplies.

This situation may trigger a chain reaction affecting key enterprises such as Boeing, GE Aerospace, Honeywell, and Raytheon Technologies, which rely on rare earth materials to produce high-performance components. Rare earth elements play an irreplaceable role in the manufacturing of high-tech products such as jet engines, missile guidance systems, and chip substrates. Supply chain experts point out that if the shortage continues to worsen, it may impact the production stability of the U.S. defense and cutting-edge technology sectors. At present, some companies have already initiated emergency plans and are seeking diversified supply channels, but it is difficult to completely replace China's dominant position in the short term.
