⚠️ Strategic Insight

China controls 80-90% at multiple chokepoints — rare earth magnets, battery cells, and final assembly. Western reshoring efforts (MP Materials, VAC, the NDAA 2027 ban on Chinese-origin magnets in defense procurement) are racing to diversify but remain 5-10 years behind in scale.
