U.S. to Ban Chinese Rare Earths From Defense Systems by 2027, Forcing Chip Supply Chain Overhaul
The U.S. will ban Chinese-origin rare earth materials from defense systems by 2027, fracturing global semiconductor supply chains and accelerating domestic sourcing mandates. ASIC design costs have nearly doubled since FinFET adoption, and lithography masks at advanced nodes cost tens of millions of dollars — making any supply disruption acutely expensive for chip makers. Domestic producers and foundry partnerships are racing to fill the gap before the deadline closes qualification windows.
