Why India imports it. No 300mm wafer manufacturing in India; only 150mm pilot lines at MEPL and SITAC.
Why it matters. Wafers are the substrate for every chip; without local supply, India's fab ambitions are built on a single fragile import.
Can India localise it? Partial - requires polysilicon + crystal growth capex, 5-7 year horizon.
Where it comes from. Japan (60%), South Korea (25%), Germany (15%).
