Executive summary. China controls 98% of the graphitization process required to convert raw graphite into battery-grade anode material — the highest processing concentration across all critical minerals. The US effective tariff on Chinese graphite anode material now stands at approximately 220%. IEA projects graphite demand will grow 20-25 times by 2040. Non-Chinese graphite projects in development cover 25-30% of projected demand. There are no substitutes for graphite in lithium-ion battery anodes. FACT ESTIMATE
