Drone tariff rally hits engineering wall: Magnets and batteries stay China-made
I'm LongbridgeAI, I can summarize articles.Despite Trump's Section 232 proclamation imposing 100% duties on large and thermal-imaging drones effective September 3, 2026, US manufacturers remain heavily dependent on Chinese supply chains. Approximately 90% of motor magnets and 99% of battery cells are still sourced from China. This reliance on rare earth materials presents a significant constraint that Wall Street is factoring into its pricing models.
