US import duties on electronics & semiconductors · 2026
France hosts STMicroelectronics' most advanced 300mm wafer fab in Crolles, producing leading-edge process nodes for STM32 microcontrollers, MEMS sensors, and RF chips. Soitec in Bernin is the world's leading producer of silicon-on-insulator (SOI) wafers — a substrate used in advanced automotive and RF chips. Lynred in Grenoble produces cooled and uncooled infrared detector arrays for defense and industrial imaging. French-origin electronics face only the 10% Section 122 surcharge — no Section 301.
