The United States imports substantial quantities of optical, medical instruments from Taiwan, with approximately $114B in total bilateral trade.

This 10% rate has a built-in expiration: Section 122 limits presidential tariff authority to 150 days, meaning the tariff expires approximately July 24, 2026 without congressional renewal.
