China import duties — Chapter 73: Articles of iron or steel
Total stacked US import duty as a % of customs value for articles of iron or steel (HTS Chapter 73) imported from China, snapshot as of 2026-06-18. From China, expect the base duty plus Section 301 (if the code is listed), IEEPA and the reciprocal baseline — and Section 232 on metals. This is the heaviest-stacking origin.
