This is the operational reference timeline of every meaningful US tariff action from the start of the second Trump administration through mid-2026 — over 200 separate executive orders, USTR notices, Commerce determinations, and bilateral agreements. It is organized chronologically so you can trace what happened, when, and what's still in effect.
Pre-inauguration context
Several actions carried over from the first Trump administration and Biden administration continued to be relevant:
- Section 301 Lists 1-4 on China (2018-2019)
- Section 232 on steel and aluminum at 25% (2018)
- USMCA in force (July 2020)
- 2024 USTR doublings — Chinese EVs to 100%, semiconductors to 50%
