Section 122 — 10% global baseline
The 10% across-the-board baseline that replaced the invalidated IEEPA 'reciprocal' tariffs after the 2026-02-20 Supreme Court ruling. Temporary (Section 122 caps duration at ~150 days and rate at 15%). USMCA and Section-232-covered goods may be excluded — this is the single most time-sensitive line in the dataset; always re-verify.
