• Mexico & Canada are pinned; use More to add other countries (multi-select).
• The left column shows each country’s Country rate. The §122 pill is the current surcharge baseline (post-Feb 24, 2026). At earlier dates the blue R pill shows the historical IEEPA reciprocal rate.
• The sector cards (Autos, Steel, Aluminum, Copper, etc.) are Section 232 measures — unchanged by the regime shift.
• Click any card or the §122/R pill to see “Why this rate?”, open Source (White House/CBP), or Copy details.
• Rates shown are headline ad-valorem percentages. §122 surcharge exempt categories include USMCA goods, §232 articles, energy, critical minerals, pharma, certain ag, electronics, vehicles/parts, aerospace, CAFTA-DR textiles.
• Current order of precedence (post-Feb 24, 2026): 1) Section 232 — Autos (exempt from surcharge) 2) Section 232 — Steel, Aluminum, Copper, Timber, MHDVs (exempt from surcharge) 3) §122 — 10% universal surcharge (150 days, USMCA exempt) 4) §301 — China duties (stack with surcharge).

This tool is for quick reference only and does not constitute legal or customs advice. Obligations depend on product-specific HTS classification, origin (e.g., USMCA/T-MEC), exemptions, and current agency guidance. IEEPA tariff authority was invalidated by the Supreme Court on Feb 20, 2026; all IEEPA ad valorem duties ended Feb 24, 2026. The new §122 surcharge (10%, 150 days) expires ~Jul 24, 2026 unless Congress extends. Section 232 and Section 301 measures remain unchanged. Always verify current status in CSMS/Federal Register before relying on this view.
