Decision Engine — Tool 02
Tariff Impact Calculator.
Section 122 is the operating tariff regime today — a flat 10% with USMCA-compliant goods exempted. It sunsets July 24 2026. This calculator surfaces the live rate, the MFN fallback, and the USMCA preference for any HTS code in nine manufacturing-relevant chapters.

Section 122 framework
Active Feb 20 2026 → July 24 2026
Per our Section 122 read — SCOTUS invalidated IEEPA tariffs Feb 20 2026; Section 122 is the statutory operating framework until sunset.

MFN baseline
No preferences applied — the legal-default fallback rate.
Section 122 — current In effect today
Active until July 24 2026. Flat 10% non-USMCA / 0% USMCA-compliant.
USMCA preference
USMCA-compliant + line carries USMCA preference. Best available rate.
Post July 24 2026 Unknown
Successor regime is unknown. Possible outcomes range from snap-back to MFN to a Section 122 extension to a new statutory framework. Track this honestly — do not anchor a multi-year decision to today’s rate.
What this v1 does not model
- Section 232 (steel + aluminum 25%) and Section 301 (China-specific 25–50%) — both add to MFN, they do not replace it
- Antidumping (AD) and countervailing (CVD) duties — applied on a country-and-producer basis
- USMCA Regional Value Content (RVC) math — the Yes/No toggle assumes compliance has been independently verified, it does not compute it
- Post-sunset successor regime — genuinely unknown today; the tool flags it rather than guessing
For an audit-grade landed-cost number, route the scenario through an Atlantis trade-compliance advisor.
Coverage and roadmap
v1 covers the manufacturing chapters that account for the bulk of Atlantis FDI scenarios. Other chapters and additional duty layers ship in v2.
Chapters in v1
39 plastics · 40 rubber · 73 iron and steel articles · 76 aluminum · 84 machinery · 85 electrical and electronic · 87 vehicles · 88 aerospace · 90 instruments and medical devices.
v2 — additional duty layers
Section 232 (steel and aluminum 25%) and Section 301 (China-specific 25–50%) layer on top of MFN — they do not replace it. Antidumping and countervailing duties apply on a country-and-producer basis. v2 surfaces the full stack for a given origin.
v3 — full HTS coverage
Lazy-loaded chapter chunks so the page stays light. v1 ships the chapters that cover ~80% of customer scenarios at a tractable bundle weight.
After July 24 2026
The post-sunset regime is genuinely unknown today. When something is signed into law, the calculator's "Post July 24 2026" row gets a real number. Until then it stays honestly TBD — anchoring multi-year decisions to today's rate is exactly the trap the tool is designed to surface.
