Tariff Stack Visualizer

Enter a US HTS code and country of origin. See the actual duty stack — General + §232 + §301 + §122 + AD/CVD — with primary-source citations to the Federal Register, USTR, and CBP. The same engine that powers TariffDesk's alerts.

How the stack is built: Each surcharge stacks additively on top of the base general rate. §232 applies to metals (Chapters 72-76) and an enumerated derivative-articles list (Proclamation 11021 + USTR Annex). §301 List 1/2/3/4A/4B + four-year-review additive rates apply to China-origin imports. §122 is the 10% reciprocal baseline that sunsets on 7/24/2026.
