About StackTariff

StackTariff helps small and mid-sized importers answer one question fast: what is the total, current tariff on this exact product — and what will it cost to land?

The post-2024 US tariff regime stacks several measures on top of the base rate — Section 301 (China), Section 232 (steel & aluminum), IEEPA and reciprocal tariffs, plus AD/CVD orders and customs fees — each with its own effective dates and exclusions. Tools built before 2024 get this stacking wrong. We compute it from live government data and show you the date every rate is current as of.

What we are — and aren’t

We’re an informational tool. We are not a customs broker: we don’t file entries, accept Power of Attorney, or communicate with CBP on your behalf. Classification and valuation remain the importer’s responsibility under 19 USC §1484. When an entry needs filing, we point you to a licensed customs broker.
