Know the real tariff on any product — in seconds.
The 2025–26 tariff regime stacks Section 301, 232, IEEPA and reciprocal duties on top of the base rate — and most calculators still get it wrong. StackTariff computes the current total on your exact SKU, with effective dates.

Stack the duty
See the full pile: base MFN + Section 301 + Section 232 + IEEPA + reciprocal + AD/CVD + MPF/HMF — each with its effective date. This is what other tools get wrong.
Landed cost → broker
Add freight and insurance for your true landed cost, then hand the entry to a licensed customs broker when you’re ready to clear it.

Built for the regime that exists now
Section 301 lists expanded repeatedly, Section 232 rates rose, IEEPA introduced a whole new tariff class, and the $800 de-minimis exemption ended. Rates change weekly — so the engine reads them from live government feeds (USITC, CBP CSMS, the Federal Register) and stamps every result with the date it’s current as of.
