What this site is
A set of planning calculators and reference material for people who import goods and buy advertising. Free to use, for commercial purposes included, without an account.
What these numbers are not
Not customs advice. Duty applies per 10-digit HTS code. Our figures are category-level approximations built from a representative code, and the range within a category can be very wide. Your customs broker’s classification determines what you actually owe. Where our model is known to be imprecise, we say so on the result itself and in more detail on the methodology page.
Not financial, tax or legal advice. These are arithmetic tools. What you do with the output is a business decision and it is yours.
Not a guarantee of accuracy. Tariff rates and platform fees change, sometimes with little notice — three separate tariff regimes applied to US imports during 2026. We verify against primary sources and date every figure, but a rate can change between our check and your use of it.
Liability
The site is provided as is. We are not liable for losses arising from decisions made using these estimates. If a figure looks wrong, tell us — we would rather fix it than defend it.
Acceptable use
Use the calculators as much as you like. Do not scrape the site at a rate that degrades it for others, and do not republish our tariff tables as though they were your own research. Linking to a page and quoting a figure with attribution is welcome and needs no permission.
Paid plans
Pro is not open for sign-ups yet. When it opens: monthly billing, no minimum term, cancel any time with access until the paid period ends. Your data exports as CSV whether you are paying or not.
