As answered by people managing GitHub and Import Cost Calculator.
Import Cost Calculator's answer:
You decide how far to take it: a quick duty number, the full landed cost, or a verdict on whether the order is worth placing.
Just want the duty? Enter product value and category and you get the estimated customs duty, estimated China-specific tariffs, and US customs fees, in one number with a breakdown.
Want the landed cost? Add shipping and quantity to see the total and the cost per unit.
Want to know if it's worth importing? Add your expected sale price for a GO / TIGHT / NO-GO verdict. Marketplace fee and ad spend start with editable defaults.
At any step you can refine the estimate with your own HS code rate, tariff settings and insurance cost. Free, no signup, and the page shows when the rates were last checked against CBP, USTR and the Federal Register.

Import Cost Calculator's answer:
Amazon FBA sellers, small D2C brands and first-time importers sourcing from China who want a realistic number before they commit to a supplier.
Also useful as a planning cross-check when comparing DDP quotes.
Import Cost Calculator's answer:
I kept seeing the same thing: the supplier quote looks fine, then duties, tariff layers and fees eat the margin.
I wanted a free tool that models the layers that apply to a China-to-USA order and just says GO, TIGHT or NO-GO on your numbers, so I built one.
