Classify any product, calculate the real import duty
Four free, no-login customs tools built on PortRobin's cited HTS dataset: an HS code finder, an import duty calculator, a full landed cost calculator, and an $800 de-minimis checker.
HS Code Finder
Describe any product and get its most likely US HTS code, ranked, with the classification reasoning and the real duty rate.
Import Duty Calculator
Enter an HS code and origin for the base US rate plus Section 301, 232 and 2025–26 tariffs, and the estimated duty.
Landed Cost Calculator
Add freight, insurance, MPF and HMF for the all-in delivered cost of your import, itemised line by line.
$800 De Minimis Checker
See whether a low-value shipment is under $800 and eligible to enter duty-free — including the 2025 China/HK suspension.
