About Gateway Tariff Calculator
Calculate what your imports actually cost before you commit. Enter an HTS code and country of origin and get the duty owed, including every trade action that stacks on top of the base rate: Section 301, Section 232, Section 338, safeguards, AD/CVD and the rest, plus government fees and the landed total. You can also look up HTS classifications for a product, and see what changed in US trade policy and what takes effect next, each with its source. Figures come from the live US Harmonized Tariff Schedule and published trade actions, cited so you can check them. They are planning estimates, not customs rulings. Built and maintained by Gateway Lines, an FMC-licensed NVOCC and ocean freight forwarder, using the same tariff engine that prices our own shipments.
