Gateway Tariff Calculator

US import duty and HTS codes

Category: Operations
Primary Subcategory: Freight & Logistics Operations

Integration details

Description

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.

Tools

3 tools agents can invoke

Calculate US import duty and landed cost. Give hts_code when you know it and this returns the base duty, every additional trade action that applies (Section 301, Section 232, Section 338, AD/CVD and others), the total duty owed, government fees and the landed cost. Give product instead and it returns candidate HTS codes WITHOUT pricing, because the classification decides the duty and guessing it produces confidently wrong numbers: confirm the right code with the user, then call again with hts_code. The candidate step is not charged.
landed_cost
Find the US Harmonized Tariff Schedule classification for a product. Returns candidate HTS codes with their official descriptions and base duty rates. Use when the user wants the code itself rather than a cost.
classify_hts
List US trade policy changes Gateway has published since a given date: new tariff actions, rate changes, effective dates and expirations. Use to answer "what changed recently" or "what is coming".
policy_changes_since
