Import duty guide

Import Duty from China to US: Practical Guide

Understand the pieces that can show up in a US import cost estimate: product-specific duty, China-specific tariff treatment, MPF, HMF, customs value, and broker fees.

Import duty is not one universal rate

Your duty rate depends on the product classification, origin, trade remedies, declared customs value, and current official rules. This guide helps structure the question. It does not classify your product or give a binding rate.

For China imports, also check whether Section 301 or another trade remedy applies to the specific HTS code.

Common import-cost components

Component Source boundary Limitation
Merchandise Processing Fee (formal entry) FY2026 MPF minimum and maximum for formal entries; rate included for calculator education. Does not determine whether a shipment qualifies for formal entry treatment.
Harbor Maintenance Fee (imports) HMF import fee rate for education and landed-cost estimation. May not apply to air, express, or non-vessel shipments.
User-entered duty and tariff rate Calculator input boundary: the site processes the user's chosen percentage but does not choose it. The site does not classify products.
Customs value basis Explains that U.S. duty is generally not assessed on CIF freight and insurance charges. Actual declared customs value can depend on transaction details.
Customs broker fee Volatile commercial service fee; should be entered from the user's own quote. Not an official fixed government fee.
