About HTSKit
HTSKit is a free toolkit for importers, freight forwarders, and trade compliance professionals. We make it easy to look up HTS codes, calculate import duties, and estimate shipping costs — without navigating the 4,000-page Harmonized Tariff Schedule yourself.
Our data is sourced from the United States International Trade Commission (USITC) and updated regularly to reflect current tariff rates, including Section 301 modifications.
What We Offer
- HS Code Lookup — Search by product name to find the correct 6-digit HS code and 10-digit HTS code with applicable duty rates.
- Duty Calculator — Enter an HS code to get MFN duty rates for both US and EU imports.
- Shipping Estimator — Reference freight rates by route and mode (sea, air, express) for China-origin shipments.
Data Sources
All tariff data comes from the official USITC Harmonized Tariff Schedule. EU rates are sourced from the TARIC database. Shipping rates are compiled from publicly available carrier rate cards and industry benchmarks. While we strive for accuracy, always verify rates with your customs broker for binding rulings.
