HS Code Lookup Tool

Search by product description or keyword to find the correct Harmonized System code. Our AI classifier cross-references USITC rulings to ensure accuracy.

Why HS Code Accuracy Is Critical

Your HS code directly determines the duty rate applied to your imports. A single digit difference can mean paying 0% versus 25%. For a seller importing $500,000 of goods per year, a misclassification costing an extra 5% in duty translates to $25,000 in unnecessary expense. Worse, if you underclassify and get audited, you face back duties plus penalties that can exceed the original duty owed.

How to Use the HS Code Lookup Tool

Type a plain-language description of your product into the search field. Be specific about material composition, function, and intended use. For example, instead of searching for 'bag', try 'women leather handbag with textile lining'. The more detail you provide, the more precise the AI classification will be. Results show the recommended HS code, the duty rate, and a confidence score.

Common Classification Challenges

Multi-material products, sets and kits, and items with multiple functions are the most frequently misclassified. A product made of both plastic and metal must be classified based on the component that gives it its essential character. Sets must be classified as a whole rather than by individual components. Our AI handles these edge cases by applying the General Rules of Interpretation (GRI) used by customs authorities worldwide.

Frequently Asked Questions

What is an HS code?

A Harmonized System (HS) code is a standardized numerical classification used worldwide to identify traded products. The first 6 digits are internationally standardized, while the US adds 4 more digits for the full 10-digit HTS code. The code you assign to your product determines the tariff rate you pay at customs.

What happens if I use the wrong HS code?

Using the wrong HS code can result in overpaying duties, underpaying duties (which triggers penalties and interest if caught in an audit), shipment delays at customs, and potential seizure of goods. The penalties for intentional misclassification can reach up to 4 times the unpaid duty amount.

How does the AI classification work?

Our AI analyzes your product description against millions of USITC classification rulings and binding decisions. It considers material composition, function, and end use to suggest the most accurate HS code. The model is trained on actual customs rulings and is updated monthly with new decisions.

Is this tool free to use?

Yes. You can look up HS codes for individual products at no cost. For bulk classification of entire product catalogs, sign up for a free MarginHub account to upload a CSV or connect your e-commerce store directly.

How often are HS codes updated?

The World Customs Organization revises the international HS nomenclature every five years, with the most recent revision effective January 2027. The US HTS schedule is updated more frequently throughout the year. Our tool reflects the latest USITC published schedule within 48 hours of any change.
