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