Free HTS Code Lookup Tool

What Is an HTS Code, and Why Does It Matter?

An HTS (Harmonized Tariff Schedule) code is a 10-digit number the US uses to classify every product entering the country. It determines your duty rate, whether the shipment needs a license, and how customs treats it on arrival. Get the code wrong, and you risk overpaying duties, customs delays, or even penalties for misclassification.

Common Mistakes New Exporters Make

• Classifying by the marketing name of a product instead of its material composition and function
• Using a competitor's or supplier's HTS code without verifying it applies to your specific product
• Missing special trade program rates (like USMCA) that could lower the duty owed
• Not re-checking codes when a tariff schedule update changes classifications

From Lookup to Paperwork, Automatically

This free tool searches the same USITC database our documentation portal uses. The difference: inside the portal, once you find a code, it's saved to your product library and auto-populates onto your commercial invoices, shipper's letters of instruction, and certificates of origin — no retyping, no version mismatches across documents.
