HTS heading 8460 is a broad product category for machine tools that finish metal or cermets—hard, ceramic-like materials used in some cutting tools—by removing or smoothing material with grinding stones, abrasives, or polishing products. It can include machines used for deburring, sharpening, grinding, honing, lapping, polishing, and similar finishing operations. It does not cover the gear cutting, gear grinding, or gear finishing machines assigned to heading 8461.
To reach the correct 8-digit HTSUS code, first identify the machine’s principal finishing function and how it operates. The subdivisions under heading 8460 commonly distinguish among machine types and, in some cases, the material or workpiece being processed, such as metal versus cermet. Review the complete 8-digit descriptions and any applicable legal notes, definitions, and statistical suffix information; do not choose a code based only on a product name or marketing description. If the machine has multiple functions, classification may require customs-broker or other professional analysis of its principal function and design.
What to check
- Confirm that the machine works on metal or cermets and uses grinding stones, abrasives, or polishing products.
- Describe the principal operation precisely: deburring, sharpening, grinding, honing, lapping, polishing, or another finishing process.
- Check whether the machine is specifically for gear cutting, gear grinding, or gear finishing, which may place it outside heading 8460.
- Compare the machine’s workpiece material, tool type, automation, and operating method with every applicable 8-digit subheading description.
- Use the manufacturer’s technical literature, model specifications, drawings, and intended use to verify the classification; seek a binding ruling or customs-broker advice when the distinctions are unclear.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
