HS Code for CNC cutter grinder

CNC cutter grinders are classified under HS code 8460.31. This classification is designated for machine tools used for sharpening, tool, or cutter grinding that are numerically controlled. The Harmonized System distinguishes between machines that remove metal to shape a part (like lathes or mills) and those that finish or sharpen existing tools. Since a cutter grinder's primary function is the maintenance or precision finishing of cutting edges on tools like end mills, drills, and hobs, it is placed under heading 8460. The "numerically controlled" specification ensures it is categorized under the .31 subheading rather than the .39 subheading for manual machines. These machines utilize abrasive wheels to remove minute amounts of material to achieve extreme sharpness and specific tool geometries. The CNC capability allows for the complex multi-axis movements required to grind helical flutes and relief angles on modern industrial cutting tools. This classification applies regardless of whether the machine is used for manufacturing new tools or re-sharpening used ones, provided the process is abrasive grinding.

Common Misclassification

A common error is classifying these under 8460.12 or 8460.22. Code 8460.12 is reserved for flat-surface grinding machines, while 8460.22 is for cylindrical grinding machines. While a cutter grinder may perform cylindrical movements, its specific purpose for "tool or cutter" sharpening takes precedence under the specific provision of 8460.31.

FAQ

What is the HS code for CNC cutter grinder?

The HS code for a numerically controlled CNC cutter grinder is 8460.31.

Can this code be used for manual tool sharpeners?

No, manual or non-numerically controlled tool and cutter grinders are classified under HS code 8460.39. The 8460.31 code is strictly for CNC-equipped models.
