HS Code for CNC tool grinder

A CNC tool grinder is classified under HS code 846031 because it is a machine-tool specifically designed for sharpening (tool or cutter grinding) and is numerically controlled. These machines are engineered to restore the cutting edge and geometry of various industrial tools, such as drills, end mills, reamers, and hobs, to their original specifications or to modify them for specific applications. The numerical control system provides unparalleled precision and automation, allowing for complex tool geometries to be ground accurately and repeatedly, which is crucial for maintaining tool performance and extending tool life in manufacturing operations.

Products Included

Common Misclassification

Common misclassifications can occur with HS 846039, which covers other sharpening (tool or cutter grinding) machines that are not numerically controlled. The defining characteristic for 846031 is the "numerically controlled" feature. Another point of distinction is from HS 846012, which pertains to numerically controlled flat-surface grinding machines. While both are grinding machines, tool grinders are specialized for sharpening cutting tools, whereas surface grinders are for general flat surface finishing. Similarly, HS 846022, covering other numerically controlled grinding machines (e.g., cylindrical, centerless), is distinct because its primary function is not tool sharpening but other forms of precision grinding.
