HS Code for Honing machine

A honing machine is classified under HS code 8460.40. This classification is found within Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8460 specifically applies to machine-tools for deburring, sharpening, grinding, honing, lapping, polishing, or otherwise finishing metal or cermets by means of grinding stones, abrasives, or polishing products. Subheading 8460.40 is the specific designation for honing or lapping machines. These machines are characterized by their function of improving the geometric form and surface texture of a workpiece. Unlike standard grinding, honing uses an abrasive stone that follows a controlled path to create a precision finish, often used in the manufacturing of engine cylinders and hydraulic components. The classification applies regardless of whether the machine is CNC-controlled or manually operated.

Products Included

• Vertical honing machines
• Horizontal honing machines
• CNC honing centers
• Lapping machines for metal finishing
• Cylinder honing machines for automotive repair

Common Misclassification

Honing machines are sometimes misclassified under HS code 8459, which covers machine-tools for drilling, boring, milling, threading, or tapping. While a honing machine may work on a pre-drilled hole, its primary function is finishing (abrasive) rather than cutting or boring (material removal), which places it in 8460. Another common confusion is with other subheadings of 8460, such as 8460.12 or 8460.22, which are reserved for flat-surface or cylindrical grinding machines. The distinction is the specific abrasive action; honing and lapping are distinct processes from grinding and have their own dedicated subheading at 8460.40.

FAQ

What is the HS code for a honing machine?

The HS code for a honing machine is 8460.40, which includes both honing and lapping machine-tools.

Is a CNC honing machine classified differently?

No, both manual and CNC-operated honing machines are classified under 8460.40, though they may be distinguished at the statistical suffix level in some national tariffs.
