HS Code for Gear grinding machine

Gear grinding machines are classified under HS code 8461.40. This classification is part of Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8461 is dedicated to machine-tools for planing, shaping, slotting, broaching, gear cutting, gear grinding, or gear finishing. The gear grinding machine is a specialized tool used to remove small amounts of material from gear teeth using an abrasive wheel to achieve high precision and a smooth surface finish. This is a critical step in the manufacturing of high-performance gears used in automotive transmissions, aerospace components, and industrial gearboxes. The classification applies to machines that utilize abrasive processes to refine the profile and lead of gear teeth after they have been roughed out by other processes like hobbing or shaping.

Common Misclassification

A common misclassification occurs with HS code 8460, which covers general-purpose grinding machines. While 8460 includes surface and cylindrical grinders, it specifically excludes machines dedicated to gear grinding, which must be classified under 8461.40. Importers also sometimes confuse these with 8459 (milling machines) if the machine uses a hobbing-like motion, but if the tool is an abrasive wheel, 8461.40 is the correct designation. Furthermore, if the machine is for sharpening tools rather than grinding gears, it would fall under 8460.31 or 8460.39.

FAQ

What is the HS code for gear grinding machine?

The correct HS code for a gear grinding machine is 8461.40, as it is a machine-tool specifically for gear grinding by removing metal.

Are CNC gear grinders classified differently than manual ones?

No, both CNC and manual gear grinding machines are classified under 8461.40, although the specific sub-heading may vary by country-specific tariff schedules for statistical purposes.
