HS Code for Lapping machine

Lapping machines are classified under HS code 8460.40. This code is situated within Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8460 covers machine-tools for deburring, sharpening, grinding, honing, lapping, polishing, or otherwise finishing metal or cermets. The classification 8460.40 is dedicated to honing or lapping machines. These machines are distinguished from grinding machines by the nature of the abrasive process. Lapping involves the use of a loose abrasive slurry or a very fine-grained stone to achieve extreme surface flatness and finish, rather than the high-volume material removal associated with grinding. The classification applies to machines that operate by removing material to achieve precise tolerances on metal workpieces.

Products Included

• Precision flat lapping machines
• Cylindrical lapping machines
• Vertical and horizontal honing machines
• Double-sided lapping systems
• Engine cylinder honing tools (machine-tool grade)

Common Misclassification

Lapping machines are frequently confused with grinding machines classified under 8460.12, 8460.22, or 8460.29. The distinction lies in the precision and the method of abrasion; grinding uses a bonded abrasive wheel, while lapping uses a lap plate and abrasive compound. They may also be misclassified under 8464 if they are intended for working stone, ceramics, or glass, as 8460 is strictly for metal or cermets. Additionally, manual hand tools for lapping do not fall here and are instead classified in Chapter 82.
