HS Code for Ultrasonic machining center

Ultrasonic machining centers are classified under HS code 8456.20. This classification is part of Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8456 is specifically designated for machine tools that work by removing material through specialized processes rather than traditional mechanical cutting. Subheading 8456.20 covers those machines operated by ultrasonic processes. These machines use high-frequency electrical energy converted into mechanical vibrations to drive a tool that, in combination with an abrasive slurry, erodes the workpiece. This technology is primarily used for machining hard, brittle materials such as glass, ceramics, and quartz. The classification applies to the complete machine tool designed to perform these specific removal operations.

Products Included

• Ultrasonic drilling machines for ceramic substrates
• Ultrasonic milling centers for glass components
• Ultrasonic grinding machines for semiconductor wafers
• CNC ultrasonic machining centers for precision engineering
• Ultrasonic micro-machining equipment

Common Misclassification

These machines are frequently misclassified under HS code 8457.10, which covers traditional machining centers for working metal. However, 8456 is more specific for machines using non-traditional material removal processes like ultrasonics. Another common error is confusing them with ultrasonic cleaning machines, which fall under HS code 8479.89, as they do not remove material to shape a part. Additionally, if the machine uses a laser in combination with ultrasonics, it might be misclassified under 8456.11, but the primary material removal mechanism determines the final classification.

FAQ

What is the HS code for ultrasonic machining center?

The HS code for machine tools operated by ultrasonic processes for the removal of material is 8456.20.

Can this code be used for ultrasonic welding machines?

No, ultrasonic welding machines do not remove material; they join it. They are typically classified under HS code 8515.80.
