Product classification
HS code for Ultrasonic machining center: 8456.20
Machine-tools, for working any material by removal of material, operated by ultrasonic processes.
Classification of ultrasonic machining center under HS 8456.20
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.

Codes often confused with 8456.20
Common mistake. 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.
Top exporters and importers of HS 845620 (the code used for ultrasonic machining center), 2025
In 2025, the largest exporter of HS 845620 (the code used for ultrasonic machining center) in UN Comtrade data was Germany, with 27% of world exports; the largest importer in UN Comtrade data was the United States, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
