HS Code 8456.20 – Machine-tools; for working any material by removal of material, operated by ultrasonic processes
HS code 8456.20 is the 6-digit subheading for machine-tools, for working any material by removal of material, operated by ultrasonic processes. It is used for ultrasonic drilling machines, ultrasonic milling machines, ultrasonic grinding machines, ultrasonic polishing machines and rotary ultrasonic machining centers.
What HS 8456.20 covers
This HS code covers machine tools that remove material using ultrasonic vibrations, often in conjunction with an abrasive slurry. Ultrasonic machining (USM) is particularly effective for processing hard, brittle, and non-conductive materials like ceramics, glass, quartz, and advanced composites, where conventional machining methods are difficult or impossible. These machines are crucial for industries such as aerospace, medical device manufacturing, optics, and electronics, where precision shaping of delicate or tough materials is required without introducing thermal or chemical changes. International trade involves specialized manufacturers exporting to high-tech production facilities globally. The market is driven by the increasing use of advanced materials that demand non-conventional machining solutions, making these machines vital for cutting-edge product development and manufacturing.

Codes often confused with 8456.20
Common mistake. Can be confused with 845630 (electro-discharge machines) or 845690 (other processes) if the specific ultrasonic mechanism isn't clearly identified. Also, general machining centers (e.g., 8457) might be misclassified if the ultrasonic aspect is overlooked.
Top exporters and importers of HS code 845620, 2025
In 2025, the largest exporter of HS code 845620 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).
