HS Code 8456.30 – Machine-tools; for working any material by removal of material, operated by electro-discharge processes
HS code 8456.30 is the 6-digit subheading for machine-tools, for working any material by removal of material, operated by electro-discharge processes. It is used for wire EDM machines, sinker EDM machines (die-sinking EDM), hole drilling EDM machines, micro EDM machines and EDM surface finishing machines.
What HS 8456.30 covers
This category includes machine tools that remove material through controlled electrical discharges, commonly known as Electrical Discharge Machining (EDM). This non-conventional machining method is ideal for creating intricate shapes, deep cavities, and processing hard-to-machine conductive materials, regardless of their hardness, such as hardened steel, titanium, and superalloys. EDM machines are vital in mold and die making, aerospace, medical, and automotive industries for producing complex components with high precision and excellent surface finish. The international trade involves specialized manufacturers exporting these high-value capital goods to precision engineering firms worldwide. Key considerations include the ability to machine complex geometries that are impossible with traditional cutting tools, making them indispensable for advanced manufacturing processes.

Codes often confused with 8456.30
Common mistake. Often confused with 845640 (plasma arc machines) due to both using electrical processes, but EDM uses controlled sparks for material erosion, while plasma uses a high-temperature ionized gas jet. Also, 8457 (machining centers) if the EDM aspect is not highlighted.
Top exporters and importers of HS code 845630, 2025
In 2025, the largest exporter of HS code 845630 in UN Comtrade data was Japan, with 28% of world exports; the largest importer in UN Comtrade data was China, with 27% 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).
