HS code for Spark erosion machine: 8456.30

Machine-tools, for working any material by removal of material, operated by electro-discharge processes.

Classification of spark erosion machine under HS 8456.30

Spark erosion machines, also known as Electrical Discharge Machines (EDM), are classified under HS code 8456.30. This code is part of Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8456 specifically addresses machine tools for working any material by removal of material, operated by processes other than traditional mechanical cutting. Subheading 8456.30 is reserved for those machines that utilize electro-discharge processes. In these machines, material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. This classification is precise because it focuses on the physical-chemical process used for material removal rather than the type of material being worked. The machines must be designed to perform material removal to be classified here; machines that use sparks for other purposes, such as marking or surface hardening without significant material removal, may fall elsewhere. The technical sophistication of these machines, which often include CNC (Computer Numerical Control) systems, does not change their primary classification under 8456.30.

Codes often confused with 8456.30

Common mistake. Spark erosion machines are often confused with other non-mechanical machine tools. For instance, laser beam machines are classified under 8456.11, and plasma arc machines are under 8456.40. Another common error is classifying them under 8459, which covers traditional mechanical drilling or milling machines. The key distinction is the method of material removal; if it involves electrical discharge (sparks), 8456.30 is the correct code. Hand-held tools that might use similar processes are also excluded and usually fall under 8467.

Top exporters and importers of HS 845630 (the code used for spark erosion machine), 2025

In 2025, the largest exporter of HS 845630 (the code used for spark erosion machine) 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).
