U.S. imports of Electro-Discharge Machine Tools for Material Removal (HS 845630) totaled $15.8M in August 2026, imported from 16 countries.
Importers of Electro-Discharge Machine Tools for Material Removal paid $2.2M in duties in August 2026, an average duty rate of 14.14% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Electro-Discharge Machine Tools for Material Removal imports of $15.8M in August 2026 ran 31% above the year-to-date monthly average of $12.1M.
Last updated: August 2026 dataElectro-discharge machining (EDM) removes material through controlled electrical sparks between a tool electrode and workpiece, enabling the production of complex cavities and fine features in hardened tool steels and exotic alloys used in mold-making, aerospace, and precision die manufacturing. Japan dominates US supply under this heading — a reflection of Japanese manufacturers' long-standing leadership in wire-EDM and sinker-EDM technology. The US schedule distinguishes traveling-wire (wire-cut) EDM tools (8456301020) from other NC electro-discharge metalworking tools (8456301050), non-NC versions (8456301070), and non-metalworking EDM applications (8456305000). Thailand and Singapore are also notable suppliers, often as assembly or distribution hubs for Japanese-designed equipment.

The US schedule explicitly separates traveling-wire EDM machines (8456301020) from other electro-discharge metalworking tools. Wire-cut EDMs use a continuously fed wire electrode to cut profiles, while sinker EDMs use a shaped electrode to erode cavities. The machine type must be identified from the manufacturer's technical documentation; misclassifying a sinker EDM as a wire-cut unit (or vice versa) can result in an incorrect duty rate and potential CBP penalties.
Country of origin for complex machinery is determined by substantial transformation — the country where the last process that fundamentally changes the article's character or use occurs. Assembly of Japanese components in Thailand may or may not constitute substantial transformation depending on the complexity of the assembly and the value added. Importers uncertain about origin should seek a CBP binding ruling before importation to avoid misclassification and potential antidumping exposure.
