U.S. imports of Machine Tools Operated by Electro-Discharge Processes (SITC 73113) totaled $15.8M in August 2026, imported from 16 countries.
Importers of Machine Tools Operated by Electro-Discharge Processes 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. Machine Tools Operated by Electro-Discharge Processes 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) equipment removes material through controlled electrical sparks between an electrode and a conductive workpiece, enabling the production of complex cavities and fine features in hardened tool steels and exotic alloys. EDM systems — including sinker, wire, and hole-drilling variants — are widely traded capital goods serving the mold-and-die, aerospace, and precision parts industries. Importers should note that origin-specific Section 301 exposure can materially affect landed cost for equipment sourced from certain Asian manufacturing hubs.

At the SITC level, all electro-discharge machine tools fall within the same category regardless of electrode configuration. At the HTS 10-digit level, however, distinctions between wire-cut EDM and other EDM types may exist. Importers should verify the applicable HTS subheading with a licensed customs broker to ensure correct duty treatment.
CBP may request technical specifications, manufacturer's literature, and a detailed description of the working process to confirm that electrical discharge — rather than a mechanical or chemical process — is the primary material-removal method. A binding ruling can provide classification certainty for high-value capital equipment purchases.
