U.S. imports of machine tools for material removal by electro-chemical, electron-beam, ionic-beam, or plasma arc processes (nesoi) (HS 845690) totaled $7.7M in May 2026, traded with 25 countries.
Importers of Machine Tools for Material Removal by Electro-Chemical, Electron-Beam, Ionic-Beam, or Plasma Arc Processes (NESOI) paid $847K in duties in May 2026 — an effective duty rate of 11% on $7.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Machine Tools for Material Removal by Electro-Chemical, Electron-Beam, Ionic-Beam, or Plasma Arc Processes (NESOI) imports of $7.7M in May 2026 ran 22% above the year-to-date monthly average of $6.3M.
Last updated: May 2026 dataElectro-chemical, electron-beam, ionic-beam, and plasma arc machine tools occupy a specialized niche in precision manufacturing, enabling non-contact material removal that conventional cutting cannot achieve on hardened or exotic materials. The US schedule divides this heading into metalworking variants (8456903100) and non-metal applications using beam or similar processes (8456907100). New Zealand leads US import supply under this heading, followed by Italy and Germany — an unusual supplier profile that reflects niche OEM relationships rather than high-volume commodity trade. Importers should verify whether specific configurations trigger Section 301 exposure based on country of origin.

Classification hinges on the workpiece material, not the process technology. If the machine is designed and marketed for metalworking, it falls under 8456903100. Machines using beam or plasma arc processes on non-metallic materials — such as ceramics or composites — are classified under 8456907100. When a machine is dual-purpose, the principal use at time of importation typically governs; consult a licensed customs broker for a binding ruling.
Depending on country of origin, certain machine tools may be subject to Section 301 tariffs. New Zealand, Italy, and Germany are among the leading suppliers; goods from these origins are generally not subject to Section 301, but importers sourcing from other origins should confirm current applicability with their customs broker before entry.
