U.S. imports of plasma arc machine tools for material removal (HS 845640) totaled $7.8M in April 2026, traded with 15 countries.
Importers of Plasma Arc Machine Tools for Material Removal paid $491K in duties in April 2026 — an effective duty rate of 20% on $2.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Plasma Arc Machine Tools for Material Removal imports of $7.8M in April 2026 ran 11% above the year-to-date monthly average of $7.0M.
Last updated: April 2026 dataPlasma arc cutting machines use a superheated ionized gas jet to sever electrically conductive metals — steel, aluminum, and stainless — at speeds and thicknesses that make them a standard tool in structural fabrication, shipbuilding, and heavy equipment manufacturing. Canada and Mexico are the leading US suppliers under this heading, a supply pattern consistent with integrated North American manufacturing under USMCA. The US schedule separates numerically controlled metalworking plasma arc tools (8456401010) from non-NC metalworking units (8456401090) and non-metalworking plasma arc applications (8456409000). CNC plasma tables are the dominant commercial form, widely used in job shops and OEM fabrication facilities.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Plasma arc machine tools originating in Canada or Mexico and meeting USMCA rules of origin qualify for preferential (duty-free or reduced) tariff treatment under that agreement. Importers must obtain a valid USMCA certification of origin from the producer or exporter and ensure the goods meet the applicable tariff shift or regional value content requirement. A licensed customs broker can verify whether a specific machine qualifies.
Multi-process machines present a classification challenge because they span both 845611 (laser) and 845640 (plasma arc). CBP's general rule is to classify by the machine's essential character or, if that cannot be determined, by the heading that appears last in numerical order. In practice, importers should request a binding ruling from CBP, supported by the manufacturer's specifications showing the primary cutting technology and the proportion of use in each mode.
