U.S. imports of numerically controlled punching, notching & nibbling machines for flat metal products (HS 846242) totaled $10.7M in April 2026, traded with 10 countries.
Importers of Numerically Controlled Punching, Notching & Nibbling Machines for Flat Metal Products paid $1.7M in duties in April 2026 — an effective duty rate of 17% on $10.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Numerically Controlled Punching, Notching & Nibbling Machines for Flat Metal Products imports of $10.7M in April 2026 ran 21% below the year-to-date monthly average of $13.5M.
Last updated: April 2026 dataCNC turret punch presses, laser-punch combination machines, and nibbling machines for flat sheet metal are the primary equipment types in this heading, central to precision sheet-metal fabrication for electronics enclosures, HVAC components, and industrial panels. Japan leads US supply, with Germany second and Finland — home to major turret punch press manufacturers — a notable third source. The US schedule separates used or rebuilt N/C punching and notching machines (8462420040) from new ones (8462420080), and importantly, combined punching-and-shearing machines are included here rather than in the shearing headings. Importers of high-value CNC turret presses should confirm whether integrated laser or plasma cutting heads affect classification.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A machine that combines CNC punching with laser cutting presents a classification challenge. If the punching function is principal, it may remain under 846242; if the laser cutting function predominates, it could fall under a different heading covering laser-beam machining. CBP's essential character analysis under GRI 3(b) applies, and a binding ruling is advisable for high-value combination machines before importation.
Finland is home to globally recognized manufacturers of CNC turret punch presses and combination punch-shear systems, particularly for the sheet-metal fabrication industry. Importers sourcing from Finnish manufacturers benefit from established quality reputations but should plan for European lead times and verify current trade-measure applicability with their customs broker.
