U.S. imports of broaching machines, metalworking (SITC 73173) totaled $10.8M in April 2026, traded with 9 countries.
Importers of Broaching Machines, Metalworking paid $52K in duties in April 2026 — an effective duty rate of 0.5% on $10.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Broaching Machines, Metalworking imports of $10.8M in April 2026 ran 250% above the year-to-date monthly average of $3.1M.
Last updated: April 2026 dataBroaching machines use a toothed, multi-point cutting tool pulled or pushed across a workpiece to produce precision internal profiles—keyways, splines, and non-circular bores—in a single pass, making them indispensable in automotive drivetrain and aerospace component manufacturing. Classification under SITC 73173 is distinct from other metal-removal machine tools, and importers should confirm whether a given machine's primary function is broaching rather than a combined operation, as misclassification can affect applicable duty treatment. Demand tracks closely with production volumes in transmission and turbine component sectors, where tight dimensional tolerances make broaching the preferred finishing method.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A broaching machine is defined by its use of a multi-tooth broach tool that removes material in a single linear stroke, producing a finished profile in one pass. If a machine performs broaching as its primary function, it classifies under this heading rather than under general milling or grinding categories, regardless of whether it is horizontal or vertical in orientation.
Automotive drivetrain manufacturing—particularly transmission housings, gear blanks, and splined shafts—is the dominant end-use sector. Aerospace turbine disk and structural component production is a secondary driver, where broaching delivers the repeatable tight tolerances required by quality management standards such as AS9100.
