U.S. imports of numerically controlled machines for working metal tube, pipe, hollow section & bar (HS 846251) totaled $4.6M in June 2026, traded with 11 countries.
Importers of Numerically Controlled Machines for Working Metal Tube, Pipe, Hollow Section & Bar paid $683K in duties in June 2026 — an effective duty rate of 15% on $4.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Numerically Controlled Machines for Working Metal Tube, Pipe, Hollow Section & Bar imports of $4.6M in June 2026 ran 26% above the year-to-date monthly average of $3.7M.
CNC tube benders, end-forming machines, and rotary-draw bending systems for metal tube, pipe, hollow sections, and bar stock are the core equipment of this heading, serving the automotive exhaust, aerospace, and oil-and-gas fabrication sectors. Italy leads US supply, with Germany second and the Netherlands third — a European concentration that reflects the region's strength in precision tube-processing machinery. The US schedule divides the heading by condition only: used or rebuilt (8462510040) versus new (8462510080), with presses excluded from both lines and classified separately. Importers should confirm that a machine's primary function is tube or bar working rather than pressing, as that distinction determines heading eligibility.

The 846251 heading explicitly excludes presses, which are classified under separate headings covering metal-working presses (such as heading 8462 subheadings for hydraulic or mechanical presses). A machine that forms tube or pipe primarily through pressing action — rather than bending, end-forming, or rotary draw — should be evaluated under those press headings. The distinction turns on the machine's operating principle.
Automotive exhaust systems, aerospace hydraulic lines, and oil-and-gas piping fabrication are the primary end-use sectors. These industries often require tight bend-radius tolerances and material certifications that favor established European suppliers like those in Italy and Germany. Importers should factor in whether the machine's specifications — mandrel capacity, CLR ratios, axis count — align with their production requirements before committing to a supplier.
