SITCSection 7
U.S. imports of boring machines for metal (not elsewhere specified) (SITC 73146) totaled $2.5M in April 2026, traded with 6 countries.
Importers of Boring Machines for Metal (Not Elsewhere Specified) paid $66K in duties in April 2026 — an effective duty rate of 14% on $462K in dutiable value, based on actual customs collections rather than the published tariff schedule. Boring Machines for Metal (Not Elsewhere Specified) imports of $2.5M in April 2026 ran 17% above the year-to-date monthly average of $2.1M.
Last updated: April 2026 dataJig borers, line-boring machines, and other dedicated boring equipment that cannot be classified as boring-milling machines or way-type unit head machines fall under SITC 73146. The heading's residual scope means classification depends on confirming that the machine performs boring as its primary function without a significant integrated milling capability that would push it into the boring-milling headings. These machines are critical in precision toolroom and die-making environments where bore geometry tolerances are tighter than standard machining centers can reliably achieve.

The distinction turns on whether the machine has meaningful integrated milling capability. A machine designed and marketed primarily for boring — with limited or no milling function — belongs in 73146. If the machine is designed to perform both boring and milling as co-equal operations, it belongs in the boring-milling headings (73144 for CNC, 73145 for non-CNC). Manufacturer catalogs and the machine's spindle and table specifications are the primary classification evidence.
A jig borer with CNC control but without significant milling capability remains in the boring-machine category. However, if the CNC jig borer also performs milling as a designed function, it may shift to the CNC boring-milling heading 73144. The functional design intent — not merely the presence of CNC control — governs the classification decision.
