SITCSection 7
U.S. imports of gear cutting, gear grinding & gear finishing machines, metalworking (SITC 73175) totaled $8.4M in July 2026, traded with 10 countries.
Importers of Gear Cutting, Gear Grinding & Gear Finishing Machines, Metalworking paid $605K in duties in July 2026 — an effective duty rate of 8.5% on $7.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataGear cutting, grinding, and finishing machines occupy a specialized niche within metalworking capital equipment, producing the involute tooth profiles required for power-transmission gears used in automotive, wind-energy, and industrial gearbox applications. The SITC 73175 heading encompasses hobbing machines, gear shapers, gear grinders, and gear-lapping equipment—each suited to different tooth geometries and surface-finish requirements. Buyers should verify whether a machine is configured for soft-cutting (pre-heat-treat) or hard-finishing (post-heat-treat) operations, as this distinction affects both the machine's classification and its suitability for a given production process.

Yes. SITC 73175 groups gear cutting (including hobbing and shaping), gear grinding, and gear finishing machines together under a single heading because all three perform operations specifically directed at forming or refining gear tooth profiles. The distinction between them matters for technical specification and procurement, but not for SITC classification at this level.
Standard commercial documentation—commercial invoice, packing list, and bill of lading—is required. For high-value capital equipment, a detailed technical specification sheet identifying the machine's function, capacity (module range, workpiece diameter), and CNC control type supports accurate classification. Some gear grinding machines may also require an Export Control Classification Number (ECCN) review by the exporting country, particularly if they meet certain precision thresholds under dual-use export control regimes.
