Last updated: August 2026 dataGear hobbers, gear shapers, bevel-gear cutters, and gear grinding or finishing machines occupy this heading, serving the automotive, wind-energy, and industrial gearbox sectors where tooth-profile accuracy is tightly toleranced. Germany and Switzerland dominate US import supply, reflecting the concentration of precision gear-machine builders in Central Europe, with Japan also a significant source. The US schedule distinguishes gear cutting machines (lines 8461401010 through 8461401090) from gear grinding and finishing machines (8461405020 through 8461405070), with further splits by machine type — hobbers, shapers, bevel-gear machines — condition, and value. Imports from China may be subject to Section 301 tariffs.

The schedule carves out gear hobbers and gear shapers as distinct new-machine lines (8461401030, 8461401040, and 8461401050) separate from bevel-gear cutting machines (8461401020) and a residual 'other' category for new gear cutting machines (8461401090). Used or rebuilt gear cutting machines of all types consolidate into 8461401010.
Importers should provide the original manufacturer's specification sheet, a bill of sale or appraisal confirming used/rebuilt status, and a commercial invoice stating the transaction value. Because the $3,025 value threshold and condition (used vs. new) both determine the correct 10-digit line, accurate valuation documentation is essential to avoid misclassification between lines such as 8461405020 (used/rebuilt) and 8461405060 or 8461405070 (new, over $3,025).
