Analysis

NAICS 333612 is the 2022 national industry for speed changer, industrial high-speed drive, and gear manufacturing, part of 33361 (Engine, Turbine, and Power Transmission Equipment Manufacturing). Census lists 8 example activities under it in the official index.

County Business Patterns counts 205 US establishments in this code in 2023, employing 10,759 people at an average annual payroll of $72,166 per employee (56th percentile of national industries). 16% of the establishments have fewer than five employees, which points to larger operations.

Its index entries, the activities Census uses to assign businesses to this code, include drives, high-speed industrial (except hydrostatic)…, gearmotors (i.e., power transmission equipment)…, gears, power transmission (except aircraft, motor vehicle)… and motors, gear, manufacturing, among 8 in all.

Between 2018 and 2023 the number of establishments fell 8% and employment fell 8%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.

Its goods appear in 16 statistical lines of the US tariff schedule, mostly under headings 8483 (transmission shafts (including camshafts and crankshafts)…) and 8501 (electric motors and generators (excluding generating sets)). That link is how import data is matched to domestic producers, for example in trade-remedy cases.

Census lists 3 related activities that belong elsewhere, most often in 336350, 336413 and 333996. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
