Analysis
NAICS 333618 is the 2022 national industry for other engine equipment manufacturing, part of 33361 (Engine, Turbine, and Power Transmission Equipment Manufacturing). Census lists 17 example activities under it in the official index.
Between 2018 and 2023 the number of establishments fell 14% and employment rose 7%. 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.
By establishments it ranks 1st of the 4 codes at this level within Engine, Turbine, and Power Transmission Equipment Manufacturing, with 29.3% of them.
County Business Patterns counts 263 US establishments in this code in 2023, employing 42,686 people at an average annual payroll of $73,956 per employee (60th percentile of national industries). 23% of the establishments have fewer than five employees, which points to larger operations.
Census lists 5 related activities that belong elsewhere, most often in 3363, 33641, 333611 and 333612. 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.
Its index entries, the activities Census uses to assign businesses to this code, include diesel and semidiesel engines manufacturing, electric outboard motors manufacturing, engines, diesel and semidiesel, manufacturing and engines, diesel locomotive, manufacturing, among 17 in all.
