Analysis
NAICS 33324 is the 2022 NAICS industry for industrial machinery manufacturing, part of 3332 (Industrial Machinery Manufacturing). Census lists 218 example activities under it in the official index.
County Business Patterns counts 2,836 US establishments in this code in 2023, employing 111,497 people at an average annual payroll of $98,245 per employee (83rd percentile of national industries). 31% of the establishments have fewer than five employees, which is close to the national mix.
Census lists 5 related activities that belong elsewhere, most often in 3331, 33399, 33341 and 33331. 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.
Across its national industries Census lists 218 index entries; typical ones are bakery machinery and equipment manufacturing, etching equipment, semiconductor, manufacturing, bandsaws, woodworking-type, manufacturing and additive manufacturing machinery manufacturing.
Between 2018 and 2023 the number of establishments fell 8% and employment rose 2%. 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 115 statistical lines of the US tariff schedule, mostly under headings 8465 (machine tools (including machines for nailing, stapling…), 8438 (machinery, not specified or included elsewhere in this…) and 8486 (machines and apparatus of a kind used solely or principally…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Official definition
This industry comprises establishments primarily engaged in manufacturing industrial machinery, such as food and beverage manufacturing machinery, semiconductor manufacturing machinery, sawmill and woodworking machinery (except handheld), machinery for making paper and paper products, printing and binding machinery and equipment, textile making machinery, and machinery for making plastics and rubber products.
