Analysis
NAICS 334519 is the 2022 national industry for other measuring and controlling device manufacturing, part of 33451 (Navigational, Measuring, Electromedical, and Control Instruments Manufacturing). Census lists 117 example activities under it in the official index.
County Business Patterns counts 913 US establishments in this code in 2023, employing 34,818 people at an average annual payroll of $87,628 per employee (76th percentile of national industries). 33% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 9 codes at this level within Navigational, Measuring, Electromedical, and Control Instruments Manufacturing, with 18.1% of them.
Census lists 12 related activities that belong elsewhere, most often in 339112, 334511, 334512 and 334513. 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 abrasion testing machines manufacturing, accelerometers (except aerospace type) manufacturing, actinometers, meteorological, manufacturing and aircraft engine instruments manufacturing, among 117 in all.
Its goods appear in 359 statistical lines of the US tariff schedule, mostly under headings 9102 (wrist watches, pocket watches and other watches, including…), 9101 (wrist watches, pocket watches and other watches, including…) and 9105 (other clocks). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
