Analysis
NAICS 33451 is the 2022 NAICS industry for navigational, measuring, electromedical, and control instruments manufacturing, part of 3345 (Navigational, Measuring, Electromedical, and Control Instruments Manufacturing). Census lists 568 example activities under it in the official index.
County Business Patterns counts 5,050 US establishments in this code in 2023, employing 414,694 people at an average annual payroll of $106,063 per employee (87th percentile of national industries). 30% of the establishments have fewer than five employees, which is close to the national mix.
Census lists 8 related activities that belong elsewhere, most often in 33422, 33531, 33593 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 568 index entries; typical ones are arc lamp units, electrotherapeutic (except infrared…, acceleration indicators and systems components, aerospace…, air flow controllers (except valves), air-conditioning and… and absorption analyzers, industrial process type (e.g.….
Its goods appear in 564 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.
It splits into 9 more detailed codes. The largest by establishments is 334519 (Other Measuring and Controlling Device Manufacturing) with 913.
