Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables
Analysis
NAICS 334513 is the 2022 national industry for instruments and related products manufacturing for measuring, displaying, and controlling industrial process variables, part of 33451 (Navigational, Measuring, Electromedical, and Control Instruments Manufacturing). Census lists 72 example activities under it in the official index.
County Business Patterns counts 889 US establishments in this code in 2023, employing 39,166 people at an average annual payroll of $86,668 per employee (75th percentile of national industries). 33% 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 334515, 339112, 334519 and 334516. 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 absorption analyzers, industrial process type (e.g.…, acidity (i.e., pH) instruments, industrial process type…, analyzers, industrial process control type, manufacturing and annunciators, relay and solid-state types, industrial…, among 72 in all.
Between 2018 and 2023 the number of establishments grew 8% and employment rose 13%. 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 34 statistical lines of the US tariff schedule, mostly under headings 9026 (instruments and apparatus for measuring or checking the…), 9032 (automatic regulating or controlling instruments and…) and 8531 (electric sound or visual signaling apparatus (for example…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing instruments and related devices for measuring, displaying, indicating, recording, transmitting, and controlling industrial process variables. These instruments measure, display, or control (monitor, analyze, and so forth) industrial process variables, such as temperature, humidity, pressure, vacuum, combustion, flow, level, viscosity, density, acidity, concentration, and rotation.
