Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals
Analysis
NAICS 334515 is the 2022 national industry for instrument manufacturing for measuring and testing electricity and electrical signals, part of 33451 (Navigational, Measuring, Electromedical, and Control Instruments Manufacturing). Census lists 87 example activities under it in the official index.
County Business Patterns counts 672 US establishments in this code in 2023, employing 29,914 people at an average annual payroll of $116,561 per employee (90th percentile of national industries). 32% of the establishments have fewer than five employees, which is close to the national mix.
Its index entries, the activities Census uses to assign businesses to this code, include alternator and generator testers manufacturing, ampere-hour meters manufacturing, analyzers for testing electrical characteristics… and audiofrequency oscillators manufacturing, among 87 in all.
Its goods appear in 31 statistical lines of the US tariff schedule, mostly under headings 9030 (oscilloscopes, spectrum analyzers and other instruments and…), 9031 (measuring or checking instruments, appliances and machines…) and 9028 (gas, liquid or electricity supply or production meters…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Between 2018 and 2023 the number of establishments fell 7% and employment fell 1%. 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.
For example, manufacturing electronic monitoring, evaluating, and other electronic support equipment for navigational, radar, and sonar systems are classified in 334511 (Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing) instead.
Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing instruments for measuring and testing the characteristics of electricity and electrical signals. Examples of products made by these establishments are circuit and continuity testers, voltmeters, ohm meters, wattmeters, multimeters, and semiconductor test equipment.
