Analysis

NAICS 334517 is the 2022 national industry for irradiation apparatus manufacturing, part of 33451 (Navigational, Measuring, Electromedical, and Control Instruments Manufacturing). Census lists 19 example activities under it in the official index.

County Business Patterns counts 121 US establishments in this code in 2023, employing 12,598 people at an average annual payroll of $121,309 per employee (91st percentile of national industries). 20% of the establishments have fewer than five employees, which points to larger operations.

By establishments it ranks 9th of the 9 codes at this level within Navigational, Measuring, Electromedical, and Control Instruments Manufacturing, with 2.4% of them.

Between 2018 and 2023 the number of establishments fell 11% and employment rose 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.

Its index entries, the activities Census uses to assign businesses to this code, include beta-ray irradiation equipment manufacturing, computerized axial tomography (CT/CAT) scanners…, CT/CAT (computerized axial tomography) scanners… and fluoroscopes manufacturing, among 19 in all.

Its goods appear in 14 statistical lines of the US tariff schedule, mostly under headings 9022 (apparatus based on the use of X-rays or of alpha, beta…) and 9018 (instruments and appliances used in medical, surgical…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
