Analysis
NAICS 335931 is the 2022 national industry for current-carrying wiring device manufacturing, part of 33593 (Wiring Device Manufacturing). Census lists 39 example activities under it in the official index.
By establishments it ranks 1st of the 2 codes at this level within Wiring Device Manufacturing, with 71.9% of them.
County Business Patterns counts 397 US establishments in this code in 2023, employing 24,429 people at an average annual payroll of $68,914 per employee (51st percentile of national industries). 19% of the establishments have fewer than five employees, which points to larger operations.
Its index entries, the activities Census uses to assign businesses to this code, include arrestors and coils, lighting, manufacturing, automotive electrical switches manufacturing, bus bars, electrical conductors (except switchgear-type)… and caps and plugs, attachment, electric, manufacturing, among 39 in all.
Its goods appear in 21 statistical lines of the US tariff schedule, mostly under headings 8536 (electrical apparatus for switching or protecting electrical…), 8535 (electrical apparatus for switching or protecting electrical…) and 8533 (electrical resistors (including rheostats and…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Census lists 3 related activities that belong elsewhere, most often in 334417, 335932 and 334419. 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.
