Analysis
NAICS 335314 is the 2022 national industry for relay and industrial control manufacturing, part of 33531 (Electrical Equipment Manufacturing). Census lists 22 example activities under it in the official index.
Between 2018 and 2023 the number of establishments fell 18% and employment fell 6%. 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.
County Business Patterns counts 704 US establishments in this code in 2023, employing 33,267 people at an average annual payroll of $80,914 per employee (69th percentile of national industries). 27% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 4 codes at this level within Electrical Equipment Manufacturing, with 39.3% of them.
Its index entries, the activities Census uses to assign businesses to this code, include armature relays manufacturing, brakes and clutches, electromagnetic, manufacturing, brakes, electromagnetic, manufacturing and control circuit devices, magnet and solid-state…, among 22 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…), 8537 (boards, panels, consoles, desks, cabinets and other bases…) and 8504 (electrical transformers, static converters (for example…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
