Analysis
NAICS 332919 is the 2022 national industry for other metal valve and pipe fitting manufacturing, part of 33291 (Metal Valve Manufacturing). Census lists 17 example activities under it in the official index.
Census lists 7 related activities that belong elsewhere, most often in 332912, 332911, 332913 and 326199. 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.
County Business Patterns counts 212 US establishments in this code in 2023, employing 13,428 people at an average annual payroll of $69,533 per employee (52nd 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 aerosol valves manufacturing, boiler couplings and drains, plumbing and heating-type…, breakers, vacuum, plumbing, manufacturing and couplings, hose, metal (except fluid power), manufacturing, among 17 in all.
Its goods appear in 45 statistical lines of the US tariff schedule, mostly under headings 7307 (tube or pipe fittings (for example, couplings, elbows…), 7412 (copper tube or pipe fittings (for example couplings…) and 8481 (taps, cocks, valves and similar appliances, for pipes…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
For example, manufacturing fluid power valves and hose fittings are classified in 332912 (Fluid Power Valve and Hose Fitting Manufacturing) instead.
Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing metal valves (except industrial valves, fluid power valves, fluid power hose fittings, and plumbing fixture fittings and trim).
