Analysis
NAICS 332993 is the 2022 national industry for ammunition (except small arms) manufacturing, part of 33299 (All Other Fabricated Metal Product Manufacturing). Census lists 31 example activities under it in the official index.
County Business Patterns counts 60 US establishments in this code in 2023, employing 15,596 people at an average annual payroll of $104,406 per employee (86th percentile of national industries). 30% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 6th of the 6 codes at this level within All Other Fabricated Metal Product Manufacturing, with 1.2% of them.
Its index entries, the activities Census uses to assign businesses to this code, include adapters, bombcluster, manufacturing, ammunition (i.e., more than 30 mm., more than 1.18 inch)…, ammunition loading and assembling plants and arming and fusing devices, missile, manufacturing, among 31 in all.
Its goods appear in 4 statistical lines of the US tariff schedule, mostly under headings 3603 (safety fuses; detonating cords; percussion or detonating…) and 9306 (bombs, grenades, torpedoes, mines, missiles and similar…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Census lists 4 related activities that belong elsewhere, most often in 332992, 325920, 325998 and 336414. 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.
