Analysis
NAICS 333519 is the 2022 national industry for rolling mill and other metalworking machinery manufacturing, part of 33351 (Metalworking Machinery Manufacturing). Census lists 25 example activities under it in the official index.
Between 2018 and 2023 the number of establishments fell 22% and employment fell 25%. 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 289 US establishments in this code in 2023, employing 10,371 people at an average annual payroll of $79,337 per employee (68th percentile of national industries). 23% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 5th of the 5 codes at this level within Metalworking Machinery Manufacturing, with 5% of them.
Its index entries, the activities Census uses to assign businesses to this code, include assembly machines (i.e., wire making equipment)…, bar mill machinery, metalworking, manufacturing, billet mill machinery, metalworking, manufacturing and blooming and slabbing mill machinery, metalworking…, among 25 in all.
Its goods appear in 16 statistical lines of the US tariff schedule, mostly under headings 8463 (other machine tools for working metal or cermets, without…), 8455 (metal-rolling mills and rolls therefor; parts thereof) and 8479 (machines and mechanical appliances having individual…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Official definition
