Analysis
NAICS 332313 is the 2022 national industry for plate work manufacturing, part of 33231 (Plate Work and Fabricated Structural Product Manufacturing). Census lists 40 example activities under it in the official index.
Between 2018 and 2023 the number of establishments grew 17% and employment rose 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 1,726 US establishments in this code in 2023, employing 47,243 people at an average annual payroll of $63,960 per employee (41st percentile of national industries). 25% of the establishments have fewer than five employees, which is close to the national mix.
Its index entries, the activities Census uses to assign businesses to this code, include airlocks, fabricated metal plate work, manufacturing, baffles, fabricated metal plate work, manufacturing, bins, fabricated metal plate work, manufacturing and breechings, fabricated metal plate work, manufacturing, among 40 in all.
Its goods appear in 1 statistical lines of the US tariff schedule, mostly under headings 8907 (other floating structures (for example, rafts, tanks…). 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 332410, 332420 and 333415. 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.
Official definition
