Analysis
NAICS 332613 is the 2022 national industry for spring manufacturing, part of 33261 (Spring and Wire Product Manufacturing). Census lists 21 example activities under it in the official index.
County Business Patterns counts 341 US establishments in this code in 2023, employing 15,671 people at an average annual payroll of $60,997 per employee (35th percentile of national industries). 17% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 2nd of the 2 codes at this level within Spring and Wire Product Manufacturing, with 32.4% of them.
Its index entries, the activities Census uses to assign businesses to this code, include automobile suspension springs, heavy gauge metal…, coiled springs (except clock, watch), light gauge, made…, coiled springs, heavy gauge metal, manufacturing and disk and ring springs, heavy gauge metal, manufacturing, among 21 in all.
Its goods appear in 15 statistical lines of the US tariff schedule, mostly under headings 7320 (springs and leaves for springs, of iron or steel) and 7419 (other articles of copper). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Between 2018 and 2023 the number of establishments fell 7% and employment fell 10%. 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.
