Analysis
NAICS 3326 is the 2022 industry group for spring and wire product manufacturing, part of 332 (Fabricated Metal Product Manufacturing).
It has only one more detailed code, 33261, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 1,051 US establishments in this code in 2023, employing 34,731 people at an average annual payroll of $61,524 per employee (36th percentile of national industries). 24% of the establishments have fewer than five employees, which points to larger operations.
Between 2018 and 2023 the number of establishments fell 5% 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.
By establishments it ranks 7th of the 9 codes at this level within Fabricated Metal Product Manufacturing, with 2% of them.
