Analysis
NAICS 3335 is the 2022 industry group for metalworking machinery manufacturing, part of 333 (Machinery Manufacturing).
It has only one more detailed code, 33351, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments fell 11% and employment fell 11%. 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 5,772 US establishments in this code in 2023, employing 134,208 people at an average annual payroll of $69,334 per employee (51st percentile of national industries). 34% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 2nd of the 7 codes at this level within Machinery Manufacturing, with 26.6% of them.
