Analysis
NAICS 3117 is the 2022 industry group for seafood product preparation and packaging, part of 311 (Food Manufacturing).
It has only one more detailed code, 311710, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 516 US establishments in this code in 2023, employing 29,132 people at an average annual payroll of $60,776 per employee (34th percentile of national industries). 29% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 9th of the 9 codes at this level within Food Manufacturing, with 1.7% of them.
Between 2018 and 2023 the number of establishments fell 7% and employment fell 6%. 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.
