Analysis
NAICS 321912 is the 2022 national industry for cut stock, resawing lumber, and planing, part of 32191 (Millwork). Census lists 38 example activities under it in the official index.
County Business Patterns counts 708 US establishments in this code in 2023, employing 20,181 people at an average annual payroll of $54,958 per employee (25th percentile of national industries). 25% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments fell 16% 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.
By establishments it ranks 3rd of the 3 codes at this level within Millwork, with 21.9% of them.
Its index entries, the activities Census uses to assign businesses to this code, include blanks, wood (e.g., bowling pins, handles, textile…, boards, wood, resawing purchased lumber, bobbin blocks and blanks, wood, manufacturing and bowling pin blanks manufacturing, among 38 in all.
Census lists 3 related activities that belong elsewhere, most often in 321113, 321918 and 337215. 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.
