42331

Analysis

NAICS 42331 is the 2022 NAICS industry for lumber, plywood, millwork, and wood panel merchant wholesalers, part of 4233 (Lumber and Other Construction Materials Merchant Wholesalers).

It has only one more detailed code, 423310, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 7,048 US establishments in this code in 2023, employing 130,158 people at an average annual payroll of $80,037 per employee (69th percentile of national industries). 35% of the establishments have fewer than five employees, which is close to the national mix.

By establishments it ranks 1st of the 4 codes at this level within Lumber and Other Construction Materials Merchant Wholesalers, with 38.9% of them.

Between 2018 and 2023 the number of establishments grew 1% and employment rose 1%. 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.
