Analysis
NAICS 321918 is the 2022 national industry for other millwork (including flooring), part of 32191 (Millwork). Census lists 35 example activities under it in the official index.
County Business Patterns counts 1,445 US establishments in this code in 2023, employing 32,379 people at an average annual payroll of $51,828 per employee (19th percentile of national industries). 42% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 3 codes at this level within Millwork, with 44.7% of them.
Its index entries, the activities Census uses to assign businesses to this code, include bamboo flooring manufacturing, baseboards, floor, wood, manufacturing, brackets, wood, manufacturing and clear and finger joint wood moldings manufacturing, among 35 in all.
Its goods appear in 42 statistical lines of the US tariff schedule, mostly under headings 4409 (wood (including strips and friezes for parquet flooring…), 4418 (builders' joinery and carpentry of wood, including cellular…) and 4412 (plywood, veneered panels and similar laminated wood). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Between 2018 and 2023 the number of establishments fell 7% 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.
