Analysis
NAICS 33999 is the 2022 NAICS industry for all other miscellaneous manufacturing, part of 3399 (Other Miscellaneous Manufacturing). Census lists 137 example activities under it in the official index.
Between 2018 and 2023 the number of establishments fell 16% and employment fell 12%. 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.
Census lists 12 related activities that belong elsewhere, most often in 3391, 33991, 33992 and 33993. 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.
County Business Patterns counts 4,547 US establishments in this code in 2023, employing 99,947 people at an average annual payroll of $65,683 per employee (44th percentile of national industries). 49% of the establishments have fewer than five employees, which is close to the national mix.
Across its national industries Census lists 137 index entries; typical ones are coaxial mechanical face seals manufacturing, accordions and parts manufacturing, buckles and buckle parts (including shoe) manufacturing and brooms, hand and machine, manufacturing.

That link is how import data is matched to domestic producers, for example in trade-remedy cases.
