Analysis
NAICS 212390 is the 2022 national industry for other nonmetallic mineral mining and quarrying, part of 21239 (Other Nonmetallic Mineral Mining and Quarrying). Census lists 149 example activities under it in the official index.
Census lists 8 related activities that belong elsewhere, most often in 21231, 21232, 327992 and 325180. 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.
Its index entries, the activities Census uses to assign businesses to this code, include abrasive stones (e.g., emery, grindstones, hones, pumice)…, abrasives, natural (except sand), mining and/or…, agate mining and/or beneficiating and alabaster mining and/or beneficiating, among 149 in all.
For example, mining or quarrying stone are classified in 21231 (Stone Mining and Quarrying) instead.
County Business Patterns publishes no national count for it, either because the code is out of the survey's scope or because the figures are suppressed to protect individual businesses.
Official definition
This industry comprises establishments primarily engaged in developing the mine site, mining, and/or milling or otherwise beneficiating (i.e., preparing) nonmetallic minerals (except coal, stone, sand, gravel, clay, and ceramic and refractory minerals). Drylake brine operations are included in this industry, as well as establishments engaged in producing the specified minerals from underground and open pit mines.
Illustrative Examples:
