Analysis

NAICS 212311 is the 2022 national industry for dimension stone mining and quarrying, part of 21231 (Stone Mining and Quarrying). Census lists 30 example activities under it in the official index.

Between 2018 and 2023 the number of establishments grew 28% and employment rose 27%. 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.

County Business Patterns counts 379 US establishments in this code in 2023, employing 4,660 people at an average annual payroll of $57,524 per employee (28th percentile of national industries). 42% of the establishments have fewer than five employees, which is close to the national mix.

Its index entries, the activities Census uses to assign businesses to this code, include argillite mining or quarrying, basalt mining or quarrying, bluestone mining or quarrying and calcareous tufa mining or quarrying, among 30 in all.

Its goods appear in 17 statistical lines of the US tariff schedule, mostly under headings 2516 (granite, porphyry, basalt, sandstone and other monumental…), 2506 (quartz (other than natural sands); quartzite, whether or…) and 2515 (marble, travertine and other calcareous monumental or…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.

For example, dressing dimension stone and manufacturing stone products are classified in 327991 (Cut Stone and Stone Product Manufacturing) instead.
