Analysis
NAICS 3274 is the 2022 industry group for lime and gypsum product manufacturing, part of 327 (Nonmetallic Mineral Product Manufacturing). Census lists 33 example activities under it in the official index.
County Business Patterns counts 265 US establishments in this code in 2023, employing 15,543 people at an average annual payroll of $86,504 per employee (75th percentile of national industries). 21% of the establishments have fewer than five employees, which points to larger operations.
Between 2018 and 2023 the number of establishments fell 15% and employment rose 9%. 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.
By establishments it ranks 5th of the 5 codes at this level within Nonmetallic Mineral Product Manufacturing, with 1.7% of them.
Across its national industries Census lists 33 index entries; typical ones are agricultural lime manufacturing and art goods (e.g., gypsum, plaster of paris) manufacturing.
Its goods appear in 8 statistical lines of the US tariff schedule, mostly under headings 2522 (quicklime, slaked lime and hydraulic lime, other than…), 6809 (articles of plaster or of compositions based on plaster) and 2518 (dolomite, whether or not calcined or sintered, including…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
