Analysis
NAICS 327420 is the 2022 national industry for gypsum product manufacturing, part of 32742 (Gypsum Product Manufacturing). Census lists 25 example activities under it in the official index.
County Business Patterns counts 172 US establishments in this code in 2023, employing 11,475 people at an average annual payroll of $89,517 per employee (77th 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 16% and employment rose 17%. 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.
Its index entries, the activities Census uses to assign businesses to this code, include art goods (e.g., gypsum, plaster of paris) manufacturing, board, gypsum, manufacturing, cement, Keene's (i.e., tiling plaster), manufacturing and columns, architectural or ornamental plaster work…, among 25 in all.
Its goods appear in 4 statistical lines of the US tariff schedule, mostly under headings 6809 (articles of plaster or of compositions based on plaster) and 2520 (gypsum; anhydrite; plasters (consisting of calcined gypsum…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
For example, operating gypsum mines or quarries are classified in 212390 (Other Nonmetallic Mineral Mining and Quarrying) instead.
