Analysis
NAICS 32712 is the 2022 NAICS industry for clay building material and refractories manufacturing, part of 3271 (Clay Product and Refractory Manufacturing).
It has only one more detailed code, 327120, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments fell 13% and employment rose 1%. 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 461 US establishments in this code in 2023, employing 23,500 people at an average annual payroll of $62,594 per employee (38th percentile of national industries). 18% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 2nd of the 2 codes at this level within Clay Product and Refractory Manufacturing, with 44.5% of them.
