Analysis
NAICS 32518 is the 2022 NAICS industry for other basic inorganic chemical manufacturing, part of 3251 (Basic Chemical Manufacturing).
It has only one more detailed code, 325180, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 705 US establishments in this code in 2023, employing 41,447 people at an average annual payroll of $106,159 per employee (87th percentile of national industries). 17% of the establishments have fewer than five employees, which points to larger operations.
Between 2018 and 2023 the number of establishments grew 9% and employment rose 3%. 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 2nd of the 5 codes at this level within Basic Chemical Manufacturing, with 26.9% of them.
