Analysis
NAICS 49312 is the 2022 NAICS industry for refrigerated warehousing and storage, part of 4931 (Warehousing and Storage).
It has only one more detailed code, 493120, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 1,376 US establishments in this code in 2023, employing 66,236 people at an average annual payroll of $56,905 per employee (27th percentile of national industries). 22% of the establishments have fewer than five employees, which points to larger operations.
Between 2018 and 2023 the number of establishments fell 4% and employment rose 15%. 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 3rd of the 4 codes at this level within Warehousing and Storage, with 6.4% of them.
