Analysis
NAICS 48691 is the 2022 NAICS industry for pipeline transportation of refined petroleum products, part of 4869 (Other Pipeline Transportation).
It has only one more detailed code, 486910, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments grew 36% and employment rose 11%. 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 849 US establishments in this code in 2023, employing 9,350 people at an average annual payroll of $145,469 per employee (96th percentile of national industries). 48% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 2 codes at this level within Other Pipeline Transportation, with 96% of them.
