Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance
Analysis
NAICS 811310 is the 2022 national industry for commercial and industrial machinery and equipment (except automotive and electronic) repair and maintenance, part of 81131 (Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance). Census lists 41 example activities under it in the official index.
Census lists 12 related activities that belong elsewhere, most often in 8111, 811210, 213112 and 238190. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
County Business Patterns counts 22,907 US establishments in this code in 2023, employing 219,835 people at an average annual payroll of $73,266 per employee (58th percentile of national industries). 60% of the establishments have fewer than five employees, which marks it as a small-business industry.
Its index entries, the activities Census uses to assign businesses to this code, include agricultural machinery and equipment repair and maintenance…, armature rewinding services (except on an assembly line or…, blade sharpening, commercial and industrial machinery and… and cargo container repair and maintenance services, among 41 in all.
For example, automotive repair (except welding) and maintenance are classified in 8111 (Automotive Repair and Maintenance) instead.
Between 2018 and 2023 the number of establishments grew 4% and employment rose 8%. 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.
Official definition
This industry comprises establishments primarily engaged in the repair and maintenance of commercial and industrial machinery and equipment. Establishments in this industry either sharpen/install commercial and industrial machinery blades and saws or provide welding (e.g., automotive, general) repair services; or repair agricultural and other heavy and industrial machinery and equipment (e.g., forklifts and other material handling equipment, machine tools, commercial refrigeration equipment, construction equipment, and mining machinery).
