NAICS 238290
Overview
The North American Industry Classification System (NAICS) is the governmentwide standard for organizing establishments to produce statistics about the U.S. economy. Developed under the Office of Management and Budget with Canada and Mexico, NAICS replaced SIC in 1997 and is revised every five years; the current vintage used in the 2022 Economic Census is NAICS 2022. 1
NAICS 238290 covers specialty trade contractors primarily engaged in installing or dismantling building and industrial equipment other than plumbing, HVAC, or electrical systems; it also includes machine rigging and millwrighting. Examples include automated and revolving doors, conveyor systems, dumbwaiters, dust‑collection equipment, elevators, small incinerators, pneumatic tube systems, and built‑in central vacuum systems. Work may involve new construction, additions, alterations, and maintenance or repairs. 3
