NAICS 333248

Overview

The North American Industry Classification System (NAICS) is the framework U.S. federal statistical programs use to group business establishments for collecting, analyzing, and disseminating economic data. Developed under OMB and jointly maintained with Canada and Mexico, NAICS replaced SIC in 1997 and is currently published in its 2022 vintage. ¹

Under 2022 NAICS, code 333248 denotes “All Other Industrial Machinery Manufacturing.” Official materials describe this industry as establishments primarily engaged in manufacturing industrial machinery not classified elsewhere (e.g., excluding agricultural, construction/mining, sawmill/woodworking, plastics/rubber, paper, textile, printing, food manufacturing‑type, and semiconductor making machinery). ³
