This major group covers establishments primarily engaged in manufacturing industrial and commercial machinery, equipment, and computer systems. It includes producers of engines and turbines, farm and garden machinery, construction and mining equipment, and materials-handling systems such as cranes, elevators, and conveyors. Businesses manufacturing metalworking machines, pumps, compressors, packaging machinery, and refrigeration systems are also included, as well as those producing computer hardware, office equipment, and vending or service industry machines. Generally, this group includes power-driven tools and machinery used in industrial operations, but excludes electrical household appliances (classified under Major Group 36) and nonpowered hand tools (classified under Major Group 34).
