Variant of North American Industry Classification System (NAICS) 2022 Version 1.0 for Energy sector

Non E - Industries not included in the energy sector

This category comprises all NAICS codes that do not relate to energy industries.

31-33e - Manufacturing, non E

This category comprises the portion of NAICS sector 31-33 'Manufacturing' that does not relate to energy industries.

333 - Machinery manufacturing

This subsector comprises establishments primarily engaged in manufacturing industrial and commercial machinery. These establishments assemble parts into components, subassemblies and complete machines. They may make the parts themselves, using general metal-working processes, or purchase them.

Establishments tend to specialize in producing machinery designed for particular applications, and this is reflected in the structure of the industry groups and industries. A broad distinction exists between general-purpose machinery, that is designed to be used in a variety of industrial applications, such as pumping or machining, and special-purpose machinery, that is designed to be used in a particular industry, such as agriculture or printing. The first three industry groups consist of establishments that produce special-purpose machinery. Establishments that produce general-purpose machinery are classified in the remaining industry groups.

Establishments primarily engaged in rebuilding machinery are included in the same industry as establishments manufacturing the particular type of new machinery. Unless otherwise specified, establishments primarily engaged in manufacturing parts, designed for use solely or principally with a particular machine, are classified in the same industry as establishments manufacturing that type of machinery.

3331 - Agricultural, construction and mining machinery manufacturing

This industry group comprises establishments primarily engaged in manufacturing machinery designed for use in the agriculture, construction and mining industries.

3332 - Industrial machinery manufacturing

This industry group comprises establishments primarily engaged in manufacturing machinery designed for use in specific manufacturing industries.

3333 - Commercial and service industry machinery manufacturing

This industry group comprises establishments primarily engaged in manufacturing machinery for use in commercial and service industries.

3334 - Ventilation, heating, air-conditioning and commercial refrigeration equipment manufacturing

This industry group comprises establishments primarily engaged in manufacturing ventilation, heating, air-conditioning and commercial refrigeration equipment.

3335 - Metalworking machinery manufacturing

This industry group comprises establishments primarily engaged in manufacturing metal cutting and forming machine tools (except hand tools), and related products. The machine tools included in this industry are those not supported in the hands of an operator when in use. Establishments primarily engaged in manufacturing industrial moulds; tools, dies, jigs and fixtures; machine tool accessories and attachments; and rolls are included.

3336 - Engine, turbine and power transmission equipment manufacturing

This industry group comprises establishments primarily engaged in manufacturing turbines and turbine generator sets; internal combustion engines (except automotive gasoline and aircraft); and speed changers, industrial high-speed drives and gears. Establishments primarily engaged in manufacturing wind- and solar-powered turbine generators and windmills for generating electric power are included.

3339 - Other general-purpose machinery manufacturing

This industry group comprises establishments, not classified to any other industry group, primarily engaged in manufacturing machinery that is not designed for use in any specific industry.
