North American Industry Classification System (NAICS) 2002

31-33 - Manufacturing

This sector comprises establishments primarily engaged in the physical or chemical transformation of materials or substances into new products. These products may be finished, in the sense that they are ready to be used or consumed, or semi-finished, in the sense of becoming a raw material for an establishment to use in further manufacturing. Related activities, such as the assembly of the component parts of manufactured goods; the blending of materials; and the finishing of manufactured products by dyeing, heat-treating, plating and similar operations are also treated as manufacturing activities. Manufacturing establishments are known by a variety of trade designations, such as plants, factories or mills.

Manufacturing establishments may own the materials which they transform or they may transform materials owned by other establishments. Manufacturing may take place in factories or in workers' homes, using either machinery or hand tools.

Certain activities involving the transformation of goods are classified in other sectors. Some examples are post-harvest activities of agricultural establishments, such as crop drying; logging; the beneficiating of mineral ores; the production of structures by construction establishments; and various activities conducted by retailers, such as meat cutting and the assembly of products such as bicycles and computers.

336 - Transportation Equipment Manufacturing

This subsector comprises establishments primarily engaged in manufacturing equipment for transporting people and goods. The industry groups are based on the various modes of transport - road, rail, air and water. Three industry groups are based on road transportation equipment - for complete vehicles, for body and trailer manufacture and for parts.

Establishments primarily engaged in rebuilding equipment and parts are included in the same industry as establishments manufacturing new products.

  • Exclusion(s):

    Establishments primarily engaged in:

    • manufacturing equipment designed for moving materials and goods on industrial sites, construction sites, in logging camps and other off-highway locations (See 333 Machinery Manufacturing)

3363 - Motor Vehicle Parts Manufacturing

This industry group comprises establishments primarily engaged in manufacturing motor vehicle parts, including engines. Establishments that rebuild motor vehicle parts are included in this industry group, in the same industry as the manufacture of new parts.

  • Exclusion(s):

    Establishments primarily engaged in:

    • manufacturing motor vehicle plastic parts (See 32619 Other Plastic Product Manufacturing)
    • manufacturing rubber and plastic hose and belts (See 32622 Rubber and Plastic Hose and Belting Manufacturing)
    • manufacturing motor vehicle hardware (See 33251 Hardware Manufacturing)
    • manufacturing motor vehicle coil and leaf springs (See 33261 Spring and Wire Product Manufacturing)
    • manufacturing diesel engines and parts for motor vehicles (See 33361 Engine, Turbine and Power Transmission Equipment Manufacturing)
33631 - Motor Vehicle Gasoline Engine and Engine Parts Manufacturing

This industry comprises establishments primarily engaged in manufacturing and rebuilding motor vehicle gasoline engines and engine parts, whether or not for vehicular use.

  • Exclusion(s):
