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.

326 - Plastics and Rubber Products Manufacturing

This subsector comprises establishments primarily engaged in making goods by processing raw rubber and plastics materials. Rubber- and plastics-based activities are combined in the same subsector because the technical properties of these polymers are related.

Generally, establishments classified in this subsector manufacture products made of just one material, rubber or plastics, with the major exception of tire manufacturing.

  • Exclusion(s):

    Establishments primarily engaged in:

    • manufacturing synthetic resins from basic organic chemicals (See 325210 Resin and Synthetic Rubber Manufacturing)
    • compounding plastics resins from recycled materials (See 32599 All Other Chemical Product Manufacturing)

3262 - Rubber Product Manufacturing

This industry group comprises establishments primarily engaged in processing natural, synthetic or reclaimed rubber materials into intermediate or final products using such processes as vulcanizing, cementing, moulding, extruding and lathe-cutting.

32621 - Tire Manufacturing

This industry comprises establishments primarily engaged in manufacturing tires and inner tubes from natural and synthetic rubber; and retreading or rebuilding tires.

  • Exclusion(s):

    Establishments primarily engaged in:

    • manufacturing synthetic rubber (See 32521 Resin and Synthetic Rubber Manufacturing)
    • retailing and repairing tires (See 44132 Tire Dealers)
    • repairing tires (See 81119 Other Automotive Repair and Maintenance)
32622 - Rubber and Plastic Hose and Belting Manufacturing

This industry comprises establishments primarily engaged in manufacturing rubber and plastic hose (reinforced) and belting from natural and synthetic rubber and/or plastics resins.

  • Exclusion(s):
