1 - Goods-Producing Sector

6 - Manufacturing

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.

331 - Primary Metal Manufacturing

This subsector comprises establishments primarily engaged in smelting and refining ferrous and non-ferrous metals from ore, pig or scrap in blast or electric furnaces. Metal alloys are made with the introduction of other chemical elements. The output of smelting and refining, usually in ingot form, is used in rolling and drawing operations to produce sheet, strip, bars, rods and wire, and in molten form to produce castings and other basic metal products.

  • Exclusion(s):

    Establishments primarily engaged in:

    • manufacturing metal forgings or stampings (See 332 Fabricated Metal Product Manufacturing)
3311 - Iron and Steel Mills and Ferro-Alloy Manufacturing

This industry group comprises establishments primarily engaged in smelting iron ore and steel scrap to produce pig iron in molten or solid form; converting pig iron into steel by the removal, through combustion in furnaces, of the carbon in the iron. These establishments may cast ingots only, or also produce iron and steel basic shapes, such as plates, sheets, strips, rods and bars, and other fabricated products. Electric arc furnace mini-mills are included. Establishments primarily engaged in producing ferro-alloys are also included.

3312 - Steel Product Manufacturing from Purchased Steel

This industry group comprises establishments primarily engaged in manufacturing iron and steel pipe and tube, drawing steel wire, and rolling steel shapes, from purchased steel.

3313 - Alumina and Aluminum Production and Processing

This industry group comprises establishments primarily engaged in extracting alumina from bauxite ore; producing aluminum from alumina; refining aluminum by any process; and rolling, drawing, extruding and alloying aluminum and aluminum-based alloy basic shapes.

3314 - Non-Ferrous Metal (except Aluminum) Production and Processing

This industry group comprises establishments primarily engaged in smelting, refining, rolling, drawing, extruding and alloying non-ferrous metal, except aluminum.

  • Exclusion(s):

    Establishments primarily engaged in:

    • smelting, refining, rolling, drawing, extruding and alloying aluminum (See 3313 Alumina and Aluminum Production and Processing)
3315 - Foundries

This industry group comprises establishments primarily engaged in pouring molten metal into moulds or dies to form castings.

  • Exclusion(s):

    Establishments primarily engaged in:

    • forging and stamping metal (See 3321 Forging and Stamping)
