North American Industry Classification System (NAICS) 2007
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.

Establishments primarily engaged in:
- manufacturing metal products by rolling, drawing, extruding, alloying or casting (See 331 Primary Metal Manufacturing)
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.
334 - Computer and Electronic Product Manufacturing
This subsector comprises establishments primarily engaged in manufacturing computers, computer peripheral equipment, communications equipment, and similar electronic products, as well as components for such products. The computer and electronic product manufacturing industries employ production processes that are characterized by the design and use of integrated circuits and the application of highly specialized miniaturization technologies.
335 - Electrical Equipment, Appliance and Component Manufacturing
This subsector comprises establishments primarily engaged in manufacturing products that generate, distribute and use electrical power.
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)
337 - Furniture and Related Product Manufacturing
This subsector comprises establishments primarily engaged in manufacturing furniture and related products. The processes used in the manufacture of furniture are standard methods of forming materials and assembling components, including cutting, moulding and laminating. The design of the article, for both aesthetic and functional qualities, is an important aspect of the production process. Design services may be performed by the furniture establishment's own work force or may be purchased from industrial designers. Furniture is classified based on the application for which it is designed. For example, an upholstered sofa is treated as household furniture, although it may also be used in hotels or offices.
Furniture is also classified according to the component material from which it is made. Furniture made from more than one material is classified based on the material used in the frame, or if there is no frame, the predominant component material. Upholstered household furniture is classified as such, without regard to the frame material.
Furniture may be produced on a stock or custom basis and may be shipped assembled or unassembled (knock-down). Establishments primarily engaged in manufacturing furniture frames and parts are included.
Exclusion(s):
Establishments primarily engaged in:
- manufacturing furniture hardware (See 332 Fabricated Metal Product Manufacturing)
