B North American Industry Classification System

The North American Industry Classification System (NAICS) provides common definitions of the industrial structure of Canada, Mexico and the United States. Developed jointly by the statistical agencies of these countries, NAICS was adopted in 1997 and revised in 2002 and 2007 to increase comparability among the three countries and to add new industries.

The NAICS numbering system is a six-digit code:

  • first two digits designate the sector
  • third digit designates the subsector
  • fourth digit designates the industry group
  • fifth digit designates the industry
  • sixth digit can indicate another level of detail (to include additional detail, a country can create national industries and indicate that in the sixth digit.)

Figure B.1 Example of NAICS code designation

NAICS Canada 2007 consists of 20 sectors, 102 subsectors, 324 industry groups, 718 industries and 928 national industries. (It replaces NAICS Canada 2002.) Table B.1 lists the 20 sectors.

The four three-digit NAICS codes (subsectors) analysed in this summary report are as follows:

322 Paper Manufacturing
This subsector comprises establishments primarily engaged in manufacturing pulp, paper and paper products. The manufacture of pulp involves separating the cellulose fibres from other impurities in wood, used paper or other fibre sources. The manufacture of paper involves matting these fibres into a sheet. Converted paper products are produced from paper and other materials by various cutting and shaping techniques.

324 Petroleum and Coal Product Manufacturing
This subsector comprises establishments primarily engaged in transforming crude petroleum and coal into intermediate and end products. The dominant process is petroleum refining, which separates crude petroleum into components or fractions through such techniques as cracking and distillation.
Exclusion(s): Establishments primarily engaged in
– manufacturing chemicals and chemical preparations from refined petroleum and coal
products (325, Chemical Manufacturing)

325 Chemical Manufacturing
This subsector comprises establishments primarily engaged in manufacturing chemicals and chemical preparations, from organic and inorganic raw materials.
Exclusion(s): Establishments primarily engaged in
– field processing of crude petroleum and natural gas (211, Oil and Gas Extraction)
– beneficiating mineral ores (212, Mining and Quarrying [except Oil and Gas])
– processing crude petroleum and coal (324, Petroleum and Coal Products Manufacturing)
– smelting and refining ores and concentrates (331, Primary Metal Manufacturing)

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 (332, Fabricated Metal Product

The remaining 17 three-digit NAICS codes (subsectors) belonging to the Manufacturing sector are as follows:

311  Food Manufacturing
312  Beverage and Tobacco Product Manufacturing
313  Textile Mills
314  Textile Product Mills
315  Clothing Manufacturing
316  Leather and Allied Product Manufacturing
321  Wood Product Manufacturing
323  Printing and Related Support Activities
326  Plastics and Rubber Products Manufacturing
327  Non-Metallic Mineral Product Manufacturing
332  Fabricated Metal Product Manufacturing
333  Machinery Manufacturing
334  Computer and Electronic Product Manufacturing
335  Electrical Equipment, Appliance and Component Manufacturing
336  Transportation Equipment Manufacturing
337  Furniture and Related Product Manufacturing
339  Miscellaneous Manufacturing
