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.

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.

3331 - Agricultural, Construction and Mining Machinery Manufacturing

This industry group comprises establishments primarily engaged in manufacturing machinery designed for use in the agriculture, construction and mining industries.

33311 - Agricultural Implement Manufacturing

This industry comprises establishments primarily engaged in manufacturing machinery for use in performing farm operations, such as the preparation and maintenance of soil; planting, harvesting or threshing; field spraying; and preparing crops for market; or for use in horticultural and residential lawn care. Establishments primarily engaged in manufacturing snowblowers are included.

• Exclusion(s):

  Establishments primarily engaged in:

  • manufacturing agricultural hand tools, such as manual shears and non-powered lawn mowers (See 33221 Cutlery and Hand Tool Manufacturing)
  • manufacturing metal corrals, stalls and cattle holders (See 33232 Ornamental and Architectural Metal Products Manufacturing)
  • manufacturing food manufacturing machinery, such as milk processing equipment (See 33329 Other Industrial Machinery Manufacturing)
  • manufacturing farm conveyors and farm elevators (See 33392 Material Handling Equipment Manufacturing)

33312 - Construction Machinery Manufacturing

This industry comprises establishments primarily engaged in manufacturing heavy machinery and equipment of a type used primarily in the construction industry, such as crawler or rubber-tired tractors with bulldozer blade or ripper tooth attachments, front-end loaders, cranes, concrete mixers, power shovels and pavers. Machinery that can be used in both the construction and mining industries is treated as construction machinery. Establishments primarily engaged in manufacturing forestry machinery, such as tree harvesting and handling equipment, are also included.

• Exclusion(s):

  Establishments primarily engaged in:

  • manufacturing farm tractors (See 33311 Agricultural Implement Manufacturing)
  • manufacturing mining and oil and gas field drilling equipment (See 33313 Mining and Oil and Gas Field Machinery Manufacturing)
  • manufacturing industrial plant overhead travelling cranes, hoists, truck-type cranes and hoists, winches, aerial work platforms, and automotive wrecker hoists (See 33392 Material Handling Equipment Manufacturing)
  • manufacturing rail layers, ballast distributors and other railroad track-laying equipment (See 33651 Railroad Rolling Stock Manufacturing)

33313 - Mining and Oil and Gas Field Machinery Manufacturing

This industry comprises establishments primarily engaged in manufacturing mining and oil and gas field industry equipment.

• Exclusion(s):

  Establishments primarily engaged in:

  • manufacturing machinery with both construction and mining uses, including portable rock crushing machinery (See 33312 Construction Machinery Manufacturing)
  • manufacturing coal and ore conveyors (See 33392 Material Handling Equipment Manufacturing)
  • manufacturing underground mining locomotives (See 33651 Railroad Rolling Stock Manufacturing)
  • manufacturing offshore oil and gas well drilling and production platforms (See 33661 Ship and Boat Building)
