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.
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)
3365 - Railroad Rolling Stock Manufacturing
This industry group comprises establishments primarily engaged in manufacturing and rebuilding locomotives and railroad cars, of any type or gauge, including frames and parts. The manufacture of rapid transit cars and special-purpose self-propelled railroad equipment, such as rail layers, ballast distributors, rail-tamping equipment and other railway track maintenance equipment is included in this industry.
33651 - Railroad Rolling Stock Manufacturing
This industry comprises establishments primarily engaged in manufacturing and rebuilding locomotives and railroad cars, of any type or gauge, including frames and parts. The manufacture of rapid transit cars and special-purpose self-propelled railroad equipment, such as rail layers, ballast distributors, rail-tamping equipment and other railway track maintenance equipment is included in this industry.
Exclusion(s):
Establishments primarily engaged in:
- manufacturing mining rail cars (See 33313 Mining and Oil and Gas Field Machinery Manufacturing)
