Variant of NAICS 2012 - Energy sector

Non E - Industries not included in the energy sector

This category comprises all NAICS codes that do not relate to energy industries.

31-33e - Manufacturing, non E

This category comprises the portion of NAICS sector 31-33 'Manufacturing' that does not relate to energy industries.

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)

  • 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.
