Primary Metal Manufacturing: NAICS 331

About the Primary Metal Manufacturing subsector

The primary metal manufacturing subsector is part of the manufacturing sector.

Industries in the Primary Metal Manufacturing subsector smelt and/or refine ferrous and nonferrous metals from ore, pig or scrap, using electrometallurgical and other process metallurgical techniques. Establishments in this subsector also manufacture metal alloys and superalloys by introducing other chemical elements to pure metals. The output of smelting and refining, usually in ingot form, is used in rolling, drawing, and extruding operations to make sheet, strip, bar, rod, or wire, and in molten form to make castings and other basic metal products.

North American Industry Classification System

The primary metal manufacturing subsector consists of these industry groups:

Iron and Steel Mills and Ferroalloy Manufacturing: NAICS 3311
Steel Product Manufacturing from Purchased Steel: NAICS 3312
Alumina and Aluminum Production and Processing: NAICS 3313
Nonferrous Metal (except Aluminum) Production and Processing: NAICS 3314
Foundries: NAICS 3315
