Nonmetallic Mineral Product Manufacturing: NAICS 327

About the Nonmetallic Mineral Product Manufacturing subsector

The nonmetallic mineral product manufacturing subsector is part of the manufacturing sector.

The Nonmetallic Mineral Product Manufacturing subsector transforms mined or quarried nonmetallic minerals, such as sand, gravel, stone, clay, and refractory materials, into products for intermediate or final consumption. Processes used include grinding, mixing, cutting, shaping, and honing. Heat often is used in the process and chemicals are frequently mixed to change the composition, purity, and chemical properties for the intended product. For example, glass is produced by heating silica sand to the melting point (sometimes combined with cullet or recycled glass) and then drawn, floated, or blow molded to the desired shape or thickness. Refractory materials are heated and then formed into bricks or other shapes for use in industrial applications.

North American Industry Classification System

The nonmetallic mineral product manufacturing subsector consists of these industry groups:

Clay Product and Refractory Manufacturing: NAICS 3271
Glass and Glass Product Manufacturing: NAICS 3272
Cement and Concrete Product Manufacturing: NAICS 3273
Lime and Gypsum Product Manufacturing: NAICS 3274
Other Nonmetallic Mineral Product Manufacturing: NAICS 3279
