Definition: NAICS 21232 Sand, gravel, clay, and ceramic, and refractory minerals mining and quarrying

This industry comprises (1) establishments primarily engaged in developing the mine site and/or mining, quarrying, dredging for sand and gravel, or mining clay, (e.g., china clay, paper clay and slip clay) and (2) preparation plants primarily engaged in beneficiating (e.g., washing, screening, and grinding) sand and gravel, clay, and ceramic and refractory minerals.

Cross-References. Establishments primarily engaged in--

Calcining, dead burning, or otherwise processing (i.e., beyond basic preparation) clay or refractory minerals--are classified in Industry 32799, All Other Nonmetallic Mineral Product Manufacturing;
Shaping, molding, baking, burning, or hardening nonclay ceramics, clay and nonclay refractories, and structural clay products--are classified in Industry 32712, Clay Building Material and Refractories Manufacturing; and
Shaping, molding, glazing, and firing pottery, ceramics, and plumbing fixtures--are classified in Industry 32711, Pottery, Ceramics and Plumbing Fixture Manufacturing.

Historical comparability

Not Comparable NAICS 21232, Sand, gravel, clay, and ceramic, and refractory minerals mining and quarrying, is not directly comparable between 2002 and 1997. See the Bridge Between 2002 NAICS and 1997 NAICS for changes to constituent industries.

In comparisons with data before 1997, 1997 NAICS 21232 corresponds to the sum of multiple SIC codes. See the Bridge Between 1997 NAICS and 1987 SIC.

In the following table, both 1997 and 2002 data are classified by 1997 NAICS, so that the two years are comparable.

Comparative Statistics: 2002 and 1997
