Nonmetallic Mineral Product Manufacturing

Analysis

NAICS 327 is the 2022 subsector for nonmetallic mineral product manufacturing. Census lists 382 example activities under it in the official index.

County Business Patterns counts 15,317 US establishments in this code in 2023, employing 412,320 people at an average annual payroll of $69,317 per employee (51st percentile of national industries). 31% of the establishments have fewer than five employees, which is close to the national mix.

Across its national industries Census lists 382 index entries; typical ones are advanced and technical ceramic products manufacturing, adobe bricks manufacturing, flat glass (e.g., float, plate) manufacturing and ashtrays, glass, made in glass making plants.

Its goods appear in 481 statistical lines of the US tariff schedule, mostly under headings 7013 (glassware of a kind used for table, kitchen, toilet…), 6907 (ceramic flags and paving, hearth or wall tiles; ceramic…) and 7010 (carboys, bottles, flasks, jars, pots, vials, ampoules and…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.

It splits into 5 more detailed codes. The largest by establishments is 3273 (Cement and Concrete Product Manufacturing) with 9,134.

Its more detailed codes are 3271 Clay Product and Refractory Manufacturing (1,036 establishments), 3272 Glass and Glass Product Manufacturing (1,541 establishments), 3273 Cement and Concrete Product Manufacturing (9,134 establishments), 3274 Lime and Gypsum Product Manufacturing (265 establishments) and 3279 Other Nonmetallic Mineral Product Manufacturing (3,341 establishments).

Official definition

The Nonmetallic Mineral Product Manufacturing subsector is based on the transformation of 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.

The Nonmetallic Mineral Product Manufacturing subsector includes establishments that manufacture bricks, refractories, ceramic products, and glass and glass products, such as plate glass and containers. Also included are cement and concrete products, lime, gypsum, and other nonmetallic mineral products including abrasive products, ceramic plumbing fixtures, statuary, cut stone products, and mineral wool. The products are used in a wide range of activities from construction and heavy and light manufacturing to articles for personal use.

Mining, beneficiating, and manufacturing activities often occur in a single location. Separate receipts will be collected for these activities whenever possible. When receipts cannot be broken out between mining and manufacturing, establishments that mine or quarry nonmetallic minerals, beneficiate the nonmetallic minerals, and further process the nonmetallic minerals into a more finished manufactured product are classified based on the primary activity of the establishment. A mine that manufactures a small amount of finished products is classified in Sector 21, Mining, Quarrying, and Oil and Gas Extraction. An establishment that mines whose primary output is a more finished manufactured product is classified in the Manufacturing sector.

Excluded from the Nonmetallic Mineral Product Manufacturing subsector are establishments that primarily beneficiate mined nonmetallic minerals. Beneficiation is the process whereby the extracted material is reduced to particles that can be separated into mineral and waste, the former suitable for further processing or direct use. Beneficiation establishments are included in Sector 21, Mining, Quarrying, and Oil and Gas Extraction.
