Clay Building Material and Refractories Manufacturing
NAICS 327120 · United States · 2022 edition
This industry comprises establishments primarily engaged in shaping, molding, baking, burning, or hardening clay refractories, nonclay refractories, ceramic tile, structural clay tile, brick, and other structural clay building materials. A refractory is a material that will retain its shape and chemical identity when subjected to high temperatures and is used in applications that require extreme resistance to heat, such as furnace linings.

Establishments in this class mine or purchase raw clay and other mineral inputs, then shape, dry, and fire them in high-temperature kilns to produce ceramic tile, structural brick, clay tile, or refractory materials. Refractories are engineered to withstand extreme heat and are used in furnace linings, kilns, incinerators, and industrial process equipment. Day-to-day operations involve heavy machinery, kiln management, material handling, and quality control, often with significant dust and heat exposure.
Questions to investigate
- What are the primary product types — ceramic tile, structural brick, clay tile, or technical refractories?
- What are the primary end-use applications for refractory products — industrial furnaces, kilns, petrochemical, commercial construction?
- What is the age and condition of kiln infrastructure, and is there a documented maintenance and inspection program?
- Is there a documented industrial hygiene program addressing silica dust or other mineral dust exposure?
