Official definition
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.

Why do company counts differ?
The U.S. Economic Census counts establishments with paid employees that operated during the census year, including businesses that may have since closed. Its industry classifications draw on business-reported information and government records. SICCODE.com's counts reflect verified business records currently available for purchase, with classifications based on documented business activities. Differences in reporting periods, database coverage, classification methods and verification criteria mean the totals may differ.
