NAICS 327992 - Ground or Treated Mineral and Earth Manufacturing
This page includes content generated by AI. It is intended for general guidance only and should be verified for your specific situation.
What is NAICS 327992
NAICS code 327992 encompasses establishments primarily engaged in the advanced processing of nonmetallic minerals, including clays, ceramic minerals, refractory minerals, barite, and other miscellaneous earth materials. This sector involves processes such as calcining and dead burning, which go beyond simple beneficiation to alter the chemical or physical properties of these raw materials for industrial applications. Businesses in this sector play a critical role in producing essential mineral inputs used in manufacturing, construction, and high-temperature industrial processes. Government agencies contract with these establishments to secure reliable, high-quality mineral products necessary for infrastructure projects, defense applications, and scientific research. The specialized nature of these materials often requires strict quality control and compliance with federal standards, making government procurement essential for ensuring supply chain integrity and performance.
