Establishments in this class manufacture a wide range of nonmetallic mineral products not covered by more specific NAICS codes — examples include dry-mix concrete products, stucco and stucco products, mica fabrications, synthetic and engineered stones, and resin-coated or ceramic proppants used in oil and gas well completion. Operations typically involve crushing, grinding, mixing, coating, or heat-treating raw mineral inputs, followed by packaging and distribution to industrial or construction customers.
