FAQ

What work fits NAICS 327992?
  • Production and bulk shipment of ground calcium carbonate or limestone filler with specified mesh sizes for laboratory testing or material formulation.
  • Supply of calcined clay or processed kaolin delivered as bulk powder for use in coatings or sealants procured by government entities.
  • Grinding and packaging of diatomaceous earth or other inert mineral powders for filtration or absorbent applications as finished bulk lots.
  • Heat-treatment and milling of mineral powders to meet specified particle size distributions, moisture content, and certification requirements for testing or manufacturing.
When is NAICS 327992 a weak fit?
  • Primary metal smelting or alloy production reduces minerals to metals rather than grinding or treating them as bulk powders.
  • Mineral extraction and quarrying covers excavation and rock removal, which is outside this code that focuses on post-extraction processing.
  • Chemical manufacturing of mineral-derived compounds produces synthesized chemical reagents or compounds rather than physically grinding or thermally treating mineral materials.
What solicitation language points to NAICS 327992?
  • Specifications list particle size distribution (mesh or micron), moisture content, bulk packaging units, and required mineral purity tests or certificates of analysis.
  • Line items request delivery of finished bulk mineral powders with lab certificates of analysis and lot traceability rather than installation or fabrication services.
  • Contract labor categories include mill operator, calciner technician, or pulverizer operator and require equipment such as ball mills, classifiers, or calciners.
