What this NAICS covers

NAICS 327999 covers manufacturing miscellaneous nonmetallic mineral products not classified elsewhere, producing engineered mineral components, specialty refractories, abrasive or filler shapes, and other formed mineral-based items used in industrial or construction applications.

Federal opportunities under 327999 typically involve contracts to supply custom-formed mineral components, small production runs of specialty refractories or abrasive elements, material certification, dimensional drawings, and delivery to meet project specifications.

FAQ

What work fits NAICS 327999?
  • Manufacture and deliver custom-shaped refractory bricks or castable refractories specified by thermal tolerance, chemistry, and dimensional drawings for high-temperature applications.
  • Produce bonded abrasive wheels, segments, or blocks to specified grit, hardness, and balancing tolerances with material test certificates and inspection reports.
  • Fabricate mineral-filled molded or pressed components used as insulation blocks, bearing pads, or vibration-damping inserts with supplied inspection and certification documentation.
  • Supply small-batch engineered mineral composite parts machined to drawing tolerances with lot traceability, material certificates, and delivered spare-part kits.
When is NAICS 327999 a weak fit?
  • Precast concrete product manufacturing: production of standard precast concrete elements and large-volume concrete products uses dedicated concrete processes distinct from miscellaneous mineral product fabrication.
  • Glass manufacturing: primary glass forming for containers, flat glass, or fiberglass production involves distinct glass processes and product families outside miscellaneous nonmetallic mineral component fabrication.
  • High-volume ceramic tile or sanitary ware manufacturing: standardized, high-volume ceramic processes for tiles or sanitary fixtures follow separate ceramic product categories rather than custom or miscellaneous mineral product work.
What solicitation language points to NAICS 327999?
  • Scope calls for delivery of mineral-formed components with tight dimensional tolerances, heat or abrasion resistance test reports, and material certification per drawing.
  • CLINs specify small production quantities, custom tooling, sample approvals, and acceptance sampling by lot or batch.
  • Evaluation requests shop capability for molding, casting, or pressing mineral products, references for custom refractory or abrasive manufacturing, and documented control of material traceability.
