NIGP 59590: Vermiculite and Perlite

NIGP 59590 Vermiculite and Perlite, an Item code, classifies mineral aggregates and soil amendments that state and local governments procure for construction, landscaping, horticulture, and infrastructure projects. Based on recent solicitation activity, the code captures lightweight porous minerals used in insulation, potting media, athletic field construction, and specialized fill applications where thermal or drainage properties matter.

The recent opportunity record shows DeKalb County, Georgia posting an ITB on June 9, 2026 (PE64400NONST2026000000260, due July 13, 2026) for reconstruction of the DeKalb Tennis Center in Mason Mill Park, Decatur, which includes site work, a new pro shop building, and complete IT and low-voltage infrastructure installation. The scope encompasses labor, materials, equipment, supervision, testing, and certifications for a fully operational system. County governments, municipalities, school districts, and special-purpose authorities managing parks, athletic facilities, and grounds maintenance represent the typical issuing bodies under this code. Geographic activity appears concentrated in the Southeast, with DeKalb County a visible recent buyer. The limited recent-opportunity record reflects the specialized and cyclical nature of vermiculite and perlite procurement — these materials are typically bundled into larger construction or grounds-maintenance contracts rather than solicited as standalone commodity purchases, making standalone opportunities sparse in the state and local market.
