UNSPSC 11101527: Diatomaceous silica

UNSPSC 11101527 Diatomaceous silica is a Commodity code that shows minimal relevant recent procurement activity at the state and local level. The code nominally covers diatomaceous earth and related silica products used in filtration, abrasives, and industrial applications, yet the three most recent opportunities posted under this code involve structural steel and metals (Fort Worth), law enforcement equipment (Sourcewell cooperative), and park irrigation system installation (DeBary, Florida) — none of which align with diatomaceous silica procurement. State and local procurement offices appear to be using this code incorrectly or as a default classification for unrelated goods and services.

The geographic spread of these misaligned opportunities spans Texas, Washington, Minnesota, and Florida, with no concentrated activity pattern. The Fort Worth RFP (posted June 24, 2026, due July 23, 2026) is the only opportunity with substantive scope detail, but it targets aluminum, iron, rebar, and steel materials on an as-needed basis with a 30 percent small business participation goal for certified firms in Tarrant, Wise, Johnson, Parker, or Denton County — a commodity unrelated to diatomaceous silica. Absence of recent state and local solicitations actually seeking diatomaceous silica products suggests either minimal procurement demand under this code or systematic miscoding. Firms pursuing this code should monitor whether activity patterns shift or clarify whether posting entities are using UNSPSC classifications that reflect actual purchasing needs.
