UNSPSC 11101531: Serpentine

Any of a group of hydrous magnesium-rich silicate minerals. The composition of these common rock-forming minerals approximates Mg3Si2O5 OH 4. Serpentine is usually grayish, white, or green but may be yellow -chrysotile- or green-blue -antigorite. The green color is due to iron replacing magnesium.

UNSPSC 11101531 Serpentine, a Commodity code, does not reflect the actual procurement activity tagged to it in recent state and local solicitations. The code nominally covers a geological material (serpentine), yet the recent opportunities posted under this code involve structural metals (aluminum, iron, rebar, and steel), law enforcement equipment, and irrigation system installation—none of which relate to serpentine sourcing or supply. This mismatch suggests either a systematic tagging error in the source database or that the code is being misapplied to capture broader categories of goods and services. State and local procurement offices typically use UNSPSC codes to route opportunities to relevant vendor communities, and the divergence here is significant enough that pursuing opportunities under this code based on its nominal definition would be misleading.

The recent opportunities block shows no substantive activity aligned with serpentine as a commodity. The City of Fort Worth's RFP 26-0222 (due July 23, 2026) seeks structural metals on a non-exclusive, as-needed basis with a 30 percent small business participation goal and a preference for vendors located within five Texas counties; Sourcewell's RFP #061626 (due June 16, 2026) is a cooperative purchasing vehicle for law enforcement equipment across multiple jurisdictions; and the City of DeBary's Bid 03-15 (posted April 2026, with a due date of April 10, 2015—an apparent data error) involves irrigation system conversion. None of these solicitations describe serpentine procurement, and the code shows no relevant recent state or local contract opportunities.
