UNSPSC 11101521: Silicon carbide

UNSPSC 11101521 Silicon carbide is a Commodity code that nominally addresses raw silicon carbide materials, but recent state and local opportunities show minimal alignment with this taxonomy classification. The four posted solicitations span irrigation system components (City of DeBary), snowplow cutting edges and hardware (Draper City), structural metals and steel (City of Fort Worth), and law enforcement equipment (Sourcewell cooperative). Only the Draper City snowplow bid explicitly names carbide products—specifically carbide snowplow cutting edges in 4' × 6" and 3' × 6" models and Blockbuster segmented systems—as part of a broader winter road maintenance supply contract. The remaining opportunities (irrigation improvements, structural metals, and law enforcement equipment) do not involve silicon carbide procurement and appear to have been tagged to this code in error.

State and local activity under this code shows no consistent issuing-body pattern or geographic concentration. The Draper City snowplow IFB (due October 16, 2026) represents the only recent opportunity where carbide material is actually being procured; Draper City retained options for up to four additional one-year renewals with potential price adjustments capped at the lesser of annual CPI change (Western Region) or 3 percent. The City of Fort Worth RFP 26-0222 (closed July 23, 2026) sought aluminum, iron, rebar, and steel on an as-needed basis under a small-business participation goal of 30 percent. Geographic spread across the recent block includes Utah, Florida, Texas, and Washington state, but only the Utah opportunity involves silicon carbide. The code currently shows little relevant recent activity and warrants review against the actual commodity taxonomy, as the recent postings suggest misclassification or portfolio drift rather than sustained state and local demand for silicon carbide materials.
