UNSPSC 11101525: Kieserite

UNSPSC 11101525 Kieserite is a Commodity code nominally designating magnesium sulfate minerals, yet recent state and local opportunities tagged with this code show minimal alignment with the category's abstract scope. The three most recent opportunities involve irrigation system installation and controller upgrades, structural metals procurement (aluminum, iron, rebar, and steel), and law enforcement equipment — none of which involve kieserite or related mineral products. The code exhibits little relevant recent activity in state and local procurement, suggesting either broad miscategorization in source databases or inactive market demand for magnesium sulfate products through traditional government contracting channels.

The issuing bodies in the recent-opportunity set span city procurement offices (City of DeBary, Florida; City of Fort Worth, Texas) and cooperative purchasing vehicles (Sourcewell serving multiple Washington counties and national public entities), reflecting typical municipal and regional structures. Geographic activity appears concentrated in Florida and Texas with cooperative-purchasing reach into Washington state and nationally, though the opportunities themselves do not substantiate kieserite procurement. The City of DeBary's Rob Sullivan Park Irrigation Improvements (Bid 03-15, response deadline April 10, 2015) and the City of Fort Worth's RFP for aluminum, iron, rebar, and steel (RFP 26-0222, due July 23, 2026) represent the most recent fiscal-year postings, neither of which align with mineral commodities. Vendors pursuing this code should verify the actual commodity requirements in solicitation documents before responding, as the UNSPSC classification does not reliably signal the work being solicited.
