UNSPSC 41141533: Thiosulfate standards

In this classification, this entry connotes a standardized formulation of Thiosulfate used to conduct Anion tests.

UNSPSC 41141533 Thiosulfate standards is a Commodity-tier code with minimal recent state and local procurement activity aligned to its nominal scope. The recent opportunities tagged to this code—immunoassay reagent kits for drug testing, mosquito-borne-illness detection equipment, forensic drug reference standards, mass spectrometry equipment, and DNA screening kits—are tangential or unrelated to thiosulfate chemical standards. The Texas Department of Public Safety's July 2026 IFB for Direct ELISA testing kits and the Pinellas County, Florida procurement of certified reference materials for forensic drug analysis represent the closest activity to chemical standards procurement, but neither explicitly solicits thiosulfate products or chemical reagent standards as the primary scope. The Illinois Department of Financial and Professional Regulation's May 2026 mosquito testing equipment notice and the Texas Health and Human Services Commission's DNA screening kit procurement represent specialized analytical equipment rather than chemical standards.

Activity is concentrated in Texas and Florida, with isolated procurement from Illinois. The Texas Department of Public Safety (July 23, 2026 IFB response date), Pinellas County in partnership with the Florida Department of Law Enforcement (April 23, 2026 ITQ response date with $72,126.85 federal funding), and Texas HHSC (January 29, 2026 IFB response date, $25,050–$30,000 historical spend range) are the named repeat issuers in the forensic and clinical laboratory testing space. No recent opportunities explicitly solicit thiosulfate standards or general-purpose chemical reference materials from state and local buyers. The code shows little relevant recent activity in the traditional state and local procurement market; consider whether the underlying source data reflects a systematic misclassification or whether thiosulfate standards procurement by state and local buyers occurs through standing cooperative agreements or vendor catalogs outside formal solicitation channels.
