UNSPSC 41141815: Iron substrate

In this classification, this entry connotes a substrate made of Iron that is used in clinical chemistry testing.

UNSPSC 41141815 Iron substrate is a Commodity code that state and local health agencies procure as laboratory consumables, reagents, and analytical supplies supporting diagnostic testing and environmental surveillance. Recent solicitations show the code tagged to specialized research materials including next-generation sequencing consumables, culture media kits, solid-phase extraction disks, chromatography columns, and chemical standards used in food safety, water quality, and infectious disease testing. The issuing-body mix is dominated by state health departments and their constituent laboratories—Texas Health and Human Services Commission, Mississippi State Department of Health, and the University of Texas Health Science Center at San Antonio all post under this code—though city governments and special-purpose entities appear minimally. The work itself spans routine laboratory supply replenishment for public health surveillance (pathogen detection, foodborne illness screening, drinking water compliance testing) and specialized diagnostic reagent supply agreements designed for single-instrument platforms that preclude vendor substitution.

Activity clusters heavily in Texas, with the majority of recent opportunities issued by HHSC and DSHS between February and June 2026. Mississippi State Department of Health posted sole-source procurements for whole genome sequencing reagents (Clear Labs and Illumina kits totaling $619,740 combined) in April 2026, while the State of California and City of Philadelphia each posted single opportunities for mycobacterial diagnostic reagents and extraction equipment respectively. Representative recent solicitations include Texas HHSC HHS0017272 (Invitation for Bids, respiratory pathogen detection kits for wastewater surveillance, due May 19, 2026), HHS0017287 (solid-phase extraction disks for EPA drinking water methods, due May 13, 2026), and HHS0017271 (standards and consumables for organic chemistry testing, due May 12, 2026)—all competitive IFBs with firm-fixed-price requirements and historical spend guidance in the $25,000–$90,000 range. The University of Texas Health Science Center at San Antonio's RFP 745-26-P19 (biotech research and clinical diagnostics catalog supplier, due June 4, 2026) establishes a longer-term framework with Jaggaer e-procurement integration and tiered MSRP discounts across product categories. Set-asides and certifications vary; Texas procurements emphasize HHS Solicitation Affirmations and tax/compliance compliance, while California opportunities reference Certified Business Enterprise (CBE) set-aside consideration and the University of Texas mandates Historically Underutilized Business (HUB) Subcontracting Plans.
