UNSPSC 41141836: Zinc substrate

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

UNSPSC 41141836 Zinc substrate is a Commodity code that covers laboratory testing consumables and reagents, though recent state and local solicitations under this code tag a diverse range of diagnostic and research supplies that extend well beyond zinc-based products alone. State and local governments procure these materials for public health laboratories, environmental testing, food and water safety, wastewater surveillance, and clinical diagnostics. Issuing bodies include state health departments (Texas Health and Human Services Commission, Mississippi State Department of Health), county health authorities (Gwinnett County, Georgia), and academic medical centers (University of Texas Health Science Center at San Antonio). The scope reflects the actual buying patterns: Illumina and Clear Labs whole-genome-sequencing reagent bundles for pathogen detection; culture media and quality-control test kits from Biomerieux and Idexx for coliform and E. coli testing; chromatography columns, inlet seals, and chemical standards for drinking-water analysis; respiratory pathogen detection kits for wastewater surveillance; and general laboratory supplies including solid-phase extraction disks, saline solution, and Bioball bacterial strain kits. Contracts typically run one to two years with optional renewal periods and are competitively bid on an IFB or RFP basis, though some sole-source procurements occur when reagents are system-specific (Clear Labs, Illumina) or FDA-cleared for particular analytes (Idexx for coliform testing).

Recent activity concentrates in Texas and Mississippi, with scattered municipal procurement in Pennsylvania and Georgia. The Texas Health and Human Services Commission and its Department of State Health Services have issued multiple IFBs since April 2026 for laboratory consumables—HHS0017272 for respiratory pathogen detection kits (bid deadline May 19, 2026), HHS0017287 for Atlantic ReadyDisk HC-C18 solid-phase extraction disks (deadline May 13, 2026), HHS0017271 for gas chromatography columns and chemical standards (deadline May 12, 2026), and HHS0017881 for food and water testing supplies including zinc dust and Biomerieux kits (deadline August 26, 2026, historical value $25,000–$50,000). The Mississippi State Department of Health posted sole-source notices for Illumina sequencing reagents (objection deadline May 14, 2026, estimated cost $393,667.98) and Clear Labs whole-genome-sequencing kits (objection deadline May 14, 2026, estimated cost $226,072.00). Gwinnett County, Georgia issued RFQ BL144-26 for drug testing analyzer supplies (deadline October 14, 2026), and the University of Texas Health Science Center at San Antonio conducted an RFP for a comprehensive biotech research and clinical diagnostics catalog (deadline June 4, 2026, with 8,768 line items ordered in the prior year). The City of Philadelphia requested quotes for Clean Thru Extraction Columns as a micro-purchase (deadline May 30, 2026, $43,000 contract ceiling). All competitive awards are evaluated on best value rather than lowest price, and most Texas procurements require HUB Subcontracting Plans or encourage HUB participation.
