UNSPSC 41105329: Blocking agents

UNSPSC 41105329 Blocking agents is a Commodity code representing specialized chemical reagents and laboratory consumables purchased by state and local governments for forensic, DNA analysis, and drug-screening applications. State and local buyers under this code procure branded laboratory supplies including genetic analyzer components, buffer solutions, polymers, sequencing kits, DNA standards, and immunoassay reagents for detection of controlled substances—products typically sourced from established manufacturers such as Thermo Fisher Scientific (Life Technologies), Promega, Qiagen, Abbott (Immunalysis), and ANDE Corporation. Issuing bodies are primarily state law-enforcement and natural-resources agencies operating crime laboratories and forensic analysis facilities; the Texas Comptroller of Public Accounts Statewide Procurement Division acts as the centralized buying agent for multiple state departments on cooperative purchasing vehicles.

Texas is the primary jurisdiction showing recent activity under this code. The Texas Comptroller of Public Accounts Statewide Procurement Division posted IFB 304T-27-175A1.1 on September 23, 2026, soliciting proprietary chemical laboratory equipment and supplies for the Texas Department of Public Safety and Texas Department of Parks and Wildlife, with a bid due date of October 20, 2026. The solicitation covers 50 line items of specialized forensic reagents and consumables with single-source or brand/SKU specifications, expected contract value spanning multiple years of statewide delivery with quantities ranging from 8 to 5,000 units per item based on four-year historical usage. The initial term runs through October 31, 2027, with three one-year renewal options at the discretion of the Comptroller's office.
