UNSPSC 41141529: Silica standards

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

UNSPSC 41141529 Silica standards, a Commodity code, covers laboratory reference materials and quality-control standards used by state and local public health, environmental, and forensic agencies to validate analytical instruments and analyze samples for regulatory compliance. State and local governments buy certified reference materials—drug standards, immunoassay reagents, radon measurement standards, and specialized consumables—through this code to support environmental testing, food and water safety, toxicology analysis, and substance-testing operations. The issuing bodies include state health departments, state public safety agencies, county forensic laboratories, and county environmental offices; Texas Health and Human Services Commission and the Texas Department of Public Safety appear multiple times in recent solicitations, indicating they are regular buyers of standards and reference materials.

Recent activity is concentrated in Texas and Florida. The Texas Health and Human Services Commission solicited standards, consumables, and instrument parts for drinking water analysis (IFB HHS0018026, due October 9, 2026) and lab supplies for food, water, dairy, and shellfish testing (IFB HHS0017881, due August 26, 2026), with historical fiscal-year spending of $25,000 to $75,000 per contract; the Texas Department of Public Safety solicited immunoassay reagent kits for substance analysis (IFB 405-26R0008445A, due July 23, 2026). Pinellas County, Florida, procured certified drug standards for forensic laboratory validation and evidence analysis (ITQ 26-0305-ITQ, due April 23, 2026), with approximately $49,034.00 in federal funding allocated to standards and equipment. Rockland County, New York, sought proposals for radon measurement devices and laboratory analysis services (RFP RFBRC2026044, due August 20, 2026). Illinois established a master contract for mosquito testing equipment through a sole-source procurement to ADAPCO, LLC (notice posted May 4, 2026). Delivery typically occurs within 30 to 60 days of award, and contract terms run one to two years with optional extensions at the issuing body's discretion.
