UNSPSC 41141516: Inorganic carbon standards

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

UNSPSC 41141516 Inorganic carbon standards (Commodity) encompasses certified reference materials and testing reagents for forensic drug analysis, toxicology screening, and laboratory method validation. State and local governments procure these materials under the code to support crime labs, public health agencies, and forensic operations requiring ISO/IEC 17025–accredited standards with documented purity and expanded uncertainty specifications. Recent solicitations show procurement of direct ELISA testing kits for substance detection, West Nile Virus and dengue test kits, and certified drug reference materials ranging from controlled substances to novel analytes, all accompanied by certificates of analysis. Issuing bodies include state law enforcement departments, county forensic laboratories, state health and human services commissions, and public safety agencies, often in partnership with state forensic oversight entities or federal grant administrators.

Recent activity concentrates in Texas and Florida. The Texas Department of Public Safety issued IFB 405-26R0008445A (due July 23, 2026) for direct ELISA testing kits supporting cannabinoid, opioid, and amphetamine analysis across 12 line items. Pinellas County, Florida, in partnership with the Florida Department of Law Enforcement, released Invitation to Quote 26-0305-ITQ (due April 23, 2026) for 131 line items of certified drug standards meeting ISO 17034:2016 accreditation, funded in part through a $72,126.85 Paul Coverdell Forensic Sciences Improvement Act grant with approximately $49,034.00 designated for supplies procurement. The Illinois Department of Financial and Professional Regulation's Centralized Maintenance Services posted a joint purchase master contract (notice of intent May 4, 2026) for West Nile Virus and dengue test kits through a sole-source award to ADAPCO. The Texas Health and Human Services Commission issued competitive IFB HHS0016902v2 (due January 29, 2026) for QIAxcel DNA screening kits supporting routine forensic DNA applications, with historical annual volumes of $25,050 to $30,000.
