UNSPSC 41141523: Organic carbon standards

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

UNSPSC 41141523 Organic carbon standards (Commodity) covers certified reference materials and analytical reagents that state and local forensic laboratories, public health agencies, and law enforcement departments use for drug analysis, toxicology testing, and method validation. Recent solicitations show procurement of direct-ELISA immunoanalysis reagent kits for controlled-substance screening (cannabinoids, opiates, PCP, amphetamines, benzodiazepines, and others), DNA screening kits for forensic applications, and certified drug standards with ISO/IEC 17025 accreditation. State departments of public safety, criminal justice, and health and human services are the primary issuing bodies, along with county forensic laboratories and law enforcement agencies. The work involves supplying both reagent kits and certified reference materials that must meet strict purity and uncertainty tolerances for use in evidentiary analysis and analytical instrumentation validation.

Texas and Florida represent the most active recent markets. The Texas Department of Public Safety posted an IFB on July 9, 2026, due July 23, 2026, for 12 line items of direct-ELISA testing kits across multiple controlled substances (solicitation 40526R0008445A). The Texas Health and Human Services Commission solicited QIAxcel and QIAamp DNA screening kits on February 10, 2026 (IFB HHS0016902v2, due January 29, 2026), with historical pricing guidance of $25,050 to $30,000 annually. Pinellas County, Florida, in partnership with the Florida Department of Law Enforcement, issued Invitation to Quote 26-0305-ITQ on April 23, 2026, for 131 line items of certified drug standards funded through the Paul Coverdell Forensic Sciences Improvement Act Program with $49,034 allocated for equipment and supplies. Pinellas County extended small-business preference to certified SBEs, with priority consideration for submissions within the first five business days. The Illinois Department of Financial and Professional Regulation established a joint purchase master contract for mosquito testing equipment (RAMP System) in May 2026 as a sole-source procurement to ADAPCO, LLC. Contracts typically run one to two years with extension options, and vendors must provide supporting certifications, financial documentation, and compliance with federal and state statutory requirements including DEA licensing where controlled substances are involved.
