UNSPSC 51284611: Imipenem anhydrous

This classification denotes a beta-lactam antibiotic with the molecular formula C12H17N3O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Q20IM7HE75, chemically known as 1-azabicyclo(3.2.0)hept-2-ene-2-carboxylic acid, 6-(1-hydroxyethyl)-3-((2-((iminomethyl)amino)ethyl)thio)-7-oxo-, (5r-(5.alpha.,6.alpha.(r*)))-, but more generally known as imipenem anhydrous, which bears US NIH Compound Identifier 47317.

European Medicines Agency schedules imipenem anhydrous or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08151MIG. Most nations, for tariff purposes, schedule imipenem anhydrous under HS 29419000. SMILES: C[C@H]([C@@H]1[C@H]2CC(=C(N2C1=O)C(=O)O)SCCNC=N)O.

UNSPSC 51284611 Imipenem anhydrous is a Commodity code that nominally identifies a specific beta-lactam antibiotic active pharmaceutical ingredient, but recent state and local procurement activity under this code shows little alignment with the code's named scope. The recent opportunities tagged to this code cover medical and first aid supplies procurement (including respiratory equipment, cardiac monitoring electrodes, endotracheal tubes, and bandaging materials for emergency responders), naloxone and drug deactivation systems for community health, generic multi-source pharmaceuticals and over-the-counter products through cooperative purchasing, and exploratory market intelligence on direct-to-manufacturer prescription programs. The issuing bodies include county health departments (Seminole County, Florida), municipal fire departments and purchasing offices (City of Tampa), state health and human services agencies (Texas HHS Commission), and statewide cooperative purchasing consortia (Minnesota Multistate Cooperative Purchasing Alliance serving multiple states including Oregon). The code shows activity across health department procurement, emergency response supply acquisition, and pharmacy benefit program contracting rather than focused procurement of a single pharmaceutical ingredient.

Geographic activity appears concentrated in the Southeast and Upper Midwest, with recent solicitations from Florida, Texas, and Minnesota. Representative recent opportunities include Seminole County's IFB 60459723LAS (posted June 30, 2026, due July 26, 2023) for naloxone and safe drug deactivation systems with annual delivery of 1,900 units of naloxone and 800 deactivation systems; the City of Tampa's sealed-bid solicitation 26P00145 (due March 13, 2026) for medical and first aid supplies totaling an estimated $700,000 with a certified Small Local Business Enterprise set-aside and 5 percent bid discount; and the Minnesota Multistate Cooperative Purchasing Alliance's RFP S1070000015802 (due March 26, 2026) for generic multi-source pharmaceuticals and OTC products through three authorized wholesalers with a two-year initial contract term. The code displays minimal recent activity directly tied to imipenem anhydrous procurement, suggesting either miscoding of these opportunities or low state and local demand for this specific active pharmaceutical ingredient through formal competitive procurement channels.
