UNSPSC 51284715: Tiamulin fumarate

This classification denotes an antibiotic with the molecular formula C28H47NO4S.C4H4O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier ION1Q02ZCX, chemically known as acetic acid, ((2-(diethylamino)ethyl)thio)-, 6-ethenyldecahydro-5-hydroxy-4,6,9,10-tetramethyl-1-oxo-3-alpha,9-propano-3-alpha-h-cyclopentacycloocten-8-yl ester, (e)-2-butenedioate (1:1) (salt) but more generally known as tiamulin fumarate, which bears US NIH Compound Identifier 6434500.

UNSPSC 51284715 Tiamulin fumarate is a Commodity code that nominally designates an animal-health pharmaceutical; however, recent state and local activity shows misalignment with this scope. The opportunities posted under this code involve human pharmaceutical procurement — naloxone (opioid-reversal medication), generic multi-source pharmaceuticals and over-the-counter products, and direct-to-manufacturer prescription fulfillment — rather than veterinary antimicrobials. The issuing bodies span state health and human services agencies (Texas HHS Commission, Minnesota Department of Administration), county government (Seminole County, Florida), and city fire and emergency-response departments (Tampa Fire Department). The procurement vehicles range from cooperative purchasing arrangements (MMCAP) to competitive bids and requests for information, indicating a mix of standing agreements and ad hoc acquisition.

Geographic activity concentrates in Florida, Texas, and Minnesota based on recent postings. Representative opportunities include Seminole County's IFB60459723LAS, posted June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to Sanford, Florida and a response deadline of July 26, 2023 (note: posted date appears inconsistent with deadline year); the City of Tampa's IFB 26P00145, posted March 25, 2026, for 169 line items of medical and first aid supplies for the Tampa Fire Department Rescue Division with an estimated contract value of $700,000.00 and a sealed-bid deadline of March 13, 2026; and the Minnesota Department of Administration's MMCAP RFP S1070000015802, posted January 20, 2026, for generic multi-source pharmaceuticals and OTC products with a proposal deadline of March 26, 2026 and contract effectiveness of July 1, 2026. The Texas HHS Commission's RFI HHS0017013, posted April 3, 2026, represents exploratory procurement for a Therapeutic Pharmacy Initiative direct-to-manufacturer program. The code shows material misclassification — none of the recent opportunities align with tiamulin fumarate's veterinary-pharmaceutical purpose, suggesting either persistent taxonomic error in source data or misapplication of the code by participating jurisdictions.
