UNSPSC 51284716: Tiamulin hydrogen 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.

Most nations, for tariff and trade purposes, schedule tiamulin hydrogen fumarate under HS 29419000. SMILES: CCN(CC)CCSCC(=O)O[C@@H]1C[C@@]([C@H]([C@@H]([C@@]23CC[C@H]([C@@]1([C@@H]2C(=O)CC3)C)C)C)O)(C)C=C.C(=C/C(=O)O)\C(=O)O.

UNSPSC 51284716 Tiamulin hydrogen fumarate is a Commodity code for a veterinary antimicrobial pharmaceutical product. The recent state and local opportunities tagged to this code do not reflect procurement of tiamulin hydrogen fumarate itself; instead, they document purchases of human-use pharmaceuticals (Doxycycline Hyclate, Ciprofloxacin Hydrochloride) and public health supplies (Naloxone, drug deactivation systems). The code shows little relevant recent activity aligned with its nominal scope. State and local buyers do source animal health and veterinary pharmaceutical products through piggyback and direct-award arrangements, typically via county health departments, state veterinary agencies, and public health authorities managing disease control or animal welfare programs, but the opportunities currently tagged to this code reflect a classification mismatch rather than active tiamulin procurement.

The two most recent opportunities posted under this code—the Illinois Department of Public Health's $2,999,999.11 piggyback award to Chartwell Rx LLC (completed August 28, 2026) and Seminole County, Florida's invitation for bid for Naloxone and drug deactivation systems (posted June 30, 2026, due July 26, 2026)—are both human pharmaceutical and public health supplies procurements and do not represent the animal antimicrobial scope the code nominally covers. A business development professional evaluating this code should verify with issuing bodies whether tiamulin or related veterinary antimicrobials are actually being solicited under different codes or through cooperative purchasing vehicles, as the current tagging does not surface genuine demand in this commodity area.
