UNSPSC 51282313: Erythromycin aspartate

This classification denotes a macrolide antibiotic with the molecular formula C37H67NO13.C4H7NO4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier DA04YX38DA, chemically known as aspartic acid, l-, compd. with erythromycin (1:1), but more generally known as erythromycin aspartate, which bears US NIH Compound Identifier 83953. European Medicines Agency schedules erythromycin aspartate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06605MIG.

Most nations, for tariff purposes, schedule erythromycin aspartate under HS 29415000. SMILES: CC[C@@H]1[C@@]([C@@H]([C@H](C(=O)[C@@H](C[C@@]([C@@H]([C@H]([C@@H]([C@H](C(=O)O1)C)O[C@H]2C[C@@]([C@H]([C@@H](O2)C)O)(C)OC)C)O[C@H]3[C@@H]([C@H](C[C@H](O3)C)N(C)C)O)(C)O)C)C)O)(C)O.C([C@@H](C(=O)O)N)C(=O)O.

UNSPSC 51282313 Erythromycin aspartate is a Commodity code that does not align with the actual work being solicited under it in state and local procurement. Recent opportunities tagged to this code involve naloxone and drug deactivation systems, therapeutic pharmacy initiatives, medical and first aid supplies for emergency response, and generic multi-source pharmaceuticals and OTC products—none of which target erythromycin aspartate specifically. The code shows material misalignment between its nominal scope (a single macrolide antibiotic) and the broad pharmaceutical procurement activity actually appearing in state and local notices.

The issuing bodies span state agencies, counties, and cities: the Texas Health and Human Services Commission, Seminole County Florida, the Minnesota Department of Administration (acting through the multistate cooperative purchasing vehicle MMCAP), and the City of Tampa. Geographic activity includes Florida, Texas, and Minnesota, with MMCAP extending to Oregon. Representative recent opportunities include the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) RFP for generic multi-source pharmaceuticals and OTC products (S1070000015802, due March 26, 2026), the City of Tampa IFB for medical and first aid supplies for the Fire Department Rescue Division (26P00145, due March 13, 2026, with an estimated contract value of $700,000.00), Seminole County's IFB for naloxone and drug deactivation systems (IFB60459723LAS, due July 26, 2023), and the Texas HHS RFI for direct-to-manufacturer prescription programs (HHS0017013, posted April 3, 2026). The mismatch between code scope and actual procurement activity suggests either a tagging error or that erythromycin aspartate operates within a broader pharmaceutical supply contract structure—neither interpretation supports this code as a standalone pursuit signal for business development.
