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, a Commodity code, nominally covers a specific antibiotic pharmaceutical product; however, the recent state and local opportunities tagged under this code show minimal direct relevance to erythromycin aspartate itself. The most recent solicitations capture pharmaceutical procurement by state health departments and county public-health entities, but they target unrelated drug products — antibiotics such as doxycycline and ciprofloxacin, and opioid-reversal and drug-deactivation supplies — rather than erythromycin aspartate specifically. State and local governments use this code tier to procure pharmaceuticals through consortium piggyback contracts, competitive IFBs, and direct-purchase arrangements with quarterly or annual delivery cadences, often bundled with compliance, insurance, and traceability requirements.

The Illinois Department of Public Health and Seminole County, Florida represent the issuing-body mix, reflecting state health departments and county health or emergency-services authorities as the primary buyers. The Illinois opportunity, posted August 28, 2026, was an IFB awarded to Chartwell Rx LLC for a $2,999,999.11 three-year pharmaceutical warehouse contract through the MMCAP Infuse consortium, closed to new bids. The Seminole County opportunity, posted June 30, 2026, sought 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to a county health building, response due July 26, 2023 — a misdated entry that appears to reference a prior fiscal cycle. No open solicitations for erythromycin aspartate itself appear in the recent records; vendors pursuing this code should treat current activity as limited and verify whether state pharmaceutical procurement offices are actively sourcing erythromycin aspartate through cooperative agreements, state contracts, or emergency stockpiling programs.
