UNSPSC 51283957: Sulfathiazole zinc

This classification denotes a sulfonamide anti-infective agent with the molecular formula 2C9H8N3O2S2.Zn, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4KCI0QUF9Q, chemically known as benzenesulfonamide, 4-amino-n-2-thiazolyl-, zinc salt, but more generally known as sulfathiazole zinc, which bears US NIH Compound Identifier 21571. European Medicines Agency schedules sulfathiazole zinc or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10731MIG.

Most nations, for tariff purposes, schedule sulfathiazole zinc under HS 29350090. SMILES: C1CC(CCC1N)S(=O)(=O)[N-]C2NCCS2.C1CC(CCC1N)S(=O)(=O)[N-]C2NCCS2.[ZN+2].

UNSPSC 51283957 Sulfathiazole zinc, a Commodity code, shows minimal recent state and local procurement activity aligned with its nominal scope. The two opportunities identified in the recent record are mismatched to the code: one involves antibiotic tablets (Doxycycline Hyclate and Ciprofloxacin Hydrochloride) procured through a pharmaceutical piggyback contract, and the other covers Naloxone and drug deactivation systems. Neither solicitation involves sulfathiazole zinc or products of equivalent chemical specificity. The tagging of these opportunities under this Commodity code appears to reflect either catalog-system classification misalignment or bundling of pharmaceutical purchases under a broad code rather than procurement of the specific active pharmaceutical ingredient or formulation the code nominally describes.

The Illinois Department of Public Health and Seminole County, Florida are the only issuing bodies represented in the recent record. The Illinois procurement, posted August 28, 2026, was an Invitation for Bid through the MMCAP Infuse consortium cooperative purchasing vehicle, with award already completed to Chartwell Rx LLC at $2,999,999.11 over the contract life. The Seminole County opportunity, posted June 30, 2026, was an IFB with a response deadline of July 26, 2023 (a historical closing date that post-dates the posting, indicating a data anomaly in the source). Given the absence of open solicitations directly targeting sulfathiazole zinc and the mismatch between the code's scope and the opportunities tagged to it, this code does not represent actionable current procurement activity for vendors in this product category.
