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 is a Commodity code that shows limited recent state and local procurement activity aligned with its nominal scope. The code's abstract product definition—a topical antiseptic and antimicrobial compound—does not match the substances actually being solicited under this code tag in recent state and local opportunities. Recent opportunities tagged to this code involve naloxone (an opioid antagonist), pharmaceutical wholesaling and direct-to-manufacturer prescription programs, and emergency medical and first aid supplies, none of which are sulfathiazole zinc or closely related topical antimicrobials. This mismatch suggests either miscoding by the issuing jurisdictions or that the code has drifted from its primary use in current state and local procurement.

The issuing bodies in the recent-opportunities block span a mix of county health authorities, state health agencies, municipal fire departments, and cooperative purchasing alliances. Seminole County, Florida (IFB 60459723LAS, response due July 26, 2023) solicited naloxone and drug deactivation systems; the City of Tampa (IFB 26P00145, response due March 13, 2026) sought medical and first aid supplies for its Fire Department Rescue Division under a sheltered-market contract estimated at $700,000 reserved for certified Small Local Business Enterprises; the Texas Health and Human Services Commission (RFI HHS0017013, posted April 3, 2026) gathered market intelligence on direct-to-manufacturer prescription programs; and the Minnesota Multistate Cooperative Purchasing Alliance (RFP S1070000015802, response due March 26, 2026) established multi-state contracts for generic pharmaceuticals and OTC products distributed through AmerisourceBergen, Cardinal Health, and Morris & Dickson. Because the recent opportunities are not substantively related to sulfathiazole zinc, this code presents limited opportunity for vendors in the antimicrobial topical-compound space.
