UNSPSC 51283956: Sulfathiazole sodium monohydrate

This classification denotes a sulfonamide anti-infective agent with the molecular formula C9H8N3O2S2.Na.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier W6NDW4K12P, chemically known as benzenesulfonamide, 4-amino-n-2-thiazolyl-, sodium salt, hydrate (1:1:1), but more generally known as sulfathiazole sodium monohydrate, which bears US NIH Compound Identifier 24975.

European Medicines Agency schedules sulfathiazole sodium monohydrate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10731MIG. Most nations, for tariff purposes, schedule sulfathiazole sodium monohydrate under HS 29350090. SMILES: C1CC(CCC1N)S(=O)(=O)[N-]C2NCCS2.O.[NA+].

UNSPSC 51283956 Sulfathiazole sodium monohydrate is a Commodity code that shows minimal direct alignment with recent state and local procurement activity. The code nominally identifies a specific pharmaceutical ingredient, yet the recent solicitations tagged under this code involve procurement of finished pharmaceutical products and medical supplies — naloxone, drug deactivation systems, medical first-aid supplies, and generic multi-source pharmaceuticals — rather than active pharmaceutical ingredients like sulfathiazole sodium monohydrate. The scope mismatch suggests that either the code is being applied inconsistently by issuing bodies or the commodity itself appears only as a component ingredient in finished formulations being purchased, rather than as a standalone procurement category.

The issuing bodies across recent opportunities span county health departments (Seminole County, Florida), state health agencies (Texas Health and Human Services Commission), municipal fire departments (City of Tampa), and cooperative purchasing alliances serving multiple states (Minnesota Multistate Cooperative Purchasing Alliance). Geographic activity is concentrated in Florida, Texas, Minnesota, and Oregon, with representation across health departments, emergency response services, and statewide procurement vehicles. Representative recent opportunities include Seminole County's IFB 60459723LAS for naloxone and drug deactivation systems (1,900 units of naloxone and 800 deactivation systems annually, due July 26, 2023), the City of Tampa's IFB 26P00145 for medical and first aid supplies serving the Fire Department Rescue Division (169 line items, estimated contract value $700,000, due March 13, 2026), and the Minnesota Multistate Cooperative Purchasing Alliance's RFP S1070000015802 for generic multi-source pharmaceuticals and OTC products distributed across state and local facilities (proposals due March 26, 2026). The code warrants careful review to confirm whether sulfathiazole sodium monohydrate is actually being purchased as a standalone ingredient or whether tagging reflects vendor categorization systems that do not align with UNSPSC intent.
