UNSPSC 51284019: Chlortetracycline calcium

This classification denotes a tetracycline antibiotic C22H23ClN2O8.Ca, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier NR4B2SX17S, chemically known as 7-chloro-4-(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,6,10,12,12a-pentahydroxy-6-methyl-1,11-dioxo-2-naphthacenecarboxamide calcium salt, but more generally known as chlortetracycline calcium, which bears US NIH Compound Identifier 71458158. Most nations, for tariff and trade purposes, schedule chlortetracycline calcium under HS 29413000 and SITC 54133.

As of Q4 2014, CHLORTETRACYCLINE CALCIUM remains US FDA's Preferred Term for this commodity. Chlortetracycline calcium bears US NLM identifiers UMLS ID C2723846 and NCI Concept Code C80800. SMILES: C[C@]1(C2C(CCC(C2C(=O)C3=C([C@]4([C@@H](C[C@@H]31)[C@@H](C(=C(C4=O)C(=O)N)O)N(C)C)O)O)O)CL)O.[CA+2].

UNSPSC 51284019 Chlortetracycline calcium is a Commodity code, but the recent state and local opportunities posted under this classification do not reflect procurement of chlortetracycline calcium or veterinary pharmaceuticals. Instead, the tagged opportunities cover emergency medical supplies, naloxone and drug deactivation systems, direct-to-manufacturer pharmacy programs, and generic pharmaceuticals and OTC products for human health use. The code shows little relevant recent activity aligned with its nominal scope of a specific veterinary antibiotic compound.

The mismatch between the code's stated commodity and the opportunities classified under it suggests that state and local procurement offices may be using UNSPSC 51284019 as a catch-all for pharmaceutical and medical supply categories rather than as a precision taxonomy marker. The four recent solicitations span Seminole County, Florida (naloxone and drug deactivation systems); the Texas Health and Human Services Commission (direct-to-manufacturer prescription program planning); the City of Tampa (medical and first aid supplies for the Fire Department, an IFB with a March 13, 2026 response deadline and an estimated contract value of $700,000); and the Minnesota Multistate Cooperative Purchasing Alliance serving state and local government facilities across multiple states including Oregon (generic pharmaceuticals and OTC products, an RFP due March 26, 2026). The geographic spread extends across Florida, Texas, Minnesota, and Oregon, with cooperative purchasing vehicles present. Business development professionals should verify the correct UNSPSC code for chlortetracycline calcium procurement or monitor this code only if their focus is the broader pharmaceutical and medical supply market, where actual demand is evident but code classification is unreliable.
