UNSPSC 51371508: Tilidine fumarate

This classification denotes an opioid analgesic, narcotic, and cyclohexanecarboxylic acid with the molecular formula C17H23NO2.C4H4O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier DXT828600R, chemically known as 3-cyclohexene-1-carboxylic acid, 2-(dimethylamino)-1-phenyl-, ethyl ester, trans-(+/-)-, (e)-2-butenedioate (1:1), but more generally known as tilidine fumarate, which bears US NIH Compound Identifier 5284464.

European Medicines Agency schedules tilidine fumarate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB11051MIG. Most nations, for tariff purposes, schedule tilidine fumarate under HS 29224400. SMILES: CCOC(=O)[C@]1(CCC=C[C@@H]1N(C)C)C2CCCCC2.C(=C/C(=O)O)\C(=O)O.

UNSPSC 51371508 Tilidine fumarate, a Commodity code, shows limited direct recent activity in state and local procurement. The three most recent opportunities tagged to this code involve naloxone and safe drug deactivation systems, direct-to-manufacturer pharmacy initiatives, and generic multi-source pharmaceuticals and OTC products—none of which directly corresponds to tilidine fumarate, an opioid analgesic. The mismatch suggests that state and local issuing bodies are either tagging broader pharmaceutical procurement efforts under this code or that tilidine fumarate itself does not drive standalone solicitations at the state and local level. When pharmaceutical products are procured under related codes, the work typically involves competitive bidding for standardized drug supplies, compliance with FDA and DEA requirements, pricing tied to authorized wholesaler relationships, and delivery schedules tied to public health facilities or health departments.

The issuing bodies in the recent record include Seminole County, Florida (health department procurement); the Texas Health and Human Services Commission (state-level RFI for pharmacy benefit programs); and the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP, a state cooperative vehicle serving multiple jurisdictions including Oregon). Geographic activity centers on Florida, Texas, and the upper Midwest, with the cooperative structure suggesting broader participation across multiple states. The Seminole County IFB (Solicitation IFB60459723LAS, due July 26, 2023) sought 1,900 units of naloxone annually; the Texas HHS RFI (HHS0017013, posted April 3, 2026) explored direct-to-manufacturer pharmacy contracting; and the MMCAP RFP (S1070000015802, due March 26, 2026) established statewide contracts for generic pharmaceuticals across authorized wholesalers. None of these opportunities explicitly names tilidine fumarate or opioid analgesics as a procurement focus, indicating that this Commodity code sees minimal targeted state and local activity.
