UNSPSC 51422352: Melengestrol acetate

This classification denotes a therapeutic progestin with the molecular formula C25H32O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4W5HDS3936, chemically known as 17-hydroxy-6-methyl-16-methylenepregna-4,6-diene-3,20-dione acetate but more generally known as melengestrol acetate, which bears US NIH Compound Identifier 18020. Most nations, for tariff and trade purposes, schedule melengestrol acetate under HS 29372300 and SITC 54153. As of Q4 2014, MELENGESTROL ACETATE remains US FDA's Preferred Term for this commodity.

Melengestrol acetate bears US NLM identifiers UMLS ID C0025223 and NCI Concept Code C74577. SMILES: CC1=C[C@@H]2[C@H](CC[C@]3([C@H]2CC(=C)[C@@]3(C(=O)C)OC(=O)C)C)[C@@]4(C1=CC(=O)CC4)C.

UNSPSC 51422352 Melengestrol acetate is a Commodity code that appears to show minimal alignment with recent state and local procurement activity. The code nominally describes a livestock growth promotant used in animal agriculture, yet the recent opportunities posted under this code involve the procurement of naloxone (an opioid antagonist) and safe drug deactivation systems for community health, as well as information-gathering on direct-to-manufacturer prescription programs — neither of which relates to melengestrol acetate or animal feed additives. This mismatch suggests either a cataloging error in the underlying state and local procurement systems or that the code is not actively used for its intended commodity scope in current state and local contracting.

The two opportunities on record are Seminole County, Florida's IFB for naloxone and drug deactivation systems (posted June 30, 2026, with a response deadline of July 26, 2023) and the Texas Health and Human Services Commission's RFI on direct-to-manufacturer prescription programs (posted April 3, 2026). Neither opportunity reflects livestock production inputs or the agricultural pharmaceutical products the code nominally covers. No relevant state and local solicitations for melengestrol acetate itself appear in the recent-opportunities block, indicating that this code either sees no current demand in state and local government procurement or is not the mechanism through which such demand is tagged and tracked.
