UNSPSC 51282531: Cefazolin benzathine

This classification denotes a cephalosporin antibiotic C16H20N2.C14H14N8O4S3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier BJN67HUZ04, chemically known as 5-thia-1-azabicyclo(4.2.0)oct-2-ene-2-carboxylic acid, 3-(((5-methyl-1,3,4-thiadiazol-2-yl)thio)methyl)-8-oxo-7-((1h-tetrazol-1-ylacetyl)amino)-, (6r-trans)-, compd. with n,n'-bis(phenylmethyl)-1,2-ethanediamine (2:1), but more generally known as cefazolin benzathine, which bears US NIH Compound Identifier 71300925.

Most nations, for tariff and trade purposes, schedule cefazolin benzathine under HS 29419000 and SITC 54139. As of Q4 2014, CEFAZOLIN BENZATHINE remains US FDA's Preferred Term for this commodity. SMILES: CC1NNC(S1)SCC2=C(N3[C@@H]([C@@H](C3=O)NC(=O)CN4CNNN4)SC2)C(=O)O.C1CCC(CC1)CNCCNCC2CCCCC2.

UNSPSC 51282531 Cefazolin benzathine is a Commodity code that in practice does not reflect the pharmaceutical products state and local governments are actively procuring under this classification. The recent opportunities tagged to this code show instead active solicitation for naloxone (an opioid antagonist) and safe drug deactivation systems, as well as past awards for doxycycline hyclate and ciprofloxacin hydrochloride—none of which are cefazolin benzathine or closely related products. The mismatch suggests that this code may be incorrectly applied in state and local procurement systems or that the tagging does not align with the actual pharmaceutical inventory being bought. The issuing bodies in the recent record include county health departments and state public health agencies procuring through cooperative purchasing arrangements (MMCAP Infuse consortium in one case) and direct competitive bidding in another.

Activity appears concentrated in the Southeast and Midwest, with recent opportunities from Illinois Department of Public Health and Seminole County, Florida. The Illinois Department of Public Health awarded a $2,999,999.11 pharmaceutical warehouse piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC on August 28, 2026, for a 12-month initial term with renewal options, sourced through an Invitation for Bid process. Seminole County, Florida issued an IFB on June 30, 2026, for 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries, though the response deadline shown (July 26, 2023) predates the posting date and appears to be a data error. The code shows limited recent procurement activity directly aligned with cefazolin benzathine; business development professionals should verify correct UNSPSC classification before pursuing opportunities tagged to this code.
