UNSPSC 51201827: Levamisole hydrochloride

This classification denotes a chemo immunostimulant adjuvant with the molecular formula C11H12N2S.ClH, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier DL9055K809, chemically known as 2,3,5,6-tetrahydro-6-phenyl-imidazo(2,1-b)thiazole but more generally known as levamisole hydrochloride, which bears US NIH Compound Identifier 3913. European Medicines Agency schedules Levamisole hydrochloride in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB02902MIG.

Most nations, for tariff and trade purposes, schedule levamisole hydrochloride under HS 29349990. As of Q4 2014, LEVAMISOLE HYDROCHLORIDE remains US FDA's Preferred Term for this commodity. Levamisole hydrochloride bears US NLM identifiers UMLS ID C0733384 and NCI Concept Code C610. SMILES: C1CCC(CC1)[C@H]2CN3CCSC3=N2.CL.

UNSPSC 51201827 Levamisole hydrochloride is a Commodity code nominally covering a specific pharmaceutical agent, but the recent state and local procurement activity under this code shows no alignment with that chemical classification. The single recent opportunity posted under the code is a sole source notice from the Mississippi State Department of Health for Yellow Fever Vaccine from Sanofi Pasteur, Inc., a vaccine product that falls outside the levamisole hydrochloride scope. This mismatch suggests either a tagging error in the state procurement system or that the code is not actively used for its stated commodity in state and local contracting. State health departments are the primary issuing bodies visible in the recent record, though the single opportunity provides limited basis for characterizing the issuing-body mix or geographic concentration.

The Mississippi State Department of Health posted a notice of proposed sole source purchase on July 13, 2026, with an objection deadline of August 3, 2026 at 10:00 a.m. CST; submissions should be directed to Cynthia Brasher at Cynthia.brasher@msdh.ms.gov. The notice does not specify quantity, contract term, estimated value, or pricing. The code shows minimal recent activity relevant to levamisole hydrochloride procurement in state and local markets; if your firm pursues vaccines or pharmaceutical procurement, focus on health department RFPs and sole source notices directly rather than relying on this particular UNSPSC classification to surface relevant opportunities.
