UNSPSC 51451910: Niclosamide monohydrate

This classification denotes an antihelminthic agent C13H8Cl2N2O4.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 20Z25R1145, chemically known as benzamide, 5-chloro-n-(2-chloro-4-nitrophenyl)-2-hydroxy-, hydrate (1:1), but more generally known as niclosamide monohydrate, which bears US NIH Compound Identifier 12296604. European Medicines Agency schedules Niclosamide monohydrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12175MIG.

Most nations, for tariff and trade purposes, schedule niclosamide monohydrate under HS 29242995 and SITC 51479. As of Q4 2014, NICLOSAMIDE MONOHYDRATE remains US FDA's Preferred Term for this commodity. SMILES: C1CC(C(CC1[N+](=O)[O-])CL)NC(=O)C2CC(CCC2O)CL.O.

UNSPSC 51451910 Niclosamide monohydrate is a Commodity code that should describe pharmaceutical active ingredients for antimicrobial use; however, the most recent state and local contract opportunities posted under this code show little relevant activity. The Illinois Department of Public Health awarded a pharmaceutical warehouse piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC for Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—neither of which is niclosamide monohydrate. Seminole County, Florida posted an IFB for Naloxone and Safe Drug Deactivation Systems, also unrelated to the code's nominal scope. The mismatch between the code name and the actual procurement activity suggests either miscoding by the issuing bodies or limited recent market activity under the intended commodity classification.

State and local agencies appear to be using this code infrequently or inaccurately for pharmaceutical procurement. The Illinois contract, awarded on August 28, 2026, was a completed IFB through a cooperative purchasing vehicle (MMCAP Infuse) with a total award of $2,999,999.11 over the contract term including renewals; the Seminole County opportunity posted June 30, 2026, with a July 26, 2023 due date, was an IFB for public health supplies with quarterly delivery to Sanford, Florida. Neither record demonstrates active procurement of niclosamide monohydrate itself. Business development professionals should verify the accuracy of this code with issuing bodies before pursuing opportunities tagged to it, as the recent record does not support a clear market signal for the intended commodity.
