UNSPSC 51131801: Fibrinogen

This classification denotes a plasma glycoprotein clotted by thrombin composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds, and which is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier N94833051K.

European Medicines Agency schedules Fibrinogen in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12502MIG. The term FIBRINOGEN is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 33, No. 10 1979, List 19.) Fibrinogen bears US NLM identifiers UMLS ID C0016006 and NCI Concept Code C25736.

UNSPSC 51131801 Fibrinogen, a Commodity code, shows minimal recent state and local procurement activity aligned with its nominal medical-supply scope. The single recent opportunity posted under this code—Sourcewell RFP #061626, issued May 12, 2026 with a June 16, 2026 response deadline—is tagged as Law Enforcement Equipment procurement and does not represent fibrinogen or related blood-product sourcing. The mismatch between the code's clinical hemostatic product designation and the actual solicitation scope suggests either a tagging error in the source or a misalignment between the UNSPSC hierarchy and how this particular cooperative purchasing vehicle categorizes its offerings.

Sourcewell, a Minnesota local government unit and service cooperative, is the issuing body, operating under Washington state cooperative purchasing law (RCW 39.34) and drawing participation from Franklin County, Grant County, Grays Harbor County, Chelan County, Yakima County, and numerous other U.S. and Canadian jurisdictions. The cooperative structure targets thousands of governmental agencies, higher education institutions, K-12 school districts, nonprofit organizations, tribal governments, and other public entities. Submissions must be made through the Sourcewell Procurement Portal by June 16, 2026 at 3:30 p.m. Central Time; no set-aside designations, disadvantaged-enterprise restrictions, or award values are identified in available documentation. Without additional recent opportunities confirming fibrinogen procurement patterns across state and local buyers, the code presents no clear market signal for pursuit at this time.
