UNSPSC 51131803: Thrombin

This classification denotes an enzyme formed from prothrombin that converts fibrinogen to fibrin, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 25ADE2236L. European Medicines Agency schedules Thrombin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15544MIG. The term THROMBIN is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 3, No. 3, 1989, List 29 and see Volume 22, No. 1, 2008, List 59).

As of Q4 2014, THROMBIN remains the US FDA Preferred Term for this commodity.

UNSPSC 51131803 Thrombin is a Commodity code that nominally covers coagulation-promoting pharmaceuticals used in clinical hemostasis and surgical settings. State and local procurement activity under this code shows a significant mismatch between the code's intended scope and actual buying behavior — the single recent opportunity tagged to this code is a law enforcement equipment solicitation, not a pharmaceutical or medical supply procurement. State and local health agencies, hospital systems, and medical procurement offices are the expected buyers for thrombin products, but the recent-opportunities block reveals no medical procurement activity under this code. The solicitation structure (cooperative purchasing through Sourcewell, a Minnesota local government unit) is typical for state and local consolidated procurements, yet the content — law enforcement equipment — bears no relationship to thrombin's clinical use.

Sourcewell issued RFP #061626 on May 12, 2026, with a response deadline of June 16, 2026 at 3:30 p.m. Central Time, on behalf of participating jurisdictions including Franklin, Grant, Grays Harbor, Chelan, and Yakima Counties in Washington state, along with numerous other governmental entities nationwide and in Canada. The lack of any relevant recent medical procurement activity under this code, combined with the clear tagging error in the single available opportunity, suggests that thrombin products do not currently flow through state and local procurement channels tracked under 51131803. Buyers seeking coagulation products should verify code assignment with issuing agencies directly rather than relying on this code's recent activity signal.
