UNSPSC 51131814 Aprotinin, a Commodity code, nominally refers to a hemostatic pharmaceutical agent used in surgical and trauma settings. However, the recent state and local procurement activity tagged to this code shows a substantial mismatch: the lone recent opportunity is a Sourcewell RFP for law enforcement equipment, not pharmaceutical procurement. This divergence suggests the code may have been applied incorrectly in the source data or that aprotinin procurement through state and local channels is either inactive or untagged in current market signals. State and local buyers who do source aprotinin typically do so through health systems, hospital networks, and trauma centers as part of surgical supply chains, but no such opportunities appear in the recent record for this code.

Sourcewell, a State of Minnesota local government unit and service cooperative, issued RFP #061626 on May 12, 2026 with a response deadline of June 16, 2026, seeking to establish a cooperative purchasing vehicle for law enforcement equipment available to participating entities across Washington state (Franklin, Grant, Grays Harbor, Chelan, and Yakima counties named explicitly) and numerous other jurisdictions throughout the United States and Canada. The solicitation was posted exclusively through the Sourcewell Procurement Portal and sought to leverage collective buying power across governmental agencies, higher education institutions, K-12 school districts, nonprofit organizations, and tribal governments. The mismatch between the aprotinin commodity code and law enforcement equipment procurement indicates that the code assignment does not reflect actual buying activity in this market, limiting utility for vendors evaluating pharmaceutical or hemostatic-product opportunities under this code at the state and local level.
