UNSPSC 42203423: Embolization spheres

In this classification, this commodity indicates a product used as a sphere involved in the artificial formation or development of an embolus in a medical setting. US FDA regulates Embolization spheres under 21 CFR 870.33 and under FDA product code KRD. Most nations, for tariff and trade purposes, schedule these products under HS 901819.

UNSPSC 42203423 Embolization spheres (Commodity) appears in state and local procurement activity primarily through cooperative purchasing vehicles and institutional solicitations, though recent opportunities show substantial mislabeling against the code's actual scope. The three opportunities with material procurement substance—a Sourcewell law enforcement equipment RFP, a Klein ISD career technical education and advanced academics RFP, and a Clay County Board of County Commissioners IFB for physicals and drug testing services—contain no reference to embolization spheres or related medical devices. A Texas A&M University System ITB for a ceiling-mounted flexible C-arm (a medical imaging device sometimes used alongside embolization equipment in interventional radiology) similarly does not specify embolization spheres as a line item or deliverable. State and local jurisdictions that do procure medical devices and supplies typically do so through health systems, hospital districts, and university research facilities rather than general-purpose procurement offices, and cooperative purchasing agreements often bundle medical equipment and supplies across broad categories rather than individual device lines.

The recent posting activity shows no identifiable pattern of state and local governments actively soliciting embolization spheres as a standalone commodity. The code sees no material recent activity grounded in actual procurement of this specific device. Vendors pursuing opportunities coded to this UNSPSC should verify that opportunities are substantively related to embolization spheres procurement before investing in proposal development, as the recent public records show material misclassification of otherwise unrelated equipment and services solicitations.
