UNSPSC 51201806: Gamma IGG or immunoglobulin

This classification denotes gamma-chain antibodies.

UNSPSC 51201806 Gamma IGG or immunoglobulin is a Commodity code covering biological immunological products procured by state health departments. The single recent state and local opportunity under this code shows minimal substantive activity: the Mississippi State Department of Health posted a sole source procurement notice for Yellow Fever Vaccine from Sanofi Pasteur on July 13, 2026, with an objection deadline of August 3, 2026. The notice does not specify quantity, contract term, estimated value, or pricing. This is a notice of proposed sole source purchase rather than a standard competitive solicitation, and objections to sole source classification must include written documentation demonstrating that alternative vendors can supply the vaccine. If the department receives substantiated objections, it will withdraw the sole source notice and conduct an advertised competitive bid or selection process; if it determines only one source exists, it will appeal to the Public Procurement Review Board.

The code shows little recent activity in state and local procurement. The single opportunity identified is a vaccine procurement by a state health department, a narrow use case that does not reflect broad solicitation activity across multiple jurisdictions or commodity types. Without additional recent opportunities in the source record, the geographic and issuing-body spread cannot be characterized. Business development professionals should monitor whether additional health department procurements emerge under this code or whether sole source vaccine purchases dominate activity.
