UNSPSC 51201815 Histamine is a Commodity code that in recent state and local practice covers pharmaceutical products and biologics, though the single recent opportunity on file reflects a procurement mismatch: the Mississippi State Department of Health posted a sole source notice for Yellow Fever Vaccine from Sanofi Pasteur, Inc., which does not align with histamine as a pharmaceutical input or active ingredient. The code's nominal scope—histamine as a chemical or pharmaceutical component—does not map to the vaccine procurement actually posted under this code number. This suggests either a data-entry error in the original tagging or a state procurement system that applies commodity codes inconsistently across pharmaceutical categories.

The Mississippi State Department of Health's sole source notice, posted July 13, 2026, with objections due August 3, 2026 at 10:00 a.m. CST, is the only recent state or local opportunity in the source block. The notice invites any vendor believing an alternative source exists to submit written objection to Cynthia Brasher at the purchasing department; if substantiated objections are received, the department will conduct a competitive bid or selection process, and if none are received and the sole source is upheld, the matter will proceed to the Public Procurement Review Board. The notice does not specify contract value, term, or order quantity. The geographic activity is limited to Mississippi. Given the single opportunity and its mismatch to the code's histamine scope, this code shows minimal recent relevant activity for firms in the pharmaceutical or biological products space.
