UNSPSC 51386500: Combination amino acids/proteins

This classification denotes combination drugs that consist of a) organic compounds that generally contain an amino (-NH2) and a carboxyl (-COOH) group; and b) linear polypeptides that are synthesized on ribosomes and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. Typical combination amino acid/protein constituents are glycerin and isoleucine.

UNSPSC 51386500 Combination amino acids/proteins, a Class code, covers infant formula and protein-based medical nutritionals supplied through state health and human services procurement. State and local governments buy infant formula for WIC programs, enteral feeding supplies and formulas for developmental centers and medical facilities, and related protein-based medical nutrition products under this code. Soliciting bodies include state health departments, developmental centers operated by state agencies, and county social services authorities. The Michigan Department of Health and Human Services and Illinois Department of Human Services appear as repeat buyers in recent activity.

Recent solicitations span the Midwest and Southeast. Michigan MDHHS issued multiple RFPs for a WIC Infant Formula Rebate Program contract covering milk-based and soy-based formulas in powder, liquid concentrate, and ready-to-feed forms, with proposals due April 6, 2026 and April 8, 2026, and a five-year term from November 1, 2026 through October 31, 2031; the contract covers approximately 13.1 million units across 83 counties serving roughly 41,100 WIC infants. The award was made to Mead Johnson & Company, LLC at $38,223.023 monthly net price compared to Abbott Laboratories' $232,243.763. Illinois's Murray Developmental Center in Centralia issued two successive IFBs for durable medical equipment vendors including enteral feeding supplies and pumps, with bids due June 10, 2026 and June 30, 2026, pricing dictated by Medicare Part B fee schedules, and contract terms through June 30, 2027. Pasco County, Florida issued an RFQ for copper sulfate chemicals on June 3, 2026 with proposals due June 26, 2026, which is unrelated to the code's nominal scope. Gwinnett County Board of Commissioners in Georgia issued an IB for supplemental groceries including miscellaneous food items on March 26, 2026 with bids due May 6, 2026, also outside the code's primary focus.
