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 is a Class code that covers specialized nutritional and medical formulas state and local governments procure to support vulnerable populations and institutional health care. The recent solicitations under this code show state health and human services agencies buying infant formula for WIC (Women, Infants, and Children) programs in multiple states, and developmental centers sourcing durable medical equipment including enteral feeding supplies and nutritional support products. The scope encompasses milk-based and soy-based infant formulas in concentrated liquid, powdered, and ready-to-feed forms, as well as enteral feeding pumps and associated supplies provided to institutional facilities. Issuing bodies include state health and human services commissions and departments managing WIC and developmental care; the Texas Health and Human Services Commission and Illinois Department of Human Services are recent repeat solicitors under this code.

The code sees active procurement in Texas, Minnesota, Iowa, Illinois, and the Choctaw Nation of Oklahoma. The Texas Health and Human Services Commission issued IFB HHS0016707 on October 14, 2026 for WIC infant formula rebate contracts serving Texas (178,075 monthly participants), Minnesota (15,130), Iowa (13,477), and the Choctaw Nation (approximately 1,025) with responses due January 11, 2027 at 10:30 AM Central Time. The procurement anticipates awarding up to two contracts—one for milk-based and one for soy-based formula—with a five-year performance term from October 1, 2027 through September 30, 2032 and a potential one-year extension. Bidders must demonstrate a minimum of two years of relevant formula rebate experience and comply with HUB subcontracting plan requirements and 7 CFR 246 federal WIC regulations. Murray Developmental Center in Centralia, Illinois solicited DME vendors under IFB 27444DHSDEVDIB52788 (due June 10, 2026) and IFB 27444DHSDEVDIB52936 (due June 30, 2026) for supplies including enteral feeding products, with pricing dictated by Medicare Part B fee schedules and contract terms through June 30, 2027.
