UNSPSC 51386502 Isoleucine/leucine/valine is a Commodity code that in recent state and local procurement appears primarily tied to infant formula rebate contracting under the WIC program rather than narrow amino-acid procurement. The Texas Health and Human Services Commission's October 2026 IFB for WIC infant formula rebates solicits contracts covering milk-based and soy-based formula in concentrated liquid, powdered, and ready-to-feed forms across Texas, Minnesota, Iowa, and the Choctaw Nation of Oklahoma—a five-jurisdiction scope serving approximately 207,707 monthly WIC participants. Issuing bodies under this code are predominantly state health and human services agencies administering nutrition assistance programs; the recent opportunities block shows no city, county, school district, or transit authority activity. Contractors must hold a minimum of two years of formula rebate experience, register with the U.S. Department of Health and Human Services under the Food, Drug and Cosmetic Act, and comply with all federal WIC regulations under 7 CFR 246 and state HUB subcontracting requirements.

The geographic concentration is heavy in the South and Southwest. The Texas Health and Human Services Commission WIC Infant Formula Rebate IFB (HHS0016707) with a response deadline of January 11, 2027 at 10:30 AM Central Time represents the most recent and most substantial opportunity; questions close October 30, 2026 by 1:00 PM Central Time, and the anticipated award date is February 3, 2027. The contract runs October 1, 2027 through September 30, 2032 with a potential one-year extension at HHS's sole discretion. Rebate pricing is structured on the manufacturer's lowest national wholesale cost per unit for full truckload quantities and adjusts automatically on a cent-for-cent basis for wholesale price changes of 10 cents or more after bid opening; rebate payments must be remitted within thirty calendar days, subject to one percent monthly penalty interest on outstanding balances. The source shows no additional comparable WIC formula rebate solicitations in other states during the recent period, suggesting that state and local procurement activity under this code remains concentrated in jurisdictions with active WIC programs and established rebate structures.
