UNSPSC 51131628: Citric acid

This classification denotes a carboxylic acid with the molecular formula C6H8O7.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 2968PHW8QP. European Medicines Agency schedules citric acid in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12482MIG. The term citric acid monohydrate is a U.S. FDA designation. SMILES: OC(CC(=O)O)(CC(=O)O)C(=O)O.

UNSPSC 51131628 Citric acid is a Commodity code with no recent state and local procurement activity that matches its nominal scope. The single opportunity posted under this code—Sourcewell RFP #061626, issued May 12, 2026, with a response date of June 16, 2026—solicits law enforcement equipment through a cooperative purchasing vehicle serving multiple Washington counties (Franklin, Grant, Grays Harbor, Chelan, and Yakima) and thousands of governmental agencies, higher education institutions, school districts, and public entities across the United States and Canada. This procurement bears no relationship to citric acid and instead reflects a cataloging or data-tagging error. The code shows no meaningful recent activity in its actual commodity scope.

State and local buyers do not appear to be using this code for citric acid purchases in current solicitation activity. Citric acid procurement—when it occurs under state and local contract—may be absorbed into broader commodity or chemical-supply codes rather than classified to this Commodity-level designation, or it may be addressed through regional or state-level cooperative-purchasing agreements that do not post individual RFPs. Firms targeting state and local citric acid business should monitor broader chemical or food-additive commodity codes and track cooperative-purchasing catalogs rather than watch this code for buying signals.
