UNSPSC 51171511: Algeldrate or aluminium hydroxide

This classification denotes a vaccine adjuvant with the molecular formula Al.3HO, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 5QB0T2IUN0, chemically known as aluminum hydroxide, dried (jp15/usp) but generally known as aluminium hydroxide, which bears US NIH Compound Identifier 6328211. European Medicines Agency schedules Aluminium hydroxide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB11700MIG.

World Health Organization schedules aluminium hydroxide in its Anatomical Therapeutic Chemical (ATC) Classification. Most nations schedule aluminium hydroxide under HS 28183000 and SITC 52266. SMILES: O.O.O.[AL].

UNSPSC 51171511 Algeldrate or aluminium hydroxide is a Commodity code with minimal recent state and local procurement activity. The single recent opportunity posted under this code—Collin County Community Supervision and Corrections Department RFP 2026-327 for offender specimen collection and drug testing services, due July 23, 2026—reflects a substantial mismatch between the code's nominal scope (pharmaceutical-grade aluminum hydroxide as an antacid or ingredient) and the work actually being solicited. The county's request centers on drug-testing laboratory operations, including staffing collection sites, immunoassay screening with LC/MS/MS or GC/MS confirmation, oral fluid and hair testing methodologies, and electronic result reporting—none of which involves procurement of algeldrate or aluminium hydroxide as a product. This code shows little relevant activity for vendors supplying antacid pharmaceuticals or chemical reagents to state and local buyers.

The mismatch between code and actual solicitation scope limits the utility of this Commodity code for business development targeting state and local drug-testing or laboratory services procurement. Collin County's estimated contract value of $600,000 over two years (with three optional one-year renewals) and emphasis on SAMHSA, Texas DPS, or CAP lab certification suggest that the county is seeking a qualified clinical laboratory services provider rather than a chemical supplier. Vendors pursuing state and local pharmaceutical or chemical supply opportunities should monitor higher-level family or class codes that capture laboratory supplies, pharmaceuticals, or clinical testing services more directly.
