UNSPSC 51143102: Aloxiprin or aluminium acetylsalicylate

This classification denotes a pharmacologic substance and aluminium acetylsalicylate and unclear, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 6QT214X4XU. European Medicines Agency schedules Aloxiprin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB00370MIG. Aloxiprin generally arises in the molecular formula C9H8O4.2AL.3O.

The term ALOXIPRIN is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 19 1975, list 5.) ALOXIPRIN is scheduled in the U.S. International Trade Commission's Harmonized Tariff System (HTS) Pharmaceutical Appendix. SMILES: CC(=O)OC1=CC=CC=C1C(=O)[O-].CC(=O)OC1=CC=CC=C1C(=O)[O-].[OH-].[Al+3].

UNSPSC 51143102 Aloxiprin or aluminium acetylsalicylate is a Commodity code that in recent state and local procurement activity maps primarily to liquid aluminum sulfate (alum) used in municipal wastewater treatment operations, not pharmaceutical aloxiprin products as the code name suggests. State and local governments procure this chemical as a coagulant to remove soluble phosphorus and other contaminants during the activated sludge process at water treatment facilities. The issuing bodies soliciting under this code span municipal water and wastewater utilities, with the City of Austin's water authority representing the primary recent buyer. Work involves bulk liquid chemical supply with strict purity, concentration, and compliance requirements, along with delivery logistics and inventory management at regional distribution facilities.

The code shows limited recent activity. The City of Austin issued IFB 2200 CSH1061 on July 27, 2026 for 179,200 gallons annually of unpackaged liquid aluminum sulfate at 47–49% concentration, with bids due August 25, 2026 and questions due August 10, 2026. The solicitation applies local and small business preferences (5% discount for local businesses with headquarters in the Austin-Round Rock-San Marcos MSA on bids up to $500,000 and 3% on higher bids), requires NSF approval and AWWA B403 compliance, mandates three current municipal references from Texas facilities, and specifies a primary distribution facility within 500 miles of Austin with an alternate backup location. A second opportunity tagged to this code—the City of Tampa Fire Rescue's ITB 25-P-00157 for medical aid supplies posted in April 2026—represents a clear mismatch and does not reflect actual activity under the code. Geographic presence is concentrated in Texas, with Austin representing the dominant recent solicitation.
