UNSPSC 12352204 Enzymes is a Commodity code that in state and local practice covers chemical inputs for water treatment and infrastructure maintenance. The City of Phoenix Water Services Department's recent Invitation for Bid (IFB 260104) illustrates the concrete scope: procurement of hydrochloric and citric acid in multiple concentrations and container sizes (330-gallon totes, 55-gallon drums, and 1-gallon containers) for a five-year contract. Water utilities represent the primary issuing bodies under this code, though the broader Commodity tier may capture related chemical inputs for treatment processes across municipal water systems. The Phoenix solicitation mandates comprehensive documentation including Safety Data Sheets, NSF compliance proof, certified third-party laboratory quality analysis, and adherence to OSHA hazardous-materials handling and labeling standards. Disadvantaged Business Enterprise (DBE) and Small Business Participation Plan requirements apply, with monthly tracking and annual reporting through the City's Certification and Compliance System.

Arizona is the primary recent jurisdiction showing activity under this code, with the City of Phoenix posting the IFB on September 24, 2026, for a five-year contract commencing on or about November 15, 2025. The solicitation included a non-mandatory pre-offer conference on October 7, 2025, via Webex, with questions due by October 9, 2025, and sealed proposals due October 16, 2025, at 2:00 pm. The City reserves the right to adjust purchase volumes and modify pricing after the first contract year. No other recent state or local opportunities appear in the source block, indicating limited current activity visibility under this specific Commodity code.
