NIGP 14515: Acid

NIGP 14515 Acid, an Item code, covers the procurement of chemical acids for operational and treatment purposes by state and local governments. The City of Phoenix Water Services Department is actively soliciting hydrochloric and citric acid in bulk quantities—31.45% hydrochloric acid in 330-gallon totes, 30% hydrochloric acid in 55-gallon drums and 1-gallon containers, and 50% citric acid in 330-gallon totes—reflecting the core application of this code in municipal water treatment and infrastructure maintenance. Solicitations under the code require bidders to meet strict hazardous materials handling, NSF compliance, and third-party laboratory certification standards, with comprehensive Safety Data Sheets and quality analysis documentation mandated as part of submission requirements. Water utilities and public works departments dominate recent activity under this code, with acid procurement typically structured as multi-year competitively bid contracts.

The City of Phoenix Water Services Department issued IFB 26-0104 on September 24, 2026, for a five-year hydrochloric and citric acid supply contract with a response deadline of October 16, 2025, and a non-mandatory pre-offer conference scheduled for October 7, 2025, via Webex. The procurement includes specific Disadvantaged Business Enterprise participation requirements and small business participation tracking through the City's Certification and Compliance System, mandating monthly DBE reporting and good faith outreach to certified suppliers. Unit pricing is required across container sizes ranging from 20 to 50 gallons, with contract commencement targeted for on or about November 15, 2025. The contract allows the City to adjust purchase volumes and modify pricing after the first year. Geographic activity under this code is currently concentrated in the Southwest, with limited recent visibility into broader national state and local demand.
