NIGP 18004: Acids, Inorganic: Hydrochloric, Phosphoric, Sulfuric, etc.

NIGP 18004 Acids, Inorganic: Hydrochloric, Phosphoric, Sulfuric, Etc., Item, covers inorganic acid procurement by state and local water utilities, parks departments, and state procurement offices on behalf of corrections and manufacturing operations. State and local governments buy specific gravity–controlled hydrochloric, phosphoric, and sulfuric acid in bulk container sizes (330-gallon totes, 55-gallon drums, and smaller formats) for water treatment, pH adjustment, pool and fountain maintenance, and industrial chemical manufacturing. The City of Phoenix Water Services Department, City of Tampa Parks & Recreation Department, and the Texas Comptroller of Public Accounts (procuring for the Texas Department of Criminal Justice) represent the issuing bodies active under this code. These jurisdictions require NSF compliance certification, third-party laboratory quality analysis, Safety Data Sheets, and hazardous-materials handling protocols aligned with OSHA guidelines and environmental compliance standards. Some solicitations impose set-aside requirements—the Phoenix procurement includes Disadvantaged Business Enterprise and small business participation mandates; the Tampa procurement applies an Equal Business Opportunity program requiring U-WMBE and Small Local Business Enterprise participation with mandatory subcontractor intent documentation.

Recent procurement activity appears concentrated in Texas and Arizona. The City of Phoenix issued IFB 26-0104 for hydrochloric and citric acid with a response date of October 16, 2025, and a non-mandatory pre-offer conference scheduled for October 7, 2025, via Webex. The Texas Comptroller of Public Accounts released IFB 304T-26-180A1.1 on June 30, 2026, with bids due July 7, 2026, covering hydrochloric acid (20 Degrees Baume, 12,480 pounds) and phosphoric acid (85% technical, 24,000 pounds) among five line items totaling approximately 109,480 pounds for delivery to Austin, Texas.
