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

NIGP 18004 Acids, Inorganic: Hydrochloric, Phosphoric, Sulfuric, Etc. is an Item code under which state and local governments procure inorganic acids for water treatment, wastewater management, facility maintenance, and chemical manufacturing. Recent solicitations show demand for hydrochloric acid (technical grade, 31.5–33.1% by weight for landfill leachate evaporators and 20 degrees Baumé for janitorial product manufacturing), phosphoric acid (85% technical for both wastewater pump stations and laundry manufacturing), and sulfuric acid (38% strength for pool and fountain pH adjustment). State and local buyers under this code span county environmental and public-works departments, city parks and recreation agencies, city wastewater departments, and statewide procurement offices acting on behalf of state criminal justice departments. Specification requirements are detailed and strict—including assay percentages, pH ranges, color limits, contaminant thresholds (chloride, iron, arsenic, lead, mercury at parts-per-million levels), specific gravity targets, and NSF certifications where applicable. Minimum order quantities range from several hundred pounds to 45,000 gallons depending on the product line and end use. Delivery timelines typically target three to ten working days from order receipt, with ongoing service contracts requiring weekly or bi-weekly scheduled drops plus emergency availability.

Recent activity concentrates in Texas and Florida. The Texas Comptroller of Public Accounts' Statewide Procurement Division posted IFB 304T26180A11 on June 30, 2026, due July 7, 2026, for five chemical line items including 12,480 pounds of hydrochloric acid and 24,000 pounds of phosphoric acid for the Texas Department of Criminal Justice's janitorial and laundry manufacturing, with contract terms through October 31, 2027, and three automatic renewal options. The City of Tampa Parks & Recreation Department issued ITB 25-P-00118 on June 24, 2026, for sodium hypochlorite and sulfuric acid delivery to pool and fountain sites, with an estimated contract value of $250,000 and one-year initial term plus two optional renewals. The City of Tampa's Wastewater Department solicited phosphoric acid and liquid enzymes under ITB 26P00135 (posted and due April 1, 2026) for three pump stations, with an estimated value of $50,000 and annual CPI escalation provisions. Hillsborough County's ITB 26-00158 (posted February 13, 2026, due March 4, 2026) sought technical-grade hydrochloric acid for its landfill leachate evaporator at an estimated three-year value of $412,957.50. Bidders typically must provide Certificates of Analysis, proof of manufacturer or authorized-distributor status, commercial general liability insurance ($500,000 to $5 million depending on scope), and NSF certifications or equivalent approvals; Texas preference designations, Texas SmartBuy administrative fees, and EBO/SLBE participation requirements apply in Texas and Florida jurisdictions respectively.
