NIGP 88584: Sodium Hydroxide

NIGP 88584 Sodium Hydroxide, an Item code, covers caustic soda and sodium hydroxide solutions purchased by state and local governments primarily for water treatment, pool maintenance, and municipal chemical operations. State and local buyers source sodium hydroxide under this code as a line-item chemical in requirements contracts, typically bundled with other treatment chemicals or pool supplies and specified to strict water-quality standards (ANSI/AWWA and NSF/ANSI 60 certification) when destined for drinking water systems. Issuing bodies include city water utilities, public works departments, and municipal recreation divisions soliciting through IFB and RFP vehicles, with contract terms commonly structured as one-year base periods with four optional one-year renewals. Award is typically made to the lowest responsive and responsible bidder on individual line items, with pricing quoted per pound or per unit and delivery required within days of order placement.

Recent activity concentrates in the Southwest and Pacific Northwest.
