NIGP 18024: Bicarbonates and Carbonates

NIGP 18024 Bicarbonates and Carbonates, an Item code, covers the procurement of bicarbonate and carbonate compounds used across state and local government operations, including sodium bicarbonate, potassium carbonate, calcium carbonate, and related chemical formulations. State and local agencies use these materials for water treatment and pH adjustment, cleaning and deodorizing applications in facilities management, laboratory and analytical work, and specialized industrial or institutional processes. The mix of issuing bodies spans state environmental and public-health departments, county water authorities and sanitation districts, municipal water utilities, school districts maintaining laboratory and facilities infrastructure, and transit authorities managing fleet and facility operations.

The source provides no recent state and local contract opportunities under this code to establish geographic concentration or identify representative recent solicitations. Activity under NIGP 18024 appears to be either managed through standing cooperative purchasing agreements, smaller routine procurements that do not publish full RFP or IFB notices, or both—a pattern common for commodity chemicals where state and local buyers maintain existing vendor relationships or access pre-negotiated state or regional cooperative contracts rather than issuing frequent open solicitations.
