NIGP 40028: Castings, Copper

NIGP 40028 Castings, Copper (Item) addresses copper compounds and derivatives procured by state and local governments, though recent activity under this code reflects demand for copper sulfate in crystal and liquid forms rather than castings per se. Pasco County, Florida solicited vendors in June 2026 to supply large copper sulfate crystals and liquid copper sulfate on an as-needed basis through an indefinite-quantity arrangement, suggesting the code captures water-treatment chemicals and related copper-based compounds alongside traditional casting products. The issuing bodies pursuing copper-related supplies under this Item code span county governments and their operational needs, though a single recent opportunity limits visibility into the broader issuing-body mix across state departments, municipalities, school districts, and special-purpose districts.

Recent procurement activity under NIGP 40028 is concentrated in Florida, as evidenced by Pasco County's June 2026 RFQ (RFQFP261004) with a proposal due date of June 26, 2026. The scope of Pasco County's solicitation—copper sulfate for water or facilities treatment—indicates that practical demand under this Item code diverges from the legacy NIGP category name, with state and local governments buying chemical compounds and process materials rather than finished copper castings. The single posted opportunity provides limited geographic spread to characterize activity across other states or regions.
