UNSPSC 51441577 Barium sulfate is a Commodity code that in practice covers radiologic and X-ray equipment, related inspection systems, and associated warranty and maintenance services procured by state and local health, corrections, and transportation jurisdictions. Recent opportunities show issuing bodies soliciting radiologic equipment installations for educational institutions, extended warranties for diagnostic and security X-ray systems, maintenance service plans for specialized X-ray inspection platforms, and chemical supplies used in industrial or water-treatment applications—a scope considerably broader than the code's nominal name suggests. The mix of issuing bodies includes county correction departments, county aviation authorities, county-level education systems, and county utilities or environmental agencies, with no single repeat buyer dominating recent activity.

Geographic activity concentrates in Florida and Arizona, with Maricopa County, Escambia County, Broward County, and Pasco County all posting opportunities between June and October 2026. Representative recent opportunities include Maricopa County's IFB 362910 (posted October 1, 2026, due October 22, 2026) for radiologic equipment and installation at three colleges; Escambia County Correction's sole-source IFB SSCORALM2526005 (posted August 12, 2026, due August 19, 2026) for an extended warranty on specified X-ray machines; and Broward County Aviation Department's RFI BLD2132311F1 (posted June 25, 2026, due July 28, 2026) challenging a proposed sole-source designation for Rapiscan X-ray inspection system maintenance services. The diversity of issuing bodies and the specific equipment types named suggest that vendors should verify code assignment against actual scope statements in notices, as state and local procurement offices sometimes tag equipment and services with codes that do not align closely with their nominal classification.
