NIGP 00521: Abrasives, Sandblasting, Metal

NIGP 00521 Abrasives, Sandblasting, Metal is an Item code encompassing blast abrasive materials — primarily copper slag and related media — procured by state and local water authorities, county maintenance departments, and specialized public entities for infrastructure cleaning and surface preparation. The Brazos River Authority in Texas, a state-level water authority, issued RFB No. 26-1388 in May 2026 seeking copper slag abrasive for spillway gate surface preparation, specified to Black Diamond standards with precise bulk density, hardness, and silica-content tolerances. The solicitation illustrates the technical specificity of this commodity: respondents bid on sealed terms with lowest responsible bid driving award, and the authority explicitly encouraged small, minority, women-owned, and historically underutilized businesses to respond.

Activity under this code remains light based on recent postings. The Brazos River Authority RFB closing May 21, 2026, stands as the primary concrete recent opportunity; the code shows no additional active procurements with defined scope in the recent state and local opportunity feed. Texas appears to be the focal geography for this code segment, driven by the BRA's materials-handling needs at bulk water infrastructure. Given the specialized nature of blast abrasive procurement — confined to agencies managing steel or composite surfaces at scale — the issuing-body base remains narrow, concentrating on water authorities and regional infrastructure entities rather than general municipal or county purchasing offices.
