NIGP 50515: Bluing, Inks, and Vat Dyes

NIGP 50515 Bluing, Inks, and Vat Dyes, an Item code, covers industrial colorants and chemical treatments used in textile manufacturing, printing, and metalworking operations that state and local governments procure for maintenance facilities, fleet services, and institutional laundries. The code captures bluing agents for fabric brightening, printing inks in various formulations, and vat dyes for batch dyeing processes — products typically bought as consumables or in bulk by purchasing departments supporting operational needs rather than as end goods for direct service delivery.

No recent state and local contract opportunities under NIGP 50515 appear in the available sourcing data. This sparse or nonexistent recent activity suggests that purchases under this code occur either through standing cooperative agreements, small-dollar routine buys routed through existing vendor relationships, or as line items bundled with broader textile or chemical commodity solicitations rather than as standalone procurements.
