UNSPSC 12171509: Reactive dye

Reactive dyes utilize a chromophore containing a substituent that is capable of directly reacting with the fibre substrate. The covalent bonds that attach the reactive dye to natural fibers make it among the most permanent of dyes.

UNSPSC 12171509 Reactive dye is a Commodity code that addresses chemical colorants used in textile and fabric dyeing processes where the dye forms a covalent bond with the fiber. State and local governments procure reactive dyes primarily through facilities maintenance departments, public works operations, and specialized textile or laundry services that require consistent color fastness and durability in fabrics used for uniforms, protective wear, institutional textiles, and vehicle upholstery. The code spans dyes suitable for cellulose fibers (cotton, linen, rayon) and protein fibers (wool, silk) in both powder and liquid formulations, typically purchased in bulk quantities to support in-house or contracted dyeing operations at correctional facilities, fire and rescue services, public health agencies, and transit authorities.

The recent-opportunities block provides no sourced state and local contract notices under this code, so current procurement activity cannot be characterized by issuing body, geographic spread, or representative recent solicitations. The sparse recent visibility on this Commodity code may reflect procurement practices where reactive dyes are acquired as subordinate line items within broader laundry, textile maintenance, or chemical supply contracts rather than as standalone solicitations, or where quantities and usage patterns at individual public agencies do not trigger formal competitive bidding thresholds.
