UNSPSC 31211607: Ultraviolet inhibitor

An additive that prevents fading or changing of color due to exposure to ultra violet light.

UNSPSC 31211607 Ultraviolet inhibitor is a Commodity code that in recent state and local procurement activity maps primarily to exterior painting and surface-protection materials for public-facility maintenance and repair rather than chemical additives in the narrow sense. The code appears under work solicitations for building facade restoration, graffiti abatement, and routine institutional painting where UV-resistant coatings and protective finishes are specified as part of the scope. State and local governments buying under this code include city community-development authorities, county public-works departments, school districts, and special-purpose districts managing facilities maintenance. The issuing bodies range from municipal housing authorities to county departments managing countywide infrastructure to school districts establishing vendor rosters for as-needed supplies.
