UNSPSC 12164606: Light and ultraviolet UV stabilizer

An additive used frequently in plastics, including cosmetics and films. The primary function is to protect the substance from the long-term degradation effects from light, most frequently ultraviolet light. Different UV stabilizers are utilized depending upon the substrate, intended functional life, and sensitivity to UV degradation.

UNSPSC 12164606 Light and ultraviolet UV stabilizer is a Commodity code, but recent state and local solicitations do not actually procure UV stabilizers under this code. Instead, the tagged opportunities acquire pool chemicals and water treatment chemicals more broadly—calcium hypochlorite, cyanuric acid, sodium hypochlorite, chlorine tablets, muriatic acid, and related maintenance products for municipal and school district facilities. The actual buying under this code reflects general-purpose pool and water treatment procurement, not UV-stabilizer chemistry specifically. School districts and municipal water and parks departments drive the recent activity. Three recent opportunities illustrate the pattern: the School Board of Pinellas County, Florida issued RFQ 25AM018 for swimming pool chemicals to deliver to five school locations by February 11, 2026, with an estimated annual contract value of approximately $35,000; the City of Tucson issued RFP 240203 for swimming pool supplies, chemicals, equipment, and related services with a non-mandatory pre-proposal meeting on June 3, 2024, and proposal submissions due June 13, 2024; and the City of Griffin, Georgia issued ITB #26-008 for water treatment chemicals with a May 28, 2026 bid deadline, seeking 16 different chemicals for six water treatment facilities across Fiscal Year 2027.

Geographic activity clusters in Florida, Arizona, and Georgia based on the recent postings. All three issuing bodies—school districts and municipal water and parks systems—require chemicals delivered FOB destination with freight included, in line-item or percentage-discount pricing models, and typically structure contracts for one-year initial terms with renewal options spanning two to four additional years. Bidders must meet standard compliance requirements including background screening, drug-free workplace certification, and debarment affidavits. The City of Tucson emphasizes local-storefront capability and installation or repair services beyond chemical supply alone, while both the Pinellas County schools and Griffin water system accept purchasing-card payments and permit price escalation tied to the Consumer Price Index at renewal. No explicit disadvantaged-enterprise set-asides are documented in the recent opportunities, though the Tucson solicitation references DBE participation language. This code shows limited recent activity concentrated in routine municipal and school-district pool and water operations—a steady, small-dollar segment without apparent growth signals or consolidation pressure.
