UNSPSC 12164800: Water reducing agents

Additives used to control coagulation by dispersing the particles.

UNSPSC 12164800 Water reducing agents is a Class code that covers chemical additives and compounds used to reduce water content, improve flow properties, and enhance durability in construction materials and water treatment applications. Based on recent state and local solicitations, the code encompasses both construction-focused waterproofing agents and water treatment chemicals supplied to municipal utilities and higher-education facilities. Issuing bodies include public universities, municipal water districts, city governments, and county facilities management offices. The work typically involves supplying specialized chemicals for masonry restoration, waterproofing membranes, and potable or reclaimed water treatment systems on a blanket-order or supply-contract basis, with vendors expected to provide technical documentation, quality assurance procedures, relevant licensure, and hazardous-materials handling credentials.
