UNSPSC 12350000: Compounds and mixtures

A compound contains atoms of different elements chemically combined together in a fixed ratio. A mixture is a combination of two or more substances where there is no chemical combination or reaction.

UNSPSC 12350000 Compounds and mixtures is a Family code covering the purchase of chemical formulations and bulk compounds that state and local governments use across utilities, facility operations, and specialized infrastructure. Recent state and local solicitations under this code show procurement demand concentrated in water treatment chemicals, cleaning agents, de-icing compounds, and specialty industrial liquids—with cities, counties, water departments, and school districts all active buyers.
