UNSPSC 12171603: Carbon black

UNSPSC 12171603 Carbon black is a Commodity code under which state and local governments procure carbon black — a finely divided form of elemental carbon produced as a byproduct of incomplete combustion of heavy petroleum products — for use in rubber manufacturing, plastics, printing inks, coatings, and other industrial applications. Carbon black serves as a pigment, reinforcing agent, and performance additive across these end-use sectors. The code captures purchase of carbon black in bulk quantities, typically sourced from chemical suppliers and specialty material distributors serving state and local manufacturing facilities, transportation departments, and public works operations that rely on carbon-black-containing products such as tires, hoses, and sealants.

The <most-recent-state-local-contract-opportunities> block provided no recent solicitations under this code. Without posted RFP, RFQ, IFB, or ITB activity to reference, no geographic concentration, issuing-body mix, or representative opportunities can be identified from the source. A sparse or absent record under this commodity code may indicate that state and local procurement offices source carbon black through cooperative purchasing agreements, statewide blanket contracts, or indirect procurement embedded in larger materials-science or industrial-supply agreements rather than as standalone solicitations.
