UNSPSC 13111076: Cross linked polyethylene PEX

A form of polyethylene with cross-links. It is formed into tubing, and is used predominantly in hydronic radiant heating systems, domestic water piping and insulation for high tension electrical cables.

UNSPSC 13111076 Cross linked polyethylene PEX is a Commodity code that state and local governments buy primarily as potable water distribution tubing for municipal water systems and building supply applications. Recent procurement activity shows school districts, water authorities, and municipal departments procuring PEX tubing for new construction, system upgrades, and replacement work in water delivery infrastructure. The material itself—flexible cross-linked polyethylene—serves as a cost-effective alternative to copper and rigid plastic piping in both new builds and retrofit projects. Issuing bodies span water utilities, municipal public works departments, school districts purchasing for facility upgrades, and county water systems. PEX appears frequently in lower-value, routine procurement activities where the material is bundled with other plumbing supplies or specified as part of larger water system contracts, rather than as a standalone commodity drawing significant independent notice activity.

The source provided contains no timestamped recent state and local contract opportunities under this code, so current geographic concentration and representative recent solicitations cannot be characterized from available data. Procurement professionals evaluating activity under this code should monitor water utility RFQs and municipal public works notices for routine purchasing cycles, which tend to cluster around spring and fall infrastructure seasons and often roll PEX specifications into broader plumbing or water-main contracts rather than standalone solicitations.
