UNSPSC 31391501: Plastic standard precision machining

Plastic objects that have been machined to tolerances equal to or greater than 0.050 mm for major dimensions

UNSPSC 31391501 Plastic standard precision machining is a Commodity code that, based on recent state and local solicitation activity, encompasses the procurement of specialized fire hydrants and related water utility infrastructure components manufactured to precise technical specifications. The code captures competitive bids for engineered hydrant systems delivered to municipal water departments and local government agencies responsible for fire suppression and water main protection. Municipalities and county governments acting through local purchasing offices are the primary issuing bodies under this code, procuring standardized equipment that must meet detailed technical specifications and conform to state or local construction standards.

The City of Midland, Texas, acting on behalf of Mason County, posted an IFB (Invitation for Bid) on March 26, 2026, for 71 fire hydrants in three configurations — 45 units of 4-foot hydrants, 20 units of 5-foot hydrants, and 6 units of 6-foot hydrants — with a response deadline of April 9, 2026. The procurement required itemized pricing, delivery timeframes in calendar days, brand identification, and F.O.B. delivery to Midland with freight prepaid. Local preference provisions under Texas Local Government Code Section 271.9051 applied, allowing the City to award to a local bidder within five percent of the lowest non-local bid based on economic development factors. Recent activity is concentrated in Texas; the source provides no indication of parallel procurement activity in other states or jurisdictions during the current period.
