UNSPSC 31391703: Steel high precision machining

Steel objects that have been machined to tolerances less than 0.020 mm for major dimensions

UNSPSC 31391703 Steel high precision machining is a Commodity code, but the recent state and local opportunity record shows a mismatch between the code's nominal scope and the actual work being solicited. The City of Midland, Texas, acting on behalf of Mason County, posted an IFB for 71 fire hydrants (45 units of 4-foot, 20 units of 5-foot, and 6 units of 6-foot) under the U25-01 Fire Hydrant Replacement Project—a straightforward equipment procurement task that does not align with precision machining of steel components. Fire hydrant supply and delivery, while potentially involving machined parts within the assembly, does not constitute the primary scope of work under this code. The procurement required itemized unit pricing, product literature, delivery timeframes, and F.O.B. delivery to the City of Midland with freight prepaid and included in bid price.

The source contains only one relevant recent opportunity under this code, posted March 26, 2026, with a response deadline of April 9, 2026. The City of Midland's purchasing process, conducted through the Bonfire e-procurement system, applied Texas Local Government Code provisions including local preference (within five percent price tolerance) and best-value evaluation criteria. No MBE, DBE, SBE, or other set-asides were specified. The record does not identify prior similar solicitations under this code in other jurisdictions or regions, nor does it support characterization of issuing-body mix or geographic concentration. This code shows minimal documented recent activity in state and local procurement relative to its abstract scope—the single posted opportunity reflects commodity-level equipment purchase rather than precision machining services.
