UNSPSC 31391504: Stainless steel standard precision machining

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

UNSPSC 31391504 Stainless steel standard precision machining is a Commodity code that in state and local procurement practice covers fire hydrants and similar metal-fabricated water infrastructure components meeting engineered technical specifications. The City of Midland, Texas recently solicited bids for 71 fire hydrants (45 units of 4-foot, 20 units of 5-foot, and 6 units of 6-foot models) as part of the U25-01 Fire Hydrant Replacement Project. Fire hydrant procurement appears to represent the primary transactional activity under this code in the state and local market. Municipal water and public works departments are the primary issuing bodies, with work focused on replacement and infrastructure renewal rather than new construction. Bidders must provide itemized unit pricing, descriptive literature, proposed delivery timeframes, and brand and product identification; all hydrants must meet attached technical specifications, be delivered F.O.B. Midland with freight prepaid, and comply with workers' compensation insurance requirements.

The City of Midland's fire hydrant solicitation closed on April 9, 2026, via the Bonfire e-procurement system as an IFB (Invitation for Bid). Texas local preference provisions apply under Texas Local Government Code Section 271.9051, allowing the City Council to award to a local bidder if the bid falls within five percent of the lowest non-local bid. The procurement documents do not identify an incumbent vendor or award budget. Recent activity under this code is limited; the source reports only one posted state or local opportunity in the recent window. Geographic concentration is not evident from the available data, with only the Texas municipal activity represented in the opportunities block.
