UNSPSC 31391602: Ceramic medium precision machining

Ceramic objects that have been machined to tolerances equal to or greater than 0.020 mm for major dimensions

UNSPSC 31391602 Ceramic medium precision machining (Commodity) does not align with the recent state and local procurement activity tagged under this code. The sole recent opportunity on record shows the City of Midland, Texas, acting on behalf of Mason County, soliciting competitive bids for 71 fire hydrants — 45 units of 4-foot hydrants, 20 units of 5-foot hydrants, and 6 units of 6-foot hydrants — under the U25-01 Fire Hydrant Replacement Project. Fire hydrant procurement is infrastructure equipment supply, not ceramic medium precision machining. The mismatch suggests either a tagging error in the source database or that this Commodity code does not reflect the actual work state and local governments are purchasing under it.

The City of Midland IFB posted March 26, 2026, with bids due April 9, 2026, through the Bonfire e-procurement system. Bidders must submit itemized pricing with unit prices, descriptive literature, delivery timeframes, brand names, and product numbers, with all hydrants delivered F.O.B. Midland and freight prepaid. The City reserves award discretion by item or total bid to the lowest responsible bidder or best value, with local preference applying under Texas Local Government Code Section 271.9051 if a local bidder's price falls within five percent of the lowest non-local bid. No set-asides for disadvantaged enterprises are specified. Bidders must execute a Non-Collusion Statement, provide workers' compensation insurance with the City named as additional insured within 21 days of award, and complete a Conflict of Interest Questionnaire and Affidavit of Eligibility if applicable. No incumbent vendor, award value, or budget range is identified in the procurement documents. Because the single tracked opportunity shows no affinity to ceramic machining work, this code shows little relevant recent activity for firms in that sector.
