UNSPSC 31121811: Brass ceramic mold machined castings

UNSPSC 31121811 Brass ceramic mold machined castings, a Commodity code, describes products that state and local governments procure for water utility infrastructure repair and maintenance, though recent solicitations under this code show a notable mismatch between the nominal product category and actual purchases. The City of Madison, Wisconsin, Water Utility has posted two RFQs in early 2026 for stainless steel pipe repair clamps and cast iron curb box assemblies — neither of which align with the "brass ceramic mold machined castings" descriptor. Water utilities represent the primary issuing body under this code in available records, with Madison appearing as a repeat buyer across multiple infrastructure component categories. The scope of work encompasses manufactured water system components including clamps, curb boxes, lids, extensions, and related hardware specified to exact material compositions, dimensions, and assembly standards, with acceptable manufacturers listed in the solicitation documents and local vendor preference scoring applied during evaluation.

Madison, Wisconsin, dominates recent activity under this code, with both posted opportunities due March 17, 2026. The City of Madison Finance Department's Purchasing Services, acting on behalf of the Madison Water Utility, issued RFQ 5518 for 175 stainless steel pipe repair clamps in eleven line item variations (posted March 3, 2026) and RFQ 5517 for 150 curb box assemblies with components including dust caps, extensions, lids, and rods specified to Bingham & Taylor model 94F construction (posted March 3, 2026). Both solicitations specify delivered FOB pricing to Madison, evaluate bids on cost, quality, warranty, delivery timeframe, and past performance, extend local vendor preference advantages to registered local suppliers, and require quotes firm for one year. No other geographic regions or issuing bodies appear in the available recent-opportunities block, limiting visibility into the breadth of activity under this code.
