UNSPSC 31121511: Brass shell mold machined castings

UNSPSC 31121511 Brass shell mold machined castings, a Commodity code, spans cast brass and aluminum components that state and local governments procure for infrastructure signage, water system repairs, and commemorative installations. The work involves fabrication of cast plaques, letters, seals, and service parts to specification, often with custom finishes and material selections. Issuing bodies include state departments of public safety, municipal water utilities, and city procurement offices soliciting both one-off commemorative projects and standing annual requirements contracts for replacement parts inventory. The scope reflects a mix of artistic or ceremonial installations alongside utilitarian water system components, with vendors typically providing design consultation, material sourcing, precision casting, and finishing work under fixed or lump-sum pricing structures.

Recent activity concentrates in Texas. The Texas Department of Public Safety posted an Invitation for Bid (IFB) on September 25, 2026 for the Legacy Hall Courtyard Display (solicitation 40526R0025759, due October 12, 2026), calling for three cast plaques—a 65-inch diameter cast bronze seal with 3D prismatic detail and dark oxide finish, cast aluminum lettering pieces with black anodized finish, and cast aluminum stars—with all components specified as "or equal" and recycled-material preferences noted. The City of Arlington, Texas concurrently posted an annual requirements contract (solicitation 270041, due October 22, 2026) for brass water repair parts including service line fittings, accessories, and tapping saddles for warehouse stock replenishment. Bidders in both procurements must comply with state employment verification, drug-free workplace, and records retention requirements; DPS procurements add CJIS security compliance and background-check mandates for facility access. Both jurisdictions discourage late submissions and require electronic or sealed-envelope compliance.
