UNSPSC 39121117: Buss bar

A solid electrical conductor through which an electric current passes and is normally used for very high current or power circuits.

UNSPSC 39121117 Bus bar (Commodity) covers aluminum seamless tubing and related electrical bus infrastructure components for utility substations, as evidenced by recent state and local solicitations requesting aluminum pipe in various diameters and clamp bus supports for electrical distribution systems. State and local governments procuring under this code include municipalities operating electric utilities, school districts, and public entities purchasing through cooperative procurement vehicles. The City of Austin Purchasing Office represents the most active recent buyer, soliciting aluminum seamless tubing meeting ASTM B 241 specifications and associated bus support hardware for Austin Energy. Scope ranges from high-volume piping orders with exacting material and dimensional tolerances to discrete hardware components such as clamp bus supports designed for specific conductor sizes; recent specifications emphasize conductor alloys, bending capability, electrical conductivity standards, and approved manufacturer lists.

Recent activity concentrates in Texas. The City of Austin issued two quotations in October 2026: IFQ 1100 AGM1027 for bus pipe (aluminum seamless tubing in 2.5-inch and 4-inch diameters, due October 19, 2026 at 2:00 p.m.) and IFQ 1100 CPG1089 for 100 clamp bus supports (5-inch bus head clamp for 4-inch aluminum tubing, due October 14, 2026 at 2:00 p.m.), both following a tiered SBE/M/WBE solicitation approach with fallback to open bidding if adequate small or minority-owned quotes are not received. Northside Independent School District in San Antonio posted IFB 2026098 for electrical equipment, parts, and supplies (due July 1, 2026), though the source does not confirm bus bar components were specifically solicited under that broader electrical equipment scope. A Sourcewell cooperative RFP for law enforcement equipment (RFP #061626, due June 16, 2026) is unrelated to bus bar procurement. Respondents to City of Austin solicitations must meet lead-time expectations, provide FOB Destination pricing inclusive of freight, certify non-debarment and wage-theft compliance, and maintain minimum commercial liability insurance of $500,000 per occurrence.
