UNSPSC 47101578: Auxiliary plant and component

Any plant that forms part of a land-use system and provides a service and/or a product that is secondary to the main outputs of a system, can be classified as an auxiliary plant.

UNSPSC 47101578 Auxiliary plant and component (Commodity) covers discrete electrical and transit-system parts that state and local buyers source on a recurring basis—dual fixture light assemblies, electrical covers, power converters, traction power fuses, solenoid lock switches, Schneider Electric components, push buttons, and industrial electrical supplies. The issuing bodies are transit authorities (Dallas Area Rapid Transit Authority, Trinity Metro, Orange County Transportation Authority), county governments (Chatham County Sheriff's Office, Hillsborough County), cities (City of Tampa, City of Atlanta), school districts (Northside Independent School District), and state agencies (Texas Department of Criminal Justice). Dallas Area Rapid Transit Authority appears most frequently in recent solicitations, issuing multiple IFBs for specific electrical and mechanical components with response deadlines in September and October 2026.

Recent activity concentrates in Texas (Dallas, San Antonio, Tarrant County) and Florida (Hillsborough County, Tampa, Atlanta), with scattered solicitations across other states. Representative opportunities include Dallas Area Rapid Transit Authority IFB 2100939 for a dual fixture light assembly due October 20, 2026, and DART solicitation 2100940 for a power converter due October 16, 2026, both mandating FOB Destination shipping with freight included, Net 30 payment terms, and strict on-time delivery requirements with grounds for default termination for delays. Hillsborough County Board of County Commissioners issued ITB 26-00277 for Schneider brand electrical components with an estimated contract value of $519,787.19 over two years, bids due June 18, 2026, requiring delivery within 15 days to four warehouse locations across Tampa Bay. Trinity Metro established an IDIQ contract for electrical materials across Tarrant County facilities with responses due August 20, 2026. Orange County Transportation Authority's RFQ 250243 for industrial electrical supplies was budgeted at $10,000 for one year with renewal option and required delivery within four calendar days of order. Vendors pursuing this code should expect tight delivery windows, firm fixed pricing, and material payment and performance conditions in purchase order terms.
