UNSPSC 23281600: Heat treating machines

Heat treatment includes the controlled heating and cooling of materials at various rates. These treatments induce phase transformations that greatly influence mechanical properties, such as strength, hardness, ductility, toughness, and wear resistance.

UNSPSC 23281600 Heat treating machines is a Class code covering metalworking and industrial equipment that state and local governments procure for educational and operational use. Recent solicitations under this code show Texas A&M University System (TAMUS) repeatedly sourcing press brakes and CNC equipment—including a CNC lathe and machining center, CNC equipment, and machine shop, welding, and fabrication equipment—through ITBs posted between June and October 2026. The Texas Department of Transportation has also solicited OEM replacement parts for a Cincinnati Shear machine, a industrial metalworking tool, at its Production Shop in Austin. TAMUS is the dominant repeat buyer in the recent activity, posting four equipment-related ITBs within four months via the AggieBid electronic procurement platform. The scope of work centers on precision metalworking machinery and components—press brakes, CNC systems, shears, and associated mechanical parts such as bearings, gaskets, seals, clutches, springs, and fasteners—used in university machine shops, fabrication facilities, and state transportation maintenance operations.

Recent solicitation activity is concentrated in Texas, with TAMUS posting the bulk of opportunities (press brakes due October 29 and September 25, 2026; CNC lathe and machining center due July 23; CNC equipment due July 13; machine shop and fabrication equipment due July 15), and TxDOT issuing IFBs for Cincinnati Shear parts (due June 2 and April 16, 2026). California posted one RFB for a water table CNC Hypertherm plasma cutter due June 15, 2026, and Hillsborough County (Florida) posted a sole-source notice for composting equipment maintenance valued at $1,992,824.18 over five years, though this opportunity is tangential to the code's core metalworking machinery scope. TAMUS uses fixed-price ITB format with responses submitted electronically through AggieBid; TxDOT uses best-value IFB criteria under Texas Government Code 2155.074, with evaluation based on quality, reliability, delivery, past performance, and maintenance support capability. Vendors must register on the Centralized Master Bidders List and possess relevant NIGP classifications. Texas bid preferences include Texas-produced supplies, USA-produced goods, service-disabled veteran-owned businesses, and environmentally sensitive materials.
