UNSPSC 31141800: Reaction injection moldings RIM

UNSPSC 31141800 Reaction injection moldings (RIM) is a Class code covering specialized injection molding equipment and related manufacturing machinery that state and local governments, primarily educational and research institutions, procure for laboratory and production use. The University of Southern Mississippi's Procurement and Contract Services solicited sealed bids in May 2026 for a 110-ton electric injection molding machine meeting precise technical specifications—including a 40mm screw diameter, 171-gram shot size, maximum barrel temperatures of 800°F, and a footprint fitting within the Mississippi Polymer Institute Processing Lab—demonstrating the specific technical requirements state and local buyers impose on equipment falling under this code. State and local demand under the code appears concentrated among higher-education institutions operating materials science, polymer, and engineering research facilities rather than municipalities, school districts, or transit authorities; the University of Southern Mississippi's recent solicitation reflects this pattern.

The code shows limited recent activity in state and local procurement; the University of Southern Mississippi's sealed-bid solicitation (RFx #3160008023, due May 12, 2026) represents the most recent identified opportunity. The University required F.O.B. Destination Freight Allowed pricing, a delivery lead time not exceeding 16 weeks, full-day installation and familiarization, three days of training, a minimum one-year warranty, and lifetime technical support, with contract award to the lowest responsible bidder meeting all specifications. No contract value was disclosed. Geographic scope is confined to Mississippi based on available records; no other states or jurisdictions posted opportunities under this code in the recent window. The lack of broader geographic activity and the singular recent opportunity suggest this code sees infrequent solicitation in the state and local market.
