UNSPSC 32121611: Restrictor plate or air restrictor

A device installed at the intake of an engine to limit its power.

UNSPSC 32121611 Restrictor plate or air restrictor is a Commodity code that, based on recent state and local opportunities, does not align with actual purchasing activity under this designation. The recent solicitations posted under this code involve electrical components, equipment, and systems—including SEL protection relays, pump station control panels, electrical materials, motor control centers, ballasts and capacitors, and Schneider Electric components—none of which constitute restrictors or air restrictors in any conventional sense. The disconnect between the code's nominal scope and the work being tagged suggests either systematic miscoding by issuing bodies or that the code itself is not actively used for state and local procurements matching its intended product definition.

The issuing bodies represented in the recent postings include utility authorities (Kissimmee Utility Authority in Florida, Trinity Metro serving Tarrant County, Texas), county governments (Hillsborough County and Gwinnett County), school districts (Northside Independent School District in San Antonio, Texas), and special-purpose districts (Bay County and City of Bartow in Florida). Solicitations span Florida, Texas, and Georgia with notice types including RFQ, ITB, and IFB. Representative recent opportunities include Kissimmee Utility Authority's sole-source RFQ for SEL 451 and SEL 751 protection relays (SS26054SH, due August 24, 2026), Hillsborough County's ITB for pump station control panels and enclosures (ITB2600393, due September 29, 2026, estimated at $3.66 million over two years), and Gwinnett County's competitive quote for ballasts and capacitors for Parks and Recreation (PA028-26, due June 12, 2026). Given the consistent mismatch between code and content, this code shows little relevant recent activity for practitioners pursuing restrictor plate or air restrictor supply and installation work in state and local markets.
