UNSPSC 32121804: Crystal filter

A filter that uses the crystal resonator as the resonance circuit element.

UNSPSC 32121804 Crystal filter is a Commodity code that encompasses electrical components and parts used in power distribution, control systems, and utility infrastructure—though recent state and local solicitations under this code show minimal direct activity aligned with the nominal "crystal filter" category name. The code appears underutilized or misapplied in current procurement practice; recent opportunities tagged to 32121804 span relay systems, solenoid assemblies, electrical component bundles, and control panel fabrication rather than discrete filter devices. State and local buyers posting under this code include utility authorities, county governments, cities, and transit agencies. Kissimmee Utility Authority sought SEL 451 and SEL 751 protection relays (sole-source, due August 24, 2026) for SCADA integration and feeder protection. Hillsborough County Board of County Commissioners solicited Schneider Electric components on a two-year contract (ITB-26-00277, bids due June 18, 2026, estimated value $519,787.19) for standardized use in SCADA control panels, and also issued an ITB for pump station control panels and enclosures (ITB-26-00393, due September 29, 2026, estimated $3.66 million over two years). Bay County solicited a Master Lift Station Motor Control Center for the City of Bartow, and Trinity Metro (Tarrant County, Texas) established an IDIQ electrical materials contract for maintenance and emergency operations.

Recent activity concentrates in Florida (Kissimmee, Hillsborough, Bay, Tampa) and Texas (Tarrant County, City of Bartow), with secondary representation in Georgia (Gwinnett County ballasts and capacitors RFQ, due June 12, 2026). The issuing-body mix skews toward county utilities and commissions, with occasional city participation. Representative solicitations reveal that state and local buyers under this code procure mid-to-large-scale electrical infrastructure components—relays, control panels, enclosures, solenoid assemblies, and standardized electrical parts—typically for water, wastewater, utility, and transit facilities. The code's nominal scope and actual procurement activity diverge significantly; the absence of crystal filter–specific opportunities and the prevalence of relay, solenoid, and control-panel procurements suggest either systematic miscoding or that the code functions as a catch-all for miscellaneous electrical components in utility operations. Vendors should verify alignment with issuing bodies' actual technical specifications before pursuing opportunities, as nominal code titles do not consistently predict work scope.
