UNSPSC 32121802: Ceramic filter

UNSPSC 32121802 Ceramic filter (Commodity) describes electrical protection and control system components—specifically protection relays, electrical enclosures, control panels, and associated electrical parts and materials—that state and local governments procure for utility operations, water treatment and wastewater infrastructure, transit facilities, and municipal buildings. The recent opportunities block shows activity focused on replacement relays for SCADA-integrated electrical systems, fabricated control cabinets and pump station enclosures, standardized electrical component inventories for maintenance and emergency repair, and elevator/escalator systems; the nominal code name "ceramic filter" does not reflect the actual scope of current procurement under this code. Issuing bodies include utility authorities, county boards of commissioners (particularly in Florida), school districts, transit authorities, and city governments; Hillsborough County and the City of Tampa appear as repeat buyers across multiple solicitations. The work spans protection and automation relays (SEL 451 and 751 models), UL 508A-certified control panel fabrication for pump stations, ballasts and capacitors for lighting systems, Schneider Electric components for SCADA standardization, solenoids for water treatment facilities, and blanket electrical materials supply agreements for maintenance and emergency response.

Recent activity concentrates in Florida (Kissimmee Utility Authority, Hillsborough County, Bay County, Tampa, Gwinnett County in Georgia, and Tarrant County transit and municipal authorities in Texas). Representative recent opportunities include Kissimmee Utility Authority's sole-source IFB for SEL 451 and 751 Protection Relays (solicitation SS26054SH, due August 24, 2026), Hillsborough County's ITB for pump station control panels and enclosures with a $3.66 million estimated value and September 29, 2026 deadline (ITB2600393), Northside Independent School District's sealed-bid IFB for electronic equipment parts, repairs, and services (IFB2026118, due September 24, 2026), Trinity Metro's IDIQ contract for electrical materials across Tarrant County facilities (IFB26T035, due August 20, 2026), and Gwinnett County's competitive quote for ballasts and capacitors on annual contract (due June 12, 2026). The code shows consistent activity from utility and county infrastructure organizations seeking replacement components that integrate with existing SCADA, protection, and control systems without requiring system redesign.
