UNSPSC 39122328: Mercury relay

UNSPSC 39122328 Mercury relay is a Commodity code. State and local governments buy mercury float switches—control devices that trigger pump operations at predetermined liquid levels in wells, lift stations, and water treatment facilities—under this code. The Hillsborough County Water Resources Department's recent ITB for mercury float switches (ITB-26-00138, due March 2, 2026) exemplifies the work: the Department sought Type S and Type P float switches in standard and mini configurations, UL-listed, priced per unit with delivery to county warehouse locations. This code also captures broader electrical relay and switching equipment used in municipal water systems, wastewater treatment, and facility automation. Issuing bodies are primarily water utilities and municipal departments managing pumping and treatment infrastructure; Hillsborough County Water Resources appears as a repeat buyer in the recent opportunities block.

Recent activity concentrates in Florida, with Hillsborough County Water Resources Department driving solicitations. Geographic spread is narrow in the source records; no comparable recent mercury relay solicitations from other states or jurisdictions are present. The code shows modest but consistent procurement activity tied to water infrastructure maintenance and replacement cycles. Hillsborough County's ITB-26-00138 (due March 2, 2026, estimated value $60,000 over two years) is the most directly relevant recent opportunity, seeking suppliers with proven track records providing mercury float switches for wells and lift stations. Award will be made to the lowest responsive and responsible bidder on all line items, with a two-year term and CPI-U-based price adjustments permitted after year one.
