UNSPSC 12161705: Basic buffers

UNSPSC 12161705 Basic buffers, a Commodity code, encompasses treatment chemicals and related specialty materials that state and local water and wastewater utilities procure to maintain operational systems, evidenced by recent solicitations seeking calcium oxide (lime), sodium hypochlorite, hydrochloric acid, hydrated lime, hydrogen peroxide, and lime slurry for water treatment plants and recovery facilities. The issuing bodies are predominantly municipal water and wastewater departments and special-purpose water districts, with scattered school district swimming pool chemical procurements; repeat buyers include the City of Holly Hill, Florida (sole-source notices for lime slaking systems and belt press replacement parts), the City of St. Petersburg (calcium oxide for bulk storage and distribution), and multiple Georgia municipalities. Solicitations range from competitive ITBs and RFQs with firm pricing and delivery requirements to sole-source procurements for proprietary equipment-specific replacement parts and authorized service, reflecting both commodity-level commodity purchasing and specialized OEM-dependent maintenance.

Recent activity concentrates in Florida (St. Petersburg, Holly Hill, Cocoa, Sarasota County, Jackson) and Georgia (Gwinnett County, Cartersville, Valdosta, Griffin), with additional solicitations from Arizona (Phoenix), Oregon (Clean Water Services district), Connecticut (Meriden), and school districts in Pinellas County, Florida, and Tucson, Arizona. Representative recent opportunities include the City of St. Petersburg's IFB-26-344 for calcium oxide delivery to the COSME Water Treatment Plant (1,800 dry tons annually, bids due October 29, 2026, with SBE/MBE/WBE participation requirements), the School Board of Pinellas County's RFQ for swimming pool chemicals to five school locations (estimated annual value $35,000, bids due February 11, 2026), the City of Cocoa's ITB B2617COC for liquid sodium hypochlorite to six water and wastewater facilities (bids due September 23, 2026, with 5% local preference for Brevard County contractors), and Clean Water Services' ITB for hydrated lime delivery to three Oregon water recovery facilities (bids due September 30, 2026). Sole-source procurements for proprietary lime slaking systems and belt press replacement parts from Chemco Systems LP and Andritz Separation Inc. signal that replacement-parts sourcing within this code often bypasses competitive bidding.
