UNSPSC 12164400: Non emulsifiers

UNSPSC 12164400 Non-emulsifiers, a Class code, encompasses chemical treatment agents and additives used in municipal water treatment and wastewater operations, including calcium oxide (quicklime), hydrated lime, acids (hydrochloric, citric, muriatic), sodium hypochlorite, hydrogen peroxide, and related water-treatment chemicals delivered on regular or emergency supply contracts. State and local water utilities, water resource recovery districts, and municipal water departments dominate procurement activity under this code, with school districts and specialized districts occasionally buying pool chemicals within this classification; repeat buyers include municipal water treatment plants and city public utilities departments in Florida, Georgia, and the broader Southeast.

Recent solicitations show robust competitive activity across ITBs and RFQs centered on firm, multi-year supply agreements for NSF-certified chemicals with delivery requirements typically met within 72 hours of order. Representative recent opportunities include the City of St. Petersburg IFB-26-344 for calcium oxide delivery to the COSME Water Treatment Plant (bids due October 29, 2026), the School Board of Pinellas County RFQ 25AM018 for swimming pool chemicals across five school locations (bid deadline February 11, 2026), the City of Phoenix IFB-26-0104 for hydrochloric and citric acid through a five-year term (proposals due October 16, 2025), the City of Cocoa ITB B2617COC for liquid sodium hypochlorite with 5% local preference for Brevard County contractors (bids due September 23, 2026), and the City of Cartersville Water Department IFB for treatment chemicals to two facilities awarded as individual line items (bids due October 30, 2026). Activity concentrates in Florida and Georgia with secondary presence in Arizona, Connecticut, and Oregon; vendor set-asides vary by jurisdiction—some solicitations include SBE/MBE/WBE participation requirements or local preference provisions, while others remain unrestricted. Sole-source procurements for proprietary equipment maintenance (such as lime slaking systems from Chemco Systems and separator parts from Andritz Separation) also appear under this code when tied to chemical supply or system-specific consumables.
