UNSPSC 23201100: Adsorption and ion exchange

UNSPSC 23201100 Adsorption and ion exchange, a Class code, does not align with the recent state and local contract activity tagged under it. The one recent opportunity on record — the City of Palm Bay, Florida's Invitation to Bid 19-ITB-26, posted April 13, 2026, with a bid deadline of March 17, 2026 — solicits comprehensive laboratory testing services for water, wastewater, groundwater, and industrial pretreatment program compliance monitoring. The scope encompasses 188 line items across water testing (65 items), wastewater testing (75 items), industrial pretreatment testing (8 items), and courier and sampling services, with unit prices ranging from $0 for calculated field measurements to $425 for specialized analyses such as Cryptosporidium and Giardia. The City's historical spending of $66,360 in 2024 and $95,440 in 2025 establishes the budget context. Three bids were received: Advanced Environmental Laboratories, Inc. at $80,872.00, Flowers Chemical Laboratories, Inc. at $91,775.40, and Pace Analytical Services, LLC at $107,946.10. Contractors must hold a minimum of five years of experience serving municipal water and wastewater utilities, possess Florida Department of Health Environmental Laboratory Certification Program certifications, maintain NELAP accreditation, and perform 75 percent of analytical work in a primary laboratory within one hundred miles of the City's North Regional Campus.

The code shows minimal recent activity and no evidence of state or regional scope; the single sourced opportunity reflects municipal water and wastewater laboratory testing rather than adsorption or ion exchange services. The mismatch suggests either miscoding by the issuing body or that the code does not capture meaningful state and local procurement activity in this domain. Business development professionals pursuing water utility or environmental testing contracts should verify the actual UNSPSC classifications used by target jurisdictions before investing in proposals under this code.
