UNSPSC 12161502: Cross linking agents

UNSPSC 12161502 Cross linking agents is a Commodity code. The recent state and local activity tagged to this code does not align with cross linking agents as a product category. Instead, the opportunities span forensic DNA amplification kits, laboratory diagnostic testing services, pharmaceutical monitoring test kits, and general laboratory supplies and chemical reagents — none of which are cross linking agents in the chemical additive sense. The Maryland Environmental Service's request for liquid emulsion polymer for biosolids dewatering, the Collin County RFP for offender drug testing services, the Mississippi Department of Mental Health's sole-source FDA-cleared Clozapine test kits, and the Oregon State Police procurement for Promega PowerPlex Y23 DNA kits all represent distinct laboratory, diagnostic, or forensic testing domains. The issuing bodies include state environmental and correctional agencies, county community supervision departments, county health services, state police forensic labs, and county public health departments — a broad mix of state and local criminal justice, health, and environmental operations. The code shows little relevant recent activity aligned with its nominal scope of cross linking chemical additives.

Geographic spread spans Maryland, Texas (Collin County), Mississippi, Oregon, California (San Bernardino County), Georgia (Cobb County), and the District of Columbia across the recent postings. Representative recent opportunities include the Maryland Environmental Service's competitive sealed bid for liquid emulsion polymer (due November 16, 2026), Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services at an estimated contract value of $600,000 (proposals due July 23, 2026), Oregon State Police's sole-source notice for Promega PowerPlex Y23 forensic DNA kits at an estimated value of $250,000 over five years (protests due July 31, 2026), San Bernardino County Department of Public Health's ITB for laboratory supplies including culture media, stains, and reagents (due July 31, 2026), and Cobb County School District's IFB B26128 for science specimens, chemicals, and equipment with an estimated annual expenditure of $175,000 (due June 16, 2026). The mismatch between the code's chemical-additive definition and the forensic, diagnostic, and educational laboratory testing services actually being procured suggests this code is not the primary vehicle for cross linking agent procurement at the state and local level.
