UNSPSC 81102600: Sampling services

UNSPSC 81102600 Sampling services is a Class code covering the collection, preparation, and analysis of material samples across environmental, water quality, hazardous materials, and construction contexts. State and local governments procure sampling services primarily to support environmental compliance, remediation oversight, regulatory reporting, and infrastructure quality assurance. Recent solicitations show state environmental agencies, water utilities, county waste management departments, and municipal public works divisions issuing RFPs, RFQs, and IFBs for field sampling of water, soil, groundwater, hazardous materials, and building materials, with contract terms typically spanning one to five years on a task-order or project basis.

Activity under the code concentrates in California, Texas, Minnesota, Florida, and Georgia, with particular intensity in California's environmental and transportation sectors. The State of Minnesota issued an RFB (due June 29, 2026) for laboratory testing of compounds toxic to honeybees; the California Department of Transportation (Caltrans) posted an IFB (due June 30, 2026) for wash rack sump sampling and cleaning services across nine counties plus Humboldt County, with a 3% mandatory DVBE requirement and a 5% SB preference; the Texas Commission on Environmental Quality issued an RFQ (due June 15, 2026) for Superfund engineering services including field sampling at remediation sites; and Caltrans issued a certified SB/DVBE-only IFPQ (due June 19, 2026) for asbestos and lead surveys and sampling in Los Angeles and Ventura counties, estimated to exceed $5,000 but remain under $250,000. The California Environmental Protection Agency's OEHHA posted an IFB (due May 29, 2026) for water sampling supporting microplastics research, budgeted at $49,999; the Long Beach Public Utilities Department awarded multi-provider contracts for professional laboratory services at approximately $130,000 annually with a three-year ceiling of $600,000. Additional sampling-related opportunities include Tampa Bay Water's as-needed engineering RFP (due April 14, 2026) encompassing water quality studies and sampling, and Pasco County's as-needed environmental services RFQ (due April 14, 2026) including water quality studies and sampling. The code shows sustained demand from state environmental agencies, transportation departments, regional water authorities, and municipal utilities, with heightened activity in California and competitive procurement pathways favoring established environmental and engineering firms with laboratory accreditations (ELAP, NVLAP, CAC certifications) and prior public-sector experience.
