UNSPSC 27121813: Hydraulic classifier

Particle separator in two or more granulometric fractions regarding the settlement velocity inside a fluid.

UNSPSC 27121813 Hydraulic classifier, a Commodity code, describes equipment and machinery used in separation and classification processes. State and local governments procure hydraulic classifiers primarily through cooperative purchasing frameworks designed to serve law enforcement and public safety agencies, though the code's nominal scope encompasses industrial separation equipment used across water treatment, mining, waste management, and environmental remediation applications. Recent solicitation activity shows that state and local buyers are sourcing specialized equipment through multi-jurisdictional cooperative agreements rather than direct agency purchases, reflecting a shift toward standardized contracting terms that allow flexibility in deployment across diverse public-sector organizations. The buying entities include county governments, cities, school districts, tribal governments, and nonprofit organizations accessing equipment through cooperative purchasing vehicles.

Sourcewell, a Minnesota local government unit and service cooperative, issued RFP #061626 on May 12, 2026 to establish a law enforcement equipment contracting solution on behalf of participating entities including Franklin County, Grant County, Grays Harbor County, Chelan County, and Yakima County in Washington state, with participation available to governmental agencies, higher education institutions, K-12 school districts, nonprofit organizations, and tribal governments throughout the United States and Canada (response deadline June 16, 2026 at 3:30 p.m. Central Time through the Sourcewell Procurement Portal). The geographic activity center appears concentrated in Washington state based on the named participating counties, though the cooperative structure extends potential reach nationally and into Canada. The cooperative purchasing mechanism—allowing selected vendors to serve thousands of participating entities under a single framework agreement—suggests that vendors winning Sourcewell contracts gain access to a broad customer base across multiple jurisdictions and entity types, though no specific award values or set-aside designations are disclosed in available documentation.
