UNSPSC 25111537: Marker buoy

Marker Buoys are designed to mark the presence of the pipeline but can be used also for different type of application in the marine market. The buoy is composed by a inner core of water tight (non-absorbing) expanded closed-cell polyethylene foam.

UNSPSC 25111537 Marker buoy, a Commodity code, covers specialized aquatic monitoring and control equipment that state and local governments procure for water treatment and environmental management operations. State and local buyers under this code include water utilities, municipal treatment facilities, and special-purpose water districts that deploy buoy systems for real-time water quality monitoring, algae control, and treatment-process adjustment. The City of Tampa's David L. Tippin Water Treatment Facility exemplifies the typical buyer profile—a municipal water utility requiring integrated monitoring systems that combine sensor buoys with software-driven control capabilities to support ongoing treatment operations.

Recent activity shows concentrated procurement in the water treatment sector with limited geographic spread. The City of Tampa issued an Intent to Single Source on April 23, 2026 (due April 16, 2026) for the MPC Buoy Ultrasonic Algae Control and Monitoring System to maintain continuity with the existing LG Sonic US, LLC installation; the procurement required authorized distributor status and OEM parts certification. Sourcewell, acting as a cooperative purchasing vehicle on behalf of the State of Minnesota and multiple Washington counties (Franklin, Grant, Grays Harbor, Chelan, Yakima), posted RFP #061626 on May 12, 2026 (due June 16, 2026) for a broad Law Enforcement Equipment framework agreement with national reach, though the connection between law enforcement equipment and marker buoys is unclear and may reflect a coding mismatch in the solicitation. The code shows minimal recent activity tied directly to marker buoy procurement; most documented opportunities involve specialized water-treatment buoy systems where established vendor relationships and OEM certification requirements limit competitive entry.
