UNSPSC 25173118: Distance Measuring Equipment (DME)

Distance measuring equipment (DME) is a system requiring both aircraft-installed and ground-based equipment, with the latter normally co-located with a VHF omnidirectional radio range (VOR) or, sometimes, an instrument landing system (ILS). It provides the pilot with the slant-range distance to the DME transmitter.

UNSPSC 25173118 Distance Measuring Equipment (DME), a Commodity code, does not align with recent state and local procurement activity. The source records identify no active solicitations for distance measuring equipment under this code. Instead, the recent opportunities tagged to this UNSPSC involve water and wastewater infrastructure, process instrumentation, pressure gauges, atmospheric monitoring systems, laboratory services, alarm monitoring, and miscellaneous trade labor and facility services—none of which constitute distance measuring equipment or its measurement functions.

The mismatch between code and scope reflects inconsistent UNSPSC classification in state and local procurement databases. No issuing bodies, geographic regions, representative contract opportunities, or decision-relevant activity supports pursuit of this code. State and local procurement professionals should verify classification before investing time in this category; the tag appears to be a data-quality error rather than an indicator of actual market demand for DME.
