UNSPSC 39122102: Tap changer

Devices that regulate the functioning of transformers

UNSPSC 39122102 Tap changer (Commodity) shows minimal relevant recent activity in state and local procurement. The code nominally describes electrical switching devices, yet the recent opportunities posted under this classification consist almost entirely of Variable Frequency Drive (VFD) procurements—repair, replacement, and maintenance services for motors and industrial equipment—alongside unrelated work such as tennis center reconstruction and water treatment facility upgrades. The mismatch between the code's intended scope and the work actually solicited suggests either consistent miscoding at the issuing jurisdictions or that tap changers themselves are not a significant category of state and local purchase activity at present.

The few opportunities that do appear under this code reflect VFD work across multiple state and local jurisdictions: the Eastern Municipal Water District (EMWD) in Riverside County, California seeking three 500-horsepower VFDs through RFB 3921 (due April 30, 2026); the City of Phoenix Water Services Department pursuing a five-year VFD supply contract through IFB 26-0087 (due September 15, 2025); the Greater Orlando Aviation Authority soliciting VFD repair and replacement services through RFP 26-414 (due March 31, 2026); and the City of Tampa issuing single-source procurements to Stan Weaver & Company for ABB VFD products and maintenance services. Activity centers in California (EMWD, Phoenix), Florida (Tampa, Orlando), Georgia (Gwinnett County), and Washington State (Department of Ecology). The Washington Department of Ecology's electrical maintenance services contract (IFB 2618 ADM, due July 20, 2026) includes switchboard and transformer preventative maintenance but emphasizes VFD and controls work. Without clearer evidence that tap changer hardware itself is being actively procured, this code presents substantial risk of pursuing misclassified opportunities that fall outside the intended commodity scope.
