UNSPSC 71112103: Density lithology nuclear logging services

Measurements of the macroscopic content of minerals.

UNSPSC 71112103 Density lithology nuclear logging services is a Commodity code that shows no relevant recent state and local procurement activity. The recent opportunities tagged to this code—a landfill gas collection system expansion (Dalton-Whitfield Solid Waste Authority, Georgia, ITB due May 21, 2026), park irrigation improvements (City of DeBary, Florida), a digester gas utilization project (Eastern Municipal Water District, California, RFP due April 14, 2026), and city manager executive search services (City of College Park, Georgia, RFP due February 18, 2026)—are construction, infrastructure, and professional services work unrelated to nuclear density or lithology logging. The code's nominal scope covers subsurface characterization through nuclear measurement techniques, a specialty service typically engaged for geological assessment or resource evaluation; none of the recent opportunities involve such work.

The tagging mismatch suggests either systematic miscoding in the source data or that state and local procurement offices are not actively soliciting density lithology nuclear logging services under this code at present. Firms pursuing this specialty should monitor for opportunities under related geotechnical investigation or environmental assessment codes, or contact issuing bodies directly to understand how they classify subsurface characterization work. No decision signal on market activity or buyer concentration is available from this code's recent record.
