UNSPSC 41151728: Mercury test system

In this classification, a Mercury test system is a device intended to measure Mercury for clinical toxicology purposes. US FDA regulates Mercury test system under 21 CFR 862.3600 and under FDA product code DPH

UNSPSC 41151728 Mercury test system is a Commodity code with minimal recent state and local procurement activity aligned to its nominal scope. The single opportunity in the dataset—Mississippi State University's sole-source notice for a Redwire Stalker Block 40 UAV (posted October 9, 2026, objections due October 23, 2026)—does not involve mercury test systems and reflects a Department of Homeland Security project requiring custom aircraft integration, not measurement or analytical testing equipment. The remaining opportunities tagged in the dataset cover unrelated scientific instruments, laboratory equipment, and materials including microscopes, spectrometers, induction furnaces, cooling systems, acoustic receivers, and early childhood learning materials. None of these solicitations involve mercury measurement, detection, or testing equipment as the code designation suggests.

The code shows no coherent procurement pattern among state universities, county governments, or state agencies over the recent period. Mississippi State University dominates the visible activity in the dataset, but its recent procurements cluster around specialized research instrumentation for materials science, agricultural technology, and advanced manufacturing—not mercury analysis or monitoring. Without recent opportunities that match the code's stated scope, the category presents limited commercial signals for vendors specializing in mercury test systems, detection instruments, or related analytical capabilities. Firms monitoring this code should track whether future activity realigns with the nominal scope or continues to reflect broad misclassification in state and local procurement systems.
