UNSPSC 42183050: Nystagmographs

In this classification, this commodity indicates a product used as an apparatus for measuring the amplitude, periodicity, and velocity of ocular movements in nystagmus, by measuring the change in the resting potential of the eye as the eye moves in a medical setting. Most nations, for tariff and trade purposes, schedule these products under HS 901811.

UNSPSC 42183050 Nystagmographs, a Commodity code, shows minimal alignment between its nominal scope and recent state and local procurement activity. The code represents diagnostic laboratory equipment for measuring eye movement, yet the recent opportunities posted under it consist of precision electrical test modules, water-quality spectrophotometers, and law-enforcement equipment — none of which fall within nystagmography's medical instrumentation domain. The mismatch suggests either miscategorization in the source records or exceptionally sparse authentic activity under the code's intended scope. State and local issuing bodies, when procurement occurs, tend to be utilities, cities, and cooperative purchasing vehicles like Sourcewell that aggregate demand across multiple jurisdictions.

Recent postings show geographic spread across Florida (Kissimmee Utility Authority in September 2026, City of Tampa in June 2026) and a multistate cooperative framework through Sourcewell based in Minnesota serving participating entities including Washington counties. The Kissimmee Utility Authority issued IFB 26046JG for a precision high-voltage capacitance and power/dissipation factor measurement module under $250,000 with a September 22, 2026 response deadline; the City of Tampa issued RFQ 26-P-00372 for a spectrophotometer replacement at its McKay Bay Waste to Energy facility with a June 12, 2026 quote deadline; and Sourcewell issued RFP #061626 for law enforcement equipment to be made available through a cooperative purchasing framework with a June 16, 2026 proposal deadline. The code does not support recent opportunities in nystagmography procurement itself and warrants verification of correct UNSPSC classification before prioritizing pursuit.
