UNSPSC 42203907: Microbeam alpha particle and proton irradiation systems

In this classification, this commodity indicates a product used as a device that generates is a narrow beam of alpha particle or proton radiation, of micrometer or sub-micrometer dimensions in a medical setting. Most nations, for tariff and trade purposes, schedule these products under HS 901819.

UNSPSC 42203907 Microbeam alpha particle and proton irradiation systems is a Commodity code covering specialized particle-beam equipment used for materials research, medical device testing, and precision material modification. State and local governments rarely procure this equipment directly; when they do, purchases are driven by university physics departments, research institutions, and medical facilities within state university systems or state-operated teaching hospitals. The work involves sourcing complete irradiation systems or beam-delivery subsystems capable of targeting materials at the micrometer scale using alpha particles or protons, typically for semiconductor failure analysis, cellular damage studies, or ion-implantation applications.

No recent state and local contract opportunities appear under this code. The narrowly specialized nature of microbeam irradiation systems — requiring advanced nuclear physics expertise, regulatory compliance with radiation safety codes, and end-user demand concentrated in graduate research labs and specialized medical centers — limits procurement frequency and visibility in state and local RFP, RFQ, IFB, or ITB channels. Buyers in this space typically source through federal research grants, university capital equipment budgets, or specialized scientific-equipment vendors rather than competitive public procurement processes.
