What This ECCN Covers

ECCN 3A226 controls high-power direct current power supplies having both of the characteristics in the entry. High-power DC supplies of this class drive sensitive processes such as isotope separation, so they are controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.

Who needs to check this?

Makers and exporters of high-power DC power supplies for industrial, plating, and research applications.

Compliance tip

Control turns on the voltage, current, and stability thresholds in the entry — many industrial supplies fall outside. With NP among the reasons, apply Part 744 nuclear end-use diligence and verify the Country Chart.
