ECCN 3A225

NPAT

Frequency changers (a.k.a. converters or inverters) and generators, except those subject to the export licensing authority of the Nuclear Regulatory Commission (see 10 CFR part 110), that are usable as a variable frequency or fixed frequency motor drive and have all of the characteristics described in this ECCN .

What This ECCN Covers

ECCN 3A225 controls frequency changers (also called converters or inverters), and generators, other than those specified elsewhere, having the characteristics in the entry. High-performance frequency changers can drive gas-centrifuge motors, so they are controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.

Who needs to check this?

Makers and exporters of high-frequency drives, converters, and inverters for industrial motors and process equipment.

Compliance tip

Control turns on the output frequency, power, and stability parameters in the entry — common variable-frequency drives may fall outside. With NP among the reasons, apply Part 744 nuclear end-use diligence and verify the Country Chart.
