Scott et al,
Ah. As we suspected, it is a regulatory mark. Who inspects?

Hi Rich,
The doc's stated purpose for the mark is as follows:
"The international efficiency marking protocol provides a system for EPS
manufacturers to designate the minimum efficiency performance of an EPS, so
that finished product manufacturers and government representatives can easily
determine a unit’s efficiency. "
Class VI is more stringent than Class V, and has been mandatory in the US since
February 2016.

If the mark is required to meet legislated efficiency requirements then it’s
likely the customs inspectors will be looking for it on imports.

Hi Scott:
Thanks for the reference. However,
“This mark does not serve as a consumer information label, but rather
demonstrates the performance of the EPS when tested to the internationally
supported test methods.”
Hmm. If the mark does not serve as a consumer information label, who is it
for? Bragging mark (to other power supply manufacturers)?
My power supply is marked “V.” This appears to be more stringent than “VI.”
True?
Best regards,
Still cynical Rich

It is an efficiency marking for external power supplies. Current US requirement
is level VI. You can download more info from the DOE here
