I already made the Aus industry requirement known - see above.

If a device runs on 230 V AC, then the whole unit needs to be certified, 
even if the manufacturer has a voltage converter inside the device. If 
they put the voltage converter *outside* the device, buying it from a 
company that builds and certifies the external converter, a number of 
different devices can be run on the same converter (under its 
certification) or changes can be made to the device, all without 
triggering a recertification. That saves a hell of a lot of cost

Rod says there's more to it than that. Ok, let's see it.

Note, DC fans are more energy efficient than AC fans but energy 
efficiency is not the point here because you can wire the fans direct to 
AC mains when you have a built in converter. I have a ceiling fan here 
that is direct wired to 230 AC. Obviously it will have a converter in 
the case of the unit and, as a consequence, the entire unit will need to 
have been certified. But the fact that the fan runs on DC is not the 
point. The whole point is the use of a wall wart (plug pack) instead of 
wiring the AC direct to the unit and using a built in converter. I have 
stated it is cost and the majority of the cost savings would be in not 
having a requirement for mains certification on the device (fan), just 
on the wall wart.
