Can you please provide country of origin of this product? I am trying to import it. and it is one of custom requirements.

Molex makes things all over the world, and the same items can be made multiple places. So, it is pretty much impossible to say where a product was made. .

what is the voltage rating?

350 V go to molex or search for 0430250408

What is the pitch of these connectors?

Pitch - Mating Interface 3.00mm I posted a copy of the data sheet on my review under MS. Here is the Molex Part Number: 0430250408 you can search and find more information

Can these pins be removed with a de-pinning tool or are they stuck for good once the pin is plugged in?

I think they can. I wish I had the tool to do that, I just used pins and pointed objects. Not the easiest, but you can get them out.
