"Corbus,

We don't ship


"Corbus,

We don't ship parts outside the US and Canada, but we have had some foreign customers make arrangements with freight forwarders in the US. Then we ship to them and they ship to the overseas customer. DHL does it as do others.

If you are interested in that send me an email and I can give you the name of one, or you could find one."
