Thank you very much AferditaH
Sorry my bad!
I would like to do tax refund for Swiss goods at Munich Airport.
Because Switzerland is not in EU then I have to get customs stamp on my tax refund form before leaving Switzerland to do tax refund at Munich Airport.
So I would like to know that is it possible to get customs stamp on the train (or train station) from Zürich HB to München Hbf?
Best regards,
Pruchya K
