번역 - 러시아어-영어 - безвозмездный перевод денег

'безвозмездный' is the key word, 'money transfer' are merely the context.

is it possible to tie here up 'gratis' somehow?

we say "free" in English in this case, have a look at this link for example:
http://www.icicibank.com/Pfsuser/icicibank/ibank-nri/nrinewversion/moneytransfers_other_webwire.htm
(see items 6,7,

dear Car0le, let me thank you for your efforts, but i still in doubt about the phrase.

look at citation: "Free money transfers to accounts at over 630 ICICI Bank branches"
here we can see the bank offering money transfer at no charge, right? (indeed, it's own branches cost nothing)
ps: hint! - 'бесплатный перевод' is russian equivalent for the example

my case is different, transfer comission fee applies, but the money is given 'gratis', you see?
now we need no spoken form, rather written, official. (epistolar?)

moreover, how can one distinguish between two cases, undoubtfully different, by plain and simple (ve-ery basic )
'free money tranfer')

pps: machine translated phrase: 'Gratuitous remittance'
russian note about such transfer: "Для этого клиенту достаточно указать в заявлении на перевод, что сделка носит безвозмездный и невозвратный характер."
