Sorry you've had no response to this. We don't have any information on this exact routing.
I suggest you try Air India Cargo, as we have had recommendations from some travellers using them from Delhi to Bangkok:
Air India Cargo - Chennai/Madras, Chennai/Madras, Tel: (44) 234 7059/60, (44) 234 6871, Fax: (44) 234 7057.
Next I would try Malaysian Airlines Cargo:
CARGO SALES MANAGER
Tel : 91 44 4349037
91 44 4340558
Fax : 91 44 4349958
498 Anna Salai
Karamuttu Centre Tenampet
We would suggest air shipping to Malaysia rather than Vietnam, simply because Malaysia is more developed and is a travel destination, so less likely to have difficulties with customs (assuming you have a carnet anyway in order to get into India).
We would not recommend shipping by sea over this route, both due to the time factor and risk.
Good luck and safe travels!
