Hello,
      Imported dorji LoRa DRF 1278 modules from Tindie for $32/pair for transmitter . Ordered on 11 Jan 16 & reached bangalore on 2 Feb 16.
No custom charges . Delivered through India Post.

Just sharing the info, might be useful for other members.

I don't think a standalone transceiver is going to attract customs attention. Only if its a end user  radio then they will ask for WPC noc. I am no expert. Maybe someone can enlighten us
