I totally would differ on this 36% duty thing, though the official word out is 36% DUTY is charged it all depends on how well you can plead with the custom officer.
From my experience of travel between the Middle East and India I can still see people bringing in TV, but still not paying entirely the 36% duty. My last flight itself had 3 people bringing in TV's. First of all there is a lot of price hunting that you have to do in Dubai, to get the best offer. Walking into the Mall of the Emirates or Sharaf DG, LULU, just aint going to fetch the best deals. You can get a clue of the approximate pricing you might have to look into. If there are good offers at LULU and Carrefour, at the time your friend is buying then its a good bargain. Mostly they have stopped International warranties.
Just to make it clear what I want to convey by an example tactic my friend employed. He brought a 40" Samsung TV, and put it into a LG 32" box. The TV went in smoothly and he put in a lot of styrofoam particles. The price at which he got the TV is 20K. He lands into India and pleads with the custom officer, saying sir this is my one time dream and being slogging out hard, i'm a labourer worker and dont have much to surrender, also totally goes to the extend of being sober. Finally the officer ask him to pay a duty of 5k for the TV.
Totally ended up paying 25k. Saved another 25-30k of the market price. He employed the same tactic twice, which really surprised me and guess what it, worked!!
