Custom Duty At International Airport

Dear friends,
I am coming back to India from Gulf and I want to buy gifts (watches,perfumes, sweets) for my family members and friends.
Please, guide me if any custom duty on it at our airport or what are the maximum limits for these at mumbai airport for free of custom duty.

Dear Mr. Patel,
You can get in goods worth Rs. 12,500/- free of duty in India while coming in from abroad. Regards Mashikaka

Dear Mashikaka,
As per my knowledge it is Rs 25,000/- and not Rs 12,500/-
Just recently I had been to Nigeria. While returning back to India and before landing at Bangalore Airport, airlines had given us one form to fill. In the form the value mentioned was Rs 25,000/- This amount includes all sort of articles like liquor, tobacco, electronic goods etc.
Thanks,
