Before issuance of ban on bitcoin exchanges, bitmain had no shipping problems.
If you are sure india was listed as supported country before, then probably bitmain has got restrictions on their sales.
I doubt your order may take longer time than usual or it may be kept in delay.
Wait for some time until their support team verifies they have no obstacles in shipping to your country.
Bro are you sure, there was many conflict when bitcoin has been banned in China. I have heard the bitmain official site is not produces and deliver the products in this time. Most of the people now buying antminer series miner in the ebay and Amazon now.
