The thing that I didn't understand, you mean that they banned Bitcoin Hardware Wallet and their customs didn't allow to import HW in India but they had a local official retailer shop that you can purchase Hardware Wallet right? So, how these merchants got a Hardware Wallet bringing inside their country?
If the import of hardware wallets is banned, then it probably applies to ordinary people and to importers - does it make any sense to allow the sale through intermediaries, and to ban the import?
This whole situation is actually still completely unconfirmed, there is no official announcement of Indian customs. In the end, all this can only be the result of some rumor, and there has been too much of that in India in recent years.
Here, it must be stressed that the veracity of this claim was still in question at press time, especially since no customers had actually come forward to claim anything of this sort. In fact, no official notification or circular from any government agency asserting a ban on Bitcoin wallet imports had been found either.
