Now is there anyway to import a hardware wallet to any country where crypto currencies are illegal ?
No - unless you really want to deal with the authorities who can arrest you for illegal activity. You may be able to import a hardware wallet into a country where crypto is completely banned - but you may need to work with some corrupt government authorities including high-ranking government officials or the police.
But what's your goal? If you want to profit from selling hardware wallets - then trade with countries that don't completely ban crypto instead of threatening yourself with the law in force.
