The newly-launched iPhone models-- 6S and 6S plus --were seized over the past two weeks, a Customs official said.
"These high-end models have been launched in some countries and are yet to be launched in India," the official said.
The passengers are trying to smuggle these phones to be sold in the grey market here.
The phones have been seized from fliers coming from Singapore, Bangkok, Hong Kong, Istanbul, London, Dubai and Johannesburg.
Officials said if the passenger is apprehended after passing through the green channel, then he becomes liable to pay fine, penalty in addition to the customs duty, while passengers carrying iPhones in commercial quantity are liable to be arrested.
