Apple's cheaper iPhone models (SE and 6S) are already made in India, but this is the first time newer models, like the X family, will be produced there.
Though the Chennai plant has been shut since 2015, Foxconn's Sri City facility on the Tamil Nadu-Andhra Pradesh border has been manufacturing handsets for Xiaomi, Nokia and Gionee.
While Foxconn was not new to India, it had made a decision to manufacture some of Apple's most expensive models, such as the iPhone X series, in the Southern Asian country beginning in 2019.
Tamil Nadu Industries Minister M C Sampath told Reuters that Foxconn had lined up a Rs 25 billion ($356 million) investment at its Sriperumbudur plant.
Apple's decision to manufacture iPhones in India likely stems from the ramifications of the ongoing trade war between the US and China, started by President Donald Trump earlier this year.
Apple did not immediately respond to a Fortune request for comment on the report.
Reports from the Consumer Intelligence Research Partners (CIRP) today, has shown how impressive iPhones have sold compared to other phones. This number was 12 percent a year ago after iPhone 8 and 8 Plus were released in September 2017 and 11 percent when the revolutionary iPhone X was shipped in November 2017.
It's also just 2 percent ahead of the share last year's iPhone X had grabbed - despite the fact that prices for the X started at $999.
Complete details about Apple's deal with Foxconn are not yet clear. With that said, it's unclear if this means all production of iPhones have been shifted from China to India, or if the Indian manufacturing line is merely acting as a supplement.
Foxconn, the world's biggest electronics contract manufacturer, is considering setting up a factory in Vietnam, Vietnamese state media reported this month.
Foxconn has previously admitted the China-U.S. trade spat was its biggest challenge and that its senior executives were making plans to counter the impact.
