The supermarket group has beaten Tesco and US retailer Wal-Mart into the country by teaming up with Hypercity, India's first hypermarket, to sell more than 200 own label products at Hypercity's first store in Mumbai.
Waitrose has been given a dedicated area of the 120,000 sq ft store, with products on offer including conserves, biscuits, oils, sauces and beauty ranges.
A spokeswoman for Waitrose said that it currently supplied own label products to supermarkets in 18 countries outside the UK including the Far East and the Middle East.
"The decision to export to Hypercity fits with this strategy," she said, adding that Waitrose planned to supply further Hypercity stores in Ahmedabad and Delhi later this year.
Currently, Indian state rules do not allow foreign direct investment in grocery retail outlets.
