Amit Agarwal, the India head of Amazon, said in an interview on Friday that groceries and goods such as creams, soaps and cleaning products, were already the largest product category on Amazon in terms of number of units sold in India.

"I would not speculate on when we would launch AmazonFresh but, absolutely, if you ask me the next five years of vision - from your avocados to your potatoes, and your meat to your ice cream - we'll deliver everything to you in two hours," he said.

AmazonFresh, which launched more than a decade ago in the US market, is the company's flagship fresh grocery delivery service. In India, Amazon currently offers some groceries via a service named Pantry. It has also tied up with local vendors in four cities for Amazon Now, which promises two-hour deliveries.

"Probably in the next five years groceries and consumables would be more than half of our business," he told Reuters.

Agarwal said Amazon had already started experimenting with a few fresh groceries in India, already home to its largest active customer base outside of the United States.

India's e-commerce market is tipped to grow to $200 billion in a decade, according to Morgan Stanley, as cheap mobile data makes online shopping increasingly accessible.

And Amazon, which already has over 100 million registered users in India, is looking to cash-in on the opportunity.

"We want to get the next hundred million customers shopping with us," said Agarwal, adding that Amazon plans to woo new clients with product exchange and staggered payment offerings.
