oh no definitely not. For company product aggregate.

'All multi-brand retail operations with FDI must be locally sourced with at least 30 percent of the value of manufactured/processed products from Indian “small industries,” which have a total investment in plant and machinery not exceeding U.S. $1 million. '

Quite a tall order still.

But then how can you know how much will sell ahead of time?

Suppose I have exactly two products, one fully sourced from India, one sourced elsewhere. The legality depends on whether the first sells more than a 7:3 ratio over the second, which can't be determined before actually selling.

You're right and I don't know the details. But I assume you'd have to provide plausible sales projection data to the authority, and then have periodic audits.

These FDI restrictions were placed for multi-brand retail stores like Walmart.

I guess Apple stores are considered multi-brand because they sell some products from other brands as well.

These restrictions are only for foreign companies. An Indian company can sell 100% imported products without any restrictions, but they are required to pay import duty.
