Amazon paid a record stamp duty of Rs 1.3 billion—the most ever paid for a single transaction.

Kalpataru purchased nearly 70 acre in Thane's Balkum neighbourhood from Clariant Chemicals and its subsidiary Color Chem in two separate transactions in 2004 and 2010 for a total of around Rs 3 billion.

On a portion of the remaining land, Kalpataru is developing the premium residential project, Paramount. Amazon Data Services India intends to build a hyperscale data centre on the property.
