This letter from Malik Polychem Ltd. to Keil India Engineering Private Ltd. discusses additional costs for finishing work on mixing vessels. The purchase order from Keil required a finish that was not originally included in the scope. The additional cost per vessel would be Rs. 60,000 for a 6 cubic meter vessel and Rs. 80,000 for a 10 cubic meter vessel. Malik requests confirmation from Keil on the additional costs.
