Our client is a telecom company. It has bought capital goods from outside india and has paid customs duty on the same. He has availed cenvat credit of CVD (Additional Duty) and adjusted the amount from service tax payable. My query is if the capital goods are used as lines (telecom lines) between delhi and jammu whether cenvat credit for the whole amount will be available or not? As the lines are used both in a taxable territory and non- taxable territory.
