CENVAT is an input duty credit scheme designed to reimburse manufacturers for duties paid on inputs. It prevents cascading of duties on final products. CENVAT covers most inputs and capital goods, and applies across India except Jammu and Kashmir. Under CENVAT, manufacturers can claim credit for eligible duties paid when clearing final products. The CENVAT Credit Rules outline provisions for availing, transferring, and recovering credit, as well as penalties for non-compliance.
