2. Briefly stated the facts are:-

The appellants are manufacturers of heavy electrical equipment and machinery which they make as per the specific requirements of customers. The Terms and Conditions of sale to the customer contains a warranty clause which provides for free replacement of defective parts within a period of 12 months to 18 months. At the time of sale the appellants charge 2.5%, of the factory cost, as a "complaint reserve". This element is added to the price. It is not disputed that the excise duty is paid on the total amount charged to the customer including this element of 2.5% complaint reserve. At a subsequent stage, on some occasions, parts have to be replaced by the appellants during the warranty period. The question for consideration is whether excise duty is payable on the parts which are replaced during the warranty period. Both the Collector and the Tribunal have held that excise duty was payable. Hence these appeals.
