Case Note & Summary
The case involved an appeal against a common judgment of the Customs Excise and Gold (Control) Appellate Tribunal concerning the assessable value of goods manufactured by the appellants, M/s. Thermax Limited. The appellants manufactured high-pressure boilers and charged separately for pre-manufacturing and post-manufacturing services, including designing, engineering, erection, and commissioning. The Revenue issued show cause notices alleging that these charges should be included in the assessable value for excise duty purposes. The Assistant Collector confirmed some of these charges, while the Collector of Central Excise (Appeal) ruled that designing and engineering charges were includable, but not the erection and commissioning charges. The Revenue appealed to the Tribunal, which ruled in favor of including the charges. The appellants contested the inclusion of erection and commissioning charges, arguing that these should not be part of the assessable value. The Supreme Court analyzed relevant precedents, including PSI Data Systems Ltd. and Mittal Engineering Works, which established that such charges are not includable in the assessable value. The court concluded that the Tribunal's decision was incorrect and set aside the orders regarding the inclusion of installation and commissioning charges, partly allowing the appeal without costs.
