Cosmic Dye Chemical v. Collector of Central Excis

The appellant, Cosmic Dye Chemical, manufactured two products:

1. Rapidogens, which were fully exempt from excise duty under Notification No. 180/61.
2. Naphthol ASG, which was dutiable.

The assessee claimed the benefit of the Small Scale Industry exemption under Notification No. 71/78 for Naphthol ASG by declaring that the aggregate value of excisable goods manufactured during the previous financial year was below the prescribed exemption limit.
