The respondent assessee is an integrated steel plant engaged in the manufacture of various excisable goods falling under Chapters 26 to 29, 70 to 73 and 84 of the Schedule of the Central Excise Tariff Act, 1985 (Tariff Act).

It was stated that initially coke and crude coke oven gas were manufactured by destructive distillation process through high temperature carbonization of Bituminous Coal in a separate unit called coke oven battery. The crude coke oven gas containing important by-products comes out as exhaust gas from the coke oven unit. The crude gas as such cannot be used as fuel as it consists of coal tar and other organic compounds which would disrupt the supply system. The crude coke oven gas is taken to another unit called product recovery plant where the crude gas is cleansed from the other major by-products namely, Naphthalene, Ammonia, Motor Spirit, Light Oil etc. and waste (coal tar) through use of MODVAT Inputs, namely, Sulphuric Acid, Wash Oil etc. The pure coal gas thus manufactured in a marketable stage portion of which is consumed by the assessee within their factory and a portion is also sold outside without payment of duty as the product was chargeable to Nil rate of duty under Chapter sub-heading 27.05.

Further, they were purified through use of Sulphuric Acid, Wash Oil (MODVAT Inputs) in the recovery plant on which credit was taken by the assessee. The coal gas has been cleared without payment of duty as it was chargeable to Nil rate of duty.

The show-cause notice stated that the total amount which ought to have been paid by the assessee come to Rs.67,32,348.00. After referring to Rule 57C(1),(5) and (9) it was stated that a reading of the rules would lead to the conclusion that a manufacturer engaged in the manufacture of both dutiable and exempted final products can neither avail of the credit of duty of inputs and pay the prescribed amount at the time of clearance of the exempted/ chargeable to Nil rate of duty final product or not both the credit of duty on inputs used in or in relation to the manufacture of exemptible/ chargeable to Nil rate of duty final produce. After referring to Rule 57CC of the said Rules it was stated that whether or not any of the said MODVAT Inputs contained in the final product, coal gas, an amount of 8% of the price of such fuel gas would be chargeable on the quantity cleared outside on sale without payment of duty. It was further alleged that the assessee had not maintained separate inventory and accounts in respect of the said inputs which were used in or in relation to manufacture of the said Nil rate of duty final product and have availed the credit of inputs used in the manufacture of both the aforesaid categories of final product; that the assessee had neither debited an amount equal to 20% or 8% of the price of the said exempted final product at the time of its clearance from the factory in terms of Rule 57CC(1) of the said Rules and thus violated Rule 57C(1) and consequently are required to pay the amount quantified.
