Captive use exemption turns on proof of actual manufacture-related consumption, with remand for fresh determination of eligible quantity.

Oxygen gas captively consumed in manufacturing iron and steel products was eligible for exemption only to the extent actual use for the specified exempted purpose was proved. The exemption notification required the Assistant Collector to be satisfied on that factual user, so the precise quantity qualifying for relief had to be determined first. Because that factual ascertainment had not been properly undertaken, the order was set aside and the matter remanded for fresh determination of the exempt quantity, with consequential relief confined to the amount found eligible. The higher valuation issue was left open.

Issues: Whether oxygen gas captively consumed in the manufacture of iron and steel products was entitled to exemption under the relevant notification, and whether the quantity qualifying for exemption required fresh determination by the Assistant Collector.

Analysis: The exemption notification under Rule 8(1) of the Central Excise Rules, 1944 exempted oxygen gas used in the manufacture of iron in crude form, steel ingots and iron or steel products, subject to the Assistant Collector being satisfied that the gas had been so used. The appellants manufactured the specified goods, but the precise quantity of oxygen gas captively consumed for the exempted purpose had to be ascertained. Since that factual determination had not been properly undertaken, the matter required reconsideration by the Assistant Collector. The question of valuation at the higher rate was left open.

Conclusion: The exemption was available to the extent oxygen gas was proved to have been captively consumed for the specified manufacture, and the matter was remanded for determination of that quantity.

Final Conclusion: The order under appeal was set aside and the dispute was sent back for fresh determination of the extent of exemption, with consequential relief limited to the quantity found eligible.

Ratio Decidendi: Where exemption depends on actual use of goods for a specified manufacturing purpose, the authority must first determine that factual user before denying or granting the exemption for captive consumption.
