Crude iron tariff classification barred double excise levy on iron castings made before 1-8-1983.

The tariff scheme treated pig iron, iron castings and other crude forms of iron as a single commodity before 1-8-1983, while separate iron or steel products fell under a different entry. On that construction, converting old iron scrap and pig iron into iron castings did not amount to a fresh dutiable event where the raw material had already suffered excise duty. The exemption notification did not require detailed examination once the tariff entries were read in favour of the assessee. Accordingly, no excise duty was payable on the iron castings manufactured before 1-8-1983, and no L4 licence was required for that period.

Issues: Whether iron castings manufactured from old iron scrap and pig iron were liable to excise duty and whether the appellants were required to take out an L4 licence prior to 1-8-1983.

Analysis: Prior to 1-8-1983, Item 25 treated iron in any crude form, including pig iron and iron castings, as one commodity, while Item 26AA separately dealt with iron or steel products. The raw materials used by the appellants had already suffered excise duty, and the manufacture of iron castings from such crude iron did not justify a second levy at another stage. The scheme of the tariff did not support treating the conversion of one crude form of iron into another crude form as a separately dutiable event, and the exemption notification did not need to be examined in detail once the tariff entries themselves were construed in favour of the appellants.

Conclusion: The appellants were not liable to pay excise duty on the iron castings manufactured by them prior to 1-8-1983 and were not obliged to take out an L4 licence.

Final Conclusion: The writ appeal succeeded to the extent that the earlier view against the appellants was set aside for the period before 1-8-1983, with no order as to costs.

Ratio Decidendi: Where the tariff treats crude iron and its basic forms as one commodity and the raw material has already suffered duty, manufacture of another crude form from it does not attract a further excise levy absent a clear charging provision.
