Dear Sir, Slag generated during manufacture of iron and steel products is classifiable under heading 2618 or 2619 of Central Excise Tariff depending upon as to whether slag is granualized or not. Both headings have a standard rate of duty of 12.5%.
2. However, if you search TMI, you will find catena of decisions where slag arising during course of such manufacture has been held to be non- excisable. One such decision is that of Hariyana Steel and Power reported at 2015 (11) TMI 771 - CESTAT BANGALORE.
3. Notwithstanding that such slag is non-excisable, if you remove this on consideration, you have to follow procedure prescribed under Rule 6 of Cenvat Credit Rules, 2004 because for purpose this Rule, exempted goods now include non-excisable goods.
