Manufacture

Hello sir, this is Prasanth
Regarding your query the production of iron wires is considered as manufacturing activity under section 2(f) of Central Excise Act,1944 hence registration for excise is needed however there is Threshold limit of 1.5crores turnover ,it is complusory to register only if such limit exceeds.
General rate of Excise duty is 12.5% can also be able to claim cenvat credit.
Hope this may solve your query😉

Thanks Prasanth
