Well, this is another thread gone haywire.
Central Excise duty is on manufacturer. If the process underaken by a job worker amounts to manufacture- duty is payable. The manufacturer is required to pay the duty. In this case job worker is the manufacturer. However, to help small job worker, such duty liability has been shifted to the principal manufacturer under botification 214/86 as well as Cenvat Credit Rules. Both the procudure requires that after job work the material must return to the principal manufacturer, where it wil be used in further manufature of final products on which duty will be paid.
It must be understood that primary liability of duty payment is on the person doing manufacturing (in this case it may be job worker), so it is necessary in the interest of job worker to ensure that the procedures are scrpulously followed, so that no future liability arises.
It is further to be noted that now job work, which does not amount to manufacture attarcts service tax, under the head of business auxiliary services.
