Hi, 

I need a clarification on Excise duty exemption to STP units.

We have been awarded a sub contract to undertake interior work (supply and installation) for an STPI unit through principal contractor, who is non STP unit.

As a sub contractor, when we procure any excisable material from the supplier for the purpose of STP units , whether the supplier is exempted from charging excise duty, being this supply is to STP unit ?. If yes, what are the documents that will be required to claim the excise duty benefit by the supplier. 

Pl clarify.
