Excise duty refund for trading companies

Hi,

We have a query based on Excise duty refund. Is there any provision for excise duty refund for Trading companies?

This is how the scenario would be: We are a trading company having central Excise registration. We paid excise duty to our supplier but we do not collect it from our buyer who is a manufacturer. Is there anything like we can get refund of excise duty if we show pollution board certificate of the manufacturer which proves that they will use this to manufacture a product which would be exciseable? Thanks.
