What are options to recover custom duty?

Hi,

I am in process of importing Metal scrap - Stainless Steel (HS code 7204).

Customs duty breakdown:

Basic duty: 2.5%

CVD: 12 %

Ed Cess: 3 %

SPl. CVD : 4 %

This all together comes around 20%.

Since this metal scrap will be used as raw material for manufacturing our final product. I would like to know how much of these 20% paid as import custom duties we can recover back from end customers etc?

I appreciate your comments.
