Purchase from Country A and supply it to Country B without bringing it to India - Customs - Exim - SEZ

Dear Experts, I'm buying a material from one country, say Germany. I want to sell it to my customer in another country, say Dubai. Normally, customs should be paid if I import it to India from Germany and then export it to Dubai from India. Since the customs duty that I'm paying during the import getting added to my cost I'm not able to supply it to at a competitive price to my customer is Dubai. Suppose, if I directly supply the materials from Germany to Dubai (i.e., without bringing it to India) can I avoid Customs duty? What would be its Pros and Cons? Thank You.
