Our company imports machines and mould from China which comes under the Customs tarrif code 84543090. The normal BCD is 7.5%, CVD 10% Cess 2%, S&H Cess 1% and Addl Duty 4%. Right now we are planning to import the same items from Vietnam. As India is having a free trade agreement with Vietnam, Will I get any concession on my import duty? If so what are the documents required to claim the same.
