We had ordered plastic molds from China and we are charged excise duty + additional 4% CVD. There was no manufacturing then why excise duty+ why CVD is charged?
CVD: Any article imported into India is liable to CVD (in addition to BCD) equal to excise duty for the time being leviable on a like article if produced/manufactured (could be or capable of being produced/manufactured) in India.
SAD: It is leviable @ 4% in addition to basic customs duty and CVD.
Hence I assume, CVD and SAD has been levied in your case
