I checked with custom. They said that it is impossible that 160xxxxxx is not found since HsCood is common in the world. Are you sure that you have not found this number? They said that we cannot import if we do not have this number.
I have asked the custom and they say that the HsCood is a common world standard so I think you must be able to find 160xxxxxx. Can't you really find this number? The custom says without the number we will not be able to import.
