RE-EXPORT AND RE-IMPORT

Dear All,

I am working in a Battery Manufacturing Co. two months back we have  Exported 400 nos of batteries. But  now we came to know among 400 nos of batteries 40 has been rejected. So Importer decided to send back the rejected batteries.

Now  if we  import  the rejected 40 nos of batteries then we have to pay all duties. To avoid this duty matter how can we do import that rejected batteries. Kindly advice me.

Thanks and regards,

R.Dutta
