Claiming refund of taxes & ed after invoicing an sez company

Hi Bhaskar,

Here your company has paid ED & slaes tax on your input  and the same input is traded to SEZ unit

1. Coming to ED paid on input,  

Your Company can  utilise CENVAT credit of ED paid if your company is a manufacturer/a service provider 

since your company is in pure trading activity you can neither utilise cenvat credit of ED paid nor you can get the refund of ED paid

2. Coming to sales tax paid on input

(i) If SEZ unit is situated within  state

Some of the states either exempt such sale intended for SEZ unit or they allow the refund of input tax paid

(ii)If SEZ unit is situated outside the state

Since are the goods are sold to SEZ unit, your company can ask SEZ unit to issue form-I in favour of your supplier so that it can be exempted CST if it is inter state sale
