This is a matter of a Manufacturing Company's Export Sales as per following:
1. An Export/Commercial Invoice made and exported on 07.11.2009. Two items A & B were exported @Rs.1000/- & 2000/- respectively. But the rate of B was 1000/- only, hence an amount of Rs.1000/- charged in excess by mistake.
2. The foreign buyer is a regular buyer and further same material is to be sent soon.
3. Is there a provision in Customs and FEMA and can the rate/amount be adjusted in the next invoice. If so what is the procedure for the same to avoid any procedural problem for the Export for both the transactions.
