Time limit for submit of proof of Export

[Asked by Guest]

Dear Sir,
Can any one clarify me that what is the time limit for submission of Proof of export to the excise department.

As my knowledge it is six month but my query is

1) Six month count from the date of clearance from factory ?

2) Six month count from the date of clearance from the custom port by custom authority ?

Regards

AI Summary

Proof of export deadline counted from factory clearance; ensure customs clearance within same period or seek AC/DC extension.
Submission of proof of export must be made within six months counted from the date of clearance from the factory; ensure customs port clearance occurs within the same six month period measured from factory clearance, and, if unavoidable circumstances arise, request a time extension from the AC/DC for submission of proof of export.
