Hi all we have major purchase from Import and while importing we have paid Import duty along with IGST. But for maximum imports IGST had not been appearing in our GSTR 2A.
As per entry details u paid igst,While entry in ward detail of impot in table ,which will b considered as blocked ITC.Then supply by u ,may collect igst or CGST/SGST as per ur invoice with output amount from ur customer with in the prescribed time .
I have been facing the same issue. You can use the self service functionality called "BOE Search" in your portal to fetch BOE from ICEGATE. It can help you to some extent.
Take ITC on the basis of bill of entry. There wont be problem in cases of import itc if not getting reflected in GSTR-2B. Also raise a complaint ticket for the same.
