A. The notf. No. 32/94-ce non tariff allowed the credit on the basis of invoices issued by the importer.
B. With the amendments vide notf. 5/95 the importers were required for regn.
C. In the new rule 9 of CE though the specific mention was not there for importers, they were like any other traders to take regn as dealers.
D. Moreover at the relevant time the invoice issued by the importers was relevant document for taking credit under rule 9 of CCR.
E. It emerges that the specific requirement of regn was not there to take regn even if they can issue invoices.
F. A draft circular was circulated inviting comments in this regard to mitigate such problems
F. Perhaps due to the noon requirement of regn., the circular was not issued
