Input credit limitation: amendment restricts the period to claim credit and receipt of intermediate products under rule 57G. The Tenth Amendment substitutes the second proviso to rule 57G(2) to impose time limits: a manufacturer shall not take credit after six months from the date of issue of documents specified in the first proviso to sub rule (2); and where intermediate products made using inputs specified under the related inputs rule are received after nine months from that document date, the manufacturer shall not take credit.
