Dear Rajeev,
The provisions of Rule 4 ( sub rule 1 to 5 ) of the Removal of goods (under concessional rate of duty) Rules,2016 specifies that....
a. The manufacturer intended to procure goods should number the intimation under sub-rule (1) Financial year wise
b. should execute a general Bond with surety.
The above provision does not specify any thing about execution of Bond Financial year wise except the financial year wise numbering on the intimation.
In view of this , you may highlight this to your excise authorities and try to convince them.
However, the duty involved in the goods proposed to be procured in the next financial year exceeds the value of the Bond already executed, you may have to execute either an additional Bond for the differential amount or to execute a fresh Bond cancelling the existing Bond. You may please check this aspect also.
Best Regards
Suryanarayana
