Proving invoice deductions for exemption and defeating limitation pleas require reliable evidence and the correct statutory notice basis.

Deductibility of freight, packing, discounts, commission, banking charges and export-clearance items for exemption under Notification No. 176/77 depended on reliable proof, and the claimed deductions were disallowed because the invoices and accounts did not satisfactorily establish the components or show that trade discounts were uniformly available to the trade. The limitation plea also failed because the notice proceeded on removal of excisable goods without payment of duty and operation without a licence, not on short levy under the relevant short-levy provisions. The duty demand was therefore upheld and no relief was granted.

Issues: (i) Whether deductions claimed from the invoice value, including freight, packing, trade discount, turnover bonus, cash discount, commission, banking charges and export clearances, were admissible for determining eligibility to exemption under Notification No. 176/77; (ii) Whether the demand was barred by limitation.

Issue (i): Whether deductions claimed from the invoice value, including freight, packing, trade discount, turnover bonus, cash discount, commission, banking charges and export clearances, were admissible for determining eligibility to exemption under Notification No. 176/77.

Analysis: The claimed deductions were not supported by satisfactory evidence. The invoices did not disclose the discounts or deductions, the sale accounts did not establish freight or insurance components, and the record did not satisfactorily show that the discounts were uniformly available to the trade. The Tribunal treated uniform availability as material for allowing trade discounts, and found the evidence regarding quantity discount, commission and secondary packing insufficient. The challenge relating to export clearances was raised for the first time in second appeal and was not necessary for decision in view of the failure of the other deductions.

Conclusion: The deductions were rightly disallowed and the assessee's challenge on exemption eligibility failed.

Issue (ii): Whether the demand was barred by limitation.

Analysis: The show cause notice was issued for removal of excisable goods without payment of duty under Rule 9(2) and for operating without a licence, and was not a notice for short levy under Rule 173-J read with Rule 10. On the facts, the limitation plea based on short levy did not apply.

Conclusion: The demand was not barred by limitation.

Final Conclusion: The Tribunal upheld the duty demand and declined to interfere with the order under challenge, leaving the assessee without relief.

Ratio Decidendi: Deductions from invoice value for exemption purposes must be proved by reliable evidence and, where trade discount is relied upon, it must be shown to be available to the trade in the relevant sense; a limitation plea based on short levy fails where the notice proceeds on removal without payment of duty.
