Excise valuation and exemption principles: captive clearances used bulk buyer price, barred retrospective demand, and preserved substantive exemption.

For excise valuation of captively consumed calcined alumina, negligible and sporadic sales to casual buyers were not treated as representative of normal wholesale trade, and the comparable price charged to a similarly situated bulk industrial buyer was adopted as the assessable value. An approved price list could not be reopened retrospectively in the absence of any challenge to the approval, so no short-levy demand was sustainable on that basis. Exemption under Notification No. 217/86 remained available where the goods were used within the same manufacturer's unit for further manufacture, and procedural non-compliance with Chapter X did not defeat the substantive benefit once in-house use was established.

Issues: (i) whether the price charged to M/s. BALCO or the sporadic factory-gate sales to casual buyers should be adopted for valuation of calcined alumina transferred to the sister unit; (ii) whether duty could be demanded retrospectively in respect of approved Price List No. 2/87; and (iii) whether exemption under Notification No. 217/86 was available despite non-compliance with Chapter X procedure for the relevant period.

Issue (i): whether the price charged to M/s. BALCO or the sporadic factory-gate sales to casual buyers should be adopted for valuation of calcined alumina transferred to the sister unit.

Analysis: The sales to casual buyers were negligible, occasional and not shown to be representative of ordinary wholesale trade. Buyers purchasing such small quantities formed a different class from bulk industrial consumers. The price charged to M/s. BALCO, which was similarly situated as a manufacturer using alumina for aluminium production, was the appropriate comparable price for the captively consumed goods.

Conclusion: The price charged to M/s. BALCO was to be adopted as the assessable value for the transferred calcined alumina.

Issue (ii): whether duty could be demanded retrospectively in respect of approved Price List No. 2/87.

Analysis: The price list had been approved by a speaking order and no appeal had been filed against that approval. In the absence of a valid basis to reopen the approved valuation retrospectively, and applying the principle that no short-levy arises when duty is paid on the basis of an approved classification or price list, the proposed retrospective demand was unsustainable.

Conclusion: No duty demand could be raised retrospectively in respect of Price List No. 2/87.

Issue (iii): whether exemption under Notification No. 217/86 was available despite non-compliance with Chapter X procedure for the relevant period.

Analysis: There was no dispute that the calcined alumina was used within the same manufacturer's unit for manufacture of aluminium. The exemption was therefore substantively available, and failure to follow the procedure could not defeat the benefit where the intended use was established and the procedural non-compliance was attributable to the revenue-related dispute over credit availability.

Conclusion: The assessee was entitled to the benefit of Notification No. 217/86 for the relevant period despite non-compliance with Chapter X procedure.

Final Conclusion: The valuation of captively consumed alumina was linked to the comparable price charged to the similarly situated bulk buyer, the retrospective demand on the approved price list was disallowed, and the exemption for in-house use was upheld for the specified period.

Ratio Decidendi: For excise valuation, negligible and sporadic sales to a different class of buyers do not constitute the normal assessable price for captive clearances, and substantive exemption cannot be denied merely for procedural non-compliance where the intended in-factory use is established.
