Notional interest on customer advances is taxable only if advances and related terms depress the sale price under excise valuation rules.

Notional interest on customer advances is not includible in excisable value as a matter of rule. Under Section 4, the normal price must be the sole consideration, and Rule 5 applies only where the department shows that an advance or related commercial arrangement constitutes additional consideration with a nexus to and depressive effect on the sale price. The factual enquiry must consider the contractual price structure and the effect of the bank guarantee. Because that enquiry had not been properly examined, the matter required fresh consideration on whether the advances and guarantee reduced the price and attracted Rule 5.

Issues: Whether notional interest on advance payments, together with the effect of the bank guarantee furnished by the manufacturer, was includible in the assessable value of the transformers under the excise valuation provisions.

Analysis: Under Section 4, the relevant test is the normal price at which goods are ordinarily sold in wholesale trade, and the price must be the sole consideration for the sale. Rule 5 applies only when the price is not the sole consideration and some additional consideration flows directly or indirectly from the buyer to the assessee. Advance payments by themselves do not automatically amount to additional consideration. The decisive question is whether the advances and the accompanying commercial terms had a nexus with the sale price and depressed it. The lower authorities had not examined that question on the facts, especially in light of the bank guarantee and the contractual price structure.

Conclusion: Notional interest could not be added as a matter of rule, and the matter had to be examined afresh to determine whether the advances and bank guarantee depressed the sale price and thereby attracted Rule 5.

Ratio Decidendi: Notional interest on customer advances is includible in excisable value only when the department establishes, on the facts of the case, that the advance or related commercial arrangement constitutes additional consideration having a nexus with and depressing the sale price.
