Assessable value under excise law excludes notional interest and refundable die security absent proof of price suppression.

Notional interest on buyer advances is includible in assessable value only where the Revenue proves a real nexus between the advance and a depressed sale price; on the facts, no consistent price suppression was shown, so the interest was excluded. Die security collected for customised goods, being refundable and intended to secure performance, was not an additional element of price and was also excluded from assessable value. The commentary states that valuation demands and penalties could not be sustained on these grounds. The stated ratio is that an advance or security amount enters assessable value only when it operates as additional consideration or actually depresses the sale price.

Issues: (i) Whether notional interest on advances received from a buyer was includible in the assessable value under section 4 of the Central Excise Act. (ii) Whether die security collected from buyers was includible in the assessable value of the goods.

Issue (i): Whether notional interest on advances received from a buyer was includible in the assessable value under section 4 of the Central Excise Act.

Analysis: Inclusion of notional interest on advances is permissible only where a nexus is shown between the advance and the sale price and the advance has the effect of depressing the price charged to the buyer. The material on record did not establish that the prices charged to the concerned buyer were consistently lower because of the advance. The comparative instances relied upon by the Revenue were insufficient, while the sale chart produced by the assessee showed that in most cases there was no meaningful price difference and any variation was marginal.

Conclusion: The notional interest on the advances was not includible in the assessable value, in favour of the assessee.

Issue (ii): Whether die security collected from buyers was includible in the assessable value of the goods.

Analysis: Die security collected in relation to customised goods was intended to secure performance and was refundable on purchase of the requisite quantity of goods. The fact that refunds had been made in some cases supported the assessee's explanation. On these facts, the amount could not be treated as an additional element of price forming part of the assessable value.

Conclusion: The die security was not includible in the assessable value, in favour of the assessee.

Final Conclusion: The demand and penalty could not be sustained on valuation grounds, and the appeal succeeded.

Ratio Decidendi: An advance or security amount is includible in the assessable value only when the Revenue proves a real nexus with the price and shows that it operated as an additional consideration or depressed the sale price.
