Assessable value excludes customer-supplied denaturants when commercial valuation shows no extra consideration or flow back.

Customer-supplied denaturants were held not to be separately includible in the assessable value of Special Denatured Spirit under Section 4 valuation principles, because the goods were sold at the factory gate on commercial terms and there was no evidence of extra-commercial consideration or flow back. The department also failed to show that the cost of the free-supplied denaturants had been omitted from the invoice-based valuation. The Tribunal further accepted that Special Denatured Spirit could not be valued merely by comparison with Ordinary Denatured Spirit, and upheld the appellate reasoning on the facts found.

Issues: Whether the value of denaturants supplied free of cost by customers was required to be included in the assessable value of Special Denatured Spirit for central excise purposes.

Analysis: The dispute turned on Section 4 of the Central Excise Act, 1944 and the Central Excise (Valuation) Rules, 2002. The appellate authority found that the assessee sold the goods at the factory gate on commercial terms, that there was no evidence of any extra-commercial consideration or flow back, and that the department had not shown that the cost of the customer-supplied denaturants had been omitted from the invoice-based valuation. It further held that the product mix and pricing of Special Denatured Spirit could not be benchmarked merely against Ordinary Denatured Spirit for valuation purposes. The Tribunal found no infirmity in that reasoning.

Conclusion: The value of the customer-supplied denaturants was not liable to be separately added to the assessable value on the facts found, and the revenue's challenge failed.

Ratio Decidendi: Where the department fails to displace a finding that customer-supplied inputs were already reflected in the commercial valuation and no extra-commercial consideration or flow back is shown, such inputs are not independently includible in assessable value under Section 4 valuation principles.
