Valuation under excise law requires rule-based reassessment where contract price is distorted by a special silver recovery arrangement.

Contractual valuation of batteries supplied with recovered silver could not be treated as normal price under section 4(1)(a) because the silver component was tied to a special recovery and purification arrangement, making the transaction price non-comparable with bullion-market silver. The proper approach was valuation under section 4(1)(b) and the Central Excise (Valuation) Rules, with the nearest ascertainable equivalent determined through the prescribed method and deductions. Bullion price could not be adopted mechanically without that rule-based exercise. The matter therefore required fresh reassessment under the valuation rules, rather than acceptance of the contract price as assessable value.

Issues: Whether the assessable value of batteries supplied to the Ministry of Defence, where silver recovered from old batteries was supplied as part of the arrangement, could be determined under section 4(1)(a) of the Central Excise Act, 1944, or whether recourse had to be taken to section 4(1)(b) and the Central Excise (Valuation) Rules, 1975.

Analysis: The contract price could not be treated as the normal price under section 4(1)(a) because the silver supplied for recovery was not comparable with bullion-market silver, and the transaction price was influenced by the special contractual arrangement for recovery and purification of silver. In such circumstances, the department was justified in moving away from section 4(1)(a) and proceeding under section 4(1)(b). At the same time, the department could not simply adopt bullion price without disclosing the prescribed method for arriving at the nearest ascertainable equivalent under the valuation rules. The proper course required examination of the relevant rules and necessary deductions, and the show cause notice and adjudication had not been worked out on that basis.

Conclusion: Section 4(1)(a) was not applicable on the facts, but the matter required fresh determination under section 4(1)(b) and the valuation rules. The issue is partly in favour of Revenue, with remand for reassessment.
