Commercial contract pricing governs excise valuation where no extra-commercial consideration or flow back is shown; penalty cannot survive.

Contract prices supported by commercial considerations could not be rejected for excise valuation merely because different prices were charged to different buyers or the same class of buyers. The text states that where purchase orders and market factors such as quantity or delivery terms justify differentiated pricing, and there is no evidence of extra-commercial consideration, flow back, or suppression, the assessable value of Sodium Sulphate could not be enhanced. On the same basis, the Rule 173Q penalty was unsustainable because the valuation demand itself failed and no independent basis for evasion was shown.

Issues: (i) Whether the assessable value of Sodium Sulphate could be enhanced by disregarding the contract price recorded in the purchase orders and by treating the sale price of Rs. 675 per MT as not reflecting the correct normal price. (ii) Whether the penalty imposed under Rule 173Q was sustainable.

Issue (i): Whether the assessable value of Sodium Sulphate could be enhanced by disregarding the contract price recorded in the purchase orders and by treating the sale price of Rs. 675 per MT as not reflecting the correct normal price.

Analysis: Different prices to different buyers, and even to the same class of buyers, are permissible where they are supported by commercial considerations. The departmental instructions recognize that different prices may be fixed depending on quantity, delivery period, or other normal commercial factors, and contract sales supported by purchase orders cannot be rejected merely because a lower price was charged. The record did not show any material to infer that the disputed supplies were not made at arm's length or that there was any extra-commercial consideration or flow back. Earlier approvals of similar differentiated prices for other buyers also indicated that such contractual pricing was known and accepted.

Conclusion: The contract price could not be rejected and no enhancement of assessable value was justified.

Issue (ii): Whether the penalty imposed under Rule 173Q was sustainable.

Analysis: Once the contract price was accepted as the proper basis for valuation and no suppression or other improper consideration was established, there remained no foundation for alleging evasion of duty. In the absence of a valid demand on valuation, the penalty could not survive.

Conclusion: The penalty was not sustainable and was liable to be set aside.

Final Conclusion: The valuation adopted by the appellants was accepted as contractual and commercially justified, the duty demand failed, and the connected penalty also failed.

Ratio Decidendi: Where sales are effected under genuine contract prices supported by commercial considerations and there is no evidence of extra-commercial consideration, suppression, or flow back, the assessable value under excise law cannot be enhanced merely because different prices are charged, and consequential penalty cannot be sustained.
