Excise valuation of waste by-product cannot include processor's separate sale proceeds when the cleared material is not excisable goods.

Waste pickle liquor, arising as a waste product in the pickling process, was not a manufactured and independently marketable excisable good, so Rule 6 of the Excise Valuation Rules, 2000 could not be applied to its valuation. Credit notes received from the processor against the processor's separate sale of ferric oxide were not additional consideration flowing from the buyer to the assessee for the waste liquor cleared. As the proceeds related to a distinct post-clearance transaction and did not alter the character or assessability of the waste as cleared, the credit notes were not includible in the transaction value and no duty demand could be sustained on that basis.

Issues: Whether the credit notes received from the processor against sale of ferric oxide generated out of waste pickle liquor were liable to be included in the assessable value of waste pickle liquor under Rule 6 of the Excise Valuation Rules, 2000.

Analysis: Waste pickle liquor emerged as a waste product during the pickling process and was not a manufactured product with independent marketability. Rule 6 applies only where the goods are excisable goods and the price is not the sole consideration. Since waste pickle liquor was held not to be excisable goods, the valuation rules could not be invoked to treat the credit notes, being part of the processor's sale proceeds from ferric oxide, as additional consideration flowing from the buyer to the assessee. The receipt of such proceeds did not alter the character or assessability of the waste in the form in which it was cleared.

Conclusion: The credit notes were not includible in the transaction value of waste pickle liquor and no duty demand could be sustained on that basis.

Ratio Decidendi: Valuation under Rule 6 of the Excise Valuation Rules, 2000 can be applied only to excisable goods, and proceeds arising from a processor's separate sale of a by-product generated after clearance of waste do not constitute additional consideration for the waste cleared by the assessee.
