Manufacture by substantial processing and correct valuation method for free-supplied materials were the key issues in this excise dispute.

Crushing, pulverising, mixing with chemicals, moulding, curing and heat treatment of rejected refractory bricks was treated as manufacture because the resulting chemically bonded chrome manganese bricks were commercially distinct, with a different name, character and use. The appellant's reliance on repair or rectification authorities was held inapplicable. On valuation, duty had been worked out on a basis that excluded the value of free-supplied raw material, but the applicable valuation rule was not clearly identified and the correct hierarchy of valuation methods had not been properly applied. The valuation was therefore set aside and remanded for fresh determination under the correct provision with reasons.

Issues: (i) Whether the process of crushing, pulverising, mixing with chemicals, moulding, curing and heat treatment of broken refractory bricks resulted in manufacture of a new excisable product. (ii) Whether the assessable value could be determined by including the cost of free-supplied broken bricks and whether the valuation required reconsideration under the correct valuation rules.

Issue (i): Whether the process of crushing, pulverising, mixing with chemicals, moulding, curing and heat treatment of broken refractory bricks resulted in manufacture of a new excisable product.

Analysis: The input material consisted of old and rejected refractory bricks and brick-bats. These were subjected to crushing, pulverising, screening, grading, mixing with binding chemicals and water, moulding, curing and heat treatment. The resulting goods were commercially different from the input material and were known as chemically bonded chrome manganese bricks. The resulting product had a different name, character and use. The authorities relied upon by the appellant were found to concern repair or rectification situations and were held inapplicable.

Conclusion: The process amounted to manufacture and the appellant's contention on this issue was rejected.

Issue (ii): Whether the assessable value could be determined by including the cost of free-supplied broken bricks and whether the valuation required reconsideration under the correct valuation rules.

Analysis: The duty had been paid on a value which excluded the cost of the raw material supplied free by the buyer, so the transaction was not at arm's length. While the department sought to add a cost figure based on one purchase transaction, the order did not clearly identify the exact provision of the valuation rules applied. The valuation appeared to have been made under the costing method, but that could not be done without first excluding the preceding methods under the valuation rules. The matter therefore required fresh determination by the original authority under the correct legal provision with reasons.

Conclusion: The valuation orders were set aside and the issue was remanded for de novo consideration.

Final Conclusion: The appellant failed on the manufacture question, but succeeded in obtaining a remand on valuation, so the dispute was only partly resolved in its favour.

Ratio Decidendi: Where rejected input material is transformed through substantial processing into a commercially distinct product with a different name, character and use, manufacture is established; and where valuation is based on non-arm's-length supplies, it must be determined under the correct statutory valuation method by a reasoned fresh assessment.
