Functional test for mining inputs under Central Sales Tax: diesel qualifies, cement needs limited reconsideration, penalty notice left open.

Goods used in an integrated mining operation may qualify for concessional purchase under the Central Sales Tax regime even if they do not enter the final product, where they are functionally and commercially necessary to the process. High speed diesel was treated as directly consumed in running mining machinery and therefore covered by the statutory facility. Cement was also treated as eligible, but only to the extent it was used for installation and essential mining infrastructure, requiring reconsideration of its period and extent of use. The penalty notice under section 10A was not finally determined, and the dealer was left to reply before the assessing authority.

Issues: (i) Whether high speed diesel and cement were goods intended for use in mining or in the manufacture or processing of goods for sale so as to qualify for inclusion in the registration certificate and concessional purchase under the Central Sales Tax regime. (ii) Whether the deletion of cement and high speed diesel from the registration certificate was legally sustainable. (iii) Whether the penalty proceeding initiated under section 10A of the Central Sales Tax Act required interference at this stage.

Issue (i): Whether high speed diesel and cement were goods intended for use in mining or in the manufacture or processing of goods for sale so as to qualify for inclusion in the registration certificate and concessional purchase under the Central Sales Tax regime.

Analysis: Section 8(3)(b) of the Central Sales Tax Act, 1956, read with Rule 13 of the Central Sales Tax (Registration and Turnover) Rules, 1957, permits purchase of goods intended for use as raw materials, processing materials, machinery, plant, equipment, tools, stores, spare parts, accessories, fuel or lubricants in mining or in manufacture or processing of goods for sale. The functional test applies: if a process is integrally connected with the mining operation and commercial production would be inexpedient without it, the goods used in that process fall within the statutory description. High speed diesel was found to be directly consumed in running mining machinery and thus integral to mining and processing of ore. Cement was found to be required for installation of machinery and construction of benches and plates used in the mining operation, though its use was mainly at the initial stage.

Conclusion: High speed diesel qualified for inclusion and concessional purchase in relation to the mining operation; cement also qualified, but only to the extent of its use in the mining project and for the period during which such use was necessary.

Issue (ii): Whether the deletion of cement and high speed diesel from the registration certificate was legally sustainable.

Analysis: The impugned deletion proceeded on the premise that neither item was directly used in manufacture or processing. That approach was too restrictive because the statutory scheme does not confine eligible goods to those physically entering the end product. Goods used in an integrated mining and processing operation may qualify if they are commercially necessary and functionally connected with the process. On that test, deletion of high speed diesel could not stand. As regards cement, the record showed that its role was confined substantially to installation and initial infrastructure for mining machinery, so a blanket inclusion was not justified without determining the period and extent of allowable use.

Conclusion: The deletion order was unsustainable in respect of high speed diesel and required reconsideration in respect of cement.

Issue (iii): Whether the penalty proceeding initiated under section 10A of the Central Sales Tax Act required interference at this stage.

Analysis: The notice initiating penalty was challenged as premature and without basis, but the matter was not finally adjudicated on merits. The petitioner was left free to submit a reply before the assessing authority, which was directed to decide the matter in the light of the judgment.

Conclusion: No final finding was recorded on the penalty proceeding, and the petitioner was relegated to reply before the authority.

Final Conclusion: The writ petition succeeded in part. The orders deleting the disputed items were set aside, high speed diesel was treated as covered by the statutory mining purchase facility, cement was remitted for limited reconsideration on the extent and period of admissible use, and the penalty matter was left for fresh decision by the authority.

Ratio Decidendi: Under section 8(3)(b) of the Central Sales Tax Act, 1956, read with Rule 13, goods need not enter the final product to qualify; if they are functionally and integrally connected with mining or manufacturing and commercially necessary for the process, they fall within the statutory description of goods intended for use in that process.
