Manganese ore processing and extended limitation depend on technical proof of manufacture and absence of suppression

Processes on manganese ore such as heating, quenching, drying and pulverising amount to manufacture only if proper technical material shows that they create a new commercially and technically distinct product and take the goods outside Chapter 26; absent that proof, classification requires fresh factual examination. The extended period of limitation is unavailable where the assessee had disclosed the essential process and the department had earlier clarified the classification and exemption position, because suppression or misstatement is not established on the record.

Issues: (i) Whether the processes undertaken on manganese ore resulted in manufacture and took the product out of Chapter 26 of the Central Excise Tariff Act, 1985; (ii) Whether the extended period of limitation was invocable.

Issue (i): Whether the processes undertaken on manganese ore resulted in manufacture and took the product out of Chapter 26 of the Central Excise Tariff Act, 1985.

Analysis: The applicable chapter notes and HSN guidance permit certain physical, physico-chemical and chemical operations normal to preparation of ores, including crushing, grinding, drying, calcination and roasting to oxidise, reduce or magnetise the ore, but exclude processes not normal to the metallurgical industry or those that alter the basic ore in a manner taking it outside the chapter. On the material before it, the record did not conclusively establish, on technical evidence, that the appellant's process of heating, quenching with water, drying and pulverising created a new commercially and technically distinct product so as to amount to manufacture and exclude the goods from Chapter 26.

Conclusion: The matter on manufacture and classification required fresh examination by the adjudicating authority, with technical evidence if necessary, and the issue was not finally decided in favour of the Revenue.

Issue (ii): Whether the extended period of limitation was invocable.

Analysis: The appellant had disclosed the essential process to the department in earlier correspondence, and the department had itself clarified the classification and exemption position. In these circumstances, the allegation of suppression or misstatement to justify the extended period was not sustainable on the record.

Conclusion: The extended period of limitation was held not invocable; the demand, if any, was confined to the normal period.

Final Conclusion: The appeal was allowed by remand for reconsideration of the manufacture and classification issue, while the limitation objection succeeded to the extent that the extended period could not be applied.

Ratio Decidendi: A process on ore will not be treated as manufacture unless the department establishes, on proper technical material, that it takes the goods outside the relevant chapter and creates a new commercially distinct product; extended limitation cannot be invoked absent proved suppression or misstatement.
