Classification of Activated Bleaching Earth from fullers earthcourt affirms mechanical and chemical processing transforms raw material into excisable product.

Mechanical crushing, chemical treatment, heating and pulverising of fullers earth that enhance bleaching ability and filtration rate constitute an alteration of the raw materials nature, amounting to manufacture; the processed product qualifies as activated bleaching earth tailored to client specifications and is distinct in use from untreated fullers earth, with adverse factual challenges rejected and the impugned appeal dismissed. The reasoning rests on findings that the combined mechanical and chemical processes produce a commercially different product with enhanced properties and performance, satisfying the test for transformation into an excisable product.

Issues Involved:
1. Whether the process undertaken by the appellant amounts to manufacture.
2. Classification of the products under the Central Excise Tariff Act.
3. Identification of the raw material in question.
4. Justification for invoking the extended period of limitation under Section 11A.
5. Justification for clubbing all years together for duty calculation.

Summary:

Issue 1: Whether the process undertaken by the appellant amounts to manufacture.
The court examined the definition of "manufacture" under Section 2(f) of the Central Excise Act, 1944. The process involved crushing fuller's earth lumps, heating the powder, and treating it with chemicals to produce activated bleaching earth. The court referred to the Supreme Court's tests to determine manufacture: whether a different product comes into existence and whether the original product ceases to exist. It was concluded that the process altered the characteristics of fuller's earth, creating a new product with different uses, thus amounting to manufacture.

Issue 2: Classification of the products under the Central Excise Tariff Act.
The court affirmed that the resultant product, activated bleaching earth, should be classified under Chapter Heading 3802 of the Central Excise Tariff Act. The process undertaken by the appellant, including chemical treatment and heating, transformed fuller's earth into a product with enhanced bleaching and filtration properties, fitting the classification criteria.

Issue 3: Identification of the raw material in question.
The appellant contended that fuller's earth is different from bentonite or motmorillanite, as supported by expert opinions. However, the court found that the process undertaken by the appellant, including chemical and thermal treatment, transformed fuller's earth into activated bleaching earth, aligning with the findings of the authorities.

Issue 4: Justification for invoking the extended period of limitation under Section 11A.
The court upheld the invocation of the extended period of limitation, noting that the appellant had contravened Central Excise Rules with the intent to evade duty. The appellant's records and invoices described the product as activated bleaching earth, supporting the authorities' findings of suppression of facts.

Issue 5: Justification for clubbing all years together for duty calculation.
The court did not find merit in the appellant's argument against clubbing all years together for duty calculation. The authorities' approach was justified given the continuous nature of the appellant's manufacturing process and the consistent classification of the product.

Conclusion:
The court rejected the appeal, affirming the orders of the lower authorities and the Tribunal. The process undertaken by the appellant was deemed to amount to manufacture, the product was correctly classified, and the extended period of limitation was justifiably invoked. The appeal was devoid of merit and dismissed without costs.
