Manufacture by chemical addition, not mere dilution, determined duty liability and excluded retrospective Section 11AC penalty.

Tasopal-30 and Carewet (o) were treated as manufactured goods because ingredients beyond NP 100 were added in the laboratory, giving the products a distinct commercial identity and separate sale names; their clearances were therefore includible in the small-scale exemption limit and were dutiable. Tasopal-100, however, resulted only from adding an equal quantity of water to NP 100 and was held to be mere dilution, not manufacture. Section 11AC penalty was held inapplicable for the relevant period because it came into force only from 28-9-1996, leaving only any otherwise sustainable penalty under Rule 173Q. Quantification was remitted for fresh computation on that basis.

Issues: (i) Whether Tasopal-30 and Carewet (o) were manufactured products liable to duty and includible in the small-scale exemption limit, while Tasopal-100 was a product arising only from mere dilution; (ii) whether penalty could be imposed under Section 11AC of the Central Excise Act, 1944 for the relevant period.

Issue (i): Whether Tasopal-30 and Carewet (o) were manufactured products liable to duty and includible in the small-scale exemption limit, while Tasopal-100 was a product arising only from mere dilution.

Analysis: Tasopal-30 and Carewet (o) were found to contain ingredients beyond NP 100, with additional constituents added in the laboratory, and the resultant goods were sold under different names. They were therefore not products of mere dilution and had emerged through a process amounting to manufacture. By contrast, Tasopal-100 was produced by adding an equal quantity of water to NP 100, which was held to be mere dilution and not manufacture.

Conclusion: Tasopal-30 and Carewet (o) were held dutiable and their clearances were required to be included for computing the small-scale exemption limit, while Tasopal-100 was held not to be a manufactured product.

Issue (ii): Whether penalty could be imposed under Section 11AC of the Central Excise Act, 1944 for the relevant period.

Analysis: Section 11AC was held to be inapplicable to the period in question because it came into force only with effect from 28-9-1996. The matter was left open only to the extent that penalty, if otherwise sustainable, could be considered under Rule 173Q of the Central Excise Rules, 1944.

Conclusion: Penalty under Section 11AC was held not leviable for the relevant period.

Final Conclusion: The duty and penalty computation required reconsideration on the basis that only two products were dutiable, and the matter was sent back for fresh quantification and appropriate consequential action.

Ratio Decidendi: A product ceases to be a mere diluted form and amounts to manufacture where additional ingredients are added so that the resultant goods acquire a distinct commercial identity and are sold under a different name; penalty provisions cannot be applied retrospectively before their commencement.
