Compost manure exemption under central excise turns on natural fermentation, no power use, and specific tariff notification coverage.

Compost manure produced from garbage by natural fermentation without the aid of power was treated as exempt from central excise duty. The Gujarat HC noted that the product fell within Notification No. 179/77 for goods manufactured without power, and was later specifically exempted by Notification No. 181/80-C.E. The Court further observed that, before the explanation was added to Tariff Item 68, goods specifically excluded from Tariff Item 14HH could not be shifted into the residuary entry. On those facts, compost manure was not exigible to duty and the direction requiring licence and duty payment was unsustainable.

Issues: Whether compost manure produced from garbage by a natural fermentation process, without the aid of power, was liable to central excise duty under the residuary tariff item, or was exempt/not covered because of the specific tariff exclusion and exemption notifications.

Analysis: The process described showed that garbage was subjected to segregation and natural fermentation in open-air conditions for several weeks, and there was no rebuttal to the assertion that no power was used. On those facts, the product fell within the exemption for goods manufactured without the aid of power under Notification No. 179/77. In addition, compost manure was expressly inserted as an exempt item by Notification No. 181/80-C.E. dated 12 November 1980. The Court also held that, prior to the addition of the explanation to Tariff Item 68, a product specifically excluded from Tariff Item 14HH could not be forced into the residuary item. After the explanatory amendment, the residuary item could extend to such excluded goods, but that issue did not affect the present case because the later exemption notification governed compost manure.

Conclusion: Compost manure was not exigible to duty on the facts of the case and the impugned direction requiring licence and duty payment was unsustainable.

Ratio Decidendi: Where a product is produced by a natural process without the aid of power and is covered by a specific exemption notification, excise duty cannot be demanded by classifying it under the residuary tariff item.
