Excisability of coal waste turns on marketability and commercial identity; extended limitation needs suppression or intent to evade duty.

Coal char, coal dust and coal shell arising during manufacture were treated as spent coal with reduced calorific value, but they were not held dutiable merely because they fetched a price or appeared in the tariff. The analysis states that marketability alone does not establish excisability unless the material has commercial identity as the goods claimed under the relevant heading; on that basis, the demand failed on merits. On limitation, the extended period was found unavailable because the record showed disclosure in returns and declarations, departmental awareness, and no suppression or intent to evade duty. The article concludes that the demand was unsustainable on both classification and limitation.

Issues: (i) Whether coal char, coal dust and coal shell arising in manufacture were dutiable as excisable waste under the tariff. (ii) Whether the extended period of limitation was invocable.

Issue (i): Whether coal char, coal dust and coal shell arising in manufacture were dutiable as excisable waste under the tariff.

Analysis: The items were treated as spent coal with reduced calorific value. There was no evidence of trade parlance showing that such waste was regarded as coal merely because it fetched a price. Marketability by itself did not establish excisability, and the material did not generate heat or answer classification as coal under the relevant tariff heading.

Conclusion: The items were not dutiable as excisable goods and the demand on classification failed in favour of the assessee.

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

Analysis: The original authority had recorded absence of suppression and noted that the department was aware of the facts and that declarations had been filed. The record also showed disclosure of the item in returns and other declarations, negating any intention to evade duty.

Conclusion: The extended period of limitation was not invocable and the limitation objection succeeded in favour of the assessee.

Final Conclusion: The demand was unsustainable both on merits and on limitation, and the appeal succeeded.

Ratio Decidendi: A product or waste is not excisable merely because it is mentioned in the tariff or fetches a price; excisability depends on marketability and commercial identity, and the extended limitation period requires suppression or intent to evade duty.
