The Supreme Court has examined the scope of excise duty exemptions in cases involving mixed or indirect use of inputs, placing the spotlight on the interpretation of “intended use” versus actual use under exemption notifications.

The dispute arose from a long-standing excise duty demand raised by tax authorities on a fertilizer manufacturer that had procured Naphtha without payment of duty under exemption notifications. These notifications allowed duty-free procurement of inputs provided they were intended for use in the manufacture of fertilizers or ammonia.

However, the revenue contended that the input—Naphtha—was not used exclusively for fertilizer production. Instead, it was also utilized in generating steam and electricity, which in turn supported other operations such as chemical manufacturing and auxiliary industrial processes. 

Based on this, authorities issued multiple show cause notices spanning several years, alleging wrongful availment of exemption and demanding substantial excise duty along with interest and penalties. 

At the heart of the matter was a crucial legal question: should excise duty exemption depend strictly on the “intended use” of an input, or on its actual, exclusive end-use?

The taxpayer argued that the exemption notifications only required proof of intended use at the time of procurement. Since the input was primarily used to generate steam essential for fertilizer production, the condition was satisfied.

On the other hand, the tax department maintained that exemption should be denied proportionately to the extent the input was used for non-fertilizer purposes, even indirectly.

The Customs, Excise and Service Tax Appellate Tribunal (CESTAT) upheld the department’s approach, ruling that since Naphtha and natural gas were used together in a common system, it was not possible to segregate exact usage. Therefore, a proportionate method to determine non-eligible usage was reasonable. Duty could be demanded on the portion attributable to non-fertilizer activities. 

The tribunal also upheld penalties under the Central Excise Act, though it granted partial relief by setting aside certain rule-based penalties.

The Bombay High Court dismissed the appeal against a rectification order, holding that no substantial legal error existed.

The Supreme Court undertook a detailed examination of the statutory framework, exemption notifications, and procedural rules governing concessional duty.

A key focus of the Court was the meaning and scope of the phrase “intended use” in exemption notifications. The bench observed that exemptions tied to intended use are meant to facilitate specific industrial outcomes, such as fertilizer production. In complex industrial setups, inputs like fuel may serve multiple interconnected processes, making strict segregation impractical. 

The Court also evaluated whether the benefit of exemption could be denied merely because part of the output (like electricity) was used beyond the core manufacturing process.

Another major issue before the Court was whether the tax department was justified in invoking the extended limitation period of five years.

Under excise law, such extension is permitted only in cases involving fraud, suppression of facts, wilful misstatement, intent to evade duty

The Court emphasized that these conditions must be clearly established and cannot be presumed. Mere interpretational disputes or operational complexities would not automatically justify extended limitation or penalties.
