Functional tariff classification denied for ammonium nitrate melt; fertilizer-related exemptions, extended limitation, and penalty were upheld.

Ammonium nitrate (melt) produced for captive consumption was not a fertilizer because it was never used or intended to be used as such; it was consumed in manufacture of ammonium nitrate (prilled), and was correctly classified under Item 68. Because the inputs were used to produce a non-fertilizer product, exemption under the relevant notifications for fertilizer manufacture was unavailable. The extended limitation period was justified by failure to maintain proper records and continued reliance on an unsustainable exemption claim after departmental clarification, and the penalty was upheld as commensurate with the evasion and conduct.

Issues: (i) whether ammonium nitrate (melt) produced for captive consumption was a fertilizer classifiable under Tariff Item 14-HH; (ii) whether low sulphur heavy petroleum stock and ammonia used in its manufacture were entitled to exemption under the relevant notifications; and (iii) whether the demand was barred by limitation and the penalty was sustainable.

Issue (i): whether ammonium nitrate (melt) produced for captive consumption was a fertilizer classifiable under Tariff Item 14-HH.

Analysis: The product was not used or intended to be used as fertilizer, but was consumed entirely in a continuous process for manufacture of ammonium nitrate (prilled), which was treated as explosive. Ammonium nitrate has different grades, and the fertilizer grade is distinct from the explosive grade. Where the tariff description is functional and turns on use as fertilizer, end use becomes relevant. A product that is never used as fertilizer cannot be brought within the expression "fertilizers, all sorts".

Conclusion: The product was not a fertilizer and was correctly held classifiable under Item 68, against the assessee.

Issue (ii): whether low sulphur heavy petroleum stock and ammonia used in its manufacture were entitled to exemption under the relevant notifications.

Analysis: The notifications granted relief only where the inputs were used in the manufacture of fertilizer. Since ammonium nitrate (melt) was not a fertilizer, the inputs used for its production did not satisfy the condition of use in fertilizer manufacture. The later deletion of ammonium nitrate from the exemption notification and the trade notice issued by the Department were consistent with the product's non-fertilizer character.

Conclusion: The exemption was not admissible, against the assessee.

Issue (iii): whether the demand was barred by limitation and the penalty was sustainable.

Analysis: The assessee failed to maintain proper records despite repeated departmental instructions and persisted in taking an unsustainable exemption position after the trade notice and amended notification. These facts amounted to wilful suppression for evasion of duty, justifying the extended period. The amount of penalty was also considered commensurate with the duty evaded and the manner of conduct.

Conclusion: The extended limitation period applied and the penalty was upheld, against the assessee.

Final Conclusion: The classification, denial of exemption, invocation of the extended limitation period, and penalty were all sustained, leaving the impugned order intact.

Ratio Decidendi: Where a tariff entry is functional and depends on use as fertilizer, a product not used or intended to be used as fertilizer cannot claim fertilizer classification or related input exemptions; deliberate non-maintenance of records and suppression of material facts justifies the extended period for demand.
