Commercial parlance governs tariff classification of agricultural zinc sulphate; time-barred demand cannot sustain duty liability.

Agricultural grade zinc sulphate is discussed as a tariff classification issue where the undefined term "fertilizers" was construed in commercial and technical parlance. Contemporary materials such as Indian Standards, the Fertilizer Control Order, ISI marking and market usage supported treatment of the product as a fertilizer-bearing micronutrient, so it fell under Item 14-HH and not Item 68. The article also notes that, because there was no suppression of facts and the later notice operated beyond the statutory period, the extended limitation period was unavailable and the duty demand could not be sustained.

Issues: (i) Whether agricultural grade zinc sulphate is classifiable as a fertilizer under Item 14-HH of the Central Excise Tariff Schedule or as a micronutrient under Item 68; (ii) Whether the demand was barred by limitation and no duty could be fastened on the assessee.

Issue (i): Whether agricultural grade zinc sulphate is classifiable as a fertilizer under Item 14-HH of the Central Excise Tariff Schedule or as a micronutrient under Item 68.

Analysis: Item 14-HH used the wide expression "fertilizers, all sorts" without defining fertilizer. The product was understood in commerce, industry and technical material as a fertilizer-bearing micronutrient. The Indian Standards glossary, the Fertilizer Control Order, Schedule I thereto, the product's ISI marking and the manner in which it was marketed supported its treatment as fertilizer. The prior exemption notification covering micronutrients also showed contemporaneous governmental understanding that micronutrients fell within the fertilizer entry. The cited technical texts and high court decisions did not dislodge that understanding.

Conclusion: Agricultural grade zinc sulphate is classifiable under Item 14-HH of the Central Excise Tariff Schedule and not under Item 68.

Issue (ii): Whether the demand was barred by limitation and no duty could be fastened on the assessee.

Analysis: The department accepted that there was no suppression of material facts. The later notice, styled as a corrigendum, operated as an independent show cause notice and was issued beyond the statutory period for the period in dispute. The extended period was therefore unavailable, and the classification adopted by the Collector outside the scope of the notice could not sustain the demand.

Conclusion: The demand was barred by limitation and no duty liability could be fastened on the assessee.

Final Conclusion: The classification made by the Collector was set aside, the appeal succeeded, and the assessee obtained consequential relief.

Ratio Decidendi: In tariff classification, an undefined expression must be construed in commercial and trade parlance, and where contemporaneous statutory and administrative materials consistently treat a product as falling within the tariff description, that understanding governs unless clearly excluded; a time-barred show cause notice cannot sustain a duty demand.
