Specific tariff entry prevails over general classification, and approved disclosure defeats extended limitation and penalty.

Micro porous rubber separators were held classifiable under Heading 8507.00 as separators for electric accumulators, not under Heading 4016.11, because a specific tariff description prevails over a general or exclusionary entry and HSN notes cannot override tariff wording. On limitation, the demand was barred where the classification had been disclosed through filed and approved classification lists and the department had earlier accepted the product after examination; suppression could not be inferred from a later change of view. As the extended period was unavailable, the demand failed and the associated penalty could not survive.

Issues: (i) Whether micro porous rubber separators were classifiable under Heading 8507.00 of the Central Excise Tariff Act, 1985 or under Heading 4016.11; (ii) Whether the demand was barred by limitation and, if so, whether penalty could survive.

Issue (i): Whether micro porous rubber separators were classifiable under Heading 8507.00 of the Central Excise Tariff Act, 1985 or under Heading 4016.11.

Analysis: Heading 8507.00 specifically covered electric accumulators including separators therefor. Heading 40.16 could operate only where the goods fell within that heading, and Section Note 1(a) to Section XVI could not be used to exclude an item specifically named elsewhere in the tariff. The goods were treated as vulcanised rubber sheets cut to size and not as articles taken out of Heading 40.08 by further working. Once they remained within Heading 40.08, they were not excluded from Section XVI and the specific description of separators under Heading 8507.00 prevailed over the general heading relied upon by the Department. The HSN notes could not override the tariff wording.

Conclusion: The separators were classifiable under Heading 8507.00 and not under Heading 4016.11, in favour of the assessee.

Issue (ii): Whether the demand was barred by limitation and, if so, whether penalty could survive.

Analysis: The assessee had manufactured the goods for years, classification lists had been filed and approved, and the Department had earlier accepted the classification even after examination of the product and its process. In such circumstances, the Department could not attribute suppression merely because it later changed its view. The extended period was therefore unavailable, and once the demand failed on limitation, the penalty based on the same demand could not stand.

Conclusion: The entire demand was time-barred and the penalty was unsustainable, in favour of the assessee.

Final Conclusion: The tariff entry specifically covering separators governed the classification, and the revenue's claim for duty was defeated by limitation, so the impugned order was set aside in full.

Ratio Decidendi: A goods description specifically provided in the tariff prevails over a general residuary or exclusionary entry, and the extended limitation period cannot be invoked where the classification was known to and approved by the Department without suppression by the assessee.
