Specific tariff entry prevails over residuary classification; duty demand survived, but bona fide dispute defeated penalty and confiscation.

Slag-wool and rock-wool were held classifiable under Heading 6803.00 because a specifically named tariff entry prevails over a broader or residuary description under Rule 3(a); Heading 6807.10 was rejected. The Tribunal also treated rock-wool in its pristine form as falling within Heading 6803, including where blast furnace slag was used in manufacture. On limitation, the open classification dispute and absence of an approved revised classification list kept the extended period available, so the duty demand was not time-barred. Penalty under Section 11AC and confiscation were set aside because the dispute was bona fide.

Issues: (i) Whether slag-wool and rock-wool manufactured by the assessee were classifiable under Heading 6803.00 or under Heading 6807.10 of the Central Excise Tariff. (ii) Whether the demand was barred by limitation and whether the penalty and confiscation were sustainable.

Issue (i): Whether slag-wool and rock-wool manufactured by the assessee were classifiable under Heading 6803.00 or under Heading 6807.10 of the Central Excise Tariff.

Analysis: The products were specifically named under Heading 6803.00. Rule 3(a) required preference to the heading giving the specific description over a more general or residuary description. Rule 3(c) was inapplicable because that rule operates only where competing headings equally merit consideration after initial classification uncertainty. The Tribunal also followed its earlier view that rock-wool in pristine form falls under Heading 6803 and not Heading 6807 merely because blast furnace slag was used in manufacture.

Conclusion: The goods were correctly classified under Heading 6803.00, and the assessee's classification claim under Heading 6807.10 failed.

Issue (ii): Whether the demand was barred by limitation and whether the penalty and confiscation were sustainable.

Analysis: For the relevant period, the assessee had no approved classification list after changing its claim, and the dispute on classification remained open. In that situation, the extended period was held to be available and limitation did not defeat the demand. However, the penalty under Section 11AC was found unwarranted because the controversy was treated as a bona fide classification dispute, and the confiscation and redemption fine were also not sustained for the same reason.

Conclusion: The demand was not barred by limitation, but the penalty and confiscation were set aside.

Final Conclusion: The classification and duty demand were upheld, while the penal consequences were deleted, resulting in only partial success for the assessee.

Ratio Decidendi: A product specifically described in a tariff heading must be classified under that specific heading, and the residuary or competing heading cannot be chosen unless the classification remains genuinely ambiguous; in an open classification dispute, limitation may not bar the demand, though bona fide dispute can justify deletion of penalty.
