Engine parts classification and extended limitation sustained, while penalty and interest were limited to the period after 28-9-1996.

Goods cleared for use in internal combustion engines were held classifiable under Heading 84.09 as parts specifically suitable for engines, not under Heading 84.32 as parts of power tillers. The non-disclosure of their true use in classification declarations amounted to suppression of material facts, so the extended period of limitation was correctly invoked and the demand was not time-barred. Penalty under Section 11AC and interest under Section 11AB, however, could not be applied to the period before 28-9-1996 because those provisions operated prospectively; liability for penalty and interest was therefore required to be re-determined for the later period only.

Issues: (i) Whether the disputed goods were classifiable as parts of internal combustion engines under Heading 84.09 or as parts of power tillers under Heading 84.32; (ii) Whether the demand was barred by limitation or could be sustained by invoking the extended period on the ground of suppression with intent to evade duty; (iii) Whether penalty under Section 11AC and interest under Section 11AB could be imposed for the period prior to 28-9-1996.

Issue (i): Whether the disputed goods were classifiable as parts of internal combustion engines under Heading 84.09 or as parts of power tillers under Heading 84.32.

Analysis: The goods were admittedly cleared for use in internal combustion engines and there was a specific tariff entry covering parts suitable for use solely or principally with engines of Heading 84.07 or 84.08. In such a situation, the classification had to follow the specific entry for engine parts rather than the claimed entry for power tiller parts. The alternative reliance on Section Note 2(b) did not arise because the goods were not merely general parts with no specific heading.

Conclusion: The classification under Heading 84.09 was upheld, and the assessee's claim to Heading 84.32 failed.

Issue (ii): Whether the demand was barred by limitation or could be sustained by invoking the extended period on the ground of suppression with intent to evade duty.

Analysis: The assessee had described the goods in classification lists as parts of power tillers while knowing that they were being used in internal combustion engines. The non-disclosure of the true nature of the goods in the declarations amounted to suppression of material facts. The plea of revenue neutrality through Modvat credit did not negate suppression where the goods were classified under a lower duty entry despite being correctly classifiable under a higher one.

Conclusion: The extended period of limitation was correctly invoked, and the demand was not time-barred.

Issue (iii): Whether penalty under Section 11AC and interest under Section 11AB could be imposed for the period prior to 28-9-1996.

Analysis: The provisions creating liability to penalty and interest were held to apply only from 28-9-1996. Accordingly, they could not be applied to the earlier part of the demand period, though they could operate prospectively thereafter.

Conclusion: Penalty and interest for the period prior to 28-9-1996 were not sustainable, and the penalty was directed to be re-determined with interest chargeable only from 28-9-1996 onwards.

Final Conclusion: The demand on classification and limitation was sustained, but the penalty and interest liability required modification in line with the prospective operation of the penal and interest provisions.
