Duty on blended wool tops attaches at captive-use removal stage, with extended limitation available for suppressed assessment facts.

Duty on blended wool tops was stated to arise at the stage of removal for captive use in manufacturing woollen yarn, because the tariff treated pure wool tops and blended wool tops as the same excisable commodity and the collection rule fixed liability at the later removal stage. The text also states that suppression of the relevant assessment facts through failure to file declarations, classification lists and prescribed documents justified use of the extended limitation period, though the demand was confined prospectively from 3-12-1980 and patent computational errors had to be excluded. Penalties were described as justified because the non-disclosure was treated as deliberate non-compliance rather than a bona fide misunderstanding.

Issues: (i) Whether excise duty on blended wool tops containing more than 50% wool was payable at the stage of removal of blended wool tops for captive use in the manufacture of woollen yarn, and not at the earlier stage when pure wool tops were produced for blending. (ii) Whether the demands were barred by limitation and the extended period under the excise law was available. (iii) Whether the penalties for contravention of the excise rules were justified. (iv) Whether obvious computation mistakes in the demand required exclusion.

Issue (i): Whether excise duty on blended wool tops containing more than 50% wool was payable at the stage of removal of blended wool tops for captive use in the manufacture of woollen yarn, and not at the earlier stage when pure wool tops were produced for blending.

Analysis: The tariff entry covered both pure wool tops and blended wool tops, and the governing rule fixed payment at the stage of removal for manufacture of another commodity. Pure wool tops and blended wool tops were treated as the same excisable commodity under the entry, while removal for captive use in spinning woollen yarn attracted duty at the stage when blended wool tops were cleared for that further manufacture. The earlier stage of producing pure wool tops for blending was not the relevant stage of collection.

Conclusion: The duty was legally payable at the blended wool top stage, not at the pure wool top stage.

Issue (ii): Whether the demands were barred by limitation and the extended period under the excise law was available.

Analysis: The show cause notices, read with the prior correspondence and the assessee's admitted failure to file declarations, classification lists, and prescribed assessment documents for blended wool tops, disclosed suppression of the relevant facts. The assessee was under a self-removal regime, and the department could not be expected to infer the true assessment practice from selective visits or D-3 intimations. However, the demand for the period before the trade notice changing the assessment practice was considered inequitable, and the demand was confined prospectively from that date. Obvious computational mistakes were also required to be excluded.

Conclusion: The extended period was available, but the demand was restricted to the period from 3-12-1980 onward and any obvious calculation errors had to be excluded.

Issue (iii): Whether the penalties for contravention of the excise rules were justified.

Analysis: The assessee had not disclosed the blended wool tops in the prescribed declarations and persisted in the disputed practice even after the change in assessment was brought to its notice. The conduct was treated as deliberate non-compliance with the assessment requirements and not a bona fide misunderstanding.

Conclusion: The penalties were justified.

Issue (iv): Whether obvious computation mistakes in the demand required exclusion.

Analysis: Claims were made that the demand included non-dutiable quantities, goods outside the relevant category, and duplicated batches. The matter was treated as one requiring verification and exclusion of amounts attributable to patent mistakes.

Conclusion: The computation mistakes had to be examined and any amount attributable to obvious errors excluded.

Final Conclusion: The duty liability on blended wool tops was upheld in principle, the limitation defence failed, and the penalties were sustained, but relief was granted by restricting the demand to the period after 3-12-1980 and by directing exclusion of obvious computational mistakes.

Ratio Decidendi: Where excisable goods are removed for captive use in the manufacture of another commodity, duty is chargeable at the stage fixed by the statutory collection rule, and suppression of the relevant assessment facts justifies invocation of the extended limitation period.
