Exemption for post-assessment yarn waste denied where duty-paid yarn was later consumed in weaving and lap waste arose thereafter.

Duty paid on yarn at the stage of removal and assessment remained complete even after the yarn was later consumed in weaving, so lap waste arising during that captive use did not fall within the exemption notification. The Tribunal held that the notification could apply only where the waste yarn itself was presented for assessment and removal under the relevant rules; post-assessment waste from duty-paid yarn was therefore outside its scope. The plea of discrimination was rejected because the notification applied uniformly to waste yarn under the tariff entry regardless of cotton content. The time-bar objection was not decided, as the claim failed on the substantive issue.

Issues: Whether lap waste arising after duty-paid yarn had been assessed and removed for captive use in weaving was eligible for refund under the exemption notification, and whether the refund claim was time-barred.

Analysis: Excise is a tax on manufacture, and under the normal procedure duty is payable when the goods are removed and assessed in the form in which they are presented. Once warp beams of yarn had been assessed, duty paid, and then consumed in weaving, any waste arising thereafter in the course of such consumption could not alter the completed assessment. The exemption notification could apply only where waste yarn itself was presented for assessment and removal in accordance with the relevant rules. Lap waste arising after the assessment of duty-paid yarn in the weaving process was therefore outside the scope of the notification. The Tribunal found no basis for the discrimination plea, because the notification applied uniformly to waste yarn under the tariff entry regardless of cotton content. It found it unnecessary to decide the time-bar objection.

Conclusion: The lap waste was not entitled to refund under the notification, and the refund claim failed on the substantive ground.

Final Conclusion: The appeal was rejected because post-assessment waste arising from duty-paid yarn used in weaving did not qualify for the exemption or refund claimed.

Ratio Decidendi: Where duty has already been validly assessed and paid on goods at the stage of removal, waste arising later in the course of their captive use or consumption is not eligible for refund unless the governing exemption specifically covers such post-assessment waste.
