Marketable waste and scrap from manufacture held dutiable; no deduction for invisible loss and extended limitation applied.

Waste and scrap generated during manufacture of railway parts was treated as a marketable commodity and therefore excisable as goods under the tariff heading. The claim for deduction on account of alleged invisible losses failed because no prior estimate, supporting evidence, or standard literature was produced. The demand was also held within the extended limitation period, as removal of scrap without duty payment was treated as involving suppression and the assessee was expected to know the duty liability arising from the job-work arrangement. Duty on the scrap was therefore sustained, with no deduction or limitation defence accepted.

Issues: (i) whether waste and scrap arising in the manufacture of railway parts was marketable and therefore excisable to duty under the tariff heading; (ii) whether any deduction was required on account of alleged invisible losses in the scrap quantity; and (iii) whether the demand was barred by limitation.

Issue (i): whether waste and scrap arising in the manufacture of railway parts was marketable and therefore excisable to duty under the tariff heading.

Analysis: Waste and scrap of iron and steel was treated as a recognised marketable commodity. The absence of a plea that the material was mere junk or scum was rejected, and the scrap generated during machining and other processes was held to be goods liable to duty under the tariff heading.

Conclusion: The issue was decided against the assessee and in favour of the Revenue.

Issue (ii): whether any deduction was required on account of alleged invisible losses in the scrap quantity.

Analysis: No estimate of invisible loss was furnished before the adjudicating authority or the Tribunal, and no acceptable evidence or standard literature was produced to support such a claim. In the absence of proof, no benefit could be granted on this ground.

Conclusion: The issue was decided against the assessee and in favour of the Revenue.

Issue (iii): whether the demand was barred by limitation.

Analysis: The removal of scrap without payment of duty was treated as a case attracting the extended period because the assessee was expected to know the duty liability arising under the permission granted for sending inputs to job workers. The Tribunal held that suppression was not ruled out and the longer limitation period was properly invoked.

Conclusion: The issue was decided against the assessee and in favour of the Revenue.

Final Conclusion: The order confirmed duty on waste and scrap, declined any deduction for alleged invisible loss, upheld invocation of the extended limitation period, and left no relief to the assessee.

Ratio Decidendi: Waste and scrap generated in the course of manufacture is dutiable when it is marketable, and in the absence of proof of invisible loss or any valid limitation defence, the duty demand can be sustained under the extended period.
