Tribunal overturns duty demand on synthetic diamond polishing powder, citing process discrepancies.

The Tribunal allowed the appeals, setting aside the Commissioner's order demanding duty and penalties on the appellant for manufacturing synthetic diamond polishing powder. The Tribunal found that the appellant's processes, including treating imported uncoated powder with chemicals and grading it for different applications, did not clearly constitute manufacturing due to discrepancies in the appellant's declarations. The Tribunal concluded that the processes were more akin to impurity removal and enhancing powder utilization for cutting diamonds, thus rejecting the invocation of the extended limitation period.

Issues:
1. Whether the appellant was engaged in the manufacture of synthetic diamond polishing powder.
2. Whether the processes undertaken by the appellant amount to manufacture.
3. Whether the extended period of limitation was correctly invoked by the Commissioner.

Analysis:
1. The appeals challenged the Commissioner's order holding the appellant engaged in manufacturing synthetic diamond polishing powder and demanding duty, along with penalties on the appellant and its directors. The appellant imported synthetic diamond powder, selling copper-coated powder as imported and utilizing uncoated powder in manufacturing diamond-coated articles after treating with caustic soda and sulphuric acid. The Tribunal previously held such processes were not manufacturing but impurity removal, enhancing powder utilization for cutting diamonds.

2. The Tribunal refrained from deciding if the appellant's processes constituted manufacturing due to discrepancies in the appellant's declarations. The appellant's declarations indicated grading the powder into various sizes for different applications, potentially constituting manufacturing. However, the appellant argued that sieving was random to verify product size, which could impact the issue significantly. The inconsistent declarations prevented a clear determination on whether the processes amounted to manufacturing.

3. The Commissioner invoked the extended limitation period, alleging transformation of goods from industrial synthetic fiber to diamond polishing powder. The Tribunal disagreed, stating that cleaning the product did not result in a new substance's emergence. The possibility of sieving creating different grades for varied applications potentially constituting manufacturing was considered. As the appellant's declarations clearly mentioned sieving for grading, the information available to the Commissioner negated the need for the extended limitation period, leading to the appeals being allowed and the impugned order set aside.
