Modvat credit for steel shots used in shot blasting turns on whether they are independent tools or machine-assisted process inputs

Steel shots used in shot blasting were treated as part of the machine-assisted process, not as independent tools capable of performing the operation by themselves. Applying the Larger Bench view on the meaning of "tools" in the Explanation to Rule 57A of the Central Excise Rules, 1944, they were held outside the excluded category for Modvat purposes. The departmental challenge to Modvat credit therefore failed.

Issues: Whether steel shots used in the shot blasting process were inputs eligible for Modvat credit under Rule 57A of the Central Excise Rules, 1944, or whether they were merely tools excluded from the Explanation to that rule.

Analysis: The relevant test was whether the article in question was itself a complete instrument capable of performing the operation for which it was intended. Steel shots did not by themselves remove rust or impurities from the steel sheets. They were projected at high velocity by the shot blasting machine, and the loosening of particles occurred because of the impact generated by the machine-assisted process. On that basis, the shots were not independent tools but only parts of the equipment used in the operation. Applying the Larger Bench view on the meaning of "tools" in the Explanation to Rule 57A, such articles could not be treated as falling within the excluded category.

Conclusion: Steel shots were not inputs within the meaning of Rule 57A and were excluded as tools. The departmental challenge to Modvat credit therefore failed.
