Exemption for tubular steel poles and refund claims depend on actual classification and proof of unjust enrichment.

Tubular steel poles were treated as steel pipes and tubes for Tariff Item 26AA, so exemption under Notification No. 69/73 could not be denied merely because pipes and tubes arose at an intermediate stage in manufacture. For refund, unjust enrichment could not be inferred for the entire claim without evidence that duty had actually been passed on to customers; invoices were relevant evidence, and conjecture was insufficient. The amount admittedly recovered from customers was required to be credited to the Consumer Welfare Fund, while the remaining refund was allowed subject to that adjustment.

Issues: (i) Whether tubular steel poles were entitled to the benefit of Notification No. 69/73 on the footing that they were steel pipes and tubes falling under Tariff Item 26AA; (ii) Whether the refund claim was barred or reduced on the ground of unjust enrichment.

Issue (i): Whether tubular steel poles were entitled to the benefit of Notification No. 69/73 on the footing that they were steel pipes and tubes falling under Tariff Item 26AA.

Analysis: The classification settled by the Supreme Court treated tubular poles as steel pipes and tubes falling under Tariff Item 26AA. Once that position was accepted, the notification granting exemption to steel pipes and tubes could not be denied merely because pipes and tubes emerged at an intermediate stage in the manufacture of the final product. The intermediate stage was not decisive where the raw materials and the final product answered the description in the notification.

Conclusion: The benefit of Notification No. 69/73 was available and the objection based on inapplicability of the notification failed.

Issue (ii): Whether the refund claim was barred or reduced on the ground of unjust enrichment.

Analysis: Invoices are ordinarily the best evidence to determine whether duty has been passed on to customers. In the absence of evidence from the department that any amount over and above the admitted recovery had been collected, the finding that the entire refund claim was hit by unjust enrichment could not stand. The inference that the balance amount must also have been recovered was treated as based on conjecture rather than proof. The amount actually recovered from customers was, however, required to be credited to the Consumer Welfare Fund.

Conclusion: The plea of unjust enrichment did not defeat the refund claim in full, but the amount admittedly recovered from customers was not refundable to the assessee.

Final Conclusion: The appeal succeeded with consequential relief, and refund was directed subject to credit of the amount already recovered from customers to the Consumer Welfare Fund.

Ratio Decidendi: Where the final product is held to fall within the exempted description, exemption cannot be denied merely because the exempted goods emerge at an intermediate stage in manufacture, and unjust enrichment cannot be inferred for the entire refund claim without evidence that duty was actually passed on.
