Manufacture by twisting and doubling yarn creates a distinct marketable product, and an unchallenged classification cannot be attacked through refund.

Doubling and twisting separately finished duty-paid polyester yarn and rayon filament yarn into PPRF was treated as manufacture because the resulting product emerged as a distinct, marketable yarn with a separate commercial identity and use; classification under the residuary tariff entry was therefore upheld. The refund claim also failed because the assessee had not effectively challenged the approved classification at the relevant stage and could not later use refund proceedings to question the levy collaterally. The order sustaining the residuary classification and rejecting refund was maintained.

Issues: (i) whether the product obtained by doubling and twisting duty-paid polyester yarn and rayon filament yarn into PPRF amounted to manufacture of a new excisable commodity classifiable under the residuary tariff item; (ii) whether the refund claim could succeed when the approved classification list had not been effectively challenged at the relevant stage.

Issue (i): Whether the product obtained by doubling and twisting duty-paid polyester yarn and rayon filament yarn into PPRF amounted to manufacture of a new excisable commodity classifiable under the residuary tariff item.

Analysis: The product was held to be a distinct finished yarn marketed under a separate trade name and produced by combining two separately finished yarns for a different commercial use. The Court distinguished cases dealing with mere intermediary processes and held that the present product satisfied the test of marketability and emergence of a new commodity. The plea that twisting did not amount to manufacture, or that the goods continued to remain the same yarn as the inputs, was rejected. The claim that the product should fall within the specific yarn entries was also negatived, and the residuary classification was upheld.

Conclusion: The product was rightly treated as a new excisable commodity classifiable under the residuary tariff item, against the assessee.

Issue (ii): Whether the refund claim could succeed when the approved classification list had not been effectively challenged at the relevant stage.

Analysis: The Court accepted the departmental view that the assessee had not disputed the classification in the manner required at the classification stage and could not later obtain refund by challenging the same levy collaterally. On that footing, the refund claim was held to be unsustainable.

Conclusion: The refund claim was not maintainable, against the assessee.

Final Conclusion: The order classifying the goods under the residuary entry and rejecting the refund claim was sustained, and the appeal failed.

Ratio Decidendi: Where twisting and doubling of separately finished duty-paid yarns produces a distinct marketable product sold under a separate commercial identity, the process amounts to manufacture and the resultant goods may fall under the residuary excise entry; a refund claim cannot override an unchallenged or accepted classification determination.
