Manufacture and exemption principles: mere shaping of rods is not manufacture, and mixed-material anodes can still qualify for exemption.

Bending or twisting M.S. rods or pipes into M.S. inserts for use in aluminium alloy anodes did not amount to manufacture because no new commercially known or marketable product emerged; the inserts remained rods or pipes in substance and were not excisable intermediate goods. Aluminium alloy anodes containing zinc and indium remained eligible for exemption because the notification did not require exclusive use of Chapter 76 goods, and the presence of other materials used for technological necessity did not defeat the exemption in the absence of restrictive words such as "exclusively" or "only."

Issues: (i) whether bending or twisting M.S. rods or pipes to make M.S. inserts amounted to manufacture of excisable goods; and (ii) whether aluminium alloy anodes manufactured with zinc and indium remained eligible for exemption under the notification.

Issue (i): whether bending or twisting M.S. rods or pipes to make M.S. inserts amounted to manufacture of excisable goods.

Analysis: The inserts were produced only by bending or twisting rods or pipes to suit the final use in aluminium alloy anodes. Such shaping did not bring into existence any commercially known or marketable product. Even after the change in shape, the items remained rods or pipes in substance and were used only as components in the anodes.

Conclusion: The process did not amount to manufacture, and the M.S. inserts were not excisable intermediate goods.

Issue (ii): whether aluminium alloy anodes manufactured with zinc and indium remained eligible for exemption under the notification.

Analysis: Aluminium alloys in which aluminium predominates by weight are covered by the same chapter, and the exemption notification did not require that the final product be made exclusively or only from goods of Chapter 76. Where the notification does not use restrictive words such as exclusively, only, or wholly, use of other materials does not by itself deny the exemption. On that basis, the presence of zinc and indium did not take the product outside the notification.

Conclusion: The aluminium alloy anodes were eligible for exemption under the notification.

Final Conclusion: The demands were unsustainable and the assessee succeeded on both issues, resulting in setting aside of the impugned orders.

Ratio Decidendi: In the absence of express restrictive words in an exemption notification, a product does not lose exemption merely because small quantities of other materials are used for technological necessity, and mere shaping of raw rods or pipes without emergence of a marketable new product does not constitute manufacture.
