Protective coating on MS pipes was not manufacture absent a distinct product or applicable deeming provision.

Applying the general test of manufacture, coating bare MS pipes with coal tar enamel or polyethylene did not create a new product with a distinct name, character or use, because the goods remained commercially known as MS pipes. The relevant deeming provision in Chapter Note 5 to Chapter 73, as it stood before 18 April 2006, covered only headings 73.04 and 73.05; its extension to heading 73.06 came only by amendment under the Finance Act, 2006 and was not retrospective. The coating process therefore fell outside the pre-amendment deeming fiction, so it did not amount to manufacture during the material period and no excise duty was payable.

Issues: Whether coating bare MS pipes with coal tar enamel or polyethylene amounted to manufacture during the relevant period, so as to attract excise duty.

Analysis: The coated pipes were processed by cleaning, heating, spraying, and applying protective coatings, but the goods continued to be commercially known as MS pipes and there was no change in name, character, or use. The general test of manufacture requires emergence of a new product with a distinct identity, unless a statutory deeming provision applies. Chapter Note 5 to Chapter 73, as it stood before 18-4-2006, covered only headings 73.04 and 73.05, and its extension to heading 73.06 came only by amendment under the Finance Act, 2006. That amendment was held not to operate retrospectively. On that basis, the process was outside the pre-amendment deeming provision.

Conclusion: The coating activity did not amount to manufacture during the material period, and no excise duty was payable on the coated pipes.

Ratio Decidendi: A protective coating on MS pipes does not amount to manufacture unless it produces a commercially distinct product or is brought within a valid deeming provision in force for the relevant period.
