Manufacture and limitation in excise: processing copper tubes changed their identity, but disclosed classification claims defeated suppression for the first demand.

Cutting, bending, grinding and smoothening duty-paid copper tubes into buyer-specific components changed their identity, character and use; the activity was treated as manufacture under Section 2(f) of the Central Excise Act, 1944 and the goods were classifiable as parts of gas compressors. For limitation, disclosure of the processing activity and the assessee's view in the classification list meant suppression was not established, so the earliest demand was time-barred under Section 11A, while later notices were within limitation. On penalty, the absence of suppression and the disclosed bona fide stand removed the factual basis for penalty, which was set aside.

Issues: (i) Whether cutting, bending, grinding and smoothening of duty-paid copper tubes resulted in manufacture and made the goods classifiable as parts of gas compressors; (ii) whether the demand for the first notice was barred by limitation and the extended period could be invoked; (iii) whether penalty was sustainable.

Issue (i): Whether cutting, bending, grinding and smoothening of duty-paid copper tubes resulted in manufacture and made the goods classifiable as parts of gas compressors.

Analysis: The processed tubes were no longer sold or understood in trade parlance as ordinary copper tubes or pipes. They were cut to specific dimensions, bent and further processed according to buyer requirements, and their character, use and identity changed into distinct components used only for gas compressor equipment. Such transformation satisfied the test of manufacture under Section 2(f) of the Central Excise Act, 1944.

Conclusion: The process amounted to manufacture and the goods were correctly classifiable as parts of gas compressors.

Issue (ii): Whether the demand for the first notice was barred by limitation and the extended period could be invoked.

Analysis: The assessee had disclosed the nature of the process in the classification list and had stated its view that the activity was not manufacture. In the presence of such disclosure, suppression could not be alleged for the earlier period and the Revenue was expected to verify the declaration within the normal period under Section 11A of the Central Excise Act, 1944. The first notice was therefore time-barred, while the later notices were within limitation.

Conclusion: The first demand was barred by limitation, but the subsequent demands were upheld.

Issue (iii): Whether penalty was sustainable.

Analysis: Since the assessee had made a fair disclosure of its stand in the classification list and suppression was not established for the relevant period, the factual foundation for penalty was absent.

Conclusion: The penalty was set aside.

Final Conclusion: The classification and manufacture findings were sustained, the earliest demand failed on limitation, the later demands survived, and the penalty was deleted, resulting in a partial allowance of the appeal.

Ratio Decidendi: When duty-paid goods undergo processing that changes their identity, character and use so that they are understood in trade as different articles, the activity amounts to manufacture; but a disclosed bona fide classification stand negates suppression for invoking the extended limitation period.
