Manufacture by repacking and quality processing of bulk gas can trigger excise duty and extended limitation for suppression.

Testing, grading, purification and repacking of bulk helium gas, together with issuance of quality certificates, amounted to manufacture under Chapter Note 10 because the process produced a commercially distinct and more marketable product; excise duty was therefore payable. The extended limitation period was also correctly invoked because the assessee did not disclose the nature of the treatment applied to the gas and failed to pay duty on the cleared product, which constituted suppression of material facts. The Tribunal's view sustaining duty liability and limitation was upheld.

Issues: (i) whether the testing, grading, purification, repacking and issuance of quality certificates in relation to Helium gas amounted to manufacture under Chapter Note 10 of Chapter 28 of the Central Excise Tariff Act, 1985; (ii) whether the extended period of limitation was invocable on the facts of the case.

Issue (i): whether the testing, grading, purification, repacking and issuance of quality certificates in relation to Helium gas amounted to manufacture under Chapter Note 10 of Chapter 28 of the Central Excise Tariff Act, 1985.

Analysis: Chapter Note 10 treats labelling or relabelling of containers, repacking from bulk to retail packs, and any other treatment that renders the product marketable to the consumer as manufacture. The gas was purchased in bulk, subjected to tests and analysis, segregated into different grades, supplied in different cylinders with separate certificates, and sold at substantially higher prices. These steps resulted in a commercially different and more marketable product, not a sale of the gas as originally purchased.

Conclusion: The process amounted to manufacture and excise duty was payable.

Issue (ii): whether the extended period of limitation was invocable on the facts of the case.

Analysis: The record showed that the appellant did not disclose the nature of the treatment undertaken on the gas and did not pay duty on the cleared product. The authorities therefore had a basis to treat the non-disclosure as suppression of material facts.

Conclusion: The extended period of limitation was rightly invoked.

Final Conclusion: The appeal failed, and the Tribunal's view sustaining duty liability and limitation was upheld.

Ratio Decidendi: Where bulk goods are subjected to testing, grading, repacking or similar treatment that gives them distinct marketability to consumers, the process amounts to manufacture under the relevant tariff note; concealment of such treatment can justify invocation of the extended limitation period.
