Provisional excise assessment and re-test results controlled classification and defeated the limitation plea on differential duty.

On provisional central excise assessment based on chemical testing, the assessee sought re-test of samples and was bound by the re-test results once obtained. Applying the technical test parameters of flashing point, flame height, bituminous content and viscosity, the Tribunal classified some consignments under Tariff Item 8 as refined diesel oil and vapourising oil, and others under Tariff Item 9 as diesel oil not otherwise specified, thereby upholding the classification adopted below. As the assessments were provisional under bond and subject to test results, the plea that differential duty demands were time-barred under the limitation rule failed.

Issues: (i) Whether the goods, on the basis of the re-test results of the samples, were classifiable under Tariff Item 8 or Tariff Item 9 of the Central Excise Tariff. (ii) Whether the demands for differential duty in two cases were barred by limitation.

Issue (i): Whether the goods, on the basis of the re-test results of the samples, were classifiable under Tariff Item 8 or Tariff Item 9 of the Central Excise Tariff.

Analysis: The samples were re-tested by the Chief Chemist at the request of the appellants. The Tribunal held that the appellants were bound by the re-test results and could not subsequently contend that those results were unreliable. Classification had to be determined on the basis of the re-test results. Applying the technical parameters of flashing point, flame height, bituminous content and viscosity to the respective samples, the Tribunal concluded that some consignments fell under Tariff Item 8 as refined diesel oil and vapourising oil, while others fell under Tariff Item 9 as diesel oil not otherwise specified.

Conclusion: The classification adopted by the lower authority was upheld on the basis of the re-test results, and the goods were correctly assessed under Tariff Items 8 and 9, as applicable.

Issue (ii): Whether the demands for differential duty in two cases were barred by limitation.

Analysis: The Tribunal accepted the Revenue's position that the assessments were provisional and subject to chemical test, with the appellants having executed the relevant bond under Rule 9-B of the Central Excise Rules. In that situation, the plea of limitation under Rule 10 of the Central Excise Rules did not survive.

Conclusion: The plea of limitation was rejected.

Final Conclusion: The orders confirming the differential duty were sustained in full and the appeals failed.

Ratio Decidendi: Where assessment is provisional and the assessee seeks re-test of samples, classification and duty liability are determined on the basis of the re-test results, and the normal limitation plea does not apply in the same manner.
