Technical-standard tariff classification requires complete testing; partial internal reports cannot sustain an LDO demand for SRGO clearances.
Classification of SRGO as Light Diesel Oil requires proof that it conforms to the applicable Indian Standard specification, particularly after IS 15770:2008 replaced the earlier LDO standard. Reliance on internal transportation reports testing only limited parameters cannot establish conformity where the prescribed standard requires comprehensive testing. The demand therefore lacked an adequate evidentiary basis. Subsequent processing at other units and duty payment on the final cleared product also supported revenue neutrality, as no net revenue gain arose. The central principle is that a tariff classification incorporating an external technical standard must be supported by reliable, complete testing against that standard.
Issues: (i) Whether SRGO cleared by the appellant to its own units could be classified as Light Diesel Oil under the tariff definition linked to IS 1460/IS 15770 specifications. (ii) Whether the demand could be sustained on the basis of internal test reports and in the absence of full sample testing against all prescribed parameters. (iii) Whether the dispute was rendered revenue neutral by subsequent duty payment after processing in the appellant's other plants.
Issue (i): Whether SRGO cleared by the appellant to its own units could be classified as Light Diesel Oil under the tariff definition linked to IS 1460/IS 15770 specifications.
Analysis: The tariff entry treated Light Diesel Oil as hydrocarbon oil conforming to the relevant Indian Standard specifications. After the 2008 change, IS 1460 ceased to govern LDO and a separate specification, IS 15770:2008, was introduced. The revenue proceeded on the basis that SRGO matched the older standard, but the applicable specification had changed, and the record did not show conformity with the full requirements of either standard.
Conclusion: The classification of SRGO as LDO was not established.
Issue (ii): Whether the demand could be sustained on the basis of internal test reports and in the absence of full sample testing against all prescribed parameters.
Analysis: The revenue did not draw independent samples and relied on the appellant's internal transportation reports, which covered only a few parameters. Those reports did not test the large number of parameters required by the applicable standards. In the absence of complete testing and conformity with the prescribed specifications, the evidentiary basis for the demand was insufficient.
Conclusion: The demand could not be sustained on the basis of the internal reports alone.
Issue (iii): Whether the dispute was rendered revenue neutral by subsequent duty payment after processing in the appellant's other plants.
Analysis: The same product was processed in the appellant's other units and duty was paid on the cleared final product. This supported the plea that the entire exercise did not result in any net revenue gain to the department.
Conclusion: The matter was revenue neutral.
Final Conclusion: The appeal succeeded because the department failed to prove that the product answered the applicable LDO specification, and the surrounding facts also supported revenue neutrality.
Ratio Decidendi: Where a tariff entry incorporates an external technical standard, the department must prove conformity with the applicable standard by reliable and complete testing of the goods; partial internal reports are insufficient to sustain classification and demand.
