Tariff classification of Light Diesel Oil depends on proof of full technical-standard compliance, not partial internal test reports.

Where a tariff entry for Light Diesel Oil incorporates external technical standards, classification depends on proof that the product conforms to the applicable Indian Standard in force at the relevant time. The article notes that after the 2008 change, IS 1460 no longer governed LDO and IS 15770:2008 applied, yet the record did not establish conformity with the full requirements of either standard. It also states that internal transportation reports covering only limited parameters, without independent sampling and complete testing, were insufficient to support the demand. The text further records that processing and duty payment in other plants supported a plea of revenue neutrality.

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.
