Tariff classification follows dominant use: flushing oil was excluded from blended lubricating oil entry because solvent function prevailed.

Salt Flushing Oil was held outside Tariff Item 11B because its dominant character was solvent flushing, used to remove deposits from crank cases and gear boxes after draining used lubricant. Its lubricating quality was treated as secondary, so it did not answer the description of blended lubricating oil and greases. The classification under the disputed tariff entry was therefore rejected, the impugned appellate classification was set aside, and the revision application was allowed. The governing principle stated is that tariff classification depends on the primary and dominant use of the product where that use does not match the essential character of the claimed entry.

Issues: Whether Salt Flushing Oil was correctly classified under Tariff Item 11B of the Central Excise Tariff as blended lubricating oil and greases.

Analysis: The oil was found to be primarily used for flushing out deposits from the crank case and gear box after draining used lubricant. Its solvent character and flushing function were treated as dominant, while its lubricating quality was considered only secondary. On that basis, the product did not answer the description of blended lubricating oil and greases for classification under Item 11B.

Conclusion: Salt Flushing Oil was not classifiable under Tariff Item 11B and the assessee succeeded in revision.

Final Conclusion: The impugned appellate classification was set aside and the revision application was allowed, with the product held outside the disputed tariff entry.

Ratio Decidendi: For tariff classification, the primary and dominant use of a product governs its classification where the alleged classification entry describes a different essential character.
