Lubricating preparation classification for fat liquor supported exemption where leather-processing use matched the notification's language.

Fat liquor used in leather processing was treated as a lubricating preparation under Heading 34.03 because technical material and trade understanding showed it lubricated leather and reduced fibre cohesion. The exemption under Notification No. 13/92-C.E. was construed on its own language, and the HSN explanatory note could not override the notification's terms. On that basis, the product satisfied the description of a lubricating preparation, and the suggested distinction between a lubricating preparation and a preparation of a kind used in the leather industry did not defeat exemption. The Revenue's challenge therefore failed.

Issues: Whether fat liquor used in leather processing was a lubricating preparation falling under Heading 34.03 and eligible for exemption under Notification No. 13/92-C.E. dated 01.03.1992.

Analysis: The item was not in dispute as regards its classification under Heading 34.03 or its non-inclusion of petroleum oils or oils obtained from bituminous minerals. The lower authorities relied on technical literature and trade understanding to conclude that fat liquors are used to lubricate leather and reduce fibre cohesion, and therefore answer the description of lubricating preparations. The exemption notification was to be construed according to its own terms, and the HSN explanatory note could not override the language of the notification. Since the product satisfied the description of a lubricating preparation, the distinction suggested by the Revenue between a lubricating preparation and a preparation of a kind used in leather industry did not displace the exemption.

Conclusion: The product was held to be a lubricating preparation entitled to exemption, and the Revenue's challenge failed.
