Essential character controls tariff classification when ancillary lubricating properties do not change a product's identity as hydraulic fluid.

Tariff classification turned on the product's essential character and commercial identity. Although the imported goods had lubricating and fire-resistant properties, the literature showed they were designed and traded as hydraulic fluid for aircraft hydraulic systems; those properties were only ancillary to a good hydraulic fluid. The goods were therefore not classifiable as a lubricating preparation under Heading 34.01/07(2) and did not qualify for Notification No. 32/83-Cus. The classification under Heading 34.01/07(1) was upheld, because an ancillary attribute does not alter the basic nature of the product.

Issues: Whether the imported product, though possessing lubricating and fire-resistant properties, was classifiable as a lubricating preparation under Heading 34.01/07(2) of the First Schedule to the Customs Tariff Act, 1975 and eligible for the benefit of Notification No. 32/83-Cus. dated 1-3-1983, or whether it remained classifiable as a hydraulic fluid under Heading 34.01/07(1).

Analysis: The product literature showed that the goods were hydraulic fluid designed for aircraft hydraulic systems and that their lubricating and fire-resistant qualities were ancillary attributes required of a good hydraulic fluid. The essential and basic character of the product was that of a hydraulic fluid. In commercial understanding also, it was known, traded and described as hydraulic fluid, not as a lubricating preparation.

Conclusion: The product was not classifiable as a lubricating preparation under Heading 34.01/07(2) and was not entitled to the claimed notification benefit. The classification under Heading 34.01/07(1) was upheld, against the assessee.

Final Conclusion: The appeal failed because the imported goods retained their identity as hydraulic fluid, with lubrication treated only as a subsidiary property.

Ratio Decidendi: For tariff classification, the essential character and commercial identity of the goods govern, and an ancillary property does not convert a product into a different tariff item when its basic nature remains unchanged.
