Technical evidence controls tariff classification where residual crude oil retains its character and reclassification is unjustified.

Residual crude petroleum oil generated during manufacture was treated as classifiable under Tariff Item 2709.00.00, because the technical evidence, including an IIT New Delhi report, showed that the product retained the character of crude oil. The revenue could not displace that technical finding or show any sufficient reason to reject the certificate on the nature of the goods. The appellate view on classification was therefore sustained, and the proposed reclassification under Tariff Item 2713 90 00 did not prevail; the demand and penalty based on that reclassification were not sustained.

Issues: Whether the residual crude petroleum oil arising in the manufacture of organic composite solvent was classifiable under Tariff Item No. 2709.00.00 of the First Schedule to the Central Excise Tariff Act, 1985 or under Tariff Item No. 2713 90 00, and whether the revenue could displace the technical report relied upon by the assessee.

Analysis: The classification dispute turned on the true nature of the leftover product generated during manufacture. The assessee relied on a report from IIT, New Delhi indicating that the product remained crude oil in character, and this technical evidence was accepted by the appellate authority. No sufficient ground was shown to dislodge that finding or to reject the certificate on the nature of the goods. In the absence of any reason to interfere with the factual and technical conclusion reached below, the classification adopted by the appellate authority was sustained.

Conclusion: The residual crude oil was held classifiable under Tariff Item No. 2709.00.00 and not under Tariff Item No. 2713 90 00; the revenue's appeal failed.

Final Conclusion: The demand and penalty based on reclassification of the product were not sustained, and the assessee's classification was upheld.

Ratio Decidendi: Where the technical evidence establishes the nature of the product as crude oil, and no convincing ground is shown to reject that evidence, the product must be classified according to its established character under the tariff.
