Commissioner of Customs, Kandla v. M/s Reliance Industries Ltd.
Background
Reliance Industries imported a chemical called "n-Hexane" (also called Exxsol Hexane) and classified it under Customs/Excise Tariff heading 2901, applicable to pure chemical compounds, which attracts a lower rate of duty. The Customs Department disagreed, relying on a chemical test report showing the product's distillation range and flash point, and sought to reclassify it as "Motor Spirit" under heading 2710 (covering mineral/petroleum oils), which attracts higher duty. This classification dispute journeyed through the Assistant Commissioner, the Commissioner (Appeals), and the CESTAT tribunal, all of which ultimately ruled in favour of Reliance, before the Revenue appealed to the Supreme Court.
Decision Breakdown
The Supreme Court dismissed the Revenue's appeal and upheld the CESTAT's ruling that n-Hexane is properly classifiable under Chapter 29 (as a separate chemical compound), not Chapter 27. It held the Revenue failed to discharge its initial burden of proving the product was a "Motor Spirit" mixture, relying only on distillation and flash-point figures without other supporting evidence. The Court applied Rule 3(a) of the General Rules of Interpretation guided by the internationally recognised Harmonized System Notes, which specifically identify Hexane under Chapter 29, and further noted that the impurities found were merely unconverted starting materials, not deliberately added substances. It also gave weight to a binding DGFT Policy Circular that had already clarified Hexane's classification under Chapter 29.
Lesson Learnt
In tax/customs classification disputes, the burden of proof lies on the authority seeking to reclassify goods into a higher-duty category, and it must be discharged with proper evidence: mere reliance on isolated chemical parameters (like flash point) is not enough when internationally recognised classification notes and government policy circulars point the other way.
