Coal classification dispute: unsupported calorific value reworking could not displace steam coal classification or linked exemption.

Coal classification under Chapter 27 depended on reliable evidence that the imported goods met the higher-duty entry. The Tribunal found that the department's reworking of gross calorific value through a conversion formula was not scientifically or legally justified, and the load-port certificates and sampling record did not show fraud or mismatch. The declared classification as steam coal was therefore accepted, and the exemption linked to that tariff treatment remained available. Once that classification stood, the customs demand, interest, and consequential duty reworking under section 28 of the Customs Act lost their basis and were unsustainable.

Issues: (i) Whether the imported coal was classifiable as bituminous coal on the basis of the department's reworked gross calorific value and conversion formula, or as steam coal under the claimed tariff item. (ii) Whether denial of the concessional benefit under the exemption notification and the resulting customs demand could be sustained.

Issue (i): Whether the imported coal was classifiable as bituminous coal on the basis of the department's reworked gross calorific value and conversion formula, or as steam coal under the claimed tariff item.

Analysis: The classification turned on the meaning and effect of the chapter notes and the tariff hierarchy in Chapter 27 of the Customs Tariff Act, 1975. The load-port certificates and sampling reports showed gross calorific value and other parameters on the basis adopted for the import documentation, and the record did not show any fraud or mismatch of the samples. The reclassification rested on a mathematical conversion exercise using Parr formula and further adjustments between different measuring bases, but the conversion method was not shown to be scientifically or legally justified for the purpose of tariff classification. The Tribunal held that the department had not established that the declared coal failed the conditions for steam coal and that the attempt to push the goods into the bituminous coal entry was unsupported.

Conclusion: The imported goods were not held to be bituminous coal, and the assessee's classification as steam coal was accepted.

Issue (ii): Whether denial of the concessional benefit under the exemption notification and the resulting customs demand could be sustained.

Analysis: The exemption under Notification No. 12/2012-Cus was linked to the tariff treatment of steam coal. Once the declared classification was accepted, the foundation for the demand raised under section 28 of the Customs Act, 1962 fell away. The demand, interest liability, and consequential reworking of duty were therefore unsustainable, and the earlier compelled deposit was treated as warranting consequential relief.

Conclusion: Denial of the exemption was not justified and the customs demand could not be sustained.

Final Conclusion: The appeal succeeded, the impugned order was set aside, and the assessee retained the benefit of the declared classification and exemption.

Ratio Decidendi: For tariff classification of coal, the department must prove by reliable evidence that the goods satisfy the higher-duty entry; unsupported mathematical reworking of laboratory values cannot displace the declared classification or defeat the exemption attached to it.
