Classification of ores versus concentrates: conversion into concentrates treated as manufacture; exemption denied and duty with interest recovered.

Classification of ores versus concentrates is examined, concluding that processing of run-of-mine ore by screening, sizing, crushing and removal of overburden resulting in concentrates constitutes manufacture by virtue of deeming provisions; consequently such concentrates qualify as distinct excisable goods and are not eligible for the claimed exemption under the relevant notification which must be strictly construed. The text further confirms that statutory interest is payable for delayed duty and that recovery of differential duty along with applicable interest is warranted where exemption is disallowed.

Issues: (i) Whether the imported material, after having undergone processes such as crushing, screening, sizing and washing prior to shipment, constitutes a concentrate (and thus a distinct, excisable product under Chapter Note 4 to Chapter 26) thereby disentitling it to exemption under Notification No.4/2006-C.E.; (ii) Whether interest is payable on differential duty demanded where provisional assessment was made and exemption was denied on adjudication.

Issue (i): Whether the pre-shipment processes undertaken on Run-of-Mine (ROM) manganese ore resulted in conversion into concentrate amounting to manufacture and excluded the goods from exemption under Notification No.4/2006-C.E.

Analysis: The Tribunal examined Chapter Note 4 to Chapter 26, HSN explanatory notes and the CBIC/MoM clarification (F.No.332/1/2012-TRU dt.17.01.2012). It considered precedent and later authoritative rulings holding that by virtue of the deeming provision conversion of ores into concentrates amounts to manufacture and that any activity carried out on ROM ore with the intent to remove foreign matter partly or fully, so as to make it suitable for metallurgical purposes or economical transport, would effect conversion into a concentrate. The Tribunal distinguished coordinate decisions which treated crushing/screening as mere preparatory processes, noting they did not sufficiently take into account the Supreme Courts observations in Star Industries and the effect of the inserted Chapter Note 4. The Tribunal also considered evidence and admitted facts that crushing, screening, sizing and washing were carried out before shipment and that the imported ore had improved manganese content consistent with sub-classification under Chapter 2602.

Conclusion: The processes undertaken on the ROM manganese ore amounted to conversion into a concentrate (deemed manufacture) within the meaning of Chapter Note 4 to Chapter 26; therefore the imported goods were not entitled to exemption under Notification No.4/2006-C.E. The appeal on classification is dismissed in favour of Revenue.

Issue (ii): Whether interest on the differential duty can be demanded in the facts of the case.

Analysis: The Tribunal applied statutory provisions governing duty and interest for delayed payment and followed precedent holding that where duty is found due on adjudication, applicable interest is payable. The Tribunal rejected the appellants' contention that provisional assessment precludes demand of interest where exemption is later denied.

Conclusion: Interest is payable on the differential duty found due; the appellants are liable for interest along with the duty. This conclusion is against the appellant.

Final Conclusion: The Tribunal concluded that, on the admitted facts and in light of the deeming provision in Chapter Note 4 to Chapter 26 and applicable authority, the imported manganese material is a concentrate and not eligible for exemption under Notification No.4/2006-C.E., and that statutory interest on the differential duty is payable; the appeal is dismissed.

Ratio Decidendi: Where Chapter Note 4 to Chapter 26 deems the process of converting ores into concentrates as manufacture, any pre-shipment activity carried out with the effect of removing foreign matter partly or wholly so as to upgrade ore for metallurgical use or economical transport results in a distinct excisable product (concentrate) and excludes the goods from exemption notifications applicable only to ores.
