Chemical processing beyond normal ore concentration supports Chapter 28 classification for scheelite concentrate, not tungsten ore heading.

A short delay in filing the appeal was condoned because it was explained by the incorrect appellate address in the lower order, and the appeal had otherwise been presented at the stated address. On classification, scheelite concentrate described as Australian King Island scheelite tungsten ore was held not to fall under Heading 2611.00, because the evidence showed further chemical processing beyond normal metallurgical concentration; as a chemically precipitated, separately defined calcium tungstate product, it was classifiable under Chapter 28 instead. The departmental classification challenge therefore failed.

Issues: (i) Whether the delay of 9 days in filing the appeal before the Collector (Appeals) was condonable. (ii) Whether scheelite concentrate described as Australian King Island scheelite tungsten ore was classifiable under Heading 2611.00 of Chapter 26 or as inorganic chemical calcium tungstate under Chapter 28.

Issue (i): Whether the delay of 9 days in filing the appeal before the Collector (Appeals) was condonable.

Analysis: The delay was short and was explained by the incorrect address of the appellate authority mentioned in the preamble of the lower order. The appeal had otherwise been presented at the address indicated in the order, and the Collector (Appeals) had also examined the merits.

Conclusion: The delay was condoned.

Issue (ii): Whether scheelite concentrate described as Australian King Island scheelite tungsten ore was classifiable under Heading 2611.00 of Chapter 26 or as inorganic chemical calcium tungstate under Chapter 28.

Analysis: Chapter 26 covers tungsten ores and concentrates, but Chapter Note 2 excludes minerals subjected to processes not normal to the metallurgical industry. The supplier's literature and the packing certificate described the product as artificial scheelite, high-purity calcium tungstate, and a fine chemically precipitated product obtained after further processing such as digestion, filtering, and chemical precipitation. The Customs House report described the sample as inorganic chemical calcium tungstate in white powder form. Although reliance was placed on the view that powder form alone is immaterial and that ore concentration may not destroy ore character, the evidence showed that the imported product was a further chemically processed product beyond normal ore concentration.

Conclusion: The goods were not classifiable under Heading 2611.00 and were correctly classified under Chapter 28 as inorganic chemical tungstate.

Final Conclusion: The challenge to the departmental classification failed, and the classification adopted against the importer was upheld.

Ratio Decidendi: Where a mineral product has undergone processes beyond normal metallurgical concentration and is shown by the evidence to be a chemically precipitated, separate chemically defined compound, Chapter 26 is excluded by Chapter Note 2 and classification must follow Chapter 28.
