Consistent tariff classification applied to insoluble sulphur after prior Tribunal ruling was followed on the same issue.

Insoluble sulphur with 20% oil content was classified under heading 25.01/32(10) of the Customs Tariff Act rather than heading 38.01/19(7), because the Tribunal followed its earlier decision on the same classification question and found no reason to depart from it. The consistent application of that prior view determined the classification, and the appellants obtained consequential relief on that basis.

Issues: Whether insoluble sulphur with oil content 20% was classifiable under heading 25.01/32(10) of the Customs Tariff Act or under heading 38.01/19(7) of the Customs Tariff Act.

Analysis: The Tribunal noted that the very same classification question had already been decided in an earlier order and that the earlier view supported classification under heading 25.01/32(10). No reason was found to depart from that decision, and the earlier classification approach was followed.

Conclusion: Insoluble sulphur was held classifiable under heading 25.01/32(10) of the Customs Tariff Act and not under heading 38.01/19(7) of the Customs Tariff Act.

Final Conclusion: The appeals succeeded and the appellants were granted the consequential relief flowing from the classification under heading 25.01/32(10).

Ratio Decidendi: Where an earlier Tribunal decision directly covers the classification question and no reason exists to depart from it, the same classification should be applied consistently.
