Customs tariff classification must rest on evidence and interpretative rules, not unsupported reclassification of imported goods.

Tariff classification of imported goods was examined between heading 3505 for modified starches and heading 3824 for prepared additives for cements, mortars or concretes. Classification had to be made under the General Rules for Interpretation of the Import Tariff, and the revenue bore the burden of proving a departure from the declared heading. The reclassification was found unsustainable because it rested on limited material, did not establish that the goods answered the specific description in heading 3505, and failed to assess the claim that the goods were cement and mortar additives. The classification, duty and penalty determinations were set aside and the matter was remanded for fresh adjudication.

Issues: Whether the imported goods were correctly classifiable under heading 3505 of the First Schedule to the Customs Tariff Act, 1975 or under heading 3824 of the First Schedule to the Customs Tariff Act, 1975, and whether the impugned orders could be sustained without proper tariff-item level justification.

Analysis: The classification dispute turned on the competing descriptions of the goods as modified starches under heading 3505 or as prepared additives for cements, mortars or concretes under heading 3824. The burden to justify a departure from the declared classification lay on the revenue, and classification had to be determined in accordance with the General Rules for Interpretation of the Import Tariff. The finding of reclassification was found unsustainable because the authorities relied on limited materials, did not establish that the goods answered the specific description under heading 3505, and failed to examine the appellant's claim that the goods were used as cement and mortar additives. The residuary character of heading 3824 did not permit rejection of the appellant's claim without a proper, comprehensive determination of the relevant tariff item and supporting evidence.

Conclusion: The impugned classification and consequential duty and penalty determinations were set aside, and the matter was remanded for fresh adjudication.

Final Conclusion: The appeals succeeded to the extent that the earlier orders were annulled and the classification dispute was reopened for de novo consideration by the original authorities.

Ratio Decidendi: In tariff classification disputes, the revenue must discharge the burden of proving a different heading from that declared, and a specific tariff description cannot be rejected without a reasoned, evidence-based determination under the interpretative rules.
