Tariff classification of mica-based goods requires factual identification first, and remand is proper where evidence on product nature is incomplete.

Tariff classification of mica-based goods had to begin with objective identification of the goods before applying the relevant heading and interpretative rules. Since the record relied only on sample invoices, did not cover all clearances, and contained no finding on whether the goods were composite products or pure mica products, the proper classification could not be determined on the existing material. Chapter 68 covered mica products not elsewhere specified, while Chapter Note (g) excluded electrical insulators and insulating parts falling in Chapter 85. The matter was therefore remanded for fresh factual verification and a new classification decision.

Issues: Whether the mica-based goods were classifiable as articles of mica under Heading 68.07 or as insulators under Heading 85.46, and whether the matter required fresh adjudication on the identity and nature of the goods.

Analysis: Classification required first an objective identification of the goods and then application of the tariff description and interpretative rules. The record showed reliance on sample invoices indicating part and drawing numbers, but there was no finding on all clearances. The lower authorities also had not determined whether the goods were composite products or pure mica products. Heading 68.07 covered mica products not elsewhere specified or included, while Chapter Note (g) to Chapter 68 excluded electrical insulators and insulating parts falling in Chapter 85. On the existing material, a complete factual verification of the clearance documents and other evidence was necessary before deciding the proper heading.

Conclusion: The classification dispute was not finally adjudicated on the present record, and the matter was rightly remanded for a fresh factual examination and determination of classification.

Ratio Decidendi: Where the tariff classification of goods turns on their precise identity and the available evidence is insufficient to determine whether they are insulating parts or mica products, the adjudicating authority must first establish the factual nature of the goods before applying the relevant tariff heading.
