Essential character governs composite goods classification; extended limitation fails where product composition was already known and approved.

Composite goods are classified by their essential character: aluminium foil laminated between plastic layers and used for pouches was held to fall under chapter 39 because the plastic predominated by weight and gave the product its essential character. The earlier authorities cited by the assessee were distinguished on facts, so the product was not treated as plain aluminium foil under chapter 76. On limitation, the extended period was not available because the department already knew the product's composition and the classification had been approved; the related penalty and interest therefore could not survive. The duty classification was sustained on merits, but the extended demand, penalty and interest were deleted.

Issues: (i) Whether aluminium foil laminated with plastic layers and the resulting pouches were classifiable under chapter 39 or chapter 76; (ii) Whether the duty demand for the extended period, and the consequential penalty and interest, were sustainable.

Issue (i): Whether aluminium foil laminated with plastic layers and the resulting pouches were classifiable under chapter 39 or chapter 76.

Analysis: The goods were composite articles consisting of aluminium foil between plastic layers. The plastic predominated by weight and contributed to the essential characteristics of the product. In such a case the classification had to be resolved by applying the interpretative rule governing composite goods and the criterion of essential character. The earlier decisions relied on by the appellant were distinguished on their facts, and the product could not be treated as plain aluminium foil falling under chapter 76.

Conclusion: The classification under chapter 39 was upheld against the assessee.

Issue (ii): Whether the duty demand for the extended period, and the consequential penalty and interest, were sustainable.

Analysis: The department had tested the goods years earlier and was already aware of their composition and the predominance of plastic, while the classification had continued to be approved. In that background, invocation of the extended period on the basis of suppression was not justified. Since the extended demand failed, the penal provisions and interest could not survive on the same footing.

Conclusion: The extended-period demand was barred by limitation, and the penalty and interest were set aside in favour of the assessee.

Final Conclusion: The duty classification was sustained on merits, but the time-bar plea succeeded and the consequential penal and interest demands were deleted, resulting in only a partial allowance of the appeal.

Ratio Decidendi: A composite product is classified according to its essential character, and where the department already knew the product's composition and had approved the classification, the extended period of limitation and related penalty and interest cannot be invoked on the basis of suppression.
