Vulcanised fibre classification under Chapter 39 confirmed by applying Chapter Notes and HSN consistency principles.

Vulcanised fibre was held classifiable under sub-heading 3920.31 rather than the paper-based sub-heading 4823.90. Chapter Note 1 to Chapter 39 treats vulcanised fibre as included within references to plastics across the tariff nomenclature, and the relevant HSN entries place plates and sheets of vulcanised fibre under Heading 39.20. The tariff was construed consistently with the HSN in resolving the classification dispute, so the product could not be classified under the assessee's claimed heading.

Issues: Whether vulcanised fibre was classifiable under sub-heading 4823.90 as claimed by the assessee or under sub-heading 3920.31 as upheld by the Department.

Analysis: Note 1 to Chapter 39 treats vulcanised fibre as included within references to plastics throughout the tariff nomenclature. The relevant HSN entries place plates and sheets of vulcanised fibre under Heading 39.20, and the tariff is to be construed with reference to the HSN where classification is in dispute. In view of this tariff scheme, the product could not be classified under the paper-based sub-heading claimed by the assessee.

Conclusion: The product was correctly classifiable under sub-heading 3920.31, and the assessee's classification claim was rejected.

Ratio Decidendi: For tariff classification, the Central Excise Tariff must be interpreted consistently with the HSN, and vulcanised fibre is to be treated as falling within Chapter 39 by virtue of the chapter note.
