Tariff classification of mill neps and extended limitation fail where records showed bona fide use and department knowledge.

Mill neps were treated as not constituting a separate textile material for exclusionary tariff language, because their commercial and technical character did not show the properties of textile fibres and HSN notes distinguished them from textile fibres and wadding. On that basis, yarn containing artificial staple fibre and polyester staple fibre remained classifiable under the declared tariff heading. On limitation, the assessee's records reflected use of mill neps and the department had inspected the premises and records, so suppression was not inferred and the extended period was not available. The demand was therefore time-barred.

Issues: (i) Whether mill neps constituted a "textile material" so as to exclude the impugned yarn from the heading applicable to yarn containing artificial staple fibre and polyester staple fibre; (ii) Whether the demand was barred by limitation in view of the assessee's bona fide belief and the department's knowledge of the manufacture and use of mill neps.

Issue (i): Whether mill neps constituted a "textile material" so as to exclude the impugned yarn from the heading applicable to yarn containing artificial staple fibre and polyester staple fibre.

Analysis: The governing test was the commercial and technical understanding of the expression and the nature of mill neps themselves. The material relied upon by the Tribunal showed that mill neps are small knot-like aggregates of tightly entangled fibres, and the HSN notes separately categorised mill neps distinct from textile fibres and wadding of textile materials. No evidence was produced to show that mill neps retained the tensile strength, flexibility, and properties associated with a textile material. On that basis, mill neps were treated as not being a separate textile material, but as remaining within the fibre category for classification purposes.

Conclusion: The impugned yarn was held classifiable under the tariff heading applicable to yarn containing artificial staple fibre and polyester staple fibre, and the assessee's classification was accepted.

Issue (ii): Whether the demand was barred by limitation in view of the assessee's bona fide belief and the department's knowledge of the manufacture and use of mill neps.

Analysis: The assessee had maintained registers and other records reflecting the use of mill neps, and the departmental officers had visited the premises and examined the relevant records. The Tribunal accepted that there were reasonable grounds for the assessee to proceed on the belief that mill neps were covered by the declared classification. In these circumstances, suppression could not be inferred and the invocation of the longer period was not justified.

Conclusion: The demand was held to be time-barred and the assessee succeeded on limitation as well.

Final Conclusion: The classification adopted by the department and the consequential duty demand were set aside, and the appeal succeeded on both merits and limitation.

Ratio Decidendi: Mill neps separately recognised in textile classification materials are not to be treated as a distinct textile material for exclusionary tariff language, and where the assessee's treatment of the product is bona fide and fully within the department's awareness, the extended limitation period cannot be invoked.
