Specific tariff classification for hemodialysis accessories prevails over a general heading, securing the linked exemption benefit.

A.V. fistula needles, supported by expert evidence as dedicated for hemodialysis and having no independent function, were treated as accessories for hemodialysis equipment under CTH 90189031. The broader department classification under CTH 90183230 was rejected because a product covered by a specific tariff heading cannot be moved to a more general or residuary heading. As the goods were held to fall within the specific heading, the exemption benefit under the relevant notifications also applied, and the differential duty demand could not be sustained.

Issues: Whether A.V. Fistula Needles were correctly classifiable under CTH 90189031 as accessories for hemodialysis, or under CTH 90183230 as claimed by the department, and whether the exemption benefit under the relevant notifications was available.

Analysis: The imported goods were described as A.V. Fistula Needles and were supported by expert certificates stating that they are used only in hemodialysis and have no independent function. On that basis, the goods were treated as accessories for hemodialysis equipment and not as goods falling under the heading relied upon by the department. The principle applied was that where goods are covered by a specific heading, they cannot be shifted to a more general or residuary heading. Since the goods were found to fall under the specific heading claimed by the appellant, the exemption benefit also followed.

Conclusion: The goods are classifiable under CTH 90189031 and not under CTH 90183230. The appellant is entitled to the exemption benefit, and the department's reclassification and differential duty demand cannot stand.

Final Conclusion: The appeal succeeds and the classification adopted by the original adjudicating authority is restored with consequential relief.

Ratio Decidendi: A product proven to be a dedicated accessory for a specific medical use must be classified under the specific tariff heading applicable to that use, and not under a broader or residuary heading.
