Machine part classification for carbonaceous molecular sieve upheld as integral, reusable component of nitrogen manufacturing equipment

Carbonaceous Molecular Sieve imported for use in a nitrogen manufacturing generator was treated as an integral, non-consumable component of the machine rather than as a chemical under Tariff Heading 3802.10. The item was installed in cylinders fitted into the generator, operated in a continuous process, was regenerated and reused, and no chemical reaction was involved. On that basis, it was classified as a machine part and qualified for exemption under Notification No. 155/86-Cus.; the chemical classification was rejected.

Issues: Whether Carbonaceous Molecular Sieve imported for use in a nitrogen manufacturing generator was classifiable as a part of the machine and entitled to exemption under Notification No. 155/86-Cus., or was to be classified as a chemical under Tariff Heading 3802.10.

Analysis: The imported Carbonaceous Molecular Sieve was found to be installed in cylinders fitted into the generator and used in a continuous process for manufacturing nitrogen gas. The material was not consumed in the process, but regenerated and reused. The technical opinions on record also stated that no chemical reaction was involved. On that basis, the goods were treated as a component of the nitrogen manufacturing machine rather than as a chemical. The contrary analogy adopted in the impugned order was rejected because the item had a definite functional role as a machine part.

Conclusion: The imported goods were held to be a part of the nitrogen manufacturing machine and entitled to the benefit of Notification No. 155/86-Cus.; the classification under Tariff Heading 3802.10 was not accepted.

Ratio Decidendi: An imported item used as an integral, non-consumable and functionally operative component of a machine is classifiable as a part of the machine and not as a chemical merely because it participates in the manufacturing process.
