Classification of mobile chilled water plant, not heat exchanger, drove duty recomputation and remand of related reliefs.

Contractual documents, technical literature, and unchallenged expert evidence showed the supplied item was a Mobile Chilled Water Plant with major refrigeration components and a function of generating chilled water, so it was not classifiable as a Heat Exchanger and was placed under Heading 84.18. The contract was on a principal-to-principal basis and required manufacture and supply according to drawings and technical know-how, so the appellants were treated as manufacturers rather than hired labourers. Because duty had to be recomputed on the correct classification, claims for Modvat credit, accessories-related relief, and penalty under Rule 173Q were remanded for fresh consideration.

Issues: (i) whether the goods supplied under the contract were a Mobile Chilled Water Plant or a Heat Exchanger and the consequential tariff classification; (ii) whether the appellants were hired labourers or manufacturers under the contract; (iii) whether the claims relating to Modvat credit, supply of accessories, and redetermination of penalty required reconsideration.

Issue (i): whether the goods supplied under the contract were a Mobile Chilled Water Plant or a Heat Exchanger and the consequential tariff classification.

Analysis: The contract, drawings, technical literature, and the expert affidavit were read together. The evidence showed that the item supplied was a Mobile Chilled Water Plant consisting of major components such as compressor, condenser, evaporator, expansion valve, pumps, controls, and instrumentation, and that its essential function was to generate chilled water. The distinction drawn by the expert between such a plant and a heat exchanger was accepted, and the Department did not dislodge that evidence. The item was therefore not to be treated as a heat exchanger, but as a dutiable article falling under Heading 84.18.

Conclusion: The classification as Heat Exchanger was rejected and the goods were held to be classifiable as a Mobile Chilled Water Plant under Heading 84.18.

Issue (ii): whether the appellants were hired labourers or manufacturers under the contract.

Analysis: The contract was on a principal-to-principal basis and required the appellants to manufacture and supply the plant in accordance with technical know-how, drawings, and schematics. The contractual terms did not show a mere labour arrangement. The work undertaken was manufacturing activity and not the engagement of hired labourers.

Conclusion: The plea that the appellants were only hired labourers was rejected and they were treated as manufacturers.

Issue (iii): whether the claims relating to Modvat credit, supply of accessories, and redetermination of penalty required reconsideration.

Analysis: The authority had not considered the claim for Modvat credit and had not re-examined the benefit claimed in respect of accessories. Since the duty liability had to be recomputed after correct classification, those related claims also required fresh consideration. The penalty under Rule 173Q was to be redetermined after recomputation of duty.

Conclusion: The matter was remanded for recomputation of duty, reconsideration of Modvat credit and accessories-related relief, and redetermination of penalty.

Final Conclusion: The appeal succeeded in part on classification, but the consequential duty, credit, accessories, and penalty issues were sent back for fresh determination.

Ratio Decidendi: Where the contractual documents and unchallenged expert evidence establish that the supplied article is a distinct manufactured plant and not the commodity alleged by the Department, the correct classification must follow the proven functional and technical character of the goods; consequential reliefs depending on the classification must then be reconsidered.
