Tariff classification of hose assembly turned on hardened rubber test reports and was upheld over collateral evidence.

Hose assembly classification turned on whether the goods were made of hardened rubber, because Chapter Note 2(d) of Chapter 40 excluded mechanical appliances of Section XVI made of hardened rubber from Chapter 40. The National Test House and the Rubber Board both reported that the samples were made of hardened rubber, and no contrary laboratory report or technical challenge was produced. Collateral material such as other manufacturers' gate passes and their classification practice was insufficient to displace the government test reports. On that basis, the hose assembly was classified under sub-heading 8431.00, and the assessee's classification was upheld.

Issues: Whether the hose assembly was classifiable under sub-heading 8431.00 or under heading 4009.92, and whether the test reports of the National Test House and the Rubber Board could be accepted for determining whether the goods were made of hardened rubber.

Analysis: Classification depended on whether the goods were made of hardened rubber, because Chapter Note 2(d) of Chapter 40 excluded mechanical appliances of section XVI made of hardened rubber from Chapter 40. The samples sent by the department were tested by the National Test House and were found to meet the requirement of hard rubber, and the Rubber Board also reported that the hose samples were made of hardened rubber. The Revenue did not produce any contra laboratory report or challenge the technical accuracy of these reports, but relied on collateral material such as gate passes of other manufacturers and their classification practice. In the absence of any technical infirmity in the government laboratory reports, those reports could not be discarded.

Conclusion: The hose assembly was rightly classified under sub-heading 8431.00, and the Revenue's challenge to the classification failed.

Final Conclusion: The Revenue appeals were rejected, and the classification in favour of the assessee was upheld.

Ratio Decidendi: Where the department relies on tariff classification turning on the nature of the goods, a government laboratory test report on the very samples under dispute cannot be displaced merely by collateral evidence or the classification adopted for similar goods by other manufacturers, absent any technical challenge or contrary laboratory evidence.
