Specific tariff heading for vulcanised rubber hose assemblies prevails over broader machinery-parts classification despite excavator use.

For tariff classification, a specific heading for vulcanised rubber hose assemblies with fittings prevails over a broader machinery-parts heading. Although the goods were specially designed for excavators and treated commercially as excavator parts, they retained the essential character of hoses and remained classifiable under Heading 4009.92 rather than Heading 84.31. The additional material also failed to prove that the goods were made of hard rubber; the evidence showed only vulcanised hardened rubber and did not displace the Chapter 40 classification. The stated tariff treatment therefore remained applicable.

Issues: (i) whether hydraulic hose assemblies made of vulcanised rubber other than hard rubber were classifiable under Heading 4009.92 or as parts of excavators under Heading 84.31; (ii) whether the additional evidence established that the hose assemblies were made of hard rubber so as to fall outside Chapter 40 and within Chapter 84.

Issue (i): whether hydraulic hose assemblies made of vulcanised rubber other than hard rubber were classifiable under Heading 4009.92 or as parts of excavators under Heading 84.31.

Analysis: The classification had to be determined by the tariff structure, including the section notes, chapter notes and interpretative rules. The goods were hoses with fittings, cut to size for hydraulic use, and retained the essential character of tubes, pipes or hoses. Heading 4009.92 was a specific description for tubes, pipes and hoses of vulcanised rubber with or without fittings, whereas Heading 84.31 was a broader description for parts of machinery. The fact that the assemblies were specially designed for excavators and were commercially treated as parts of excavators did not compel classification with the machine, because an item may be a part of a machine yet remain classifiable under a different heading. On the relevant tariff scheme, the specific description in Chapter 40 prevailed.

Conclusion: The hose assemblies were correctly classifiable under Heading 4009.92 and not under Heading 84.31.

Issue (ii): whether the additional evidence established that the hose assemblies were made of hard rubber so as to fall outside Chapter 40 and within Chapter 84.

Analysis: The additional material did not satisfactorily connect the tested samples with the goods in dispute, and the evidence showed only vulcanised hardened rubber rather than hard rubber. The documents were insufficient to prove that the goods under appeal were made of hard rubber. Since the claim of hard rubber was not established, the earlier tariff analysis continued to apply.

Conclusion: The claim that the goods were made of hard rubber was not proved.

Final Conclusion: The classification under Heading 4009.92 was sustained, and the competing claim to classification as excavator parts under Heading 84.31 was rejected.

Ratio Decidendi: For tariff classification, a specific heading for vulcanised rubber hoses with fittings prevails over a broader machinery-parts heading, and commercial or functional suitability as a machine part does not override the express tariff description.
