Tariff classification of carbon machinery parts turned on Chapter 84 exclusion, confirming Chapter 68 classification

Carbon machinery spare parts imported for use in turbosets and compressors were treated as articles falling within Chapter 68 rather than machinery parts under Heading 84.65. The classification turned on the tariff scheme as a whole, including Section Notes and Chapter Notes, and in particular Note 1(a) to Chapter 84, which excludes articles falling within Chapter 68. Because the goods were accepted to be made of carbon, a mineral substance, the exclusion prevailed and Chapter 84 could not be invoked merely because the goods were fully finished machinery parts. The correct classification was therefore under Heading 68.01/16(1), and the departmental classification was upheld.

Issues: Whether carbon or graphite machinery spare parts imported for use in turbosets and compressors were classifiable under Heading 68.01/16(1) of the Customs Tariff Act, 1975 or under Heading 84.65, and whether Note 1(a) to Chapter 84 excluded such goods from classification as machinery parts.

Analysis: The competing headings were both residuary in character, but tariff classification had to be determined not by the headings alone and also by the Section Notes and Chapter Notes. Note 2 of Section XVI governs the classification of machinery parts, but it is expressly subject to Note 1(a) of Chapter 84, which excludes articles falling within Chapter 68. The goods were accepted to be made of carbon, which was treated as a mineral substance, and therefore as articles falling within Chapter 68. The expression in Note 1(a), namely "other articles falling within Chapter 68", was given its natural meaning so as to exclude all goods covered by Chapter 68 from Chapter 84. If fully finished machinery parts made of carbon were placed under Chapter 84, Note 1(a) would be rendered redundant.

Conclusion: The goods were not classifiable under Heading 84.65 and were correctly classified under Heading 68.01/16(1); the classification adopted by the Department was upheld.

Final Conclusion: The appeals failed because Chapter 84 could not be invoked for fully finished carbon machinery parts that fell within Chapter 68 by reason of the overriding effect of Note 1(a) to Chapter 84.

Ratio Decidendi: Where a tariff note expressly excludes articles falling within another chapter, that exclusion prevails over a more specific residuary heading for machinery parts, and goods covered by the excluded chapter cannot be classified under Chapter 84 notwithstanding their character as machinery parts.
