Engine parts classification under tariff rules placed automobile pistons in the engine heading, not vehicle accessories.

Automobile pistons used in motor vehicles were held to fall under Heading 84.09 as parts of internal combustion engines, not under Heading 87.14 as vehicle parts. The classification turned on the tariff structure and the section notes to Sections XVI and XVII: Heading 84.09 covers parts used solely or principally with engines, while Section Note 2(e) to Section XVII excludes articles of Headings 84.01 to 84.79 and their parts from that section. A harmonious reading of the headings and notes placed engine pistons in the engine-specific entry, and trade nomenclature as automobile pistons did not override the tariff description.

Issues: Whether automobile pistons used in motor vehicles are classifiable as parts of internal combustion engines under Heading 84.09 of the Central Excise Tariff Act, 1985 or as parts and accessories of vehicles under Heading 87.14.

Analysis: The competing tariff entries were examined along with the section notes to Sections XVI and XVII. Heading 84.09 covers parts suitable for use solely or principally with engines of Headings 84.07 or 84.08, while Heading 87.14 covers parts and accessories of vehicles of Headings 87.11 to 87.13. The Tribunal followed its earlier reasoning that Section Note 2(e) to Section XVII excludes articles of Headings 84.01 to 84.79 and their parts from Section XVII, and that a harmonious reading of the section notes and tariff headings places engine pistons within the engine-related heading rather than as general motor vehicle parts. The fact that the goods were known in trade as automobile pistons did not displace the tariff description adopted in the earlier decision.

Conclusion: The pistons were correctly classifiable under Heading 84.09 and not under Heading 87.14, and the departmental appeal succeeded.
