Flywheel classification under customs tariff confirmed for dual mass flywheel as an engine part in heading 8483, not motor vehicle parts.

Dual mass flywheel is classifiable as a flywheel under heading 8483 50 90 because it is an article specifically covered by that heading and functions in the drivetrain and engine system by storing rotational energy and smoothing torque variation. Applying Rule 1 of the General Rules for Interpretation, the relevant section and chapter notes, and the HSN Explanatory Notes, the ruling holds that Note 2(a) of Section XVI supports classification in the goods' own heading. Note 2(e) of Section XVII excludes internal engine parts, including flywheels, from heading 8708 when they are integral engine components, so classification under heading 8708 is rejected.

Issues: Whether dual mass flywheel is classifiable under heading 8483 50 90 as flywheels, or under heading 8708 as parts and accessories of motor vehicles.

Analysis: The product was found to be a flywheel used in the drivetrain and engine system, storing rotational energy and smoothing torque variation. Applying Rule 1 of the General Rules for the Interpretation of the First Schedule to the Customs Tariff Act, 1975, the relevant section and chapter notes, and the HSN Explanatory Notes, articles that are themselves specifically covered by heading 8483 are to be classified in that heading. Note 2(a) of Section XVI supports classification of such goods in their own heading, while Note 2(e) of Section XVII excludes internal parts of engines or motors, including flywheels, from classification as motor vehicle parts under heading 8708 when they constitute integral parts of engines and motors.

Conclusion: The dual mass flywheel is classifiable under heading 8483, more specifically under tariff item 8483 50 90, and not under heading 8708.
