Parts of electronic cigarettes and similar personal electric vaporizing devices have a dedicated 10-digit line (8543908865) within heading 854390, the parts heading, rather than under 854340 which covers the complete devices. Correct classification of parts versus finished devices is a common audit issue.
The schedule distinguishes PVD parts at the 10-digit level (8543901100 and 8543901200) to allow different duty treatment for specific PVD component types. Importers should review the tariff schedule notes and any applicable CBP rulings to determine which line applies to their specific component, as misclassification between these lines can affect duty liability.
