8503.00.45.00 - For generators suitable for use on aircraft

This HTS category, 8503.00.45.00, specifically classifies parts and accessories for generators that are designed or designated for use on aircraft. This includes components such as stators and rotors that are integral to the functioning of these specialized aircraft generators. The emphasis is on the intended application within an aviation context, distinguishing these parts from those used in ground-based or general-purpose generating equipment.

To differentiate this category from its siblings, note that 8503.00.35.00 covers stators and rotors intended for motors below 18.65 watts, which is a distinct power threshold and application. Conversely, 8503.00.65.00 encompasses "Other" parts and accessories for machines of heading 8501 or 8502, meaning it serves as a residual category for items not otherwise specified. Category 8503.00.45.00 is a specific inclusion for aircraft generator components, separate from general motor parts or other unclassified generator parts.

As this is a leaf node within the HTS structure, there are no further subcategories under 8503.00.45.00. Therefore, classification at this level relies on a definitive determination that the part in question is indeed a stator or rotor intended for use in a generator suitable for aircraft applications. Classification decisions should be supported by technical specifications, original equipment manufacturer documentation, or other evidence demonstrating the specific aviation purpose of the goods.
