8415.90.40.00 - Chassis, chassis bases and outer cabinets

This HTS classification, 8415.90.40.00, specifically covers chassis, chassis bases, and outer cabinets designed for use with air conditioning machines. These components form the structural framework and external housing of air conditioning units, providing support for internal components and protecting them from the environment. They are essential parts that contribute to the overall physical integrity and presentation of the air conditioning machinery.

Distinguishing this category from its sibling, 8415.90.80 ("Other"), is crucial. While 8415.90.80 encompasses a broader range of miscellaneous parts for air conditioning machines that are not specifically defined elsewhere, 8415.90.40.00 is dedicated solely to the structural and protective external elements like the frame and casing. Therefore, if a part is clearly identifiable as a chassis, chassis base, or outer cabinet, it will fall under this more specific classification rather than the more general "Other" category.

As this classification represents a leaf node in the HTS hierarchy, there are no further subcategories for chassis, chassis bases, and outer cabinets. Classification decisions within this code will rely on the clear identification of the imported goods as these specific structural and housing components for air conditioning machinery.
