9902.15.62 - Air conditioning machines, incorporating a refrigerating unit, mounted on wheels or castors, exceeding 17.58 kW per hour (provided for in 8415.82.01)

This HTS category, 9902.15.62, specifically covers large, portable air conditioning units that integrate a refrigeration system and are equipped with wheels or castors for mobility. The defining characteristic for inclusion in this classification is the unit's cooling capacity, which must exceed 17.58 kW per hour. These machines are intended for temporary or localized cooling applications, distinguishing them from permanently installed HVAC systems.

Unlike the broad range of sibling categories found in the main HTS chapters (such as live animals or agricultural products), this classification falls under Chapter 99, which is reserved for temporary legislation and special provisions. This signifies that the tariff treatment or restrictions applied to these specific air conditioning units are not standard but are subject to specific policy directives.

As this is a leaf node, there are no further subcategories within 9902.15.62. Therefore, the focus remains on the precise definition provided, ensuring that importers correctly identify units meeting the horsepower threshold and the portable, wheeled design, and understand that these items are subject to the temporary or special provisions outlined in Chapter 99, rather than the general provisions found in Chapter 84, where similar, but perhaps non-wheeled or lower-capacity units, might be classified.
