8479.89.10.00 - Air humidifiers or dehumidifiers

This HTS code, 8479.89.10.00, specifically classifies air humidifiers and dehumidifiers that are electromechanical appliances with a self-contained electric motor. These devices are designed to regulate the moisture content in the air within enclosed spaces. Humidifiers add moisture to the air, often for comfort or to protect sensitive materials, while dehumidifiers remove excess moisture, preventing mold growth and improving air quality. The key characteristic for classification under this subheading is the integration of an electric motor to power the humidifying or dehumidifying mechanism.

Unlike sibling categories such as floor polishers (8479.89.20.00) or trash compactors (8479.89.55.00), which perform entirely different functions, this subheading is narrowly focused on the manipulation of atmospheric humidity. While other "other" electromechanical appliances might exist within 8479.89.65.00, this specific code carves out a distinct category for devices solely dedicated to controlling airborne moisture levels. The presence of a self-contained electric motor is crucial, differentiating them from passive humidifying or dehumidifying elements.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Therefore, the primary focus for accurate classification under 8479.89.10.00 lies in confirming the appliance's primary function as an air humidifier or dehumidifier and verifying that it is an electromechanical device powered by an integral electric motor, consistent with the scope of the parent category for "Other machines and mechanical appliances: Other: Electromechanical appliances with self-contained electric motor."
