8428.20.00.10 - Conveyors

This HTS category, 8428.20.00.10, specifically covers pneumatic elevators and conveyors. These machines utilize compressed air or vacuum to move materials, typically in enclosed systems. Pneumatic conveyors are designed for the bulk transport of granular, powdered, or pelletized goods, while pneumatic elevators are used for vertically lifting and lowering discrete items or materials within a sealed tube. The defining characteristic of this classification is the reliance on pneumatic force as the primary means of operation for either conveyance or vertical lifting.

It is important to distinguish this category from its sibling, 8428.20.00.50, which covers elevators. While both may involve vertical movement, elevators in the sibling category are generally mechanical in nature, employing cables, chains, or hydraulic systems, and are often designed for the transport of people or goods in open or enclosed cabins. This pneumatic category is solely focused on systems where air pressure differentials are the driving force for material movement.

As this is a leaf node, there are no further subcategories within 8428.20.00.10. Classification within this subheading relies on confirming the pneumatic nature of the elevator or conveyor system and its intended use in material handling. Exclusions from this category would include any systems that use mechanical means for lifting or conveying, even if air circulation is present for other functions.
